3 PLC / CNC Interface3.1 IntroductionThe main function of the integrated software task PLC is to estab-lish communication between the CNC kernel and the machine.

The PLC is the master of the equipment and is responsible for theadjustment of the machine logic to the CNC and for the observ-ance of functional sequences and operation sequence.

For this purpose the PLC uses interfaces to the machine and to theCNC. Via these interfaces it can recognize the current state of themachine and can initiate the necessary action to the CNC and viceversa.

The interface to the machine is realized usually via digital I/O com-ponents, over which digital or analog signals are read (inputs) orset (outputs).

The interface to the PLC is a virtual interface. It is a software built-in communication that requires no I/O components. This manualdescribes the standard PLC-CNC interface.

This internal interface can be addressed from the PLC programoutwards and of course in the same manner in which I/O boardsare addressed for communication with the machine.

Over this interface, the PLC program communicates with the CNCkernel. The CNC kernel ensures that information about currentCNC states is provided and that action initiated by the PLC is exe-cuted.

3.2 Notes

CAUTION!Names Definition

– All the names used in the following descriptionare defined by the files– systemvars.cfglocated under:– C:\Program Files\Power Automation\

IEC1131\IEC1131 EnglThis file may change according to your actualPA software versions.

– In case of doubt, this file has always to bechecked for correct signal names!

CAUTION!Notes for the further signal description– Some of the interface signals are inverted and

called "low-active" signals. Their name endswith the character "n" (lower case), like INE-MERGENCn. They have the meaning "real" iftheir value is 0 (false). The description willrefer to a NOT function.

– The other signals, like IN_START, are "high-active" signals. They have the meaning "real"if their value is 1 (true).

CAUTION!Individual signal description may refer to the"Control Reset" stateThe "Control Reset" state is generated:

– when the CNC is switched on– after loading of new machine parameter values– with a program end code (M2 or M30)

with a manual command via HMI (refer to thePA Operating Manual)

– with the simultaneous action of the keyboard'skeys: [Ctrl] and [R]

– by a PLC command (see " Ä “Mode AdditionalSelection” on page 76")

Any time a Control Reset is active, the CNC givesthis information to the PLC with an interface signal:ON_RESET (see"Ä Chapter 4.2.1.9 “ON_RESET”on page 150" for information about CNC actions incase of "Control Reset".


PLC / CNC Interface

12.01.2017 | 22

3.3 TerminologyThe signal interface has a fixed layout, and therefore it has beenexpanded to 128 DWORDs to make all CNC functions available atthe same time.

All the individual signals (BITs) as well as all the signal groups(DWORDs) have predefined symbolic names. All of them are auto-matically defined as Global Variables for the PLC developmenttool, and do not require any further definition in the PLC program.

CAUTION!– The symbolic names for the CNC input signals

and those of their corresponding DWORDsbegin with the letters IN.

– The symbolic names for the CNC output sig-nals and those of their correspondingDWORDs begin with the letters ON.

To ensure an easy reading of the PLC program, itis recommended not to use your own mnemonicnames starting with IN or with ON.

The standard PLC-CNC signal interface is fully predefined for twoCNC stations. This means all interface BITs and all interfaceDWORDs are defined for station 1 and for station 2.

CAUTION!– The input symbolic names for the second CNC

station begin with the letters I2.– The output symbolic names for the second

CNC station begin with the letters O2.

For further stations, station 3 up to station 8, the PLC-CNC signalinterface defines only symbolic names for DWORDs (group of32 bits).

CAUTION!– The input symbolic names of DWORDs for

station 3 to 8 begin resp. with the letters I3 toI8.

– The output symbolic names of DWORDs forstation 3 to 8 begin resp. with the letters O3 toO8.

4 PLC / CNC - Signal InterfaceThe PLC / CNC signal interface corresponds to a parallel, digitalinterface. Here, mainly single signals are transferred with a directstate or function assignment.

CAUTION!Signal Interface Addressing– Single signals can be individually addressed as

BIT– Single signals are put together in groups of 32,

these groups can be addressed as DWORD

Typical applications are:

n Start and stop of a NC-program processingn Closing and opening of the CNC control loopsn Recognizing of the auxiliary functions („BCD’s“) programmed in

the NC program

CAUTION!The signal interface is made up of two parts:

– CNC inputs: These signals the PLC can onlyspecify and the CNC can only read.

– CNC outputs: These signals the CNC can onlyspecify and the PLC can only read.

CAUTION!Individual signals / grouped signals:

– Many interface signals have individual actionand can be treated individually.

– Other interface signals have meaning that isdependent on other signals; still others must betreated jointly.

An individual note gives explanations each time itis necessary.

12.01.2017 | 31

4.1.1.1 INEMERGENCnThis input signals to the CNC the Emergency Stop state of themachine, usually generated by actuation of Emergency Stop push-buttons or by any safety relay.

Value Description

0 Emergency Stop state is active

1 Emergency Stop state is not active

Value Action in the CNC

0 n Output zero on all axes / spin-dles or D/A outputs

n Lock the CNC emergency staten Stop and lock of any program

executionn Stop of any manual operationn Position loop control is openn Set signals ON_NO_CNTR and

ON_EMERGn Display the status "Emergency

stop" in the standard HMIstatus windows

n Display of machine positions,instead of set positions

0 ® 1 No direct effect

1 No direct effect, emergency stopstate remains locked!


– The PLC must always send the real currentmachine emergency state to the CNC via thissignal to ensure proper safety functions in theCNC

– The Emergency Stop locking inside the CNCcan only be removed by "Control Reset", oncethe input signal INEMERGENCn has got avalue "1" again.

– During Emergency Stop, the axes position arestill measured. Possible movements occurringduring this state (e.g. manual shifting of axes)will be displayed. Thus a new homing of axesis not necessary after the CNC leaves theEmergency Stop state.

» Continued on the next page

NOT In Emergency Stop



12.01.2017 | 32

– The INEMERGENCn signal is not interlockedin the CNC and works always immediately andunconditionally!

– The INEMERGENCn signal does not influencethe CNC safety relay "CNC-Ready".

CAUTION!Starting with PA software version # 3.4.11.1, itbecomes possible to affect the state of the "CNCReady" contact (connector X19 - refer to the PACNC hardware installation manual) according tothe status of the INEMERGENCn input!

– Setting the machine parameter InEStopRea-dyOff to a value different from "0", makes the"CNC Ready" relay drop when the input INE-MERGENCn is set to "FALSE".

– Keeping the default value of the machineparameter InEStopReadyOff ("0"), keeps thestandard behavior of the "CNC Ready" relay,which then depends only on the conditions aslisted in the PA CNC hardware installationmanual.

CNC Ready conditions– The "Power On" relay is switched on.– The watchdog is retriggered, that means the

software is monitored as working properly.– All axes measurement signals are correct.– All axes position loops are under control.– The RMS power supply voltage is within opera-

tion range.– The operating temperature is below +55°C

(+131°F).



12.01.2017 | 33

4.1.1.2 IN_STARTWith this CNC input, the PLC instructs the CNC to execute a"start". Such "starts" are unconditionally necessary for automaticcycles execution (NC program, homing cycle, etc.) The CNC is notable to start such cycles on its own.

Value Description

0 Cycle Start not required

1 The PLC requires a Cycle Start


0 No direct effect

0 ® 1 n Removes the locking of theCycle Stop

n If one of the conditions listed inthe following table is fulfilled,then:– Internal START is executed.– Set signal ON_CYCLEON.– Display the status "CYCLE

ON" in the standard HMIstatus windows.

1 No direct effect


– Before the PLC sends an IN_START, it mustbe ensured that:– all safety conditions according to valid

standards are fulfilled– the machine is ready for the action that will

be executed after the start– The CNC will not execute an incoming

IN_START, if:– the Emergency Stop locking state is active– the signal IN_STOPn has a value "0"– the test operation mode "Without Move-

ments" is active (the signal ON_NO_CNTRis set)

– the CNC is in the operating mode"Memory"


Cycle Start



12.01.2017 | 34

– It is recommended to monitor in the PLC pro-gram that the IN_START request has beenexecuted (e.g. ON_CYCLEON has been set to"1"), and herewith to set the signal IN_STARTback to "0".It is as well possible to generate in the PLCprogram only IN_START pulses, at least aslong as two PLC cycle times.

START requirements¯

Conditions Effect

CNC in MANUAL mode, INCREMENTAL JOG, andthe movement was interrupted by IN_STOPn (FeedHold)

The interrupted incremental jog is continued

CNC in HOMING mode, in basic conditions, and atleast one axis is homing duty

The homing cycle is started

CNC in HOMING mode, the homing cycle wasstarted, and the movement was interrupted byIN_STOPn (Feed Hold)

The interrupted homing cycle is continued

CNC in AUTO mode, SEQ. BLOCK, in basic condi-tions, and an executable NC program is selected

The program execution is started, as long as NCblock changes are allowed (See Ä Chapter 4.1.1.4“IN_TRANSF” on page 39) and NC block move-ments are allowed (See Ä Chapter 4.1.1.5“IN_ENABLE” on page 41)

CNC in AUTO mode, SINGLE BLOCK, in basicconditions, and an executable NC program isselected

The program execution is started; one block is trans-ferred (if IN_TRANSF =1). The execution of the firstblock will require two IN_START rising edges!

CNC in AUTO mode, MANUAL DATA INPUT, inbasic conditions, and no NC block is active

One block is transferred (if IN_TRANSF =1), even ifthe block is empty. The execution of one singleinstruction will require two IN_START rising edges!Thus it is possible to prepare two MDI instructionsbeing executed with three IN_START rising edges

CNC in AUTO mode, SEQ. BLOCK or SINGLEBLOCK or MANUAL DATA INPUT, and a NC blockwas active and interrupted by IN_STOPn (FeedHold)

The execution of the interrupted block is continued(if IN_ENABLE =1). If in fact the block was alreadydone, a new block is transferred (if IN_TRANSF =1)

CNC in AUTO mode, SEQ. BLOCK or SINGLEBLOCK or MANUAL DATA INPUT, and the execu-tion of NC blocks was interrupted by the codes M0or M1 (program stop; ON_PRG_STP is set)

The execution of the following block is continued (ifIN_TRANSF =1)

CNC in AUTO mode, SEQ. BLOCK and a posi-tioning axis was in movement and interrupted byIN_STOPn (Feed Hold)

The movement of the positioning axis is continued,possibly together to other effects (as mentionedabove)

4.1.1.3 IN_STOPn (Inverted)With this CNC input, the PLC instructs the CNC to interrupt anymovements (feed hold). This generates a cycle stop locking thatcan be only cancelled by a following IN_START signal rising edge.

Value Description

0 The PLC requires a Cycle Stop(Feed Hold)

1 Cycle Stop (Feed Hold) is notrequired


0 No signal IN_START can be pro-cessed.

The cycle stop state remainslocked.

0 ® 1 No direct effect.

1 No direct effect.

The cycle stop state remainslocked!

1 ® 0 n Stop of all axes (with themachine pre-defined decelera-tion value), possibly on the pro-grammed path

n Lock the CNC cycle stop staten Set the active federate to 0n Stop of pure NC block transfern Set signals ON_CYCLE_STOPn After deceleration, when all

axes are at a stillstand, resetsignal ON_CYCLEON and setsignal ON_STAND

n Display the status "CYCLESTOP" in the standard HMIstatus windows

NOT In Cycle Stop



12.01.2017 | 37

– By active thread cutting (G33, G34) the actionof IN_STOPn is delayed until the active threadcutting is done. It could possibly be delayed onseveral thread cutting consecutive blocks, ifthere is a direct G33/G34 sequence. Thus thesingle way to stop immediately a thread cuttingsequence is to stop the spindle rotation usingtherefore the signal(s) IN_NULLV01 to 06 (seeÄ Chapter 4.1.12.1 “IN_NULLVxx” on page 83)

– IN_STOPn works as well when the test opera-tion mode "Without Movements" is active (thesignal ON_NO_CNTR is set)

– Spindle rotations are not stopped byIN_STOPn. Thus the single way to stop imme-diately a spindle is to stop the spindle rotationusing therefore the signal(s) IN_NULLV01 to06 (see Ä Chapter 4.1.12.1 “IN_NULLVxx”on page 83)Important: The PLC logic should take care ofwaiting for the real standstill of the axes to stopthe spindles (wait for ON_CYCLEON = 0 or forON_STAND = 1)!

– In cycle stop state, the axes position loops arestill closed

– The cycle stop state can be released:– by Control Reset– by IN_START if the test operation mode

"Without Movements" is not active– by the softkey "Start Test" in test operation

mode "Without Movements"



12.01.2017 | 38

4.1.1.4 IN_TRANSFWith this CNC input, the PLC allows the CNC to transfer blocksfrom the preparation level to the execution one. If the PLC gives tothis signal a value = 0 the possibly active block will be executed tillits end, but the processing of the following blocks is interrupted.This signal is mainly used for NC program interruption when it isnecessary to wait for an external machine event.

Value Description

0 Transfer of NC blocks is not allowed

1 Transfer of NC blocks is allowed


0 n A possibly active NC block willbe executed till its end

n Further block execution isstopped

n Stop of all axes (with themachine pre-defined decelera-tion value), at the end of theactive NC block

n Set signals ON_TRANSFn After deceleration, when all

axes are at a stillstand, setsignal ON_STAND(ON_CYCLEON remains = 1)

0 ® 1 If the CNC is in AUTO mode, SEQ.BLOCK, SINGLE BLOCK orMANUAL DATA INPUT, the pos-sible interpolation in the active blockis continued

1 No direct effect


– The block transfer might not work immediately:– by active Look Ahead (G9), and if the path

speed is too high to allow a proper axesdeceleration before the end position of theactive block; further blocks will be pro-cessed until the zero speed can bereached at the end of a block

– by active thread cutting (G33/G34) directsequence; the sequence will continue untilthe end of the thread cutting sequence


Allow Execution Of Next Block



12.01.2017 | 39

– IN_TRANSF is ignored in MANUAL Jogmodes and in HOMING mode

– IN_TRANSF works as well in the test operationmode "Without Movements"

– Movements of positioning axes are not influ-enced by IN_TRANSF

– The signal ON_CYCLEON remains = 1 bymissing IN_TRANSF



12.01.2017 | 40

4.1.1.5 IN_ENABLEWith this CNC input, the PLC instructs the CNC to stop the axesmovements during a program execution.

Value Description

0 Interpolation speed is set to zero

1 Interpolation is allowed


0 n Path interpolation cannot beexecuted

n Stop of all axes (with themachine pre-defined decelera-tion value)

n After deceleration, when allaxes are at a stillstand, setsignal ON_STAND(ON_CYCLEON remains =1)

0 ® 1 If the CNC is in AUTO mode, SEQ.BLOCK, SINGLE BLOCK orMANUAL DATA INPUT the transferof the next block is done and theprogram execution continues.

1 No direct effect


– With activated thread cutting (G33, G34) theaction of IN_ENABLE is delayed until theactive thread cutting is done. It could possiblybe delayed on several thread cutting consecu-tive blocks, if there is a direct G33/G34sequence. Thus the single way to stop immedi-ately a thread cutting sequence is to stop thespindle rotation using therefore the signalsIN_NULLV01 to IN_NULLV06 (see"IN_SPINDLE", page 52)

– IN_ENABLE is ignored in MANUAL Jogmodes and in HOMING mode

– IN_ENABLE works as well in the test operationmode "Without Movements"

– Movements of positioning axes are not influ-enced by IN_ENABLE

– The signal ON_CYCLEON remains "=1" bymissing IN_ENABLE

4.1.1.6 IN_NO_HDW_RESETWith this CNC input, the PLC ensures that the handwheel pres-ently selected by this station (e.g. station 1) remains active evenwhen the operator selects another station in display.

Value Description

0 By station deselecting, the hand-wheel will be reset and not activeanymore

1 By station deselecting, the hand-wheel will be kept active with itsactual selection values (axis, factor)

4.1.1.7 IN_PLAYBACKOn the rising edge of this CNC input, when the playback mode isactive, a new NC block, with actual axes positions will be added inthe program being edited.

Value Description

4.1.2.4 IN_BCDSTRB2_FWDBy default the CNC does output programmed BCD-code to thePLC only by the first NC-block processing. While executing theNC-blocks in backward direction and after return to forward direc-tion, the BCD-codes will not be output again.

When it is useful to get the BCD-codes again during backward orforward execution of NC-blocks, the PLC can request it with thesetwo signals.

Value Description

0 BCD-codes will be output to thePLC only during the first NC-blockprocessing

1 BCD-codes will be given to the PLCagain, after a backward movement,when forward execution isrestarted.

For detailed information about how BCD-codes areoutput to the PLC: See Ä Chapter 4.2.3 “BCD Pro-cessing” on page 165.

4.1.2.6 IN_PLC_NO_RETREATThis input allows the PLC to select an ending strategy for the PLCfunction Move_Interpolating_Axis (see Ä Chapter 4.1.16 “CNCInput DWORD: IN_IPOMVMT” on page 91).

Value Description

0 By end of the Move_Interpo-lating_Axis, the axis will retreat toits last position before the call of thefunction.

1 By end of the Move_Interpo-lating_Axis, the axis will stay in theposition reached with the call of thefunction, and the program will bereinterpreted.

When ending the function without moving back tothe path, the part program is interpreted again fromthe current active block. In the HMI this block ismoved to passive level and CYCLE OFF is set. Tocontinue the part program, the PLC must sendIN_START signal to CNC.

4.1.2.7 IN_ALARM_STOPFor safety reasons, the machine might have to stop under control(not in emergency stop) with higher acceleration values than thenominal ones. This signal works basically like the IN_STOP signal,but it is not inverted.


0 No direct effect.

The cycle stop state remainslocked!

0 ® 1 n Stop of all axes with themachine pre-defined alarm stopdeceleration value.

n Lock the CNC cycle stop state.n Set the active federate to 0.n Stop of pure NC block transfer.n Set signals ON_CYCLE_STOP.n After deceleration, when all

axes are at a stillstand, resetsignal ON_CYCLEON and setsignal ON_STAND.

n Display the status "CYCLESTOP" in the standard HMIstatus windows.

1 No signal IN_START can be pro-cessed. The cycle stop stateremains locked.


– By active thread cutting (G33, G34) the actionof IN_ALARM_STOP is delayed until theactive thread cutting is done. It could possiblybe delayed on several thread cutting consecu-tive blocks if there is a direct G33/G34sequence. Thus the single way to stop immedi-ately a thread cutting sequence is to stop thespindle rotation using therefore the signal(s)IN_NULLV01 to IN_NULLV06 (See Ä Chapter4.1.12 “CNC Input DWORD: IN_SPINDLE”on page 82).

– IN_ALARM_STOP works as well when the testoperation mode "Without Movements" is active(the signal ON_NO_CNTR is set).


Activate The "Alarm Stop" Mode



12.01.2017 | 53

– Spindle rotations are not stopped byIN_ALARM_STOP. Thus the single way tostop immediately a spindle is to stop thespindle rotation using therefore the signal(s)IN_NULLV01 to IN-NULLV06 (See Ä Chapter4.1.12 “CNC Input DWORD: IN_SPINDLE”on page 82).Important: The PLC logic should take care ofwaiting for the real standstill of the axes to stopthe spindles (wait for ON_CYCLEON = 0 or forON_STAND = 1)!

– In cycle stop state, the axes position loops arestill closed.

– The cycle stop state can be released:– by Control Reset– by IN_START if the test operation mode

"Without Movements" is not active– by the softkey "Start Test" in test operation

mode "Without Movements"

– The deceleration values in case of an alarmstop are defined by the machine parameters:– AlarmStopAccelFactor– AlarmStopGainFactor

4.1.2.8 IN_PLC_MOV_NO_OVRThis input allows the PLC to determine if feed override should beactive or not during a movement done with the PLC functionMove_Interpolating_Axis (See Ä Chapter 4.1.16 “CNC InputDWORD: IN_IPOMVMT” on page 91).

Value Description

0 During a Move_Interpolating_Axismovement, the feed override isactive. The movement speeddepends on the programmed speedand on the feed override value.

1 During a Move_Interpolating_Axismovement, the feed cannot beoverridden. It is executed at the pro-grammed speed.

4.1.3 CNC Input DWORD: IN_DRIVEONWith this CNC input, the PLC instructs the CNC to close the posi-tion control loop of each axis.

CAUTION!In case of digital interface toward the axes drivesPA SDITM drives or SERCOSTM drives, the CNCsystem will send an "enable" command to thedrives when these inputs are set "1" (true).

See Ä Chapter 4.2.9 “CNC Output DWORD:ONREADY” on page 181.

The following signals belong to the content ofDWORD: IN_DRIVEON (see Ä Table 5 “IN_DRIVEON”on page 56).

n Set signal ON_POS_xx of theaxis (excepted if the test mode"Without Movements" is active)

0 ® 1 n When not in Emergency Stop,the geometric preparation issynchronized with the actualmachine position of all axes

n When not in test mode "WithoutMovements", close the positionloop of the axis on the effectiveactual machine position

n By digital drive interface only:send "enable" command to thedrives

1 When Homing mode is active,same effects as for the transition0®1


– If the CNC is in AUTO mode, SEQ. BLOCK,SINGLE BLOCK or MANUAL DATA INPUT atransition 0®1 of one of these bits should onlybe done– OR if yet no NC blocks have been pro-

cessed– OR if this occurs as a NC block is active in

which a specified M-code is programmed.The value of this M-code is predefined bymachine parameter (DriveOnAppl).

12.01.2017 | 58

Refer to the PA Programming Manual formore explanation.Otherwise the transition 0®1 of one ofthese bits, due to the synchronization ofthe geometry preparation and possible nonexecution of already prepared blocks, itmay occur CNC error messages as well asaxes movements and/or PLC actions, all ofthem not expected by the NC programmer

– By Gantry axes, the position loop control bit ofany of the two gantry axes has the describedeffects on both axes!

– The signal ON_NO_CNTR is not set when one(or more) of the position loop control bit(s)is/are missing.

– An axis with missing position loop control bitwill cause no error if this axis is programmed inthe active NC program. It will only result in anon executed movement.

– A spindle, even when an axis output interfaceis used, is not influenced by the control loopcontrol bit.

4.1.4.1 IN_DRENxx

Value Description

0 Axis movement is not allowed

1 Axis movement is allowed


0 Any manual or homing movementof the axis is not allowed

0 ® 1 If any manual movement is pres-ently requested, as well during thehoming cycle, as if a manual jog iscommanded (by the operator), themovement is started and the signalON_CYCLEON is set.

1 No direct effect

1 ® 0 If any manual movement is pres-ently executed, as well during thehoming cycle, as if a manual jog iscommanded (by the operator), themovement is stopped (with themachine pre-defined decelerationvalue).

– In the AUTO operation modes, the feed enablecontrol bits have influence only:– on positioning axes– on the programmed homing cycle (G74)

– The feed enable control bits are valid even inthe test operation mode "Without Movements"

– A spindle, even when an axis output interfaceis used, is not influenced by the feed enablecontrol bit.

For given PA software functions, like "TangentialTracking" (code 400407), or "Distance Regulation(code 400409 or 400410), because these functionsare generating movements of axes that are notlisted in the program, the IN_DRENxx signal ofindividual axes is necessary even in AUTO mode.

Therefore in the functional tables, the following ter-minology will apply:

– 0: the bit has the value 0– 1: the bit has the value 1– x: the bit's value is not relevant

4.1.9.1 External Mode SelectionThe function "External Mode Selection" has three basic states:

12.01.2017 | 69

Basically every time the PLC requires an external mode selection,the CNC will give feedback for effective mode selection or will indi-cate an error situation if the present machine and NC situationdoes not allow the requested selection.

CAUTION!For some of the selected modes, there are directoutput bits of the NC confirming the selection:

– e.g. ON_AUTO, ON_JOG_CONTFor description see Ä Chapter 4.2 “Single signalsfrom CNC to PLC” on page 139.

CAUTION!Additionally there is an output DWORD calledONEXTMODE that mirrors exactly the PLC requestas long as the request can be executed. Thus,using this NC output, the PLC can check if therequested command is executed or not:

– if ONEXTMODE ¹ IN_EXTMODE: selectionnot yet done or not possible

– if ONEXTMODE = IN_EXTMODE: selectiondone

Examples



12.01.2017 | 72

When using only the selection of IN_EXTMODE = 2#0000000001= 1 (dec) that’s meaning MANUAL mode is selected, but withoutmovement activation, then JOG movements, as well continuous asincremental can be started with the DWORD's IN_JPLS andIN_JMNS (See Ä Chapter 4.1.20 “CNC Input DWORD: IN_JPLS”on page 99 and Ä Chapter 4.1.21 “CNC Input DWORD: IN_JMNS”on page 101).

CAUTION!The use of IN_EXTMODE = 1 together withIN_JPLS and IN_JMNS allows:

– simultaneous jog command for several axes– handling (and not only 1 out of 4 preset

speeds)

Manual jog or handwheel selection will lead to errors or impossibili-ties in following cases:

n A cycle is presently active (signal ON_CYCLEON =1):– Changing NC modes is then not possible. The active cycle

must be first either ended, or interrupted.n The NC is in Emergency Stop state:

– Neither axis selection, nor jog movements can be done.n The CNC is in Cycle Stop state:

– No jog movements can be executed.n The PLC tries to jog an axis as the homing cycle has still not

been done:– Homing cycle of all mandatory axes must be done before.

n The PLC tries to select a non-existing axis.

CAUTION!The PLC logic must especially take care of a "Con-trol Reset" command!

Continuing command with IN_EXTMODE = 6would require many operator actions (SeeÄ Chapter 4.2.1.9 “ON_RESET” on page 150).

It is there really necessary to be sure to reset thePLC IN_EXTMODE as soon as its feedback hasbeen given by the PLC.

External mode selection will lead to errors or impossibilities in fol-lowing cases:

n The PLC tries to select the Homing mode for a non-existingaxis, or for an axis that has not been defined as homing man-datory.

n The PLC tries to select an AUTO mode as the homing cyclehas still not been done:– Homing cycle must be done before.

n A cycle is presently active (signal ON_CYCLEON =1):– Changing NC modes is then not possible.

The active cycle must be first either ended, or interrupted.n The PLC tries to select the Manual Release mode as the

homing cycle has already been done:– This is nonsense: Manual Release mode makes sense only

to move axes in a safe position under the responsibility ofthe operator when starting the homing cycle is presentlynot safe.

4.1.9.4 External Program SelectionThe second part of the DWORD IN_EXTMODE allows the PLC toselect NC programs for AUTO execution, as long as these pro-grams are located in the NC memory.

CAUTION!This way of selecting program is an older function,still supported by the PA CNC software.

There is a new PLC Function that allows a pro-gram selection in a much more convenient way,and furthermore selection of programs located notonly in the NC memory, but as well on the harddisk.

CAUTION!Instead it is strongly suggested to use the PLCfunction block "SELECT_NC_PROGRAM" everytime the PLC has to select a NC program for exe-cution.

This PLC function allows a program selection in amuch more convenient way, and makes possiblethe selection of programs located not only in theNC memory, but as well on the hard disk.

4.1.11.1 IN_SWAXxxWith the six first bits of DWORD IN_SW_AXES, the PLC mayrequire, when the option "spindle / rotary axes switch" is activated,to switch a rotary axis to switch in spindle mode and back to axismode.

Value Description

0 The axis number xx is set in axismode

1 The axis number xx is set in spindlemode

– Switching axis from axis mode to spindle mode(or back) via PLC command is only possible inMANUAL mode.

– Such a switch is not allowed in HOMING modeor in AUTO mode.

– Switching axis from axis mode to spindle mode(or back) can be done in AUTO mode via pro-gram commands (M-Codes). Refer to the PAsoftware function manual of this option (code400304) for detailed information.

– The limitation for the switching over 6 axesonly is due to the ability of PA CNCs to controlup to 6 spindles.

– The proper execution of a switch commandshould be monitored by the CNC acknowledge-ment ON_SWAX. See also "ON_SW_AXES",Ä Chapter 4.2.20 “CNC Output DWORD:ON_SWAX” on page 211.

1 No direct effect.

1 ® 0 The analog command towards thespindle driver is inverted immedi-ately without ramp

CAUTION!Spindle Reverse Commands are not interlocked inthe CNC and work unconditionally!

– As the spindle reverse command works uncon-ditionally, one must be aware that the effectivespindle direction of rotation does depend onthe program (usually M3 / M4) and on thevalue of the IN_REV_xx bit.

– With a spindle without feedback, and by activeselection of feed rate per revolution (G95), aspindle reverse command will have no influ-ence on the direction of the interpolation.

– With a spindle with feedback, and by activeselection of feed rate per revolution (G95), orby active thread cutting (G33/G34), a spindlereverse command will have no influence on thedirection of the interpolation, but the interpola-tion will be sloped down and up againaccording to the spindle speed behavior duringreversion.

4.1.13 CNC Input DWORD: IN_PARKINGWith this CNC input, the PLC instructs the CNC to set the corre-sponding axis in PARKING mode.

In PARKING mode it is possible to disconnect the feedback of anaxis without an error statement from the CNC, which would other-wise detect a measuring system error that will result in a falling ofthe CNC-Ready safety relay.

CAUTION!Spindle Reverse Commands are not interlocked inthe CNC and work unconditionally!

– In case analog axes, and when encoder meas-uring signals are delivered by the drive, it maymake sense to set these bits TRUE until thedrive units are able to deliver a proper and faultfree measuring system output. The CNCsupervising hardware might be faster than thedrives and would then detect wrong measure-ment input status (like cable cut or wrongchanges). As long the input bits IN_PARKxxare set this supervisor information will have noeffect.

If PLCMirrorReset = 0, then the mirroring inputswill not be executed by the CNC.

As consequence, axes mirrored by PLC remainmirrored after a Control Reset! Cancelling axis mir-roring can be done only by the PLC!

– The CNC will mirror axes only in AUTO mode,and only when no cycle is active(ON_CYCLEON =0)

– Mirrored axes remain mirrored after a ControlReset. They will only be reset on normal opera-tion (non mirrored) by changeover to MANUALmode or to Homing cycle

– Mirroring status can as well be changed by NCprogram

Value Description

0 Axis is in CNC interpolation mode

1 Axis is controlled by the PLC

– The CNC can only control an axis in interpola-tion as long as the corresponding bitIN_IPOMTxx is zero

– Once its IN_IPOMTxx bit is set, any interpola-tion movement is blocked:– If there is no PLC command pending, the

axis is just stopped– If a "Move_Interpolating_Axes" command

as already been activated, the commandedmovement will start

– When the IN_IPOMTxx bit is reset to "0", and ifthe PLC command is not yet finished, themovement is stopped. When the control bitbecomes "1" again, the PLC movement is con-tinued

– When the IN_IPOMTxx bit is reset to "0", and ifthe PLC command is finished(ON_PLC_IPO_ENDP_xx is True), the axis willeither retreat to its starting position, or stay inplace: this depends on the control bitIN_PLC_NO_RETREAT (see Ä Chapter4.1.2.6 “IN_PLC_NO_RETREAT” on page 52):– If IN_PLC_NO_RETREAT = "0":

And if there is no NC program active, theaxis stops and keeps its new positionAnd if there is a NC program active, andthere is no movement (CYCLE STOPorCYCLE OFF is active) then the moved axisretreats to its last NC position and the pro-gram execution is released again.

– If IN_PLC_NO_RETREAT = "1":The moved axis stays in its PLC positionA possible running NC program will be exe-cuted with positions shifted by the PLCmovement

4.1.27.1 IN_CANCELBLKWith this input, the PLC is able to abort an active block in execu-tion. This means that from the rising edge of the signals the rest ofthe block will be ignored. The signal generates an internal cyclestop, and further block execution will only be possible with anincoming IN_START.


0 No direct effect

0 ® 1 The presently active block is imme-diately interrupted and a blocktransfer is done ® the followingblock becomes herewith active.

1 Internal Cycle Stop is active.


– These commands will only work in automaticmodes (automatic sequential or single blockand manual data input)

– The PLC gets feedback of its request in bothcases with the signal "ON_CANCELBLK" (seeÄ Chapter 4.2.19.1 “ON_CANCELBLK”on page 205). The PLC should always wait forthis feedback before repeated cancel blockrequest!

– A repeated rising of IN_CANCELBLK whenstill ON_CANCELBLK is not TRUE, will causean error:– 863: “Cancel block is active. No new

requests possible”– A repeated (and allowed) rising of IN_CAN-

CELBLK will result in repeated block cancel-ling: it is thus possible to cancel several blockswith this input

– Repeated rising of IN_FINISH_ACT_BLK willresult in the cancellation of only one block. Thenext block should be started before being can-celled if necessary

4.1.27.2 IN_SINGLE STEPWith this input, the PLC can request a switch in Interpreter SingleStep mode. This mode differs from the single block mode select-able from the HMI in the way that cycle blocks are then executedas well in single block mode.

Thus this Interpreter Single Step mode makes sense especiallyfor cycle program debugging.

When in Interpreter Single Step mode, the execution of the nextblock cannot be started with IN_START. Standard blocks (ISOblocks) execution is submitted to the usual PLC control signals(like IN_TRANSF and IN_ENABLE).

4.1.27.3 IN_IPR_DO_STEPWith this input, the PLC can request a switch in Interpreter SingleStep mode. This mode differs from the single block mode select-able from the HMI in the way that cycle blocks are then executedas well in single block mode.

Thus this Interpreter Single Step mode makes sense especiallyfor cycle program debugging.

When in Interpreter Single Step mode, the execution of the nextblock cannot be started with IN_START. Standard blocks (ISOblocks) execution is submitted to the usual PLC control signals(like IN_TRANSF and IN_ENABLE).

– The PLC gets feedback of the InterpreterSingle Step mode request with the signal"ON_IPR_DO_STEP" (see Ä Chapter 4.2.19.5“ON_IPR_DO_STEP” on page 207). The PLCshould always wait for this feedback before thenext single step operation request!

– This might be interesting when using the Inter-preter Single Step mode to use the PLC to setprogram break points: See Ä Chapter 5.1.8“Program break points” on page 256.

4.1.27.4 IN_PLC_SET_AXPOSThis bit allows the PLC to set an absolute machine position of anaxis. The axis to be set and the position to be set are defined resp.by "SET_AXPOS_INDEX" and "SET_AXPOS_VALUE".

Value Description

0 No set position command

1 The PLC requests an axis positionset

– The Set Axis Position command will be exe-cuted by the CNC only if the bit of"IN_DRIVEON" (See Ä Chapter 4.1.3 “CNCInput DWORD: IN_DRIVEON” on page 56)corresponding to the axis whose position hasto be set, is set to 0 (false).

– This signal should be reset by the PLC whenthe feedback "position set done" is given via"ON_PLC_SET_AXPOS" (See Ä Chapter4.2.19.6 “ON_PLC_SET_AXPOS”on page 208).

– This PLC command has the same effect as theoperator command: MANUAL ® S7 Auxiliaryfunctions ® S4 Cancel Manual Offset

– The PLC gets acknowledgment of the functionbeing executed with "ON_DEL_MAN_OFFS"(See Ä Chapter 4.2.19.9“ON_DEL_MAN_OFFS” on page 209), andshould use this feedback to reset the com-mand.

4.1.27.5 IN_HIDE_IMBLK / IN_HIDE_IMBLKn

Intermediate blocks are blocks that are not pro-grammed, but automatically created by the inter-preter for intermediate calculations (e.g. by G92blocks).

Each of these input pairs allows the PLC to give specific instruc-tions to the CNC, usually done by the operator in the standardHMI.

By the same means, it is possible for the PLC to allow or to disablethe operator to do the corresponding action in the standard HMI.

For each of these pairs there is a positive signal and an invertedsignal (mnemonic name ending with the character "n").

CAUTION!The ability for the operator and for the PLC toselect / unselect the display of intermediate- and /or cycle-blocks is determined by the machineparameter HideIntermediateCycleBlocs.

4.1.27.6 IN_HIDE_CYBLK / IN_HIDE_CYBLKn

Cycle blocks are blocks where only operations onprogram variables are done. These blocks arecharacterized by a "*" in front of their blocknumber.

Each of these input pairs allows the PLC to give specific instruc-tions to the CNC, usually done by the operator in the standardHMI.

By the same means, it is possible for the PLC to allow or to disablethe operator to do the corresponding action in the standard HMI.

For each of these pairs there is a positive signal and an invertedsignal (mnemonic name ending with the character "n").

4.1.27.7 IN_FINISH_ACT_BLKWith this input, the PLC is able to abort an active block in execu-tion. This means that from the rising edge of the signals the rest ofthe block will be ignored. The signal generates an internal cyclestop, and further block execution will only be possible with anincoming IN_START.


0 No direct effect

0 ® 1 The presently active block is imme-diately interrupted but no blocktransfer follows ® the block is fin-ished. The next block will becomeactive only after the next incomingIN_START

1 Internal Cycle Stop is active


– These commands will only work in automaticmodes (automatic sequential or single blockand manual data input)

– The PLC gets feedback of its request in bothcases with the signal "ON_CANCELBLK" (seeÄ Chapter 4.2.19.1 “ON_CANCELBLK”on page 205). The PLC should always wait forthis feedback before repeated cancel blockrequest!

– A repeated rising of IN_CANCELBLK whenstill ON_CANCELBLK is not TRUE, will causean error:– 863: “Cancel block is active. No new

requests possible”– A repeated (and allowed) rising of IN_CAN-

CELBLK will result in repeated block cancel-ling: it is thus possible to cancel several blockswith this input

– Repeated rising of IN_FINISH_ACT_BLK willhave as result the cancelling of only one block.The next block should be started before beingcancelled if necessary

4.1.27.8 IN_DEL_MAN_OFFSThis input allows the PLC to delete axes offset that could be setfrom manual movements during automatic program execution(refer to the PA Operating Manual).

CAUTION!As the operator is able to create program path off-sets by the means of manual movement during aprogram execution, it might be of sense to deletethese offsets after the program end withoutmachine movements (like it occurs when using the"Retreat" mode).

Value Description

0 No direct effect

1 Clear the axes offsets

– This PLC command has the same effect as theoperator command: MANUAL ® S7 Auxiliaryfunctions ® S4 Cancel Manual Offset

– The PLC gets acknowledgment of the functionbeing executed with "ON_DEL_MAN_OFFS"(See Ä Chapter 4.2.19.9“ON_DEL_MAN_OFFS” on page 209), andshould use this feedback to reset the com-mand.

4.1.27.9 IN_MP_CHANGE_ACKThis input allows the PLC to ask if a machine parameter change isjust being done (to avoid e.g. other function block commands to theCNC kernel).

Value Description

0 No direct effect

1 Request information about currentmachine parameter change

The PLC gets feedback with the signal"ON_MP_CHANGE" (See Ä Chapter 4.2.19.10“ON_MP_CHANGE” on page 210) and should usethis feedback to reset the command.

4.2 Single signals from CNC to PLCGenerally the CNC sends information to the PLC about the presentstatus of the CNC as well as handshaking signals allowing the PLCto check the correct realization of its commands.

There is no need to use any of these signals. ThePLC programmer is solely responsible for thechoice of the signals he will consider in his pro-gram.

The level of safety and the accuracy of the infor-mation given via PLC messages to the operator orto the maintenance personnel are very stronglyinfluenced by the number of CNC feedbacks usedin the PLC program

The following existing signals (DWORDs) which are sent from theCNC to the PLC exist in the PLC/CNC-Signal Interface (seeÄ Table 53 “DWORDs” on page 139).

4.2.1.1 ON_CYCLEONThis signal informs whether any activity occurs in the CNC whichhas consequences for the machine.

Value Description

0 There is no functional activity in theCNC

1 The CNC is executing:

n a manual movement (jog contin-uous or incremental)

n a homing cyclen a program sequential or single

block or MDI

– The PLC should use this signal to monitor theexecution of a start requested with IN_START(See Ä Chapter 4.1.1.2 “IN_START”on page 34).

– This signal is valid as well when the test opera-tion mode "Without Movements" is active.

Cycle Is Active



12.01.2017 | 143

4.2.1.2 ON_STOPNCn (Inverted)This signal is given by the CNC when the test operation mode"Without Movements" is active.

In this mode, two additional softkeys are displayed in the menu"AUTO" and "Program Process 1":

n the softkey 8 is called "STOP TEST".

Value Description

0 The softkey "Stop Test" isdepressed

1 The softkey "Stop Test" is notdepressed

– The CNC does not execute directly the actionrequested by the operator! The signalON_STOPNCn indicates only this request tothe PLC program!

– The PLC should use this signal to commandthe execution of the stop with IN_STOPn (SeeÄ Chapter 4.1.1.3 “IN_STOPn (Inverted)”on page 37)

Cycle Stop Command



12.01.2017 | 144

4.2.1.3 ON_STARTNCThis signal is sent by the CNC when the test operation mode"Without Movements" is active.

In this mode, there are two additional softkeys displayed in themenu "AUTO" and "Program Process 1":

n the softkey 7 is called "START TEST".

Value Description

0 The softkey "START TEST" is notdepressed

1 The softkey "START TEST" isdepressed

– The CNC does not execute directly the actionrequested by the operator! The signalON_STARTNC indicates only this request tothe PLC program!

– The PLC should use this signal to commandthe execution of the start with IN_START (SeeÄ Chapter 4.1.1.2 “IN_START” on page 34).

Cycle Start Command



12.01.2017 | 145

CNC Operating Modes



12.01.2017 | 146

4.2.1.5 ON_CNC_CHAN_ACTThis signal indicates whether the station is presently selected forits display by the HMI.

Value Description

0 The station is not displayed on theHMI

1 The station is displayed on the HMI

– By single station configuration, this signal isalways true

– By two station configuration as example, if theHMI displays the data of the second station:– ON_CNC_CHAN_ACT = False– ON_CNC_CHAN_ACT = True

4.2.1.6 ON_EMERGThis signal shows the present Emergency Stop status of the CNC.It reflects the combination of the input signal INEMERGENCn (SeeÄ Chapter 4.1.1.1 “INEMERGENCn” on page 32) and of theinternal emergency stop conditions of the CNC (servo errors ormeasuring system errors).

Value Description

0 The CNC is not in Emergency Stop

1 The CNC is in Emergency Stop

Even if there are no internal emergency stop con-ditions and if the input signal INEMERGENCn istrue, this output signal will remain false until thenext Control Reset (See Ä Chapter 4.1.1.1 “INE-MERGENCn” on page 32)!

CNC Channel

Emergency Stop



12.01.2017 | 147

4.2.1.7 ON_PRG_STPThis signal reflects the program's stop status. A program stop isgenerated by an occurrence of either M00 or M01 in the programbeing executed (as long as the optional stop has been activated -See Ä Chapter 4.1.1.12 “IN_M1STOP / IN_M1STOPn”on page 46).

Value Description

0 The CNC is in AUTO (continuous,single or MDI) and the running pro-gram is not stopped

1 The CNC is in AUTO (continuous,single or MDI) and the running pro-gram is stopped

– This output is set only after the block con-taining the code M00 or M01 has been fin-ished.

– An occurrence of M00 or of M01 can as well bedecoded in the PLC program with the BCDcode output signals (See Ä Chapter 4.2.3“BCD Processing” on page 165). In this casethe PLC programmer must be aware that theBCD-strobe is always given at the beginning ofthe block!

– This output will be reset to false as soon as anew cycle start occurs (See Ä Chapter 4.1.1.2“IN_START” on page 34), a Control Reset isexecuted, or the operator selects another oper-ating mode than AUTO.

– This output is valid as well in the operating testmode "Without Movements".

– Further information about the M00 and the M01can be found in the PA Programming manual.



Program Stop Is Active



12.01.2017 | 148

4.2.1.8 ON_PRG_ENDThis signal reflects the program's end status. A program stop isgenerated by an occurrence of either M02 or M30 in the programbeing executed.

Value Description

0 The CNC is in AUTO (continuous,single or MDI) and the running pro-gram is not finished

1 The CNC is in AUTO (continuous,single or MDI) and the running pro-gram is finished

– This output is set only after the block con-taining the code M02 or M30 has been fin-ished.

– An occurrence of M02 or of M30 can as well bedecoded in the PLC program with the BCDcode output signals (See Ä Chapter 4.2.3“BCD Processing” on page 165). In this casethe PLC programmer must be aware that theBCD-strobe is always given at the beginning ofthe block!

– This output will be reset to false as soon as anew cycle start occurs (See Ä Chapter 4.1.1.2“IN_START” on page 34), or a Control Reset isexecuted, or the operator selects another oper-ating mode than AUTO.

– This output will be set only at the end of themain program. Subprograms called inside amain program have as well an M02 or an M30at their end; in this case however these codeshave for single effect a jump back into thecalling program and are not reflected by theprogram end signal!


– There is no difference between M02 and M30.The two codes exist only for historical reasonsand upgrade compatibility.




Program End Is Active



12.01.2017 | 149

4.2.1.9 ON_RESETThis signal indicates to the PLC program that a Control Reset isbeing executed.

Value Description

0 No Control Reset

1 Control Reset is being executed

– This output is set as long as the CNC kernelneeds for the corresponding operations.

– However if the execution time of the ControlReset is smaller than the preset interval timebetween two BCD-strobes (See Ä Chapter4.2.3 “BCD Processing” on page 165), thesignal is lengthened to this time to ensure asure recognition by the PLC program. This isone reason not to set the preset interval timebetween two BCD-strobes (machine param-eter: BCDDistanceTime) to a zero!

– This output will be reset to false as soon as anew cycle start occurs (See Ä Chapter 4.1.1.2“IN_START” on page 34), or a Control Reset isexecuted, or the operator selects another oper-ating mode than AUTO.

– If the request for the execution of CONTROLRESET prevails longer than the execution ofthe CONTROL RESET itself lasts, then if nec-essary CONTROL RESET is executed repeat-edly one after another, so that the signalON_RESET (CONTROL RESET) repeatedlychanges its value in such a case.



CAUTION!A "Control Reset" has following consequences:

– Active G-codes are reset to pre-defined values.For this definition refer to the machine param-eter GCodeAppl. Current active G-codesvalues can be read in the G-Code window ofthe operating mode "INFO" (refer to the PAOperating Manual).

– Program processing is interrupted and reset– All axes movements are interrupted

Control Reset Is Active



12.01.2017 | 150

4.2.1.10 ON_NO_CNTRThis signal tells the PLC if the position control loops are not closedon all axes.

CAUTION!When a position control loop is not closed in theCNC the corresponding axis may be moved awayfrom its last controlled position without any warningor any error detection!

Such movement can result e.g. from manual axisshifting.

By analog axes interface, it is very likely that theaxis will move away very slowly due to drift of thedrive and motor; this means that with a commandof 0V the motor is not really at zero speed!

Value Description

0 The position control loops are sup-posed closed

1 The position control loops are notclosed. The CNC is either in Emer-gency Stop state, or in the testoperation mode "Without Move-ments"

– Even if this signal is false, it is herewith notsure that all axes are in controlled positionloop, as single axis loops can be deactivated:See Ä Chapter 4.1.3 “CNC Input DWORD:IN_DRIVEON” on page 56

– If this signal is true, no servo error detectionwill be done. The axis position display just fol-lows the effective axis position!

– In analog axes interface, it is highly recom-mended to disable all motor drives when thissignal is true!

Position Loops



12.01.2017 | 151

4.2.1.11 ON_HOME_OKThis signal tells the PLC that the homing cycle has been done forall axes that have been defined with a mandatory homing.

Value Description

0 The mandatory homing cycle is notdone

1 The mandatory homing cycle isdone for all axes

– The definition whether an axis has to execute ahoming cycle or not is done by the machineparameter RefAxesAppl.

– On machines where no axis has to execute ahoming cycle, this signal will always be true!

– By machine where at least one axis has to exe-cute a homing cycle, as long as this cycle hasnot been executed to its end:– the signal ON_HOME_OK remains false– manual jog movement is forbidden– the selection of AUTO mode is forbidden

– By machine where at least one axis has to exe-cute a homing cycle, manual jog movementscan be requested by the operator by selecting"Hand Release" mode (refer to the PA Oper-ating Manual).

Homing Cycle



12.01.2017 | 152

4.2.1.12 ON_NCERRORThis signal tells the PLC that the CNC has recognized a criticalerror. Serious errors are states, which endanger the operationalsafety of the machine or prevent the further execution of activefunctions, or in general the processing of NC programs.

Value Description

0 No serious error state

1 At least one serious error has beenrecognized

The CNC recognizes three different classes of serious errors:

n Safety relevant, non-acknowledgeable errorsn Safety relevant, acknowledgeable errorsn Program execution errors which prevents further execution

Safety relevant, non acknowledgeable errors– These errors include, among others:

– hardware errors in the position measure-ment signals

– hardware errors in peripheral bus systems,including PAMIO components

– By such errors:– the safety relay "NC Ready" is opened– the Emergency Stop locking state is acti-

vated (See Ä Chapter 4.1.1.1 “INEMER-GENCn” on page 32)

– the signal ON_NCERROR becomes true– Error acknowledgment:

– only by close and re-start the PA 8000application

Safety relevant, acknowledgeable errors– These errors include, among others:

– servo-errors, e.g. an axis exceeds its max-imum following error

– By such errors:– the safety relay "NC Ready" is opened– the Emergency Stop locking state is acti-

vated (See Ä Chapter 4.1.1.1 “INEMER-GENCn” on page 32)

– the signal ON_NCERROR becomes true– Error acknowledgment:

– control reset

NC Is In Error



12.01.2017 | 153

Program execution errors which prevents fur-ther execution– These errors include, among others:

– syntax or checksum errors in the NC pro-gram

– geometric errors in the NC program– By such errors:

– the execution of the program is interrupted– the signal ON_NCERROR becomes true

– Error acknowledgment:– control reset– program correction

4.2.2.1 CNC StatusThe following signals are giving information to the PLC aboutactive CNC statuses.

Value Description

0 The status is not active

1 The status is active

DWORD Meaning

ON_ STAND Presently all axes are at a stillstand. There is nomachine movement.

ON_ RAPID A rapid traverse movement (G00) is being executed.

ON_ THREAD A thread cutting (G33/G34) cycle is being executed.

ON_HOMEOK A programmed homing cycle (G74) is being exe-cuted.

ON_READ_TO_BLK The "Read to Block" function is selected by theoperator.

ON_TRANSF The program is interrupted: no further block can beprocessed.

ON_CYCLE_STOP The CNC is in the cycle stop lock status.

ON_G04_ACTIVE A programmed dwell time (G04) is pending.

ON_STANDPossible cause for ON_STAND = 1 (True)– A block is in execution in any AUTO mode, in

which no interpolation is programmed

OR– The CNC is in AUTO mode and the signal

IN_ENABLE is 0 (False) (See Ä Chapter4.1.1.5 “IN_ENABLE” on page 41)

OR– The CNC is in MAN mode or in the Homing

cycle and the signal IN_DRENxx of the axis tobe moved is 0 (False) (See Ä Chapter 4.1.4.1“IN_DRENxx” on page 61)

OR– The feed override is set to 0

OR» Continued on the next page

CNC Status



12.01.2017 | 159

– The CNC is in Feed Hold lock status

OR– The CNC is in Emergency Stop status (SeeÄ Chapter 4.2.1.6 “ON_EMERG” on page 147)

ON_RAPID– Rapid traverse is usually set (unless otherwise

specified) as default value in the first G-codegroup (G00/01/02/03/07/12/13/33/34)

– The ON_RAPID signal will be output onlyduring an active rapid movement!

– A rapid movement is possible only in AUTOmode (sequential, single block or MDI) and thisoutput will only be set if one of these modes isactive

– The rapid traverse signal is set as well by G00blocks when the CNC is in the operating testmode "Without Movements"

– In the operating test mode "G01 Override",even if G01 blocks are then executed in rapidtraverse speed, the signal ON_RAPID will onlybe set by blocks programmed with G00 code

ON_THREAD– If the machine is executing thread cuts, it is

very important to monitor this signal as it will benecessary to use special ways of achievingimmediate movement stops. Refer especiallyto the notes by "IN_STOPn" (see Ä Chapter4.1.1.3 “IN_STOPn (Inverted)” on page 37),"IN_TRANSF" (see Ä Chapter 4.1.1.4“IN_TRANSF” on page 39) and "IN_ENABLE"(see Ä Chapter 4.1.1.5 “IN_ENABLE”on page 41)

– In the operating test mode "Without Move-ments", NC blocks with thread cuts (G33/G34)are skipped, and therefore the ON_THREADoutput will not be set

ON_HOMEOK– Within program code, it is possible using the

G74 instruction to start the homing cycle of oneor several axes (refer to the PA ProgrammingManual). This output is set as soon as at leastone axis has been programmed for a homing



12.01.2017 | 160

CAUTION!Even with almost the same name, this output dif-fers from "ON_HOME_OK" (see Ä Chapter4.2.1.11 “ON_HOME_OK” on page 152)! Makesure not to mix them up!

ON_READ_TO_BLK– The "Read to Block" function can be selected

(using the standard PA HMI) with:– AUTO / Program selection / Block selec-

tion / Read to blockWhen a block is selected with this function, theprogram will be processed until this block, allpreparatory functions being executed, all BCDcodes being output, but without axis move-ments

– The PLC should use this signal to determine ifauxiliary (BCD) codes must be executed or notby the machine under these circumstances

ON_TRANSF– The PLC can interrupt program processing

using the signal "IN_TRANSF" (see Ä Chapter4.1.1.4 “IN_TRANSF” on page 39). Howeverwhen this input is set true, the program pro-cessing might not be interrupted immediately:the movement commanded in the active block(even over several blocks by active look-ahead) will continue till end of the block (unless"IN_ENABLE" is set false at the same time as"IN_TRANSF"). The output "ON_TRANSF" willbe set only when all these jobs have been fin-ished

– The ON_TRANSF output will be set 0 (false)when "IN_TRANSF" has been set 1 (true)again and after the next incoming "IN_START"!

– During backward program execution ((SeeÄ Chapter 4.2.1.13 “CNC Status”on page 155), if the backward buffer is reached(machine stop), the output ON_TRANSF willbe set 0 (false). For safety reasons, after"IN_START", ON_TRANSF changes to 1 (true)or 0 (false) depending on "IN_TRANSF" bitvalue



12.01.2017 | 161

ON_CYCLE_STOP– The ON_CYCLE_STOP output becomes 1

(true) as soon as "IN_STOPn" (See Ä Chapter4.1.1.3 “IN_STOPn (Inverted)” on page 37)changes from true to false, and stays true aslong as this input is false

– The ON_ CYCLE_STOP output will be set 0(false) when "IN_STOPn" has been set 1 (true)again and after the next incoming "IN_START"!

ON_G04_ACTIVE– The ON_G04_ACTIVE output becomes 1

(true) for the duration of a programmed dwelltime in a part program

– Dwell times are programmed with the nonmodal instruction: G04 Fxxxx where the Fvalues defines the time either in seconds or inmilliseconds depending on the machine param-eter setting. The relative machine parameter isFactorG04inMs, in the group NCAddress-Format

4.2.2.2 EDM functions (option)The DWORDs ON_INTVEND, ON_INTRET and ON_INTVHLD arerelated to the optional function:

n EDM – Discharge Machinen Refer to the PA Software Function Manual for detailed infor-

mation.

4.2.2.4 CNC error: handwheel tick lostWith these outputs, the CNC tells to the PLC that ticks read in fromthe handwheel(s) will not be executed because of excessive lag.

If the factor of the handwheel is selected big, it is easy to commandgreat velocities. In handwheel mode the lag of the handwheel islimited to make sure that the axis will be able to stop in a reason-able time when the hand wheel is stopped. The limit is automati-cally set to such a value that the axis will stop not later than thepredefined slope time (machine parameter AxisSlopeTime)+ 100ms.

DWORD Meaning

ON_HDW_TICKS_LOST3 Ticks lost on handwheel input#1



Value Description

0 All ticks of the handwheel will bedone

1 Handwheel limit has been reached.The exact number of handwheelticks will not be driven.

When a handwheel is in a situation of limit, the cor-responding output is not set true permanently. TheCNC gives this output as a strobe with the sameduration as the one defined by the machine param-eter BCDStrobeTime (see Ä Chapter 4.2.3 “BCDProcessing” on page 165).

Handwheel Tick Lost



12.01.2017 | 163

4.2.2.5 ON_PLC_MOV_NO_OVRThis output is a simple acknowledgment of the command"IN_PLC_MOV_NO_OVR". When set, it means the feed overrideis not active during a movement done with the PLC functionMove_Interpolating_Axis (see Ä Chapter 4.1.16 “CNC InputDWORD: IN_IPOMVMT” on page 91).

Value Description

0 Override active by PLC positioningcommands

4.2.3 BCD ProcessingAuxiliary codes are additional information written in a NC programthat allow the programmer to synchronize machine events (likecoolant on/off, Chip conveyor on/off, etc…) with the program exe-cution. This happens when a defined letter with its decimal value isprogrammed in a NC block. Auxiliary codes are called BCD codesas the CNC kernel transmits this information to the PLC in a codedway: Binary Coded Decimal.

Basically, the PA CNC allows up to 4 different BCD codes. Bymachine settings, the letter(s) used for these BCD codes can bechosen freely. Usually, the most common choice is for M, S, and T,no standard being defined for the fourth BCD code.

It is possible herewith to program up to 4 different auxiliary func-tions in a single block, using the 4 predefined different letters.

In the PLC-CNC signal interface, there are two D-WORDS (64 bits)available to send the value of the programmed code to the PLC.This range allows the programming of BCD codes from up to 16digits! The value of any of the 4 different BCD codes is sent on thesame D-WORDS. In order to determine to which letter the presentvalue corresponds, and to mark whether the value is valid, theCNC gives to the PLC 4 different strobe signals.

When several auxiliary codes are programmed in the same NCblock, the following timing is preset in the CNC for BCD code trans-mission to the PLC.

Fig. 2: Timing values

The timing values shown in Fig. 2 are defined by machine parame-ters (see Ä Table on page 166):

CAUTION!BCD Character DefinitionThe (up to) four alphabetic characters necessaryfor BCD codes are defined by the means of themachine parameter of the group NCAddress-Format.Should a character be used to define a BCD code(e.g. M), the index #5 of CharacterApplTabMmust be set to a hex value of 8000, where the 8(MSB =1) selects this letter as a BCD code and thelow byte value (here 0) gives the index of the pri-ority of this BCD code:

– index=0 = highest priority = first BCD code– index=3 = lowest priority = fourth BCD code

The letter M being defined as first BCD code, thePLC will recognize an M-code by checking the firstBCD strobe and the corresponding BCD value.

4.2.3.1 BCD StrobesThe CNC sends these signals as pulse (strobe) when the corre-sponding auxiliary code letter is programmed in the active block.The value of the programmed code has to be read from "ONBCD-WORD1" and "ONBCDWORD2" (see Ä Chapter 4.2.3.2 “CNCOutput DWORD: ONBCDWORD1” on page 169 and Ä Chapter4.2.3.3 “CNC Output DWORD: ONBCDWORD2” on page 170).

CAUTION!BCD Code FunctionsThe functions driven by the individual BCD codesdepend on the respective PLC program. Indeedsome BCD codes, mainly M-codes, are alsodirectly processed by the CNC. Further informationabout this can be found in the PA programmingmanual and in the machine manufacturer's docu-mentation.

In a single NC block all 4 BCD letters can be pro-grammed, but each BCD letter however only once.

DWORD Meaning

ON_STROBE1 The BCD value is valid for thefirst BCD code

ON_STROBE2 The BCD value is valid for thesecond BCD code

ON_STROBE3 The BCD value is valid for thethird BCD code

ON_STROBE4 The BCD value is valid for thefourth BCD code

Value Description

0 The BCD value is not valid for thiscode

1 The BCD value is valid for this code

– Only one of these four signals can be 1 (true)at a time, the three others are 0 (false)


ON_STROBEx

– The strobe duration is defined by four machineparameters: BCDStrobeTime[1-4]. To guar-antee a sure recognition of the BCD-codes bythe PLC, each individual time must be adjustedto be larger than the tact time of the PLC pro-gram!

– For each of the 4 BCD's it can be preset, thatan interpolation programmed in the same NCblock will be executed only after the delivery ofthe BCD's to the PLC: the CNC generates aninternal "Interpolation Stop". (See machineparameter: BCDStrobeTime[1 - 4])In the above example (See Fig. 2), if thisinternal interpolation stop is applied for thesecond BCD code, a movement possibly pro-grammed in the same block would start onlyafter the second BCD value has been deliv-ered, in this case at the half of T5.

– If machine functions are activated via BCD-codes, whose execution times are longer thanthe output time of the BCD's, and if the furtherprocessing of the NC program is to be inter-rupted during the machine function, this can becontrolled with the signal "IN_TRANSF" (SeeÄ Chapter 4.1.1.4 “IN_TRANSF” on page 39)

– If machine functions are activated via BCD-codes, whose execution times are longer thanthe output time of the BCD's, and if an interpo-lation programmed in the same block is to behalted during the machine function, this can becontrolled with the signal "IN_ENABLE" (SeeÄ Chapter 4.1.1.5 “IN_ENABLE” on page 41)

– To ensure that two identical BCD-codes suc-cessively programmed in two consecutiveblocks are also recognized twice by the PLC,the strobe signals must be evaluated on theirrising flange (transition from 0 to 1)

– The BCD strobe signals are output as well inthe test mode "Without Movements"

The "Binary Coded Decimal" code allows representation of dec-imal values from 0 to 9 on 4 binary bits. Each of the aboveDWORDS have to be regarded as 8 groups each of 4 bits:

1st group: ON_BCD1 - ON_BCD4

2nd group: ON_BCD5 - ON_BCD8

3rd group: ON_BCD9 - ON_BCD12

4th group: ON_BCD13 - ON_BCD16













Group value Meaning

0000 Decimal value: 0










Other values Not used



12.01.2017 | 171

As example, for a programmed code = 23456789, the PLC mustread "ONBCDWORD1" like this ( Ä Table on page 172):

Group BCDcode

ONBCDWORD1 Decimalvalue

Fullvalue

1 1001 ON_BCD1 – 4 9

23456789

2 1000 ON_BCD5 – 8 8

3 0111 ON_BCD9 – 12 7

4 0110 ON_BCD13 – 16 6

5 0101 ON_BCD17 – 20 5

6 0100 ON_BCD21 – 24 4

7 0011 ON_BCD25 – 28 3

8 0100 ON_BCD29 – 32 2

– The value of ONBCDWORD1 and of ONBCD-WORD2 should be only evaluated if the corre-sponding strobe signal (see Ä Chapter 4.2.3.1“BCD Strobes” on page 167) has a value 1(true)

– Usually a definition of auxiliary codes on 8digits is from far enough! In such a case, theevaluation of ONBCDWORD2 will not be nec-essary. The number of digits applied for eachBCD letter can be found in the machine param-eters of the group NCAddressFormat, withindexes 1 and 2 of the corresponding Charac-terApplTab(x)

– After completion of BCD code transfer, the lastvalue of BCD code will be kept until the nextBCD code

– The BCD value signals are output as well inthe test mode "Without Movements".

Value Description

0 The axis is not In Position

1 The axis is In Position

– When an axis position loop is closed (therefore"INEMERGENCn" and the corresponding bit of"IN_DRIVEON" must both be "1 (true)"), it canbe "In Position" only if it is presently not inter-polating and if its lag error is smaller than theadjustable "In position" window.An axis is considered as being interpolated aslong as the programmed movement is not fin-ished, even if there is an active cycle stop("ON_CYCLE_STOP" = 1 (true)) or if themovements are interrupted ("IN_ENABLE" = 0(false)) or if the feed rate override is set to "0"!An axis interpolation will be finished as welleither by Control Reset, or by a change ofoperating mode, or by a rising edge of the cor-responding bit of "IN_DRIVEON".

– In emergency stop locking situation("ON_EMERG" is 0 (false)), an axis will be "InPosition" only if its lag error is smaller than theadjustable "In position" window.

– When an axis position loop is not closed (thecorresponding bit of "IN_DRIVEON" is 0(false)), it will be always "In Position".

– The "In Position" window size is defined bythe machine parameters InpositioningArea.

– The ON_INPxx outputs might be used as anexample for the command of axis clampingwhen such devices are necessary.

5 PLC / CNC - Data InterfaceThe CNC-PLC data interface is designed for the transmission ofdata values.

There is no data structure organization, and each of the data trans-ferred over this interface has its own data format. When usingvalues out of this data interface, the PLC developer must take spe-cial care of the format of each of these data.

CAUTION!For historical reasons some BOOLEAN values(BOOL) are set up over this data interface.

CAUTION!Some of the data interface values are read-only! and some others are write-only!It will be specially marked therefore. If not men-tioned as read- or write-only, the data can either beread or written from the PLC.

CAUTION!Some of these data interface values arereserved for PA internal use!They must not be used in the PLC program! There-fore, even if this kind of variable can be found asdefined in the "systemvars.cfg" file, they will notappear in the present manual. The list of thesereserved data can be found under chapter "Ä Chapter 6 “List of variables reserved for PA'sinternal use” on page 263".

5.1 General data values5.1.1 Shut-down control and commandsUnder the top menu "System", there are two ways for the operatorto close the Power Automation CNC:

n Softkey 8: "Exit" - This closes the PA CNC software, the PCremaining still active.

n Softkey 7: "Shutdown OS" - This closes as well the PA CNCsoftware but initiates also the Windows Operating System shut-down

The PLC can either delay or deny both shutdowns.

The PLC can initiate himself both shutdowns.

SET_AXPOS_VALUENew position definition for aset position command

Write-Only!

Format LREAL

Unit The value of the position has tobe defined in internal incre-ments!

The Set Axis Position command will be executedby the CNC only if the bit of "IN_DRIVON" (SeeÄ Chapter 4.1.3 “CNC Input DWORD:IN_DRIVEON” on page 56) corresponding to theaxis whose position has to be set, is set to 0(false).

5.1.8 Program break pointsWhen debugging a NC part program, it might be interesting to usestep by step mode. Therefore one can use either the AUTO SingleBlock mode and/or the Interpreter Single Step mode (the last oneespecially by cycle programming - See Ä Chapter 4.1.27.2“IN_SINGLE STEP” on page 111).

Using these test modes from the program beginning might beunnecessary and might take a lot of time. That's why the PLC getsthe possibility to set up to 4 breakpoints.

Each breakpoint has to be set by the definition of its part programnumber and by its block number.

When such a breakpoint is reached, the interpreter single stepmode is turned on, and the NC block with breakpoint remainsactive until the next "IN_IPR_DO_STEP" (See Ä Chapter 4.1.27.3“IN_IPR_DO_STEP” on page 112).
