Figure 1 Basic Unit

The Modicon A120 is a DIN-rail mount controller with front connection for smaller tomiddle-sized automation tasks. According to your applicational needs you can chooseone of the three CPUs with different functionalities:

ALU 200 ... 202L 4 to max. 12 log. instructions, for serial applications and as the telecontrol substationGaedat 120.

ALU 204, 205 30 / 90 log. instructions, for applications which come close to the performance of A250.

The A120 provides the following automation functions according to the scope of expan-sion:

Controlling and computingClosed-loop controlMeasured-value processingSignalling and monitoringPositioningIndirect addressing (in connection with ALU 204 / ALU 205)Fuzzy-logic (in connection with ALU 204 / ALU 205)Sequence control system (in connection with ALU 204 / ALU 205)Diagnosis (in connection with ALU 204 / ALU 205)Visualizing (Viewstar, in connection with ALU 202 ... 205)Communication (in connection with ALU 202 ... 205 oder KOS)

The backplane is mounted on a top hat rail. The modules are inserted in the backplane(see Figure 1).

1.2 How the Components Work together

The mode of operation of the A120 (compare Figure 2) is determined by the combinedcoordination of:

Controller (CPU)MemoriesI/O Modules

Program MemoryRAM

Basic SoftwareEPROM / (RAM)

Signal MemoryRAM

CPU I/OModulesPAB

EPROM-Card

EPROM-Programming Station

1.2.1 The CPU: Purpose and Mode of Operation

The CPU contains the processor of the A120. It executes the individul instructions of aprogram according to the regulations preset by the basic software. It organizes thereading of external data and signals into the signal memory, processes this data andcarries out calculations, queues continuous processing results in the signal memoryand realizes the output of the results.

Moreover, the interfaces for the communication with other programmable controllers(only the ALU 202) and for the programming panel connection port are located in theprocessor.

1.2.2 The Memory: Purpose and Allocation

The memory is subdivided into 3 parts:

Program Memory (RAM or EPROM)Basic Software (EPROM or EPROM card)Signal Memory (RAM)

The user program is located in the user program memory which effects the control se-quence. The is either loaded from the EPROM card, which was placed into the ALU(see Figure 2) or loaded directly from the programming panel into the RAM.

The process picture (I/O bits, markers, counter and timers) is filed in the signalmemory. User programs always work with the data from the signal memory and not

with the input and output signals themselves.

1.2.3 I/O Modules: Purpose and Types

All the modules which directly effect the process are I/O modules. The following belongto this group:

Input/output modules for processing discrete signal states

Input/output modules for the processing of analog signals

Counter modules

Textual modules for the process dependent text output e.g for fault signal logs

Consoles for the parameter assignment of the time values/number values (time mod-ule / counter module)

Empty modules for the fixing of lines, which are not required, or for the prewiring ofreserved slots

1.2.4 Busses

I/O modules are linked to the CPU via the parallel I/O bus (PAB1) which is located onthe back of the backplane. Contacting the modules using the bus is effected automati-cally when the module is clipped on.

1.3 General Assembling

The A120 consists of a basic unit and up to 3 expansions (compare Figure 3) accord-ing to your application task.

The basic unit consists of:

A basic backplane DTA 200, CPU ALU 200 with integrated supply voltage moduleand up to 3 I/O modules

or

a basic backplane DTA 200, a CPU ALU 201L, backplane supply power DNO 201 orDNP 205 or DNP 210 and up to 2 I/O modules

or

A basic backplane DTA 200, a CPU ALU 202L or ALU 204 ALU 205, a backplanesupply power DNP 205 or DNP 210 and up to 2 I/O modules

An expansion consists of:

An expansion backplane DTA 201 with up to 5 I/O modulesor

an expansion backplane DTA 202 with up to 2 I/O modules

Table 5 (page 18) presents an overview of the modules available.

* The I/O modules with 16 I/O points are taken as a basis. If the modules are used with fewer I/O points

(analog I/O, relay A, ...) the specified maximum value is reduced accordingly.

** The expansion which is based purely on a computed maximum numbervalue is not reached in practice by

using special modules and analog I/O.

1.4 Types of Communication

1.4.1 Overview

In the broadest sense of the word the term networking refers to the connection of twoor more intelligent modules (networking nodes) for data exchange purposes. Thetransmission path on which this data exchange is handled is designated as bus. Thedata which has to be transmitted (relaying a message) is coded and transmitted in theform of telegrammes. The type and way of coding (telegramme structure) and the typeof transmission (serial/parallel) is called the networking procedure.

Telegrammes can basically only be sent on command. One node is specifically entitledto give commands on the bus. It is called master and can communicate with all theother nodes. The master is defined according to the networking procedure on a hard-ware basis or on a software basis. All the remaining networking nodes are calledslaves. They can only communicate with the master.

Different types of busses are used at the various levels of the hierarchy in a networkedautomation system which is based on changing transfer requirements (e.g. datathroughput, transmittal speed), but these are not absolute assignments:

1.4.2 Modnet 1/SFB Interfaces

The Modnet 1/SFB is a serial data bus that establishes the connection between seve-ral networking nodes. It facilitates (DEA procedure) the operation of modules (discreteI/O, analog I/O as well as intelligent function modules).

BIK modules serve as interface for the transmission and reception of data telegrams.They establish the data transfer between the CPU and the remote I/O.

Another area of use for this bus is networking. In such an application it can be usedwhen configuring the data path between two programmable controllers that have to belinked together (1N procedure).

Modicon A120 with ALU 204 or ALU 205 can communicate with other devices through

a Modnet 1/SFB interface on Modnet 1/SFB as master or slave (refer to Figure 5). 1Nas well as DEA protocols can run across this bus. The interface used for this connecti-on is an RS 485 port which is located on the ALU.

1.5 Programming

1.5.1 Special Programming Language

AKF12 or AKF125Structured programming is created off-line in Dolog AKF (acc. IEC 1131-3). In additionthere are a number of support and assistance programs for initial start-up. Chapter 1.8contains an overview.

Sequence Control System (SCS)Diagnosis (Diag)

The detailed description of the programming is avilable in the documentation belongingto the software kit.

7/22/2019 Plc a120 Aeg

24/23627General12

1.5.2 Program Generation

Programming with the A120 is done off-line. In off-line programming the program is ge-nerated on an IBM-compatible PC (refer to 1.5.3) and subsequently transferred to thePLC. In contrast to on-line programming this does not require communication betweenprogramming device and PLC during program generation which means that the pro-gramming task for the A120 can be carried out at a different location. It is, however, ne-cessary to work with programming software (AKF125 or ALD25) that must be orderedseparately.

Program Structure

The structuring of a program means creating transparent and clear, self-contained partsof the application program. These parts are called blocks.

Technology-specific and repeatable sequences can be used a number of times as de-bugged subprograms within a plant or as technology blocks. Function blocks can becompiled into both general-purpose and application-specific program libraries. Standardfunction blocks for complex control, data-handling and operating functions, integratedinto the PC*, form the foundation for simply creating complex and application-specificsoftware blocks.

The blocks are composed of networks, the latter representing the lowest level of thestructure. Then user programm is composed of operations, which are assigned with pa-rameters (called instruction in instruction list).

Figure 7 shows an example of the different structures.

Chapter 2Operating

This chapter deals exclusively with the themes which are relevant to theoperator of an A120 which runs on the process arranged according tooperating elements and display elements as well as simple maintenancework. It shows how to build an operator interface and supplies refer-ences which are of importance during the programming of system and/oruser-specific operating instructions and maintenance plans for the A120.

7/22/2019 Plc a120 Aeg

34/23627Operating22

2.1 Display Elements

Most modules have LED displays at their disposal for diagosis purposes. There aregreen, yellow and red LEDs and they have the following basic meanings (deviationsare possible):

Green LED The LED is on if the supply voltage, switching voltage or sensor power supply which isrequired by the corresponding module is available.

Yellow LED The LED is on if a processor which is available on the module is operating. In I/O mod-ules, it signals an overload or a short circuit.

Red LED In I/O modules the red LED signals a 1 signal to the corresponding inputs and out-

puts. Otherwise, its meaning is specific to modules.

You will find a list of display elements of each module together with the special mean-ings under chapter 2 of each module description.

2.2 Switches

The A120 does not have any switches which are exclusively specified for the operation.Correspondingly, no switches are accessible if the front panel is assembled.

Details regarding the switches are provided for configuration and maintenance can beconsulted in the descriptions of the modules for the corresponding modules.

Note The DIP switches on the ALU which are accessible after removing the front pan-el of the DTA 200 are configuration settings !

2.5 Switching the Supply Voltage on and off

Switching the supply voltage on or interrupting the supply voltage occurs when:

The system is switched on and off by the userThe switching on and off of the system as a result of a power failure

In both cases, one must ensure that no dangerous processing conditions can arise dur-ing the voltage loss or in case of a voltage recovery. This is of special importance inthe event of a power failure, since the voltage recovery can be effected by the user atan indefinite period of time in contrast to the switching on and off of the system.

2.5.1 Switching the System on and off by the User

The programmable controller is switched on and off via the central power supply. Checkthat all the measures mentioned in point 2.5.3 have been guaranteed before switchingoff.

2.5.2 Switching the System on and off as a Result of a Power Failure

The hazard of a power failure is a permanent risk. Always ensure therefore that all themeasures mentioned in point 2.5.3 have been guaranteed.

2.5.3 Checking Measures (Inspection)

Always ensure that the back-up battery(ies) are intactEnsure that the CPU is equipped with at least one working battery so that programsand data are not lost in the event of a failure in the supply voltage. Used batteries musttherefore be replaced immediately. It is recommended to use two batteries in order toincrease the back-up time.

Do not change DIP switch settingsThe start-up characteristics of the programmable controller is dependent on the prob-lem definition determined during configuration phase and set via the DIP switch on theCPU. The latter may therefore in principle not be changed (basic regulation). Excep-tions to this rule should be mentioned explicitly.

Note The battery can be waived only if IL and KOS parameters are stored inEPROMs.

3.1 Overview

For device layout you have to configure:

Equipment and I/O node determination as well as total current at the I/O bus(see chapter 3.2.1, page 29)

Power supply for supply voltage UB (see chapter 3.3, page 33; chapter 3.3.2,page 36 and chapter 5, page 99)

Power supply for working voltage US (see chapter 3.3, page 33; chapter 3.3.3,page 45 and chapter 5, page 99)

Cabling of the sensors (see chapter 3.3.2, page 36 and chapter 5.2, page 105)

Cabling of the actuators (see chapter 3.3.3, page 45; chapter 5.2, page 105and chapter 5.4, page 112)

3.2.2 Total Current

Check, if the selected power supply ALU 200 or DNO 201 or DNP 2xx or DEA 20x issufficient for supply of all I/O bus nodes.Table 10 shows a list of all nodes with a maximum loading (current sink).

A power balance is automatically created by PRO-x120 during configuration.

In the same way the loading for the dimensioning of the 24 V power supply can be de-termined.

3.3 Layout of Power Supply

As the 24 VDC power supply for the A120 modules, the sensors and the actuatorsthree phase bridges without smoothing are sufficient. Monitoring for phase failure isnecessary in this case due to the max. allowable ripple of 5%. For single phase rectifi-cation the 24 VDC should be buffered in such a way, that the specifications given inchapter 4.2, page 83 are satisfied (UB = 20 ... 30 V; max. 5 % ripple)

At the entry of the fused supply voltage in the system an overload protection (suppres-sor diode) should be connected. See Figure 10.The suppressor diodes, e.g. surge voltage protection OVP 2480 should be wired asquadripoles and arranged with low impedance reference conductors near to the powersupply.

Every derivation has to be protected by a fuse and should be wired using a suppressordiode if long lines are used, e.g. 1N5646A, AEG E-No. 424 152 500.The fuse was to beadapted to the remissible current loading of the used suppressor diode. The advantageof this arrangement lies in the selective switching off of a branch via the associatedfuse, even if there is a short circuit in the diode.In environments where the risk of being struck by lightning is high, additional lightningprotection arrangements have to be made.Please see: chapter 5.1.3 Functional Earthing and chapter 5.1.4 Reference ConductorSystem.

The working voltages are combined for several outputs (correspond to a group). Everygroup has to be separately protected with a fuse.Please ensure that no unpermissible surge voltages occur which are caused by switch-ing inductive consumers. The latter can lead to risk of or destruction of semi conductorsin the programmable controller.

3.4 Start-Up Characteristics

Please configure a main switch that can be operated mechanically for switching sup-ply voltage on and off. You have to integrate supply of the A 120 and supply of thesensors and actuators.In case of danger for man and machine please configure an additional emergency-out-equipment according to chapter 5.5 (page 114).

Determine the kind of start-up characteristics (cold restart / hot restart / manual start/ automatic start) by setting the DIP switches B0 and B1. For more details, see theresp. module description of the ALU.

Please make sure that no dangerous process conditions arise during voltage failure or

voltage recovery. Especially consider this during powerfail, because voltage recoverycan happen at an undefined moment in contrast to switching the system on and off.

Note: At Geadat 120During normal telecontrol processing the dialog with substations is exclusively executedby the telecontrol master station. For operation on-site a PADT is used.

3.7 Configuration of the SystemFieldBus Line

3.7.1 Transmission Rates (Baud Rates) of the SystemFieldBus Interface

Data transfer occurs according to baud rate either in self-clocked-mode.To guarantee correct data transfer, the cable lengths listed in Table 11 must not be ex-ceeded.

Table 11 Transmission Rate and Core Number Depending on Cable Length

Baud Rate Max. Bus Length

62,5K baud 1200 m

375K baud 300 m

Each field bus line from devices with several Modnet 1/SFB interfaces can be set toanother baud rate.The baud rate on ALU and DEA is set with a DIP switch (refer to Description of Modu-les) and must be uniform within a field bus line.

3.7.2 SystemFieldBus Connection

The bus cable that enables interactive networking of ALU / DEA (slave) to ALU (master)must be built by the user. To do this, the BBS 1 connector and the JE-LiYCY cable are in-dividually available. Ordering instructions for the bus cable (by the meter) and the BBS1connector can be found in Chapter 4 of the module description (ALU 202). For distancesof less than 0.5 m, the already assembled YDL 40 cable can be used.

The cable is fed from DEA to DEA (bus networking) beginning at the master (ALU) withdouble assignment of the terminals.

Step 3 Turn the cable shield CS over the PVC sheath PV.

Step 4 Wrap as shown in figure (right) the overlapping cable shield with the enclosed Cu-foilshield CF.

Step 5 Use as shown in the Figure 47, to fasten both cables in the area of Cu-foil shield (en-sure permanent cable shield bonding).

Step 6 Connect the individual cores according to their colors as per Figure 47.At 62.5 or 375K baud a connection to the ports 3 and 8 (two-wire port) is sufficient.

Step 7 If only one cable is connected to BBS 1 (beginning of bus and end of bus), the termina-ting resistors marked A in Figure 47 are preserved.If two cables are connected (looped-through bus) the terminating resistors (diagonalcutters) are removed. Close the BBS1 connector (cover and screws in separate plasticbags).

Step 8 Plug BBS1 onto ALU and DEA and tighten screw.

Step 9 Execute the discharge measures of the shield according to Chapter 3.7.4, page 69.

3.7.4 Modnet 1/SFB Discharge Measures

In case the ALU 202 is used as slave on Modnet 1/SFB, prepare the bus cable asshown in chapter 3.7.3, page 67. The shielding on the system field bus (SFB) as node(slave) should not be grounded directly due to the transient currents.Therefore the ALU 202 should be grounded only via the capacitive discharge terminal.

3.7.5 Surge Voltage Protection for SystemFieldBus Cable Outside Build-ings

In order to protect the transmission appliances, e.g. Modnet 1/SFB, from networkedsurge voltage (lightning bolt) it is recommended to use a surge suppressor in the dis-tributor mains. The rated leakage current should thus be 5 kA at least, e.g. type ARE,Order No. 919 232 to be ordered from:

Fa. Dehn und ShneMail Box92318 Neumarkt 1

For the protection of one Modnet 1/SFB cable two lightning ductors ARE in each build-ing are required.
