1 Operation

The programmable logic controller (PLC) is freely programmable. The controller is delivered without an executable application in the memory. The application must be developed sepa

rately for the desired purpose on a personal computer using ISaGRAF

(programming as in

IEC 61131-1) and then transferred to the controller. On start-up, after transferring the generated application, the current time and date must be set

in the controller (–> section 1.4).

2.1 Programming

Programming the PLC requires a PC with ISaGRAF®software.

The ISaGRAF needs of your plant (ISaGRAF

software enables you to program a control system that is tailored to the specific

development environment 1400-7621). Programming must fol low the structures and rules stipulated in IEC 61131-3. The PLC may be programmed with the languages defined in the standard: Sequential Function Chart (SFC), Instruction List (IL), Flow Chart (FC), Function Block Diagram (FBD), Ladder Diagram (LD), and Structured Text (ST).

There are 128 KB of memory available in the PLC for the ISaGRAF

application.

The application is complied to machine code in the PC environment. This code is then trans ferred to the PLC over the front RJ-45 jack (connecting cable 1400-7620).

Programming languages:

Sequential Function Chart (SFC):

Instruction List (IL): Low-level textual language for logic and arithmetic operations Flow Chart (FC): High-level language used to visualize the data flow Function Block Diagram

(FBD): Ladder Diagram (LD): Simple graphics-based language for logical operations (boolean) Structured Text (ST): High level language similar to PASCAL and C especially designed for

Used to describe operations of a sequential process with a simple graphic representation

Graphics-based language for building and combining complex functions (logical, arithmetic)

control applications

For operation and application of the ISaGRAF®environment, refer to the documentation in cluded in the software package. To enable simple and clear programming, ready-made func tions and function blocks, e.g. for boiler systems, heat exchanger sequence control, ventilation systems, heating circuits or domestic hot water systems, are available from SAMSON.

5 Communication

5.1 Modbus slave interface

The PLC can communicate with a control system using the RS-232 Modbus slave interface. To gether with the suitable process visualization software and communication software, a com plete control system can be implemented. The following interface settings are possible:

– Operation with a dial-up modem on the RS-232 Modbus slave interface Basically, communication is only establishedautomatically when the application has been con figured to dial when a fault occurs. The controller works autonomously. Nevertheless, the mo dem can dial up to the controller at any time to read data from it or change settings, if neces sary. The use of the modem connecting cable (1400-7139) is recommended.

– Operation with a leased line modem on the RS-232 Modbus slave interface Communication is established over a permanent connection between two leased line modems. This setup is applied for long-distance transmissions or when different signal level converters are used. The connection between the controller and the modem can also be established over the modem connecting cable (1400-7139).

– Operation on a four-wire bus To link the controller and the bus line, the signal level needs to be converted by an appropriate converter (SAMSON cable converter 1400-7308).

Modbus slave interface RS-232

The Modbus connection is located on the rear panel of the controller housing (RJ 12 jack). The controller can be connected either directly to the serial interface of a PC (point-to-point connection) or to a (dial-up) modem. A dial-up modem is required if the controller is to be connected to the telecommunications network. In this case, the controller operates autonomously and issues an alarm to the building control station (GLT) when faults occur. In addition, the building control station can dial up to the controller and read data from it.

Communication

Modbus slave interface in combination with RS-232/RS-485 cable converters (for four-wire bus)

Operating the PLC in combination with cable converters requires a permanent bus connec

tion (data cable). The bus line links the devices/control units in an open ring. At the end of the bus line, the data cable is connected to the control station using an RS-485/RS-232 con verter (e.g. TROVIS 5484). The maximum extension (cable length) of the bus line is 1,200 m. A maximum of 32 devices can be connected to such a segment. If you wish to use more than 32 devices or need to bridge greater distances, make sure repeaters (e.g. TROVIS 5482) are installed to replicate the signal. In all, a maximum of 246 devices can be connected to a bus line.

Caution!

Make sure that the relevant standards and regulations concerning lightning and overvoltage protection are observed upon installation.

5.2 Modbus master interface

Modbus instruments can be connected to the PLC using the RS-485 Modbus master interface. The maximum bus line is 1,200 m. If you need to bridge greater distances, make sure repeaters (e.g. TROVIS 5482) are installed to replicate the signal.

Terminals 1 and 2 are used for connection (see Fig. 4).Up to four expansion modules can also be connected in parallel to these terminals. Refer to section 8.4.3 for more details.

Caution!

Make sure that the relevant standards and regulations concerning lightning and overvoltage protection are observed upon installation.

5.3 Description of communication parameters to be adjusted

Station address

This address is used to identify the PLC in bus or modem operation. In a system, each controller needs to be assigned a unique address.

Addressing/16-bit addressing

Selection between 16-bit addressing or 8-bit addressing Select RS-232/Slave menu item (under

16-bit addressing? Yes – 16-bit addressing

16-bit addressing? No – 8-bit addressing

Station address

Baud rate

The baud rate setting refers to the transfer speed between the Modbus instruments.

Control system monitoring

Any intervention made by the control system on dynamic processes are restricted in time, pro vided that communication between the control system and the controller is not established. The controller resets the time monitoring after every valid retrieval of the station address. After the defined maximum time has elapsed, all even bits are reset to “autonomous“.

Communication

Modem

Modem = On:

PLC connected to telecommunications network over a modem (RS-232 Modbus slave in terface) Modem = Off:

PLC directly connected to a computer (RS-232 Modbus slave interface) and on operating the PLC in combination with cable converters (RS-232/RS-485)

Cyclical initialization

This parameter defines the period of time for a cyclical issue of the initialization command “ATZ“. The command is not issued during dial-up or when connected.

Automatic disconnection

When the controller connects to the building control station but without addressing a Modbus data point, the PLC closes the connection after the time specified for has elapsed.

Gateway

Gateway = On:

Any polling by the building control station to the Modbus instruments connected to the PLC is passed directly on to the slaves. Gateway = Off:

Any polling by the building control station to the Modbus instruments connected to the PLC is not passed directly on to the slaves.

Automatic disconnection

Frame

Frame = On: Framing function activated

Frame = Off: Framing function deactivated

Bias voltage

We recommend applying a bias voltage on the bus to keep the signal level stable. This bias volt age is usually applied to the bus by the Modbus master.

Bias voltage = On: Bias voltage on the bus

Bias voltage = Off: No bias voltage on the bus

Communication

Validity

The values saved in the PLC, which have been sent by the slaves, have a time-dependent

Validity

. If the building control station polls the saved data within the valid period of time, the PLC sends the saved data directly to the building control station. However, if the polling to the PLC is outside of this valid time period, the PLC first polls the slaves and then sends these updated data to the building control station.

Pause

The time entered in responded to the last polling by the PLC.

Timeout

is the time that elapses before the PLC polls a slave after it has

If the slave does not respond to a PLC polling after the time in generated.

Expansion module (1400-9386)

Expansion modules are connected by specifying their station address. This station address can be entered in default state (reset over the jumpers) using the last two figures of the serial numbers.

Example:

The serial number 600116 means that the station address is 16. This can only be dialed by the broadcast function when one expansion module is connected.

5.4 Meter bus interface

Thanks to the meter bus interface, the PLC can communicate with up to 3 heat and water meters according to EN 1434-3. Details onthe useof the different heat and water meters can be found in the technicaldocumen tation TV-SK 6311.

5.4.1 Activating the meter bus

To successfully transfer data from the heat meter (WMZ) to the PLC, the heat meter must use a standardized protocol in accordance with EN 1434-3. It is impossible to make a general state ment about which specific data can be accessed in each meter.For detailson thedifferent meter makes, refer to the technical documentation TV-SK 6311.

The model code, which needs to be set for the respective heat meter, can be found in TV-SK 6311. In general, the default setting of 1434 can be used for most devices. Reading mode [Coil, Cont, 24h]

The meters can be read either automatically approx. every 24 hours (24h), continuously (con) or when the coils (= Modbus data points) assigned to the heat meters WMZ1 to WMZ3 are overwritten with the value 1 over the system bus interface (Coil).

All settings that are made for communication with heat or water meters are stored in Settings level > Meter bus > WMZ#_. Set the parameters in the following sequence: – Model code – Reading mode – Meter bus address

Note!

With reading mode “24h“, the displayed values are not updated by reading the status information again; the values read during the last cycle remain unchanged. With reading mode “con“, the values in the levels are not continuously updated. Reopen the specific level to get current values.

Meter bus address (Addr?) [0 to 255]

A meter bus address must be unique and correspond with the address preset in the WMZ. If the preset meter bus address is unknown, a single heat meter connected to the controller can be assigned meter bus address 254. Address 255 deactivates communica tion with the respective heat meter.

Caution!

For electrical connection of the PLC, you are required to observe the relevant electrotechnical regulations of the country of use as well as the regulations of the local power supplier. Make sure all electrical connections are installed by trained and qualified personnel!

Notes on installing the electrical connections

Install the 230 V power supply lines and the signal lines separately! To increase noise im

munity, observe a minimum distance of 10 cm between the lines. Make sure the minimum distance is also observed when the lines are installed in a cabinet. The lines for digital signals (bus lines) and analog signals (sensor lines, analog outputs)

must also be installed separately. In plants with a high electromagnetic noise level, we recommend to use shielded cables

for the analog signal lines. Ground the shield at one side, either at the control cabinet inlet or outlet, using the largest possible cross-section. Connect the central grounding point and the PE grounding conductor with a cable≥10 mm² using the shortest route. Inductances in the control cabinet, e.g. contactor coils, are to be equipped with suitable

interference suppressors (RC elements). Control cabinet elements with high field strength, e.g. transformers or frequency conver-

ters, should be shielded with separators providing a good ground connection.

Overvoltage protection

If signal lines are installed outside buildings or over large distances, make sure appro

priate surge or overvoltage protection measures are taken. Such measures are indispen sable for bus lines! The shield of signal lines installed outside buildings must have current conducting

capacity and be grounded on both sides. Surge diverters must be installed at the control cabinet inlet.

Noise suppression

The TROVIS 5571 Controller with SAMSON actuator is interference suppressed according to VDE 0875. If different actuator makes are used, or moreover, further actuators with interfer ence sourcesare usedin a plant, the operator/supplier of a custom-made plant must makesure that the entire plant complies with VDE0875 regulations due to thelegal obligation of ensuring interference suppression.

Electrical connection

Connecting the PLC

Open the housing to connect the cables. Make holes in the marked locations at the top, bottom or back of the housing’s back panel and fit suitable grommets or screw joints. Observe the diagram (Fig. 4) for connection. The connection diagram contains all possible in puts and outputs. The assignment of the corresponding inputs and outputs is determined by the respective application.

Inputs

When wiring the universal inputs (BE1/AE1 to BE17/AE17), make sure to use terminal 13 as ground in case of active inputs (current and voltage inputs). If the universal inputs are used as passive inputs (sensors or binary inputs), terminal 10 must be used as ground. Binary inputs with terminal 10 functioning as ground (GND) are slow (a delay of approx. 3 sec onds). Binary inputs with terminal 9 functioning as ground (GND) are fast (ms).

Outputs

The binary low-voltage outputs (BA1 and BA2) are used for signaling. As a result, only a minimal load can be applied to these outputs (50 V DC, max. 100 mA ohmic load). If greater loads are to be applied, it is recommended to control relays over theoutputs whichthen switchthe elevated load. The 10 binary outputs (BA3 to BA12) can be loaded with max. 250 V AC, 2 A.

Modbus

The control station is connected over a serial RS-232 interface at the back of the controller. Further Modbus instruments (slaves) are connected to the PLC over the RS-485 interface

(terminals 1 and 2).

Connecting the sensors

Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the back panel of the housing.
