Warning! Dangerous electrical voltage!

Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally restarted.

• Verify isolation from the supply.

• Earth and short circuit.

• Cover or enclose neighbouring units that are live.

• Follow the engineering instructions (AWA) of the device concerned.

• Only suitably qualified personnel in accordance with EN 50110-1/-2 (VDE 0105 Part 100) may work on this device/system.

• Before installation and before touching the device ensure that you are free of electrostatic charge.

• The functional earth (FE) must be connected to the protective earth (PE) or to the potential equalisation. The system installer is responsible for implementing this connection.

• Connecting cables and signal lines should be installed so that inductive or capacitive interference do not impair the automation functions.

• Install automation devices and related operating elements in such a way that they are well protected against unintentional operation.

• Suitable safety hardware and software measures should be implemented for the I/O interface so that a line or wire breakage on the signal side does not result in undefined states in the automation devices.

• Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use power supply units complying with IEC 60364-4-41 (VDE 0100 Part 410) or HD 384.4.41 S2.

• Deviations of the mains voltage from the rated value must not exceed the tolerance limits given in the specifications, otherwise this may cause malfunction and dangerous operation.

• Emergency stop devices complying with IEC/EN 60204-1 must be effective in all operating modes of the automation devices. Unlatching the emergency-stop devices must not cause restart.

• Devices that are designed for mounting in housings or control cabinets must only be operated and controlled after they have been installed with the housing closed. Desktop or portable units must only be operated and controlled in enclosed housings.

Moeller GmbH

Safety instructions

• Measures should be taken to ensure the proper restart of programs interrupted after a voltage dip or failure. This should not cause dangerous operating states even for a short time. If necessary, emergencystop devices should be implemented.

• Wherever faults in the automation system may cause damage to persons or property, external measures must be implemented to ensure a safe operating state in the event of a fault or malfunction (for example, by means of separate limit switches, mechanical interlocks etc.).

Application field The S40-AM-TD application module, version 2.0, provides a

range of different function blocks. These function blocks form the interface between telecontrol modules and the user program in the PLC. They support the configuration of telecontrol stations that are interconnected via a dial-up line system. A telecontrol station consists of:

•PLC

• ZB4-501-TC1/-TC2 telecontrol module; only ZB4-501-TC1 telecontrol modules version 03 or higher can be used. It must also be remembered that this module can only be connected to PS4 controllers and that the address is permanently set to 2.

• Dial-up modem; The use of a wireless modem on the PS416-TCS-200 controller is not supported by the hardware and software.

All telecontrol stations have the same rights. This means that each station can establish a connection with another station via a dial-up modem. Normally data is collected from several remote stations in a central station and processed.

Depending on how the parameters are set, the stations can have the same performance capabilities and provide all services available. Alternatively, a station’s parameters can be set so that only basic services can be carried out.

2 Data Arrays of the Function Blocks

Data exchange principle Data is exchanged between stations via “byte” type data

arrays. This means that data formatted differently in the application must be converted prior to entry in the data array. Conversely, array elements must be converted to the data format of the application before they can be read. The following example illustrates data exchange between a station and two remote partner stations. The “TCMT1zU2/U5“ function blocks provide all functions, whilst the “TCMT1zB0“ function block only provides the basic service “Send/Read Fixed Length Data”.

The “z” in the function block designation is the placeholder for either a = asynchronous or b = synchronous.

02/02 AWB27-1300-GB

Data array size

Data array size The size of the data arrays depends on the function block

type selected: If the “TCMT1zB0“ or “TCMT1zU0“ function blocks are

selected, the data array is one-dimensional and is 1 to 220 bytes for send and receive data (a fig. 3).

The data arrays in function blocks “TCMT1zU2“ and “U5“ are three-dimensional. These are defined by using the parameters subaddress (0 to 255) and “offset address” (0 to

219) of type UINT (a fig. 4). The third parameter specifies the number of remote partner stations.

Separate data arrays are defined for all send and receive data. In the example, the 256 send data arrays and 256 receive data arrays would be for the central station and one send and receive data array for each of the 256 partner stations. Ensure that the size of the send data array in the central station is the same as the size of the receive data array in the partner station and vice versa. In the example therefore, the number of SD central station must be the same as the number of RD

send data units from the

receive data units of the partner station. The maximum size of all data arrays in a station is approx.

6.5 Kbyte for PS4-150/-200 and 13 Kbyte for a PS4-300/ PS416. In a central station this available range must be shared equally amongst all other stations of the telecontrol line.

Data Arrays of the Function Blocks

02/02 AWB27-1300-GB

With a PS416 or PS4-300 controller as the central station, the maximum available range (send and receive data arrays) is therefore calculated as follows:

Maximum data volume per partner station =

When assigning offset addresses and subaddresses, make sure that the maximum available data volume is not exceeded.

Offset addresses x Subaddresses (send data array) + Offset addresses x Subaddresses (receive data array) = Data volume F Maximum data volume per partner station

Assigning the data array parameters

Default parameters

The function blocks are supplied with default parameters for a data transfer of 20 bytes of send and receive data.

These data arrays are already set up in the variable declaration of the function blocks. They may have to be adjusted, however, if the default parameters are not exactly as required.

One-dimensional data arrays for TCMT1zB0/U0

The function blocks have the following data array basic settings and range limits:

1) Tra_sub_max/Rec_sub_max: No subaddress is required as the data arrays are onedimensional. With variable length frames, the data entered instead of the subaddress and offset address is transferred transparently. This can be used on the partner station to check the Subaddress value. If, for example, the sent “Subaddress” value is less than the set address of the partner station, this station will send a negative acknowledgement.

2) Tra_dfl_max/Rec_dfl_max: Both parameters have default value 220, which can be adjusted accordingly for the application concerned. The values for “Tra_dfl_max/Rec_dfl_max” must be the same as the number of offset addresses of the array “tra_dat/rec_dat”! Example: Tra_dfl_max = 220 => tra_dat = 0 to 219

3) Fixed_length: If service 17 is executed (send/read fixed length RAM data), parameters xxx_dfl_max must f fixed_length.

5) Rec_dfl_max: The maximum offset address of all receive data arrays “rec_dat” must be entered for “rec_dfl_max”.

6) Fixed_length: Data length of a fixed length frame (service 17). If service 17 is executed (send/read fixed length RAM data), parameters xxx_dfl_max must f fixed_length.

The following shows which parameters can be adapted.

Assigning the data array parameters

Changing parameters

The set data array parameters can be modified in the following way:

XSave the function block under another name. XChange the desired parameters in the variables

declaration.

XCheck your changes by checking syntax using (ALT+F10).

The modified function block is available for further use in the list of application-specific function blocks.

Examples

Two remote partner stations are connected to a central station via a dial-up modem. The partner stations only communicate via the central station. The central station sends 5 bytes to the partner stations (service 12) and receives 30 bytes from them (service 15). To do this, the following settings must be made in the variables declarations of the central and partner stations:

Central station

The function block “TCMT1zU2“ is used for the central station. The above-mentioned parameters result in a 70 byte data memory requirement.

Working with data arrays

Working with data arrays The next section describes how to read or write data arrays

using the example of the send and receive data arrays of a central station.

Ensure that all the array indices (subscripts) are within the limits when accessing data arrays. If the array index (subscript) limits are exceeded, the controller will “Halt“ and the “Not-Ready“-LED will light up.

The data arrays were defined as follows in the variables declaration for the parameter function block:

VAR_INPUT

tra_dat: ARRAY[1..2, 0..0, 0..29] OF BYTE ; (*Send data array (station number,

subaddresses, offset addresses)*)

END_VAR

VAR_OUTPUT

rec_dat: ARRAY[1..2, 0..0, 0..4] OF BYTE ; (*Receive data array (station number,

subaddresses, offset addresses)*)

END_VAR

Writing data array elements (in the user program)

To save the constant “5” in the array element [station “2”, subaddress “0”, offset address “3”] of the send data array, proceed as follows:

LD 5 ST Instance_name.tra_dat [2,0,3] . . END_PROGRAM

Data Arrays of the Function Blocks

02/02 AWB27-1300-GB

Reading data array elements (in the user program)

The content of the station “2”, subaddress “0” and offset address “3” array element of the receive data array is stored under the variable “VALUE_1”.

VAR

VALUE_1 : USINT ; END_VAR . . LD Instance_name.rec_dat [2,0,3] BYTE_TO_USINT ST VALUE_1 : . . END_PROGRAM

Data array access for fixed-length frames

When data is transmitted using fixed length frames, only the data array range for subaddress “0” is defined. The data is read and written under the parameter “fixed_length”, starting with “tra_source_offset” = 0 up to the maximum length.

Data array access for variable length frames

All the elements of the data array can be accessed with variable length frames. The subaddress “tra_ subaddress”, offset address “tra_source_offset” and/or “tra_destination_offset” and user data length “tra_variable_length” function block inputs can be used to access any elements of a subaddress, from one byte up to the entire data array length.

02/02 AWB27-1300-GB

Working with data arrays

Transferring status information

“User_status” bits are used to transfer up to four bits of information and are transferred with every service. If status changes are detected at the function block inputs “user_status_1” to “user_status_4” of the telecontrol station concerned while a service is being processed, the inputs will be automatically updated in the array of “user_status” bits at the partner station.

“User_status” bits can be used to transfer bit data, such as battery monitoring (DBM) to the partner station without the need for a separate service.

3 Function Blocks

Overview The function blocks of the S40-AM-TD application module

make it easier to program the data transfer between the PLC and telecontrol modules.

Three types of function blocks are provided:

• Dial-up function block

• Telecontrol function block

• Parameter function block

The dial-up function block performs the following functions:

• Modem initialisation

• Establishment and clearing of the connection to partner station

• Connection monitoring

• Redial within the set time frame

• Display of modem signals

The telecontrol function block carries out the communi- cation services and monitors the execution of a service.

The parameter function block is used to declare the dialup and telecontrol function block and contains the calls for these function blocks. The dial-up and telecontrol function blocks cannot be processed directly. Their parameters are set via the parameter function block. Dial-up and telecontrol function blocks are provided in the form of a LIB file.

Depending on the capabilities of the PLCs, there are several parameter and telecontrol function blocks that are matched to each other. These parameter and telecontrol function blocks vary according to the number of services and partner stations they support. The dial-up function block is the same for all.

The function blocks with basic services enable a connection for sending and reading data between two stations.

Selecting the function blocks

Install both the parameter function blocks in the form of a POU file (.POE) as well as the library file (.LIB) containing the dial-up and telecontrol function blocks. A library file is provided for every PLC type. After installation no other measures are required for the library files.

Example

For example, to incorporate a universal function block with four communication channels for a PS4-300 in synchronous mode with the ZB4-501-TC2 telecontrol module, the following programs in the table must be installed:

• FB file: TCMT1zU2.POE

• Library file: TCM_TD_3.LIB

After the installation you can integrate the function blocks in your user program (a page 30). Remember that it must be called in each program cycle.

Code/data size, cycle time requirements

The specifications apply to the example programs with the default data array sizes in a passive state. With an active data channel this time requirement will change according to the service concerned and can therefore only be determined in the overall application.

Initialisation string

Modem parameters are adapted to the telecontrol application by sending an initialisation string to the modem after switching on the controller or after a “Reset“.

The initialisation parameters for several modems are defined in the “init_parameter” array. If only one modem is used, just enter the element for this modem in the array. It must, however, be ensured that the code 0-6 is entered accordingly in the “b_ar_modulparameter[1]” array. This is particularly important for GSM modems with the codes 4 to

6. The unused arrays can be used for tests with the modem. The initialisation string is sent automatically after a module is reset. “AT” as header and “crlf” (carriage return line feed) at the end are generated automatically by the module.

The RTS control line of modems with the codes 4, 5 and 6 is automatically set to “1“.

Function Blocks

Communication between all modem types is only possible if the ISDN modem with an integrated analog section is used. With modems that are solely ISDN modems, the communication partner must be run in V110 mode. Only GSM modems are suitable for this. The initialisation required is shown in table 4 for type 6.

All tested modems can be used with their factory setting if they are set for 9600 baud 8N1. The following modems must be initialised with the following parameters via a terminal program such as Windows Hyperterminal:

• Westermo TD-32 AT&FC1&K0&Y0S0=1X3&W0 crlf

• Siemens M20T AT+IPR=9600CR

code

BOOL The outputs indicate the communication between the module

and the modem (initialisation, dialling). A call from the communication partner is not indicated. This event can be detected on the “message” output (RING code = 2) and on the

“busy” output (= 1). BOOL Connection is established. BOOL 1. On dialling:

After signal “1“ has been set on the “dial” input, “dial_busy”

shows “1“ until the connection has been cleared. The reset to

“0“ after the connection has been cleared can be delayed via

“dial_wait_repeat”.

In this way a dial attempt can be prevented or delayed if:

– the communication partner is calling or

– a subsequent station is dialled locally and the country wait

time in the modem has not yet elapsed in the modem (possible error “DELAYED CALL“ or “BLACK LISTED“).

2. Incoming call

BOOL The output is set if a connection cannot be established after the

specified number of attempts. If the “dial_repeat” input is set

to “0”, the “alarm” function block output is only triggered on

error code H2F.

It is reset on “reset”, “dial” = 0, or when a connection has

been established. STRING Status messages in plain text a page 43. TIME Remaining time till the next connection attempt. USINT a table 8 on page 43

They are assigned with default parameters so that a safe operation is possible with all tested modems. Depending on the type of use, it may be necessary to adjust the time parameters.

When using GSM modems the data format must be set to “8N1”. In order to reach the required level of data transmission security with long frames, the frame format must be set to “FT3“. For this the “telegrammformat” input on the parameter function block must be set to “1“.

parameters that specify the response time of the station. The parameter “Device_type” is used to determine whether it is a fast (Device_type = 0) or slow (Device_type = 1) responding station. “Time_delay_short” and “Time_delay_long” are parameters that must be specified for each station. If a station is assigned “Device_type” = 0, it will respond with a delay time defined in “Time_delay_short”. “Device_type” = 1 is assigned accordingly to “Time_delay_long”.

If the PS416 is fast, it is only processing short frames with a fast cycle time. A PS4-200 is always classified as a slow PLC.

After connection establishment, station A (e.g. PS416, fast) will signal its “Device_type” = 1. In response, station B (e.g. PS4-200, slow) will signal its “Device_type” = 0. Station A will then respond to every frame from station B with the delay time specified at “Time_delay_short” (e.g. 300 ms), B will respond with a 600 ms delay.

The parameters “Time_rts_delay_off”, “Time_gap_time” and “Time_cts_timeout” are only transferred at cold starts/ warm starts or when the module is reset.

Telecontrol function block services

After connection has been established between the stations, the telecontrol function blocks provide the services for data exchange between the individual telecontrol stations. They are activated by relaying the corresponding code to the “command” input of the parameter function block and via a signal at the “strobe” input.

Service 20: Read PLC clock – partner station

When performing this service, the clock data for station B, increased by the “time_adjust” value, is relayed to station A and output at the “rec_clock” function block output of station A.

Use it in conjunction with the function block “lock_time” input and you can define whether station A clock time is to be synchronised.

“lock_time” = 1:Read PLC clock station B

The clock data of station B is increased by the “time_adjust” value (of station A) and applied to the “rec_clock” function block output of station A.

Service 30: Remote reset

This service can be activated only in those stations in which the “station_type” function block input has the value 1. At the same time, the partner station must be allocated a parameter value of 0. If these conditions are fulfilled, the partner station will have basic status (basic status: error counters and frame sequence bit are reset).

Service 31: Read Status

When service 31 is executed, the parameters and error counters of station B are transferred to station A where they are stored in the “rec_status_array” array.

4 Operating Behaviour

Startup behaviour After a controller warm start or cold start, or after a function

block reset, the interface parameters are relayed from the PLC to the module. Should the parameters contain incorrect settings (e.g. invalid transmission rate of 610 baud), the default parameters are adopted and an error message is generated (a also “Error Codes” on page 67).

Table 12: Default interface parameters with dial-up line

Baud rate Start bit

(fixed value)

9600 1 8 None 1

If the interface parameters have been transferred to the module, the modem is initialised with a time delay that was set in the “rts_delay_init” (GSM) parameter. The module and the modem are then ready for operation (modem code = 0).

Data bit Parity bit Stop bit

Further information on the startup behaviour is given in the relevant telecontrol hardware manuals (AWBs), in the chapter “Operation”.

Operating Behaviour

02/02 AWB27-1300-GB

Connection establishment After each connection has been made, the active station

checks whether an identical “com_ref_n” communication reference has been entered at the partner station. Service 31 Read Status is automatically started for this purpose. Once a connection has been established and the stations have been identified, the “ready” function block output indicates that the telecontrol services can now be started.

If the identification is negative, the partner station acknowledges this and indicates error code “40h“; no services can then be transmitted.

Data communication between the “tra_dat” and “rec_dat” now takes place in the range for which a valid communication reference has been found.

Password There are two ways of protecting a station against

unauthorised access:

Communication reference

Once a connection has been established, the stations automatically check via the dial-up function blocks, whether identical “com_ref_n” communication references have been entered for the communication relation. A UINT is provided for the value range (1 to 65535). Non-matching communication references generate an error message.

Therefore only those stations sending a communication reference with a corresponding reference for “com_ref_n” FB inputs of the partner station can communicate with one another.

02/02 AWB27-1300-GB

Password

Service 33 – Send information string

Each telecontrol station can protect itself against unauthorised access by other stations via the “lock_station” function block input. In these circumstances, all incoming services other than service 33 are rejected.

Example: Station A operates as central station and station B as the

partner station. Station B has protected itself from access by other stations via the “lock_station” FB input. The password of station B is “Model_station”.

After connection has been successfully established via station A with the dial-up function block, the station sends the text string “Model_station” (tra_information:=´Model_station´) to station B using the service 33. The text string is indicated there at the telecontrol function block output “rec_information” (Model_station:=rec_information).

The text string received is then compared with an internal password and, if it matches, the “lock_station” function block input is reset. Station A can now exchange all available services with station B.

If the connection between the stations is cleared, the content of the “rec_information” function block output (empty string) is set and the “lock_station” function is reactivated.

Operating Behaviour

02/02 AWB27-1300-GB

You must activate service 33 in the controlling station via the user program. At the outstation, you must observe the following program steps. You must also make any appropriate entries in the variables declaration.

Configurations of telecontrol stations consisting of stations with equal rights are referred to as symmetrical configurations. The stations in these configurations combine the properties of primary and secondary stations.

Telecontrol

Telecontrol is the monitoring and controlling of processes distributed over a wide area by means of coded bit-serial data transmission.

Telecontrol configuration

The combination of telecontrol stations and transmission paths between stations.

Telecontrol station

Central station or outstation in a telecontrol system.

Telecontrol system

A telecontrol system is used to control and monitor processes that are distributed over a wide area. The system consists of all devices and functions for data acquisition, processing, transmission and display of the necessary process information.
