development environment 1400-7621). Programming

struction 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 programmed application is complied to machine code in the PC environment. This code is then transferred to the PLC over the front RJ-45 jack (connecting cable 1400-7308).

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

2.5 Configuring the universal inputs

Note!

Connect a 50 When the inputs (0 to 10 V or 0(4) to 20 mA) are active, use terminal 13 for GND instead of terminal 10.

17 universal inputs are available. The inputs can be configured to serve as a binary, analog (0 to 10 V, 0(4) to 20 mA) or sensor input. The hardware must be configured accordingly (sensor initialization).

The sensor resistance values can be found on page 44. The following applies:

CO6 -> Fb00 = ON: Pt 100 and Pt 1000 mixed (default)

CO6 -> Fb00 = OFF: Pt 100 and PTC mixed

Each universal input can also be configured separately. The following function block parameters are available: Pt 100/500/1000/2000, Ni 200/1000/2000, PTC, NTC, OHM (1-2 kΩ), BE, 0(4) to 20 mA, and 0 to 10 V (model no. 5171-0003 and higher).

5 Operational faults

If the corresponding universal inputs are configured as sensors using CO6 -> FB01 to FB17 = ON, a sensor failure can be detected, processed, and indicated (text message, fax).

5.1 Error status register

In the INF8 level, the bits of the error status register are indicated. The error status register (holding register - 16 bit) HR 60 serves as indicator for faults of the controller or the plant. In modem mode (CO9 -> FB01 = ON), a change in status of HR 60 triggers a dial-up connection to the building control station.

Note!

Error status register HR 61 is displayed in the PLC but not used for fault indication.

5.2 Fault alarms

Fault alarms can be forwarded either directly to the process control station over a modem, to a mobile phone over the SMS function or to a fax machine. Only one function (Modbus, SMS or fax function) can be selected at a time as the functions use the same interface. Fault alarms forwarded to a mobile phone or fax contain the number of the affected error status register (FSR1), the fault as specified in the error status register (BitNo), the short des ignation of the device, and the bit number (Bit xx).

5.2.1 Sending SMS text message in case of a fault

Currently, fault alarms can only be forwarded to mobile phones in the German D1 network. The appropriate D1 network access number as well as the recipient’s mobile phone number must be entered in PA9 parameter level:

D1 network access number: 0171 252 10 02

(place an additional 0 in front when dialing from a private branch exchange) Numbers 0 to 9, P = pause, - = end, max. 22 characters The network access number is issued by the network operator Deutsche Telekom and may change without notice. Recipient’s mobile number: 49 xxx yyyyyyy where

xxx stands for 171, 160 or any other valid D1 dialing code and yyyyyyy represents the recipient’s phone number Numbers 0 to 9, P = pause, - = end, max. 14 characters

Note!

At the moment, SMS fault alarms cannot be sent to any other mobile phone network than D1.

Communication

6 Communication

Using the serial system bus interface, the PLC can communicate with a building control station. Together with the suitable process visualization software and communication soft ware, a complete control system can be implemented. The following interface settings are possible:

– Operation with a dial-up modem on the RS-232-C system bus interface Basically, communication is only established automatically when faults occur in the plant. The controller works autonomously. Nevertheless, the modem can dial up to the controller at any time to read data from it or change settings, if necessary. The use of the modem connecting cable (1400-7139) is recommended.

– Operation with a leased line modem on the RS-232-C system bus interface Communication is established over a permanent connection between two leased line mo dems. This setup is applied for long-distance transmissions or when different signal level con verters are used. The connection between the device 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).

6.1 RS-232-C system bus interface

Communication

The system bus connection is located on the rear panel of the controller housing (RJ 12 con nector). The device 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 con troller is to be connected to the telecommunications network. In this case, the controller oper ates autonomously and issues an alarm to the building control station (GLT) when faults oc

cur. In addition, the building control station can dial up to the controller, read data from it, and transfer new data to it after the valid key number has been written to holding regis

ter 40070. If the key number was accepted by the controller, register value “1“ indicates write permis

sion. Otherwise, the register value remains “0“. Write permission must be obtained upon each connection by sending the key number.

Note!

If an invalid key number is written to holding register 40070 for the third consecutive time, the controller immediately interrupts the modem connection and activates bit D6 in the error status register (Unauthorized access occurred). As a result, an alarm call is triggered to the configured control system or an SMS text message/fax is sent. Bit D6 is reset as soon as the error status register was read by the control system and the connection was terminated.

In special cases, the Lock dial-up function can be selected to stop dial-up in case of faults. Using the Dial-up also upon corrected fault function, the controller additionally informs the building control station when a previously signaled fault no longer persists.

6.2 System bus interface 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.

6.3 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 con troller needs to be assigned a unique address.

Baud rate

In a bus system, baud rate refers to the transfer speed between the control system and the PLC. In modem mode, the parameter refers to the transfer speed between controller and mo dem. The baud rate adjusted on the PLC must correspond to the baud rate of the control system, otherwise no communication can be established.

Cyclical initialization (I)

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. “ATZ“ causes the con figuration profile 0 to be copied to the active profile, provided the modem parameters have been set and saved in profile 0 using a suitable terminal program.

Sample initialization of a modem with a terminal program:

AT & F (restores modem to its factory settings) OK (response of the modem) ATEOSO = 1 (EO: echo off;

SO = 1: answer on first ring)

Modem dialing pause (P)

It is recommended to observe an interval of approx. 3 to 5 minutes between dialing up to the control system, text messaging center or fax machine to avoid a permanent overloading of the (telecommunications) network. The modem dialing pause is the interval between two dial ing attempts.

Modem time-out (T)

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 elapsed. If the error status register was not read during this connection, the PLC dials up to the GLT again after the

No. of redialing attempts (C)

6.4 Meter bus interface

Communication

Thanks to the meter bus interface, the PLC can communicate with up to 3 heat and water me ters according to EN 1434-3. Details on the use of the different heat and water meters can be found in the technical documentation TV-SK 6311.

6.4.1 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 statement about which specific data can be accessed in each meter. For details on the different meter makes, refer to the technical documentation TV-SK 6311. All necessary function block parameters to set up communication with heat or water meters are available in CO9 -> FB21 to FB23. The meter bus address, the model code, and the reading mode must be specified. 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 communication with the respective heat meter. 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.

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).

EB 5171 EN 29

Communication

In INF9 info level, “1434“ is displayed when the meter bus is activated. Press the enter key to get to the display referring to the meter bus. For each of the three heat meters whose address is not 255, “buSi“ (with i = 1, 2, 3) is indicated. Press the enter key again to display the fol lowing information about the associated meter:

7 LON communication

Note!

The following section only applies to devices with LON interface and CO7 -> FB00 = ON. On connecting LONMARK devices, CO7 -> FB00 = OFF needs to be configured.

Using LON, the inputs and outputs of max. 20 Series 5100 Controllers can be read. The connected controllers transmit their inputs and outputs as well as the pulse counter and its pulse length to the PLC over LON.

Each controller is assigned a LON station address, which needs to be set in parameter level PA7. A station address in a subnet must be unique. Each controller type is assigned its own subnet. This means that identical LON station addresses can be assigned for different controller types, e.g. 5174 and 5179, as they belong to different subnets.

Controller type Subnet Station address

TROVIS 5171 1 1 to 20 TROVIS 5174 4 1 to 20 TROVIS 5177 7 1 to 20 TROVIS 5179 9 1 to 20

Moreover, a master PLC can control the binary outputs of four additional TROVIS 5171 Controllers (–> max. 60 binary outputs). The address of the master PLC is set in parameter level PA7 (value range: 1 to 20); it must be different from the addresses of the additional controllers.

Functions

Default Configuration

In INF7 info level, all other TROVIS 5100 devices are listed with their controller type and LON address (e.g. “74-01“). If the display blinks, a fault occurred during communication.

7.1 Sending outdoor temperatures and the controller time

Two outdoor temperatures and the controller time can be made available on the LON bus to be adopted by the other controllers. Each controller in the system can send these values. The values are either sent by one controller or each values is transmitted by a separate controller.

The controller time and the outdoor temperature are transmitted every four minutes. In addi tion, the outdoor temperature is sent when it changed by 0.5 °C or more. All controllers delete the values received over the bus ten minutes after the last update.

EB 5171 EN 31

Transmitting the controller time

The controller time can be made available to all LON devices. They read the transmitted con troller time and adopt it. The controller time is sent using CO7 -> FB02 = ON. This function may only be activated in one LON device; otherwise, different controller times may be trans mitted.

In case the LON device sending the controller time fails, all other devices continue operation with their local time setting.

9 Electrical connection

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 convert-

ers, 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 appropri

ate surge or overvoltage protection measures are taken. Such measures are indispens able for bus lines! The shield of signal lines installed outside buildings must have current conducting capac

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

Noise suppression

The TROVIS 5171 Controller with SAMSON actuator is interference suppressed according to VDE 0875. If different actuator makes are used, or moreover, further actuators with interfer ence sources are used in a plant, the operator/supplier of a custom-made plant must make sure that the entire plant complies with VDE 0875 regulations due to the legal obligation of ensuring interference suppression.

EB 5171 EN 35

Electrical connection

Connecting the PLC

Open the housing to connect the cables. Make holes in the marked locations at the top, bot tom or back of the housing’s back panel and fit suitable grommets or screw joints. Observe the diagram on the following page for connection. The connection diagram con

tains all possible inputs and outputs. The assignment of the corresponding inputs and outputs is determined by the respective program.

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.

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 the outputs which then switch the elevated load. The 10 binary outputs (BA3 to BA12) can be loaded with max. 250 V AC, 2 A.

LON network (SAMSON’s own LON)

In devices with LON interface, the LON bus can be connected to terminals 1 and 2. The wiring has a reverse polarity protection, i.e. the two strands can be assigned to the terminals as you like.

LONMARK

The connection of LONMARK devices requires additional software. The devices are connected to terminals 1 and 2. On using LONMARK devices, the SAMSON LON is not available. In this case, CO7 -> FB00 = OFF must be configured.

Meter bus

The meter bus is connected to terminals 48, 49, and 50.

Terminal 48: Input signal Terminal 49: Neutral conductor Terminal 50: Voltage supply for heat meter, 15 V DC

(if required)

Modbus

The Modbus is connected over the RS-232 serial interface.

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.
