Lithium Battery Replacement

The internal lithium battery is a technician replaceable item.

Caution: the lithium battery used in this device may present a fire or chemical burn hazard if mistreated. Do not recharge, disassemble, heat above 100°C (212°F) or incinerate. Replace battery with Panasonic, Part No. BR-2/3A or Micro-Comm Part No. BAT-004-3 only. Use of another battery may present a risk of fire or explosion.

To replace the battery, remove all power to the unit. Caution – power to the relay contacts may be sup-plied from other equipment. Un-plug all of the terminal blocks and communications cables. Un-mount the unit and remove the four screws on the sides of the unit. Place the unit on a clean working surface and lift the mounting base from the face plate. The battery is located in the center of the face plate, clipped into the battery holder labeled J15. Use a small blade screwdriver to pry the battery clip to the side and up. Then pry on the other side to fully remove the battery clip. At this point the battery is held in place by the battery holder contact spring force and it is simple to remove the battery with your fingers. Place a new battery in the battery holder, matching the orientation of the “+” and “-“ markings on the battery to the battery holder. Replace the battery clip by pressing it into place. Mate the mounting base to the face plate and re-install the four screws. Re-mount the unit and plug all of the cables back into the unit.

Dispose of the battery properly. Keep away from children. Do not disassemble and do not dispose of in fire.

Expansion I/O Module Setup

Dip switches set both the address of the module and the baud rate used by the RS-485 connection to the RTU.

The EDI16, EDO16, EAI8 and EAO4 modules allow an RTU to have additional discrete or analog inputs/outputs. These modules are connected to the RTU using the COM3 RS-485 port on the M1550.

I/O Module

Switches 1-7 set the address (binary):Module #1 = switches 1-7 OFFModule #2 = switch 1 ON, 2-7 OFFModule #3 = switch 2 ON, 1,3-7 OFFetc.

The baud rate is set using switch 8:9600 baud = switch 8 off19200 baud = switch 8 on

The default baud rate used by the RTU is 9600 baud. This can be changed in the RTU Configuration 32 program if necessary. The normal COM3 Mirco-Comm I/O polling loop will take around 2.6 seconds to update all modules at 9600 or around 0.7 seconds at 19200 baud. Micro-Comm I/O protocol on COM3 currently supports (4) EDI16, (4) EDO16, (4) EAO4 and (2) EAI8 modules.

All modules use Modbus RTU protocol and will be communicated with automatically using the “Micro-Comm I/O” protocol or can be communicated with manually using the MESSAGE() or MIOMSG() functions in script.

Display Module Operation

The Micro-Comm display module allows the operator to view up to 32 analog levels, 32 discrete input conditions, 32 discrete output conditions, change up to 32 stop/start setpoints, change all 8 output timer settings (both on and off delays) , view/change the user variables (X1-X32) and view/change user memory with up to 64 screens. In addition to these options there is a debug mode available that will let the operator turn on and off outputs, check inputs and view communications.

General Instructions:• Use the Up/Down arrows to move between categories (analog level displays, discrete inputs and

outputs, timer settings, stop/start setpoints, user variables and user memory screens)• Use the Right/Left arrows to move between items (which analog screen, timer output etc.)• Press ENTER to start entering a value for timers or setpoints.• Use the number keys to enter values. Use BKSP if you need to backspace.• Press ENTER when done with each entry.

Special Modes:• Type .123 to get into the debug mode. Then hit the ENTER key to see a menu of choices.• Type .456 to get into the view communications screen. All radio communication data will then appear

on the display. Press the up arrow to get out of this mode.• Type .741 to temporarily go from CTU32 mode to display mode. Note: This will only work if

“hankshake” is disabled ahead of time since the RTS line will normally be off - see setup below.

NOTE: The display communicates with the RTU using a serial cable (9 pin to RJ-11). The protocol options should be set to 9600 baud, 8 data bits, none parity, echo disabled. These are the factory defaults. To set a display back to factory defaults, hold down the PERIOD, ZERO and F1 keys during power up and then press the F1 key to load the defaults. The default for “handshake” is “enabled” (this will need to be disabled if you plan to use the temporary display mode described above).

To change these parameters, press the PERIOD, ZERO and F1 keys any time after power up.

Program Installation

RTU Configuration 32 is required for programming the M1550 PLC.

RTU Configuration 32 is currently available for Windows NT/2000/XP and Mac OS X.

To Install the Windows version, follow the steps below:

When upgrading to a new version of the program, go to the Control Panels in Windows and double-click on Add/Remove Programs. Look through the list and remove any old versions of RTU Configuration.

1) Insert the CD into the CD-ROM Drive.2) RUN the SETUP program located on the CD-ROM.3) Follow the prompts and do a typical install.4) After installation, the program icon will appear in the Start menu’s Program list.

When running the configuration program for the first time you will need to look at the serial port setup screen to make sure you have the correct COM port number selected. The port setup is located in the program’s “Edit - Preferences...” menu. Connection to the RTU is by means of a Null-modem cable from the computer’s RS-232 port to the RTU’s COM2 port (display port).

RTU Information Screen

The RTU Information screen contains version, date, checksums, user information, address switch settings as well as a picture of the RTU. This information about the RTU will be available after the user has read the Personality Module. The Job Name and Site Name fields can be changed if necessary and the User Name and Last Programmed will reflect who made the most recent change. All the “User” information is sent to the RTU whenever the personality data is uploaded.

- 22 -

Configuration Parameters

The screen below shows a sample RTU Configuration dialog box. This screen is where all the operational parameters stored in the Personality Module can be changed (radio communications parameters, output timer settings, automote control settings and stop/start setpoints).

To retrieve the personality data from an RTU, click on the blue down arrow icon or select Read Personality Data from the Transfer menu. After making changes, click the blue up arrow icon or select Program Personality Data from the Transfer menu.

- 23 -

RTU Configuration Parameters

Model Number The model of the RTU being configured is selected and shown here.

Protocol The protocol selection for the radio communications port (COM1). Options include Micro-Comm RTU32, DF1 Half-Duplex Slave, DF1 Half-Duplex Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave, Modbus RTU Master or Modbus/TCP.

Baud Rate This selects the speed for the radio communications port (COM1). 110, 300, 600, 1200, 2400, 4800,

9600, 19200, 38400, 57600 and 115200 bps are supported.

Parity Parity checking mode (Even, Odd or None). Even parity should normally be selected when using Micro-Comm RTU protocol.

Data Bits The number of data bits used by the radio port (5, 6, 7 or 8). This should normally be set to 7 for Micro-Comm RTU communications.

Stop Bits The number of stop bits used by the radio port (1 or 2). This should normally be set to 2 for Micro-Comm RTU communications.

PTT Time in milliseconds that will occur after the radio is keyed and before the data is sent out the radio port. This should normally be set to 250 msec or more for Micro-Comm RTU communications using conven-tional radios. Data radios will allow for much lower PTT times (50 msec or less).

Enable Modem When this option is checked, the M1550 will turn on the internal 600 (or 110) baud radio modem. Leave this box un-checked when using an external radio modem.

Ant. Outputs The range of 8 discrete outputs to use when a remote is doing Antenna/Radio switching. RTU32 proto-col can only specify an 8 bit mask so this selection allows it to be applied to outputs 1-8 or 9-16.

Ant. Default Discrete ouput number to leave on for Radio #1 when doing Antenna/Radio switching at a remote.

Station # For use with Modbus or DF1 protocols ONLY. This sets the station # for this RTU as used by the proto-col on all of the communication ports.

COM2 Protocol Communication protocol used on COM2. This can be Micro-Comm Display, Micro-Comm RTU32, Micro-Comm CTU32, DF1 Half-Duplex Slave or Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave or Master, Modbus/TCP, Web Server, EtherNet/IP SLC and EtherNet/IP CLX (compact logix).

COM2 Baud This selects the speed for the COM2 port. The default is 9600 baud for compatibility with the Micro-Comm Display Module.

COM2 PTT Time in msecs that will pass after RTS is turned on and before data is sent out COM2. The default is 0 which will leave the RTS turned on all the time.

COM3 Protocol Communication protocol used on COM3. This can be Micro-Comm I/O, DF1 Half-Duplex Slave or Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave or Master, Modbus/TCP, Micro-Comm Display, Micro-Comm RTU32, CTU32, EtherNet/IP SLC and EtherNet/IP CLX (compact logix).

COM3 Baud Communications speed for the Micro-Comm I/O modules or for Modbus RTU / DF1 communication. The default is 9600 baud.

- 24 -

Timer SettingsThe timer settings control how long the RTU will wait to energize or de-energize a relay output when it has been told to come on or go off. These timers will always be used regardless of the mode of operation - Micro-Comm CTU control, Script Lan-guage, Modbus or DF1.

Stop/Start Setpoints 1-32These setpoints can be labeled and accessed from the Micro-Comm Display module and then used in script for control.Stop and Start setpoints are scaled using the analog selected in the Stop/Start Labels screen.

Use 8-bit Remote SetpointsThis option will force the remote setpoint protocol (used by SCADAview) to use 8-bit (LSB) values. This may be required if the central is a C2000 or earlier.

Pulse Dividers These sets the number of pulses that must occur before the pulse input counter is incremented. Normally this will be set to 1.

COM4 Settings The options for COM4 are similar to that of COM1 with the additional “Mode” option.

- 25 -

Ethernet (COM5) Settings The options for the ethernet port are configured with the screen shown below:

Protocol The protocol selection for the Ethernet Port (COM5). Options include Micro-Comm RTU32, DF1 Half-Duplex Slave, DF1 Half-Duplex Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave, Modbus RTU Master, Modbus/TCP, Micro-Comm CTU32, Web Server, EtherNet/IP SLC and EtherNet/IP CLX (compact logix).

Mode This selects whether COM5 will be a TCP Server, TCP Client or UDP Mode (client/server).

IP Address TCP/IP Address of the M1550 PLC on the network.

Subnet Mask Selects the class of the local network (usually either 255.255.255.0 or 255.255.0.0)

Gateway The address of the local network router (if any).

Reverse-Poll Enabling reverse-poll when using CTU32 protocol will allow multiple computers (up to 4 using client mode) to receive status updates.

Local TCP Port Port number used when we are a TCP Server. Our default is 4001. It will be forced to 44818 when using EtherNet/IP. It should also be changed to 502 when using Modbus/TCP protocol.

Max. Connect The maximum number of clients that can connect to us when we are a TCP Server (1 - 4).

Destination IPs If the mode is a TCP Client, these are the addresses and port numbers that the PLC will connect to.

Local Listen Port Port number on which we will receive data from the other PLCs when using UDP Mode. This can be the same port as used for transmitting data. (4001 is our default).

UDP Ranges When using UDP Mode, these ranges of IP addresses and port numbers will all be sent data when the PLC transmits. Note: Do not include the PLC’s own IP Address in these ranges.

The “Network Search” button will scan the local network for our PLCs.

- 26 -

Analog Labels and Scaling Factors

To change analog labels and scaling factors, click on the blue water tower icon or select Analog Labels & Scales from the View menu. The labels and scales are retrieved/sent to the RTU during reading/writing of the personality module configuation data.

Up to 32 analog levels can be displayed and they will always appear in the order entered in the setup screen. If an analog label is left blank it will not show up on the display.

When analog levels are displayed, the offset is first added to the raw analog value and the result is then multiplied by the range value. (This matches the Micro-Comm SCADAview program). A Range/Preset calculator (shown below) can be displayed by right-clicking and selecting the menu option.

- 27 -

Output Timer Labels

To change the 20 character output timer display labels, click on the clock icon or select Timer Labels from the View menu. The labels are retrieved/sent to the RTU during reading/writing of the configuration data. These labels are normally used for pumps and provide both ON and OFF delays entered on the Micro-Comm Display Module.

Note: Lines where the label is left blank will not be accessible from the Display Module.

- 28 -

Stop/Start Setpoint Labels

Stop/Start labels are used on the Display Module to allow the operator to change operational parameters such as Pump Stop/Start setpoints, High/Low alarms and Pump Restore/Cutoffs. Along with the 20 character label is a selection for what type of setpoint (Stop/Start, High/Low etc.) and which analog input # will be used for scaling and units.

Note: Lines where the label is left blank will not be accessible from the Display Module.

- 29 -

X Variable Labels

User variables are the 16-bit unsigned integer X1-X32 script language variables that can be used for any purpose. By entering a label in the User Variable Labels setup screen, the current value will be shown and can be changed on the Display Module.

- 30 -

Discrete I/O Labels

Labels for both 32 discrete inputs and 32 discrete outputs are user defined in the RTU Configuration 32 software. These labels may be used to display pump calls, pump runs, valve positions, alarms etc. A 12-character label is used to name the input or output along with a 6-character ON label and a 6-character OFF label to describe the on or off state. If the input or output name is left blank it will not appear on the display and if no discretes are labeled the display will just skip over the entire section (inputs or outputs).

The screen below shows the Discrete Input Labels setup screen:

- 31 -

User Memory Screens

User memory screens allow for display and entry of data stored in user memory (locations 0-15999 in the M1550). The raw data type can be either 16 bit or 32 bit (using 2 consecutive user memory locations) and can be displayed as numeric, discrete labels or binary numbers.

The user memory screens are accessed by arrowing all the way down to the bottom row of the Micro-Comm display.

The sample screens below show how a 32bit flow total could be displayed and how a pump HOA selector could be configured.

- 32 -

User Memory Database Editor

The User Memory Database screen provides the capability of reading, programming and editing all user memory locations (0-15999) as well as saving and loading a comma seperated (.CSV) database file. This file could then be used for data logging/trending or saving a backup copy of important data such as flow totals, runtimes etc. The screen shown below is accessed from either the Utilities menu or by selecting “Read User Memory” from the Transfer menu.

Right-clicking on this screen will bring up a menu with options to “Read User Memory”, “Program User Memory”, “Save CSV File...” and “Load CSV File...”. Double-clicking on a cell will put it into edit mode and a new integer value can be entered. The data will be displayed and entered in decimal unless the “Display User Memory and X Variables in Hex” is selected in the preferences.

This screen can also be made to show “live” data like the user memory data table viewer by selecting the “Auto-Refresh User Memory Database Window” option in the application preferences.

NVRAM DatabaseIn addition to the User Memory Database, there is also a very similar NVRAM Database window which can be used to download and save data from the RTU’s personality module. This could be used for long-term data logging since it currently supports 65000 words of data. The script commands NVREAD, NVWRITE and NVCOPY are used to manage this data.

- 33 -

RTU Script Language Editor

To enter or edit the Script Language Code, click on the script icon or select “Script Editor” from the View menu.

Script language can be retrieved from the RTU by clicking the Read button shown at the bottom of the editor window or by selecting Read RTU Script from the Transfer menu.

Lines starting with a single quote character are comments and do not get sent to the RTU when programming. Comments are saved in the .S5C configuration file and can optionally be saved to the RTU in place of the revision notes.

After entering lines of code the user can click the Check button to make sure the syntax looks ok and to see how many bytes of code have been used. Currently the main script code can’t be larger than 16894 bytes.

The code is then programmed into the RTU personality module by clicking the Program button or by selecting Program RTU Script in the Transfer menu.

Script subroutines are edited by selecting the subroutine number from the list in the lower-left corner of the screen. Each subroutine can be read, programmed and checked separately using this editor. Currently each subroutine can be up to 2110 bytes.

- 34 -

Revision Notes Editor

To enter or edit the Revision Notes for the RTU, click on the notepad icon or select Revision Notes from the View menu. The screen below shows some sample notes - they can be script comments, software description, revision history, variable tables or anything else desired.

The Read and Program buttons are used to retreive or store the notes in the personality module. Revision notes are also saved in the .S5C configuration file.

If the option “Use Commented Script for Revision Notes” is turned on in the preferences, this screen will be filled in with the current commented script whenever it is opened. It can then be programmed into the personality module in addition to the un-commented (compiled) script. The user will also then be asked if the commented script should be programmed whenever the configuration or compiled script is programmed. Commented scripts can be read back from an RTU and imported into the actual script by right-clicking and selecting the “Import Commented Script” menu option (shown below).

- 35 -

Data Table Viewer

The Data Table Viewer screen allows the operator to see and change I/O variables, User variables and the Stop/Start setpoints in real-time when connected to an RTU. This screen can be very useful when debugging script language code. The User Memory data table can display all user memory (a range of 64 locations at a time) and will allow for changing these values.

Analog inputs and Stop/Start setpoints are displayed as raw 12-bit numbers (0-4095) or can optionally be scaled based on the range/offset values entered in the analog setup screen. Pressing the “S” key on this display will toggle scaling on and off. Discrete inputs and outputs are shown as either 1 or 0 (on or off).

When the “Force I/O” option is selected, the I/O variables shown in red may be changed to the desired value by clicking on the readout box, typing a new value and pressing enter. When the “Disable Script” option is also checked, the script will stop running and any I/O that it was controlling will then be accessible.

- 36 -

Display Module Emulator

The display module is an optional hardware component to a M1550 PLC which allows an operator to see levels and change setpoints. When programming the M1550 with the RTU Configuration 32 software the operator can use the Display Module Emulator screen to see what the display module would show. This can be very useful since both the display module and the programming software may be using the same com port on the RTU.

- 37 -

Debug Terminal

The Debug Terminal screen allows the user to interact directly with the RTU over the programming port (COM2 or COM3) or with other third-party serial equipment. It will display incoming data using ASCII, Modbus or DF1 mode based on the “Display Mode” selection in the lower-left hand corner of the screen. Protocol analysis of master messages (requests) can be done by selecting “RTU32-Decode”, “Modbus-Decode” or “DF1-Decode”.

Data logging can also be done by clicking on the “Log Data...” button and typing in a file name.

Radio communications on COM1 can be monitored on COM2 - COM5 by clicking on the “COM1” button, COM2 can be monitored on COM3-COM5 by clicking the “COM2” button etc,etc.

The “Debug” button will enter a hardware debugging mode where outputs can be turned on and off, inputs can be read, the clock can be set etc. Press the Enter key when in this mode to get a menu.

Functions:

AFAIL(af#, rawvalue, lowlevel, flsecs, ftcsecs) Returns an analog sensor fail condition alarm based these parameters: af# - a unique analog fail function number (1-64) rawvalue - the current analog value passed-in prior to scaling lowlevel - the level at which a sensor-fail condition will be triggered flsecs - number of seconds before a fail-low will occur ftcsecs - number of seconds before a fail-to-change will occur Note: The function will return a “1” for fail-low, a “2” for fail-to-change and “3” if both of these conditions exist. Using a zero value for flsecs or ftcsecs will disable that type of alarm. Example: X1=AFAIL(1, AI1, 818, 10, 0) ‘returns a “1” if analog input is below 819 for 10 secs

AHIGH(ah#, alevel, highlevel, restore, failsecs, restsecs) Returns a “1” when there is an analog “high” condition given these parameters: ah# - a unique analog-high function number (1-64) alevel - the current analog level to be tested highlevel - setpoint at which the high-level should occur (after nsecs) restore - setpoint at which the high-level will clear (after nsecs) failsecs - # of seconds the level needs to be at or above the high level before alarming restsecs - # of seconds the level needs to be at or below the restore setpoint before the alarm clears Note: Setting both the highlevel and restore setpoints to zero will clear and disable the alarm.

AIN(ai# [,nsamples [,stime [,value]]]) Returns the value for a given analog input number given these parameters: ai# - analog input # (1-64) nsamples - optional number of samples to average (1-64 or 0 for no averaging) stime - optional time between the samples used in the average (in seconds) If stime is not given or is set to zero, the sample time will be approximately 250msec. value - optional value to set the analog input to, ignoring the other parameters Example: AI2=AIN(1,8,4) ‘averages the last 8 values for AI1, sampled every 4 seconds

AITOPI(ai#, pi#, 420flag) Sets the parameters for the real-time (background task) analog-to-pulse converter. Setting the ai# to 0

will disable the converter for the given pi#. The 420flag parameter tells the converter to use 4-20ma (819-4095) or 0-5volts (0-4095) for the input range. The pulse counter is incremented at a rate of 0 to 64 pulses per second based on the most recent analog input sample value.

ai# - analog input # (1 - 64) pi# - pulse input # (1 - 64) 420flag - analog scale (0=0-5volt, 1=4-20ma) Example: AITOPI(3,1,1) ‘converts a 4-20ma signal on AI3 to a pulse of 0-64pps on PI1

ALOW(al#, alevel, lowlevel, restore, failsecs, restsecs) Returns a “1” when there is an analog “low” condition given these parameters: al# - a unique analog-low function number (1-64) alevel - the current analog level to be tested lowlevel - setpoint at which the low-level should occur (after nsecs) restore - setpoint at which the low-level will clear (after nsecs) failsecs - # of seconds the level needs to be at or below the low level before alarming restsecs - # of seconds the level needs to be at or above the restore setpoint before the alarm clears Note: Setting both the lowlevel and restore setpoints to zero will clear and disable the alarm.

AOUT(ao# [,value]) Writes the the given value to the analog output #. Also returns the value of the given analog output #. If the value parameter is not given, it just returns the current value.

BMSK([b0,...b15]) Returns an unsigned integer value with bits set as given in the parameters. This can be useful when creating and passing pump enable bit masks to the GROUP() function.

Example: X9=BMSK(X1,X2,X3,X4) This would set X9 equal to “15” if X1,X2,X3 and X4 are all equal to “1”.

BSET(mloc, bnum, bval) Sets a bit in memory referenced with mloc to a given value (0 or 1). A memory location in the RTU will correspond to it’s Modbus reference location shown in DF1-Modbus table minus 40000. Supported memory locations include all the I/O data (1-166), X Variables (201-424) and User Memory Locations (3000-11999).

BSHIFT(x, nbits, dir) Returns the value x shifted left or shifted right by the given number of bits (1-16). The value of dir specifies the direction of the shift (0=left, 1=right). Example: X1=BSHIFT(X2,8,1) This would return the MSB of X2 (X2 shifted 8 bits to the right)

BTST(mloc, bnum) Returns the value of a bit referenced with mloc given the bit number (0-15). (see the BSET function above)

CGBACKUP(gnum, nvloc) This function will back-up the given control group’s data (all 25 words) to the NVRAM location nvloc

(personality module) whenever a change is made to the group data. It will also restore the data from NVRAM to the control group if it detects invalid data (RAM failure or new RTU board?).

CGLEVEL(gnum, saddr1, ai#, saddr2, ai#, [...saddr8, ai#]) This function will return the lowest of the enabled controlling levels given the group # and a list of

station addresses and analog input numbers (1-8 or 9 for flow rate). It can be used in conjuction with the GROUP() function to allow multiple controlling levels. If no analog is enabled, a value of 65535 will be returned for pump-up groups, 0 for pump-down groups.

Example: X1=CGLEVEL(1,192,1,193,1) This would return the level from TH-AI1 or TI-AI1 depending on which level is lowest and is enabled

(not inhibited) in control group #1.

DIN(x [,value]) Returns the value for discrete input #x. The returned value will be 0 if the input is OFF and 1 if ON. If the optional parameter “value” is included, it will set the given discrete input to this value.

DOUT(x [,y]) Energizes or de-energizes output #x based on the value y. The value of y should be “0” to turn off an output and “1” to turn it on. Discrete outputs 1-8 will use the On and Off timer settings. This function also returns the current value of the output. If the optional parameter y is not given, it just returns the current value of the given output #.

DPVPFLOW(dp, dpe, vp, vpe, vsize, vtype, rexp) This function will return a flow rate given the differential pressure, valve position, valve size and type.

The following parameters are required: dp = given differential pressure dpe = exponent multiplier for dp (dp*10dpe) vp = given valve position (usually 0-100%) vpe = exponent multiplier for vp (vp*10vpe) vsize = valve size - valid sizes are 4,6,8,10,12,14 or 16 inches vtype = valve type (always 1 for now - Cla-Valve) rexp = result exponent multiplier (result*10rexp) Example: X1=DPVPFLOW(1000,-1,700,-1,16,1,0) returns a value of 32189.

ENTRYALARM(doors, opresent, alarmtime, exittime) The entry alarm function will return a value of “1” after a given door switch condition is tripped

and a timer times out without being acknowledged with the operator present signal. The following parameters are used:

doors = door switches (1=all closed) or a variable meaning that all is secure opresent = operator present key switch input or variable used to disarm (1=disarmed) alarmtime = time in seconds after doors are tripped and before the alarm condition is returned exittime = time in seconds allowed for the operator to exit after arming the system Example: DI5=ENTRYALARM(DI4,DI3,120,120)

EXIT() or EXIT(x) Exits the script immediately without processing any more lines. This can be used to bypass whole sections of code based on some condition. It can also be used to exit a subroutine and optionally return a value (x) to the main script.

FOR(var, start, end, step, statements) This provides for-next loop functionality using a loop variable and executing the given statements a

number of times (up to 100 iterations). The parameters are: var = control variable to be incremented in the loop start = starting value for the variable end = ending value for the variable step = number to add to the variable each interation (usually 1) statements = multiple statements separated by “:” to be executed each interation Example: FOR(X1,1,8,1,AOUT(X1,0):DOUT(X1,0):TSEC[X1]=0)

FPCONV(x, xexp, uloc) Converts the given integer value x to floating point using the exponent multiplier - x*10xexp

The result is stored at the given user memory location (32 bits are required to store the floating point number, so uloc and uloc+1 are both used).

Example: FPCONV(12345,-2,100) ‘this stores a value of 123.45 in M100,M101

FPSCL(uloc, fl, fh, sl, sh [,wswap]) Returns a scaled value given a floating-point number at uloc, min/max floating point value (fl and fh)

and the min/max scaled value (sl and sh). The uloc is the starting memory location for the floating-point number (since floating-point numbers are 2 words in length). This function is normally used along with the MESSAGE command to convert floating-point numbers from a PLC to unsigned integer values. The optional parameter “wswap” will swap the 2 words before doing the calculation if it is set to a “1”. This may be necessary when looking at floating point numbers obtained from certain controllers such as Modicon PLCs.

For example, if a Modbus speaking PLC has a floating point number located at 40001/40002, the following two lines of script could be used to read and convert it to unsigned integer:

MESSAGE(3,0,1,40001,0,2,3000) X1=FPSCL(3000,0,1,0,10000,1) ‘convert from 0-1 floating-point to 0-10000 integer, swap words

FPTOLONG(fpuloc, longuloc, wswap) Converts a 32 bit floating point number to an unsigned long integer given the parameters: fpuloc = user memory location of the float longuloc = user memory location for the unsigned long (2 words) wswap = swaps the floating point words before conversion if set to “1” Example: FPTOLONG(2000,2002,0) ‘convert float at M2000 to unsigned long at M2002

GOTO(x) Jumps to the given label x marked in script by a line containing the LABEL(x) function. Note: Only forward jumps are allowed to prevent endless loops. Also, if the label does not exist, the

script or subroutine will exit. Example: IF(X1>10,GOTO(100)) X1=X1+1 LABEL(100) X2=X2+1

GROUP(gnum, uloc, genable, gtype, clevel, psaddr, npumps, spump, penables, failsecs [,psaddr2, npumps2, spump2, psaddr3, npumps3, spump3, psaddr4, npumps4, spump4]) Control groups are used in conjuction with SCADAview 32 to do all the housekeeping for pump status,

alternation, fail generation etc. - similar to C2000 (CTU7-CTU9) based groups. The parameters are as follows:gnum group number (1-128)uloc memory location for the start of the crontol group data structuregenable group enable flag (1=enable, 0=disable) - group will alternate when disabledgtype group type (1=normal, 2=normal + RTU HOAs, 3=discrete given # of pumps, 4=discrete given # of pumps + RTU HOAs), 5=pump-down, 6=pump-down + RTU HOAs)clevel analog control level for comparison with stop/starts or the required # of pumps if using a type 3 grouppsaddr primary pump station address (0-255 = HH-WW)npumps number of pumps to control at the primary address (1-8)spump starting pump output number at the primary address (1-8)penables pump enable binary mask (0=no pumps enabled, 65535=16 pumps enabled)failsecs number of seconds to wait for a run before failing a pump (0=no fail)Optional parameters (psaddr2, npumps2, spump2 etc.) can be used to define up to 3 more pump station addresses and outputs to be controlled by the group. The maximum total number of controlled pumps is 16.The GROUP() function will return the current # of pump calls.

IF(x,y,z) If x is true evaluate y else evaluate z (else is optional). Multiple statements may be used for y or z by separating them with a colon.

Example: IF(DI1, DO1=1:DO2=1, DO1=0:DO2=0)

LABEL(x) Marks a line in the script that could be jumped to using the GOTO(x) function. This should be by itself on a line of script - see the GOTO(x) function for more info.

LISTEN(saddr, uloc, lostime [, ant#, rly1, ant1, rly2, dbrly, tbrly, pdaddr, pdoff, pdmask] ) Defines station addresses to listen for when using either Micro-Comm RTU/RTU32 (automote

messages or replies), old-style PDU messages or Modbus RTU Slave replies. When using Micro-Comm protocol, this function returns a “1” as long as the station is not in LOS. Also, the actual time in seconds since a reply was heard can be found in the station data structure.The parameters are:saddr address number (0-255 = HH-WW) or Modbus Slave address to listen foruloc starting user memory location for the station data structurelostime time in seconds before the LOS bit will be set in the station status byteant#, rly1, ant1, rly2, dbrly, tbrly - optional parameters that a central may need to talk to a non-polled remote (for remote HOA or Control Group information). These parameters are the same as shown for the MESSAGE function.pdaddr old-style PDU string address to listen for (PDU parameters are also optional)pdoffset starting location in pdu string for this station’s datapdmask data that is expected to be in the PDU string for this station (see the MPDU function)Example: X1=LISTEN(@PI,200,480)This would listen for station address “PI” and save the station data structure starting at user memory location 200. X1 will equal 1 as long as the station is not in LOS (480 seconds).Note: When using Modbus RTU Slave protocol, the reply data is just saved in a block starting at the uloc. The Modbus replies must be to “Read Holding Register” messages (4x registers).

MAVG(uloc, nwords) Returns the average value from a given range of user memory locations: uloc = the starting user memory address nwords = number of words to average

- 43 -

MCOPY(src, dst, nwords) Copies data from one area of user memory to another using the following: src - starting user memory location for the source data dst - starting user memory location for the destination data nwords - the number of words (16bit numbers) to copy Example: To copy the first 10 words from uloc 100-109 to uloc 200-209 MCOPY(100,200,10)

MCRC(uloc, nwords) Returns the CRC 16-bit checksum of a given range of user memory locations: uloc = the starting user memory address nwords = number of words

MDATA(uloc, d1 [,d2, d3, ...]) This function simply copies the given data words into consecutive user memory locations and returns

the total number of words copied. uloc - starting user memory location for the data d1, d2, d3, ... - data words to place into memory (can be as many as needed)

MDECTOHEX(dval, uloc, nchars) Converts an integer value to an ASCII hex string of characters located in user memory. dval - value to convert (16 bit unsigned integer) uloc - starting user memory location of the hex string nchars - number of hex characters (1-4)

MDISPLAY(row, column [,editflag]) Changes what is being displayed on the Micro-Comm Display Module by moving to the given row

and column. The “row” should be one of the following: 1=Analog Input Labels, 2=Discrete Inputs, 3=Discrete Outputs, 4=Timer Settings, 5=Stop/Starts, 6=X Variable Labels, 7=User Memory Screens.

If the optional editflag parameter is set to “1”, the displayed screen will immediately go into edit mode (just as if the user had pressed Enter).

Example: This will change the display to user memory screen #1 whenever an alarm input on DI3 goes on. The user memory screen should be set up to show an alarm message.

IF(OSR(DI3,0),MDISPLAY(7,1,0)) ‘ uses the one-shot function so that it won’t keep doing it.

- 49 -

MSGDONE(port, type, uloc [, sparam]) Returns the done status for a message given the port number, message type and uloc (these 3

parameters should uniquely identify the message). If both type and uloc are zero, a value of “1” will only be returned if all messages for the given port

are done. The done bit can also be set or cleared using the optional “sparam” parameter. If the optional “sparam” parameter is 0 or 1, the done bit will be set accordingly. Other parameter

values will do the following: 2 = returns the done counter (0-65535) 3 = returns the fail counter (0-65535) 4 = returns the done percentage x 100 (0-100% = 0-10000) 5 = resets both the done and fail counters Note: Whenever the done or fail count rolls over to zero, both counters will be reset and percentage

will go to 10000. Also, done and fail counters are incremented whenever a message is successful or unsuccessful (unlike the done bit status which get’s cleared based on the message command’s “lostries” parameter).

MSGNUM(port) Returns the current user message number pending on the given communications port (1-5). The message number is it’s location in the script with relation to other messages on the same port.

Message numbering starts at “1”.

MSUM(uloc, nwords) Returns the sum of a given range of user memory locations: uloc = the starting user memory address nwords = number of words to sum

MSYNC(sync#, uloc1, uloc2, nwords) Keeps two blocks of user memory in sync. If a word in block 1 changes, block 1 will be copied to

block 2 and vice versa. The parameters are: sync# - a unique sunc function number (1-64) uloc1 - starting user memory location for block 1 uloc2 - starting user memory location for block 2 nwords - the number of words to keep in sync (block size) Note: Block 1 is the “master” so if both blocks change, block 1 will be copied to block 2. Example: MSYNC(1, 100, 200, 100) ‘keeps M100-M199 in sync with M200-M299

MWRITE(uloc, y) Writes the 16bit variable or constant y to the user memory location specified by uloc (locations from 0-15999 are supported).

NVCOPY(src, dst, nwords, direction) Copies a block of data from the personality module NVRAM to User Memory or from User

Memory to NVRAM given the following parameters: src - source uloc or nvloc location depending on direction of copy dst - destination uloc or nvloc location depending on direction of copy nwords - number of 16bit words to copy direction - 0=NVRAM to User Memory, 1=User Memory to NVRAM

PID(t, ai#, ao#, p, i, d, min, max, start, dband, period) Sets the parameters for a real-time PID module. Setting “ai#” to 0 disables the PID. When re-

enabled, the analog output will start again at the “start” value. A total of 8 PIDs (one for each analog output) can be running at the same time. The PID will use a scaled value for the analog input and will internally keep track of a “raw” analog output value so that it can be scaled in the script as well. The PID() function will return the “raw” analog output.

t = target setpoint (0-4095) ai# = analog input # used (1-64) ao# = analog output # used (1-8) p = proportional term x 1000 (0-65535) i = integral term x 1000 (0-65535) d = derivative term x 1000 (0-65535) min = minimum analog output (0-4095) max = maximum analog output (0-4095) start = starting value for analog output (0-4095) dband = deadband (output will hold when input is this close to the target) period = time period in seconds for the PID calculation Example: AI1=SCALE(AI1,819,3604,0,255) ‘scale AI1 300# xdcr 4-20ma => 0-255 psi PID(X1,1,1,100,10,6,0,1000,500,20,4) ‘PID using AI1,AO1 and X1 target (0-255) AO1=SCALE(AO1,0,1000,819,4095) ‘scale AO1 0-1000 => 4-20ma output

Example: PITOAI(1,3,1000,4095,2) This converts a pulse of 0-10pps on PI1 to a value of 0-4095 on AI3. If 2 seconds goes by without

seeing a pulse, AI3 will be set to 0.

PMEM(x) Returns a byte from the RAM copy of the personality module configuration (locations 0-127). Refer to the personality module memory map for more info. Some locations will return current status information.

POLYNOMIAL(x, xexp, c, cexp, a1, a1exp, a2, a2exp, a3, a3exp, a4, a4exp, rexp) Computes the result of a 4th degree polynomial function: f(x) = const + a1*x + a2*x^2 + a3*x^3 + a4*x^4 x = given variable x xexp = exponent multiplier for x (10^xexp) c = constant value cexp = exponent multiplier for contant (10^cexp) a1,a2,a3,a4 = polynomial parameters a1exp,a2exp,a3exp,a4exp = exponent multipliers for parameters a1-a4 (10^aexp) rexp = exponent multiplier for the return value (10^rexp) Example: M1=POLYNOMIAL(M0,0,17879,-3,-40821,-4,34023,-5,-40364,-7,14639,-9,2) This computes the following polynomial and return the result *100. f(M0) = 17.879 - 4.0821*M0 + 0.34023*M0^2 - 0.0040364*M0^3 + 0.000014639*M0^4

POW(x, xexp, y, yexp, rexp) Returns the value of x raised to the y power. Pre-scaling and post-scaling is done using the given

exponent parameters. The result is rounded up to the nearest unsigned integer value. Equation used is: result = ( (x * 10^xexp) ^ (y * 10^yexp) ) * (10^rexp)

Example: X2=POW(222,-3,2,-1,4) would return a value of 7401 computed using: (0.222^0.2)*10000 = 7401

- 51 -

PUMPFAIL(callvar, runvar, tsec#, failsecs) Returns a “1” if the call variable has been equal to “1” for more than the fail seconds while the run

The parameter parameters are: callvar - call variable or expression (usually an output) runvar - run variable or expression (usually an input) tsec# - TSEC timer # to be used (1-224) failsecs - seconds before fail is generated Example: X1=PUMPFAIL(DO1TD,DI1,1,240)

RAMP(ramp#, startValue, endValue, rtimeSec) This will return the start value when first called and then will ramp up (or down) to the given ending

value over the given period of time (in seconds). The parameters are:ramp# a unique number for the function (1-8)startValue value to start with (when the function is first called)endValue value returned at the end of the ramp timertimeSec time period in seconds for the ramp to occurExample: AO1=RAMP(1,819,4095,120)This would ramp analog output #1 from 819 to 4095 over a 2 minute period.

RESPOND(saddr, uloc [,protocol [,nobuild] ]) Defines an additional station address for the RTU to respond as when polled with RTU32 protocol

or Modbus protocol if optional flag is set. The parameters are:saddr station address number (0-255 = HH-WW)uloc memory location for the station data structureprotocol when this optional parameter is a “1”, the given address and uloc will apply to Modbus

protocol instead of RTU32. In this case, the uloc defines a new starting location for the Holding Registers (4x0001). All other Modbus data types will remain the same.

nobuild when this optional parameter is set to “1”, the station status and timestamp will not be updated locally - this may need be used if all the station’s data is being read from another RTU using a protocol other than RTU32.

Example: RESPOND(129,3200) defines RTU32 address “PI” with station data located at 3200.

REPLYWITH(saddr, MR) Forces the reply message type to use when responding with RTU32 protocol. This could be used,

for instance, to send certain data only when necessary (report-by-exception). The parameters are:saddr station address (0-255 = HH-WW)MR read message type to reply with (see RTU32 Protocol table) - a value of 255 will cancel

the forced reply and go back to what is asked for.

RUNCOUNTER(cnum, cvar, uloc) Counts the number of “on” cycles for the given variable. The counter is incremented whenever the

value of cvar goes from zero to non-zero. The parameters are: cnum unique counter number (1-128) cvar variable or expression to count uloc user memory location used to store the counter (16 bit)

RUNTIMER(tnum, tvar, uloc) Provides a run-time meter on the given variable. The run time is incremented in 10ths of hours

- 52 -

SCALE(raw, rmin, rmax, smin, smax) Returns a scaled value given the actual raw value, the minimum/maximum raw values and the

minimum/maximum scaled values. Example: AI1=SCALE(AI1,819,4095,0,4095)

SELECT(test, value1, statement1 [, value-n, statement-n]) Similar to the IF function, SELECT will evaluate the given test expression and execute one of the

statements based on it’s value. If the test expression is equal to value1, statement1 will be executed. If test is equal to value2, statement2 will be executed and so forth. Multiple statements may also be used by separating them with a colon.

Example: SELECT(X1,100,DO1=1,200,DO2=1,300,DO3=1) This will turn on a discrete output based on the value of X1.

SFTABLE(addr1, addr2, antmask, timeout) Modbus RTU, DF1 Half-Duplex and DF1 Radio Modem protocols allow for relaying messages via

the “Store & Forward” method when using COM1. A lookup table is used to translate incoming message addresses to a relayed-to station address.

The following parameters sets up an entry in the Store & Forward table: addr1 address the master is using for the remote station being relayed to addr2 address this RTU will use to get the data from the remote station antmask antenna mask used for switching radios or antennas during the relay - this is an 8-bit mask applied to either DO1-DO8 or DO9-DO16 based on the configuration selection timeout amount of time in milliseconds the RTU will wait for a response

SQR(x [, xexp, rexp]) Returns the square root of x with optional parameters for pre-scaling and post-scaling. Equation used is: result = sqrt( (x*10^xexp) ) * 10^rexp Example: X1=SQR(256,-3,4) would return a value of 5060.

SDATA(saddr, word#) Returns the value of a given word number from the “Station Data Structure” for Micro-Comm

stations obtained using the MESSAGE() or LISTEN() functions. The station data structure is shown later in this manual.

Example: X1=SDATA(@TH, 4) returns the value for AI1 from station TH.SSTATUS(saddr, bit#) Returns the state of a given status bit number from the “Station Status” word for Micro-Comm

stations obtained using the MESSAGE() or LISTEN() functions. The following bits are defined: b7 (LOS) set when station goes into Loss of Signal (user defined) b6 (Data Valid) set when the received data is less than three cycles (tries) old b4 (Control Valid) set when data is first received and cleared at LOS

Example: X1=SSTATUS(@TH, 7) returns a “1” if station TH is in LOS.

SUB1(x)-SUB20(x) Calls a subroutine and returns the EXIT(x) value to the main script routine. Currently up to 20 subroutines are supported. Values can be passed to a subroutine using the following syntax: SUB1(x1,x2,x3,x4,x5) Where x1 through x5 are 16bit integer variables or constants passed by value to the subroutine. They become local variables referenced as L1 through L16 from within the subroutine. Example: The following shows the main script and a subroutine. The subroutine totals up the three values passed and returns the result to the main script. The main script stores the result in the

X1 variable. Main Script: X1=SUB1(1,2,3) Subroutine #1: L4=L1+L2+L3 EXIT(L4)

location 13), every time PI1 increases by 1200 (this could be a flow meter with 1200 pulses per 1000 gallons).

XCOPY(msrc, mdst, nwords) Copies data from one location in the RTU to another (including I/O locations) given the following

parameters: msrc - start modbus location for the source data mdst - start modbus location for the destination data nwords - the number of words (16bit values) to copy Note: msrc and mdst locations will correspond to the Modbus reference location shown in the DF1-

Modbus protocol table minus 400000. Supported memory locations include all the I/O data (1-166), X Variables (201-424) and User

Memory Locations (3000-11999). Example: To copy the first 16 discrete inputs to X2, the command is XCOPY(1,202,1)

Micro-Comm Script Language - RTU Processing Flow Chart

Much like a PLC processing ladder logic, the script is executed in a continuous loop.All I/O is read and written outside of the script so all changes made to inputs or outputswill actually occur when the script finishes.

Read Inputs

(analogs, pulses, discretes)

Run Script

Write Outputs

(start timers etc.)

Respond to Interrogations

Update the User Display

General Housekeeping...

Note: The M1550 can now respond to interrogations during script. This can cause undesired results when reading/writing user memory while this same memory is being manipulated in script. See the “MEMLOCK” variable for information on how to enable this feature. (setting MEMLOCK equal to 0 will allow incoming communications to access user memory)

Station and Group Data Structure

Note: Station data for the two local addresses (RTU #1 and RTU #2) will be created in user memory starting at 8000 and 8100 whenever their address is something other than “HH”. Additional “embedded” stations can be located anywhere as specified in the RESPOND() function.

- 59 -

LISTEN()

MESSAGE()(RTU/RTU32)

RESPOND()

Script functions can be used to build station data in 3 different ways:1) LISTEN() will passively save station data whenever it hears an RTU/RTU32 reply.2) RESPOND() will define a local station data structure and reply with the data when polled.3) MESSAGE() will actively poll a station and and save data from the reply.

Once built, SCADAview can then display and update this station data using CTU32 protocol. Command Update data (PC HOAs, etc) is obtained from the PC in this manner.

32 (20) Smart Poll (reply will be MR types $20-$2F)

Notes: Message Read Types $01-$0F request 12 bits (3 characters) for analog inputs. 16 bit (4 character) analog inputs can be read along with the other data using types $11-$1F. Messages that include the CFSYSHOA are reading the CALL/FAIL status bits and the System

HOA/Output Disabled status for up to 8 locally-controlled discrete outputs (as defined in a GROUP function). Smart Polling with Message Read Type $20 is different in that only non-zero data groups will be included in the reply (MR types $20-$2F). All other data groups will be assumed zero and analog inputs will be the 16 bit version.

Message Write Type:

MW (hex) Data Sent 0 (00) none

1 (01) DO1-DO8

2 (02) DO1-DO8,AO1-AO2

3 (03) DO1-DO8,AO1-AO4

4 (04) AO1-AO2

5 (05) AO1-AO4

Note: Message write types $01-$05 use 12bit analog data. 16 bit analog outputs can be sent using message types $11-$15.

Stop/Start Setpoints

Analog Level

Pump Enables

Group Enable

Compare the given analog level with up to 8 stop/start setpoints for the given total # of pumps and generate "n"

group pump calls.

Any Pumps Called Before Now?

No

Alternate by moving the lead pump pointer to the next available pump in the list.

Yes

Call on (n-N) additional pumps starting at the lead pump pointer and skipping over any pumps that are not available or are already being called.

Build list of available pumps (HOAs in auto, not failed, not disabled) - a zero for Group Enable or Time Clock reaching

the disable time will disable all pumps and trigger automatic alternation.

Too Many Pumps Called? (N>n)

Count the number of pumps "N" that are in AUTO and are already being called.

No

Call off (N-n) pumps starting after the first n pumps that were being called and are in AUTO.

Yes

Group already satified? (N=n)

Yes

All Done -Telemetry Call bits will now be set in station data structure for all pumps called.

No
