Communication by Modbus allows data to be exchanged between all devices connected to the bus. Modbus is a protocol which creates a hierarchical structure

(one master and several slaves).

z z

The master manages all exchanges according to two types of dialog: the master exchanges data with the slave and awaits a response, the master exchanges data with all slaves and does not await a response

(general broadcast).

This communication type is available for z Premium PLCs through: z z a PCMCIA TSX SCP 111 card associated with the RS232 physical layer, a PCMCIA TSX SCP 112 card associated with 20 mA current loops, z z a PCMCIA TSX SCP 114 card associated with RS422 and RS485 physical layers, a Built-in Link with a TSX SCY 11601/21600 / 21601 module associated with the RS485 physical layer.

z z z

Version V3.3 Micro is configured in slave mode through the terminal port associated with the RS485 physical layer.

Version V5.0 micro is configured in master mode (TSX 37-10/21/22 only) or in slave mode through the terminal port associated with the RS485 physical layer.

The micro supports the PCMCIA cards described above.

The maximum frame size is 256 bytes.

PCMCIA cards and the TSX SCY 11601/21600 / 21601 module's built-in link can process 8 communication functions at once in Modbus master mode.

Modbus master mode is only available on the Terminal Port from version V4.2 of the

PL7 software. It is not possible to download a Modbus master configured application to a Micro of version V5.0 or below.

The PL7 program's MAST task can, in Modbus master mode, process up to 4 communication functions at once via the Terminal Port. In addition, an error code is sent.

The READ_VAR communication function can read up to 1000 consecutive bits in any remote device. To read more than 1000 bits, the SEND_REQ communication function must be used.

Note: Nano, Micro and Premium PLCs cannot send more than 1000 bits after a read request.

Memory addressing

The READ_VAR and WRITE_VAR functions are used to read and write objects contained in series 1000 PLCs. These include words, double words, floating points and character strings.

The address of the object in the series 1000 PLC memory determines the type of the object to be accessed.

Programming rules

When you wish to access the objects of a series 1000 PLC, the index of the first object to read (or write) is the access address.

Example: z Read %M0 bit z

READ_VAR(ADR#0.1.3, ‘%M’, 16#A000 , 1, ...)

Read word %MD25000

READ_VAR(ADR#0.1.3, ‘%MW’, 16#61A8 , 2, ...)

Moreover, these communication functions cannot be used to exchange double words or character strings via the Modbus protocol. If needed, it is possible to perform the transfer in %MW form, the application must determine the direction in which the words are stored .

The diagnostics functions can be accessed via the SEND_REQ function.

After applying voltage, the module carries out auto-tests. Display indicators flash during this phase.

If there is no PL7 application in the PLC, the module awaits configuration.

If there is a PL7 application in the PLC, the application's configuration is transmitted to the module, and then the module starts up.

When there is a power outage, the PLC procesor carries out a hot restart. The module then restarts its auto-test procedures.

ASCII mode: z z the characters are coded on 7 bits, the start delimiter is detected by receiving the characters ":" or by a silence longer than the delay between characters.

The end delimiter is detected by a CR and LF (carriage return and line feed) or by a silence longer than the delay between characters.

Note: The value 1000 in ASCII mode corresponds to an infinite delay between characters.

The window looks like this:

Stop

1 bit

2 bits

The Stop field is used to enter the number of stop bits used to communicate on

Modbus. The possible values are 1 or 2 stop bits. This field is to be configured as a function of the other devices.

Note: The default value is 1 stop bit.

The window looks like this:

Parity

Even Odd None

This field is used to define whether or not a parity bit is to be added, and, if so , what its type will be. The possible values are Even, Odd or none (Even by default). This field is to be configured as a function of the other devices.

Modbus configuration

RTS / CTS Delay The window looks like this:

RTS / CTS Delay

1 X100 ms

Data Carrier

(DCD)

Before sending a character string, the module activates the RTS (Request To Send) signal and waits for the CTS (Clear To Send) signal to be activated.

This allows you to enter: z the maximum waiting time between the two signals. If this time expires, the request is not sent to the bus. z the value is expressed in hundredths of milliseconds, z z z z the default value is 0 ms, the value must be between 0 s and 10 s, the value 0 specifies that there is no management of the delay between the two signals.

carrier management (DCD signal, Data Carrier Detected) is only used when communicating with a controlled carrier modem: z z if this option is selected, characters can only be received if the DCD carrier signal has been detected, if this option is not selected, all characters received are taken into account.

Using the SEND_REQ communication function

At a Glance The UNI-TE Action-object request (request code 16#9F) is used to transmit all

Modbus (See : PL7 Micro/Junior/Pro ; Communication applications ; Volume 1) functions.

After executing this request, the report is always 16#CF00 .

To check the exchange, it is also necessary to test the content of the first word in the reception table.

Possible values of the first word: z z

0: indicates that the exchange has been performed,

1: indicates that the exchange has not been performed,

The transmission buffer should contain the following information: z z z z z z first word: z Byte 0: function code, z Byte 1: sub-function code, second word: Modbus function identifier, which is always 16#0296 third word = 0: reserved fourth word: Modbus function parameters fifth word: Modbus function parameters n th word: Modbus function parameters

Note: this function is not available in Modbus master mode on the Terminal port.

Principles of communication between two stations

Introduction The call direction is from station A to station B:

Operation

Station A station where call is to be made (transmitter)

Switched telephone network

Station B called station

(receiver)

The following table describes the different stages of communication between two stations:

Phase

Description

While idle, all modems are by default awaiting a possible connection request.

Station A sends a call request to number X on station B using AT commands

(or using the CALL_MODEM communication function in the case of a PLC).

An exchange procedure between the modems results in the line being established point by point between station A and station B. Connection is established if the correct password is used (if password management is employed).

Stations A and B then dialog according to the protocol chosen on calling, whether Uni-telway or character mode. Communication is carried out using the standard communication functions. Each station can initiate exchanges.

In Uni-telway mode, by default, the calling station is the slave and the station called is the master. To ensure compatibility with existing applications, it is possible to set the parameters of the CALL_MODEM communication function so that the local station remains in master Uni-telway mode.

Station A sends a request for disconnection to its local modem.

Stations A and B return to their initial state, and are able to initiate another call.

Hardware Compatibility

About PLCs This type of communication is available for PLCs that are at least version V3.3.

z z

Premium via the PMMCIA TSX MDM 10 card,

Micro accepting the PCMCIA described below.

The card can also be inserted in PCs that have type 3 PCMCIA card slots.

Note: for certain types of CPU, it is recommended that a PCMCIA memory card

( CALL_MODEM communication function occupying 25 Kb of program memory space) is used.

Networks and

Devices

The TSX MDM 10 communication card only connects to the STN - (Switched

Telephonic Network).

It cannot be connected: z z z to specialized links, to NNIS (Numerical Network for Integrating Services) networks, to the GSM (Global System for Mobile) network.

Third-party modem compatibility is guaranteed for modems that are designed for

COM 1 switched telephonic network. See Communication between PLCs using an

external modem, p. 83 .

35013154.02 07/2208

General

About Protocols The TSX MDM 10 card supports the two character formats 10 or 11 bits.

For 11 bit communication between modems, compatibility is only guaranteed with modems designed for the COM 1 telephone network.

The TSX MDM 10 is incompatible with configured third-party modems: z z with parity, with data compression and error correction.

In ASCII, the TSX MDM 10 card allows: z z in called mode: z z transmission of data coded on 7 bits reception of data coded on 8 bits.

in calling mode: z transmission of data coded on 7 or 8 bits, z reception of data coded on 7 or 8 bits.

35013154.02 07/2208

General

Software compatibility

X-WAY transparency

Transmission

The modem card provides X-WAY transparency, and supports two types of protocol: z z

Uni-telway master or slave protocol, character mode protocol.

When a local network station communicates with a remote station on the switched telephone network, the calling station must be in master mode, and the called station in slave mode.

The speed of transmission varies between 4800 bits/s and 9600 bits/s. The size of the frames sent is 256 bytes in total (240 bytes usable in Uni-telway mode, and 200 bytes in character mode).

Only one communication function can be active at a time on the TSX MDM 10 card.

The application must manage line disconnection. Only the station which initiated connection using External CALL_MODEM (see External CALL_MODEM function,

p. 71 ) has the right to disconnect the line.

The CALL_MODEM communication function ensures disconnection.

The TSX MDM 10 card defines a set operation for the INPUT_CHAR instruction.

When the INPUT_CHAR function is activated, the frame end character must be received before the end of the task cycle.

If several cycles are needed to receive this character, the character string is lost.

35013154.02 07/2208

General

The application Modem configuration requires PL7 software from version V3.3 onwards.

CAUTION

Downloading the application

The modem card cannot be used to up- or download a PL7 application.

If loading is initiated by mistake, a failure message will appear on connection and the PLC application will be lost.

However, it is always possible to load an application via the terminal port.

Failure to follow these instructions can result in injury or equipment damage.

The station called can recognize a maximum of 8 calling stations for Micro PLCs, and 16 for Premium PLCs where the password service is used. Only the

TSX MDM 10 card ensures the management of passwords. For third party devices, passwords are managed according to the coding protocol for password exchanges.

Coding of exchanges, p. 107 .

Introduction

Station password

Call parameters

Dial mode z z z z

They are split into two parts: a Station password field a Call parameters window a Dial mode window a Connection parameters window

Each station has its own password. It is used to identify the station. During a connection request, the calling station sends its password so that the called station can identify it and then authorize the connection.

For communication with other devices, the exchange protocol, described in exchange coding (See

Coding of exchanges, p. 107

), must be supported by the remote device.

These include all the parameters necessary in order to make a call: z Dialing time seconds.

(60 seconds by default): corresponds to the duration of a call in z Delay between calls (60 seconds by default): corresponds to the calling station waiting time, in seconds, between two connection attempts. If a connection attempt fails, the PLC attempts another call after the waiting time if the number of redials has not been exceeded.

z Number of redial attempts (3 redial attempts by default): is used to set the number of call attempts in the event of failed connection attempts. If the last call fails, the CALL_MODEM function, which launched the connection attempts, sends back an error report. If the number of redial attempts configured is 0, no redial attempts will be made.

z z

The dial modes are: either tone dial, or dialing.

35013154.02 07/2008

Connection parameters

Modem configuration

These include all the necessary parameters for a connection: z Maximum connection time (0 seconds by default): z is used to define the connection time in seconds. After this time has elapsed, the current connection will be stopped. This control is necessary if the sender z station is not able to disconnect from the line following an application error switching to STOP, or a system error.

z if the number of redial attempts configured is 0, this control will not be active.

Maximum time between two frames (0 seconds by default): z z if the time between two frames (in seconds) is greater than this maximum time, the connection will be broken off. This control is necessary in the event of an unused connection.

if the configured value is equal to 0 or greater than 360 seconds, communication will be broken off after 360 seconds.

CALL_MODEM communication function

Introduction

Syntax

The CALL_MODEM communication function is used to manage connection with the

TSX MDM 10 card.

z z

It provides the option to: z connect a line between a TSX MDM 10 card and another TSX MDM 10 card, or a remote third party modem, z disconnect a line which has been established or is in the process of being established, reset the TSX MDM 10 card if necessary (following a protocol error, for example), send AT commands.

The syntax of the CALL_MODEM communication function is presented in the following format:

CALL_MODEM (ADR#0.1.SYS, 1, %MB100:20, 0, 0, %MW256:4)

The following table describes the different parameters of the function:

Modem specific management parameters

Introduction A detailed description of these parameters is available in the common section. See

(PL7 Micro/Junior/Pro ; Communication applications ; Volume 1).

This document only describes parameters specific to communication via a modem.

z z

These parameters are:

Timeout, operation report.

CALL_MODEM function timeout

Timeout of the function is a time used to check for the absence of response to the

CALL_MODEM function.

This time, (increment of a 100 ms time base), is a combination of different parameters configured via the Modem Configuration screen.

It is advisable to allocate the following minimum value to this parameter:

Minimum timeout = the number of redial attempts * dialing time + (number of redial attempts - 1) * delay between redial attempts

Operation report Operation reports are specific to the modem and only significant if the z z communication report has the following values:

16#00,

Coding of exchanges

At a Glance

Format of the string

When a connection request is made, a 32-byte character string may be sent on the line by the calling station to initialize the connection.

z z z z z z z

The character string which may be sent on the line is in the following format: the Start of the frame field, of 2 bytes in length, containing the value 16#531B, the Password field, of 8 bytes in length, containing the value of the station z password (8 characters), the Type field, (protocol type) of 1 byte in length, containing 16#00 for Uni-telway z mode or 16#01 for ASCII mode, the UTW field, (Unitelway mode) of 1 byte in length, containing 16#00 for a master or 16#01 for a slave, the Slave address field, with the slave address stated in 1 byte , the Number of slaves

in length, containing the value 16#451B, z z

Note: This coding of this string depends on the following parameters:

Station password of the modem configuration screen,

Mode and Options of the communication function.

The "Checksum" is performed over 1 byte, without taking into consideration the value of the most significant byte.

Note: The password must not exceed 8 characters in length .

Modem Programming

Processing of the string

The following table lists different processing scenarios:

Calling station (TSX MDM 10) z z if the station is configured by default, the modem transmits no character string on the line: z connection without password ( CALL_MODEM z function with option 4),

Slave Uni-telway protocol with addresses Ad0 = 1 and Ad1 = 2.

in all other scenarios, the station sends the character string.

Station called (TSX MDM 10)

Scenario where password management is not configured z the station waits for 5 seconds. If no character string has been received on the line, it switches to Uni-telway master mode and scans the slave addresses Ad0 = 1 z and Ad1 = 2, otherwise the station tests the Password field equal to

FFFFFFFF in hexadecimal: z if the test is valid, the station tests the Type, Mode z and Number of addresses fields, and switches to the corresponding mode.

If the test is invalid, the line is closed.

Scenario where password management is configured z the station tests the received password: z if the password received does not correspond to any password in the list, the line is closed.

z if the test is valid, the station tests the Type, Mode and Number of addresses fields, and switches to the corresponding mode.

A/ - Command re-execution

Introduction The modem behaves as though the last command line had been returned by the

DTE. "A/" repeats all the commands contained in the command buffer.

The principal use of this command is to be able to renew a call (using the dial command) which has not finished following an engaged signal or no reply. This command must appear alone on the command line and must finish with the character "/". It must not finish with a carriage return.

Dn - Dialing

Introduction This command asks the modem to unhook, to dial the number corresponding to the dialing string entered and to attempt to establish a connection. In the absence of a dialing string, the modem unhooks and attempts to make contact in send mode.

Dialing Modifiers The valid parameters for the dialing string are described in the following table: For reasons of clarity, it is possible to use certain punctuation symbols such as brackets, hyphens or spaces. These symbols are not processed by the command.

Code

0 - 9

A - D

S = n

Description

Numbers 0 to 9 in MFDT

The "asterisk" symbol (tone dialing only)

The "hash" symbol (tone dialing only)

Letters A, B, C and D in MFDT. In certain countries, these letters cannot be sent during dialing.

Redial the last number: the modem redials the last valid telephone number.

The L must come immediately after the D and all subsequent characters are ignored.

Selects pulse dialing: pulse dialing dials the numbers which follow until a 'T' is reached. This applies to current and subsequent dialing. In certain countries, the dialing mode cannot be changed once the first number has been dialed.

Selects tone dialing: tone dialing dials the numbers which follow until a 'P' is reached. This applies to current and subsequent dialing. In certain countries, the dialing mode cannot be changed once the first number has been dialed.

This command will be accepted but it will have no effect.

Dialing of number stored in directory (n = 0 to 19) (see command &Z).

Quick hang up: the modem hangs up during the period defined by the value of

S29. In certain countries, a limit may be imposed on this period.

Waiting for tone: the modem waits for the tone before dialing the digits which come after the 'W'.

Waiting for silence: the modem waits until there are at least 5 seconds of silence in the call frequency band before dialing the dialing string. If the modem does not detect these 5 seconds of silence after a period defined by the call abandon timer (S7), the modem ends the call attempt with a NO ANSWER message. If the detection of an engaged line is validated, the modem can end the call with the result code BUSY. If the answer tone comes while this parameter is being carried out, the modem makes contact.

Dialing pause: the modem pauses for the period indicated by S8 before dialing the digits which come after the ','.

Code Description

;

Returns to command mode. Added to the end of the dialing string, this parameter returns the modem to command mode once it has processed the part of the string which precedes ','. This enables new AT commands to be sent while off-hook. The new AT commands can be set on the source command line after ',' or entered on new command lines. The modem does not attempt to establish the connection until the new dial command is sent without the end symbol ','. Use 'H' to abandon dialing in progress and hang up.

Switch call tone: only applies to the dialing attempt in progress.

Ignored: can be used to format the dialing string.

( )

Ignored: can be used to format the dialing string.

<space> Ignored: can be used to format the dialing string.

Nn - Activation of automatic mode.

Introduction

Parameters

This command activates or deactivates detection of automatic mode. The parameter value, if valid, is written in bit 1 of S31.

The parameters are:

Code

Description

Detection of automatic mode is deactivated (equivalent to giving the 0 value to the sub-parameter +MS). The handshaking which follows is made according to the content of S37 or, if S37 is at 0, according to the most recently detected

DTE baud rate.

Detection of automatic mode is activated (equivalent to giving the value 1 to the sub-parameter +MS). The handshaking which follows is made according to the automatic mode algorithm supported by the modem, in other words according to the content of S37 or, if S37 is 0, by starting at 28800 b/s V.34 (RC288). This command also equates to F0 (RC144) (default value).

Result codes

Observations

The following table lists the possible command responses.

Code

ERROR

Description n = 0 to 1.

If n is not in the range 0 to 1.

The Nn and S37=x commands have priority over the values of the +MS command. When the N0 or N1 command is sent, the sub-parameters of +MS are updated to reflect the values of Nn and S37 (see descriptions of the +MS command and of the S37 register).

For example: z N1S37=10 updates the sub-parameters of the +MS command as follows: z

+MS=10,1,300,12000

N037=10 updates the sub-parameters of the +MS command as follows:

+MS=10,0,12000,12000

It is recommended to use the +MS command rather than the Nn and S37=x commands. The Nn and S37=x commands are supported to ensure compatibility with the existing communication software.

Introduction

Parameters

This command determines the way in which the modem sets in on-line data mode.

If the modem is in the on-line command mode, this command sets it in on-line data mode with or without a resynchronization attempt.

If the modem is in off-line command mode (no connection), ERROR is displayed as the response.

The parameters are:

Code

Description

Switches to on-line data mode without resynchronization attempt. The processing is determined by the call establishment task. In general, if there is a connection, this command reconnects the DTE to the remote modem after an escape (+++).

In STN mode only; switches to on-line data mode after a resynchronization attempt.

Result codes The following table lists the possible command responses.

Sn - S register read / write

Introduction

Parameters

The modem selects an S register, performs a read or write operation on an S register or reports the value of an S register.

The parameters are:

Code n n = v n?

Description

Sets the S register as the default register.

Attributes the value v to the S register n.

Indicates the value of the register S n. The n parameter can be omitted, in which case it is the value of S0 which is read. S can be omitted, in which case it is the value of the last consulted S register (default register) which is read.

Examples

Result codes z z z z

ATS7 sets S7 as the default register.

ATS38 sets S38 as the default register.

AT=40 gives the default register the value of 40.

ATS=20 gives the value 20 to S0.

If the number n is outside the range of available S registers, the modem sends back an ERROR message. The value 'v' is rollover 256. If the result is outside the permitted range for a given S register, the values are still stored but from a functional point of view, it is the upper and lower limits which are used.

The input and output values are always in decimal format. Note that some S registers are read-only. In these cases, a write operation to an S register appears to be accepted but the value is in fact not written.

T - Default adjustment of tone dialing

Introduction

Result codes

This command imposes MFDT dialing until the next 'P' dialing modifier or the next

'P' command is received. The modem sets an S register bit to '1' to indicate that all subsequent dialing will be tone dialing. Note that the DP command has priority over this command. It clears bit 5 of S14. In certain countries, this command may not be used (see P command).

Modus Plus communication: General

Introduction

Introduction Modbus Plus communication is used to exchange data between all devices connected by the bus.

The Modbus Plus protocol is based on the principle of a logical token bus (Logical

Token passing). Each station of one network is identified by an address between 1 and 64 and each station accesses the network after reception of a token. Duplicated addresses are not valid.

Network example

Modbus Plus

2 12

Premium Quantum

Token bus (logic ring)

Associated manuals

A Modbus Plus communication channel comprises three main functions: z point to point data exchanges via the messaging service, using the Modbus z protocol, broadcast exchanges of global data between all the stations participating in this z exchange, multidrop exchanges of specific data via the Peer Cop services.

If you require further information you should consult the following manuals:

Compatibility

Hardware

Software z z

This type of communication is available for PLCs of at least version V3.0:

Premium via the intermediary of the TSX MBP100 PCMCIA card,

Micro accepting the PCMCIA card described below.

Note: This type of communication is not available with TSX SCY 21601 modules.

Premium and Micro PLCs do not support redundancy with the TSX MBP 100 card.

The PCMCIA TSX MBP 100 card can process 4 communication functions at the same time.

The maximum size of the number of objects per communication function is 125 useful data words (maximum frame of 256 bytes).

In the event of communication of a Premium and Micro PLC with a Quantum PLC, it is necessary to shift addressing. To access a Quantum object with address n, the communication function on the Premium side must have the address n-1.

The Peer Cop service is only supported by Premium PLCs.

During configuration of inputs and outputs for the Peer Cop service, it is possible to allocate up to 32 internal words to each connection point in the local bus. The total number of words must not exceed 500 internal words.

Modus Plus communication: General

Integration into an X-WAY architecture

Introduction A Modbus Plus segment can be integrated into an X-WAY network architecture.

Communications between stations on the different networks are possible under certain conditions of use.

Communication to a Modbus Plus network

A client application connected to a FIPWAY or ETHERNET TCP/IP network can communicate with a Modbus Plus station via the Modbus protocol.

In this case, you must indicate the X-WAY network address of the Premium PLC which is connected on the Modbus Plus segment as well as on the FIPWAY network, and the number of the destination Modbus Plus station.

The syntax is as follows:

{network number, station number} 0.1. Modbus Plus station number

190

35013154.02 07/2008

Example

Modus Plus communication: General

In this example, the FIPWAY station {5.3} has a Modbus Plus connection and therefore, any remote FIPWAY station which wishes to communicate with a Modbus

Plus station (for example station 5) must use this address.

READ_VAR(ADR#{5.3}0.1.5, '%MW', 100, 10,%MW200:10, %MW300:4)

Quantum

Note: Routing between FIPWAY and Modbus Plus is carried out by the automatic system. In a network architecture, it is not necessary to declare a bridge station.

Communication from a Modbus

Plus network

If a Modbus Plus segment is integrated into an X-WAY architecture, a Quantum station cannot communicate with stations connected to another network in this architecture (for example FIPWAY or ETHERNET TCP/IP). Communication is only possible with the local Premium.

Premium

In a Modbus Plus architecture, a Quantum PLC application can communicate with a Premium PLC and vice versa.

Communication from a Premium PLC to a remote station is described in the exchange service on remote networks.

Communication from a Quantum PLC to a Premium PLC is available via MSTR blocks.

In this case, the Premium or Micro are servers; therefore, all Modbus Plus stations connected to a network architecture, up to a maximum of 5 levels, can communicate with them.

MSTR read

The Quantum station sends a read request to the Premium station using an address path: 8.5.1.0.0 (routing path).

The MSTR function block is used to read or write internal words of a Premium or

Micro station. The parameter of the slave register of the MSTR function block directly indicates the address of the internal word %MW of the PL7 application. This function block is also used to read or reset the statistics counters of a Premium or

Micro station. This request is executed directly by the PCMCIA card which responds directly.

Peer Cop service

Peer Cop Service

Introduction The Peer Cop service is an automatic exchange mechanism between stations connected to the same local Modbus Plus segment.

This service is used to maintain constant control over inputs / outputs which have been remoted by implicit exchanges.

The Premium PLCs support two types of Peer Cop transfer: z z specific inputs specific outputs

Specific Inputs and Outputs

Report

The specific inputs and outputs are point to point services which use the multicast protocol (multistations). Each message contains one or several destination addresses for sending the data. This function is used to exchange data to several stations without repetition.

Three types of report are associated with the specific inputs and outputs: z z z activity bit: provides information on the availability and validity of the status bits status bits (to the number of one bit per station): z ensure coherence between the number of specific inputs configured and the number of specific inputs received z indicate if the specific inputs have been received during the Timeout presence bits (to the number of one bit per station): indicate if the specific inputs have been refreshed

Note: the presence bits are only valid for the specific inputs.

Read and write service on local segment

Introduction A Micro or Premium PLC can exchange data with stations connected to the local

Modbus Plus network.

Data exchanges The functions READ_VAR and WRITE_VAR are used to access remote stations on the same local segment, bits, internal words or input and output words in read / write mode.

These exchanges are explicit exchanges managed by the application.

The addressing from a Premium station will be for example: z in read mode z

READ_VAR (ADR#0.1.10, '%MW', 10, 20, %MW10:20, %MW100:4) in write mode

WRITE_VAR (ADR#0.1.10, '%MW', 10, 20, %MW10:20, %MW100:4)

The following table describes the different parameters of the function:

Modbus Plus programming

Exchange service on remote Modbus Plus networks

Introduction

Access to a remote station.

A Micro or Premium PLC can exchange data with stations connected to other

Modbus Plus segments via BP85 Bridge Plus bridges.

To access a station connected to another network segment, it is necessary to indicate the full address path (routing path) in the information sent.

Beforehand, indicate, in the request, the address of the first destination connection point on the local bus.

Next, clarify, in the data to be sent, each address of the devices which will allow the passage of the exchanges to the destination station.

Data exchanges This type of exchange is accessible via the function SEND_REQ . To differentiate the reading and writing of data from a remote station, a request code is associated to the function SEND_REQ . These exchanges are explicit exchanges managed by the application.

The addressing from a Premium station will be for example: z in read mode

SEND_REQ (ADR#0.1.61, 16#36, %MW300:50, %MW450:150, z

%MW600:4) in write mode

SEND_REQ (ADR#0.1.61, 16#37, %MW300:50, %MW450:150,

Global data exchange service

Introduction The global data exchange service is a simple exchange mechanism which is used to send broadcast messages between stations connected on the same Modbus Plus network.

During an exchange, a station which has the token can broadcast words destined for other stations connected on the network. A receiving station takes the content of words transmitted by the sending station, stores them in its PCMCIA card and sends them back to the network. The same applies to each station when the token is passed.

Precautions for use

For Premium and Micro PLCs, this service is provided by particular communication functions ( WRITE_GDATA and READ_GDATA ) periodically taken on by the application. It is not integrated in the Peer Cop transactions.

A Premium or Micro PLC can broadcast a maximum of 32 words.

Writing global data

Note: Data transfer from one station to another is automatic.

To read the global data which is sent, the application of the receiving station must read its PCMCIA card.

This type of exchange is accessible via the function WRITE_GDATA .

The addressing from a Premium station will be for example:

WRITE_GDATA (ADR#0.1.SYS, %MW100:x, %MW200:4)

The following table describes the different parameters of the function:

Parameters

Reading global data

This type of exchange is accessible via the function READ_GDATA .

The addressing from a Premium station will be for example:

READ_GDATA (ADR#0.1.10, %MW30:32, %MW300:4)

The following table describes the different parameters of the function:

Parameters

Introduction

Associated manuals

Communication via FIPIO is part of Schneider Automation’s global WORLDFIP package.

FIPIO is a field bus used to delocalize the inputs/outputs of a PLC station and its industrial periphery to be as close as possible to the working part.

The FIPIO protocol uses producer/consumer exchanges (e.g.: common words) and the bus is managed via a bus arbiter.

If you require further information you should consult the following manuals:

Hardware compatibility relating to the bus manager

General

Availability

Capacity

The binary flow of the bus is 1 Mbits/s and it can extend to a length of up to 15 Km, with four optical or electric repeaters (TSX FP ACC 6).

The FIPIO bus links up to Hirshmann optical transmitters, which allows medium redundancy architectures to be created.

This type of communication is available via built-in links on Premium PLCs from version V3.0 onwards.

The PLCs with built-in FIPIO links are the following: z z

TSX type processors: z TSX P57 153, z z

TSX P57 253, TSX P57 2823,

TSX P57 353/353A z TSX P57 453/453A, TSX P57 4823/4823A.

PCX type processors: z PCX57353.

The bus manager can also be a PLC of the following type: z z

TSX 47-107 version 5.3 minimum,

S1000.

Processors with built-in FIPIO links are used to manage 128 connection points

(TSX P57 153 = 64) on the bus (addresses 0 to 127).

The bus manager is connected to address 0, and address 63 is reserved for the programming and diagnostics terminal.

These processors have a RAM memory for saving the configurations of devices connected to the bus. This memory has a maximum capacity of 94,320 bytes and

213,104 for (TSX P57 453/453A/4823/4823A) processors.

General

Software compatibility relating to the bus manager

Explicit exchange limits

Reminders

X-TEL software

Processors with a built-in FIPIO link can simultaneously activate 24 explicit exchange functions.

An exchange request addressed to a FIPIO device can take several MAST task cycles. Thus, it is absolutely necessary to manage the exchange management parameter words for all exchanges of explicit variables including

READ_STS %CH@channel and READ_STS %CH@MOD .

For example, if 24 functions are being processed simultaneously or if 25 functions are triggered in the same task cycle, the 25th, or any new function, will not be served and will terminate in error.

For a READ_STS exchange, if the twenty-fifth exchange is impossible, the report signals a communication fault in the word: %MW\p.2.c\m.v.2.

For WRITE_CMD , READ_PARAM , WRITE_PARAM , RESTORE_PARAM exchanges, the report signals a communication fault in the word %MW\p.2.c\m.v.1. A likely cause is a lack of system resources to provide the service.

The system word %SW155 contains the number of explicit exchanges in progress.

Bit %SW116: x2 switches to 1 if the maximum number of simultaneous explicit exchanges is reached or exceeded.

When the bus manager is a series 7 PLC (TSX 47-107), the configuration of the bus and the manager is performed by the X-TEL software workbench, of version 6.0 or later.

General

Software compatibility: Network transparency

Introduction

Transparency restrictions

Exchanges from a remote station to the FIPIO bus or vice versa are possible under certain conditions.

Inter-station communication with FIPIO is only available if the bus arbiter is a

Premium PLC, of at least version V3.3.

Exchanges from a third-party device to a PLC connected as a FIPIO slave are only possible if the PLC is a Premium of V3.3 at least. Communication with a Micro PLC is not possible.

A FIPIO agent does not communicate with the exterior.

Only one programming terminal can be connected to the FIPIO bus. If it is present in the configuration, it must be connected to the default connection port (63).

This programming terminal cannot be used to load the application onto the FIPIO bus arbiter.

Software compatibility: communication with the exterior

Introduction To communicate from a station connected to the FIPIO bus to an outside device, the transmitter station must address the master PLC and not the destination device

(requests are not routed directly).

Example

Note: the master PLC application transfers these requests to the destination device.

In the following example, an exchange from the FIPIO bus to the Uni-telway bus has to be performed. For a transfer in the opposite direction, the procedure is identical.

Premium master, Serie 7

Step 2

Step 1

Uni-telway

Ad0 = 1

Ad1 = 2

Ad2 = 3

Step 1 The transmitter station, connected to connection port 6 on FIPIO, sends the request to the master PLC. The destination address is the master PLC address.

WRITE_VAR (ADR#\6.1.0\SYS, %MW,0,10, %MW:10, %MW100:4)

The master PLC generates the report.

246

35013154.02 07/2208

Step 2

General

When the master PLC application receives the request from the transmitter station, it directs it to the destination device in accordance with the Uni-telway protocol.

WRITE_VAR (ADR#0.0.1, '%MW', 100, 10, %MW10:10, %MW40:4)

The report is sent to the master PLC.

Compatibility information relating to TBX devices

Introduction

Rules of use

Addressing

The following compatibility information relates to: z z the addressing supported by the different connectable devices, the memory space that the devices take up in the configuration RAM.

If a device linked to a connection port is modular, it must be homogeneous at an application-specific level. Discrete base and extension or analog base and extension (not a mixture of discrete and analog).

The device is only controlled by one PL7 task (FAST or MAST) (no assigning of channel groups of the same TBX to different tasks).

The FIPIO addressing depends on the type of device:

FIPIO bus operating mode

Introduction The FIPIO bus operating mode is linked to the processor operating mode and to the physical state of the bus.

If the number of physical errors detected by the processor is endangering the nominal operation of the devices connected to the bus, the processor stops all bus activity. In this case, the devices connected apply the fallback values to the inputs/ outputs.

Operating mode The operating mode is as follows:

Phase

Description

Cold restart of the processor with a FIPIO application: the bus is started automatically; the I/Os are monitored and commanded.

Downloading an FIPIO application: the bus is started automatically; the inputs/ outputs are monitored and commanded.

If the processor detects serious physical errors, the FIPIO bus is stopped automatically. The connected devices apply the fallback values; the processor no longer monitors the inputs/outputs. A serious physical error is for example the disconnection of the line plug, the disconnection of the FIPIO terminal block on the processor, etc…

Following an automatic stop (serious errors detected by the processor): z the bit %SW144:x2 is set; the processor periodically carries out a restart attempt, trying to monitor and command the inputs/outputs of the connected devices. This is automatic mode.

z the bit %SW144:x2 is cleared; to restart the bus, there a user action must be performed via the program or via the programming terminal. Set bits

%SW144:x0 and %SW144:x1 to 1. This is manual mode.

Warm restart: the bus is restarted automatically if it has not been stopped voluntarily by an action on the system word %SW144 bits 0 and 1. The bus is returned to the state it was in before the power outage.

If %S0 = 1 the system words are initialized, and if the bus had been stopped, it is restarted.

General

Information on manual mode

Information on automatic mode

If the FIPIO bus is stopped without a voluntary action on the system word %SW144, this means that the processor has detected physical errors which prevent the nominal operation of the bus and the connected devices.

In this case, and only in this case, , if bit %SW144:x2 is set to 1 (automatic start), the processor will make periodic and automatic attempts to restart the exchanges on the bus.

If bit %SW144:x2 is at 0 following the stopping of the bus owing to physical errors, it is necessary to reset bits %SW144 x:0 and %SW144 x:1 via the program or via the programming terminal in order to restart the FIPIO bus. In this case, the bus will restart if, and only if, the physical error which caused the stop has disappeared .

Example

If %SW144:x0 is set to 0 (via the programming terminal or via the program) the production/consumer function (PC) stops. No more variables or messages are exchanged on the bus.

If %SW144:x1 is set to 0 (via the programming terminal or via the program) the bus arbiter function (BA) stops. There is no more scanning of variables or messages on the bus.

To completely and voluntarily stop the activity on the FIPIO bus, it is necessary to simultaneously set bits 0 and 1 of the system word %SW144 to 0 via the programming terminal or via the program.

if bit %SW144 x:2 = 1 on disconnection/reconnection of the processor FIPIO terminal block, the bus will be restarted automatically.

The devices will be monitored once again and will be able to apply the program values.

if bit %SW144 x:2 = 1 on disconnection/reconnection of the processor FIPIO bus, the connected devices on the bus will be neither monitored, nor will they be able to apply the program values.

The devices will be monitored once again if the user sets bits %SW144:x0 and

%SW144:x1 = 1.

Network cycle time: mono task application

Introduction

Calculation of the network cycle time

The network cycle time for a mono task application is calculated for the following configuration: z z the length of the bus is 1 Km, the values corresponding to the reversal and silence times and the bandwidths are default values (automatic mode).

For an application which has all the devices configured in the same task, the value of the network cycle time of the task, in milliseconds, is obtained, for information purposes only, by the following formula:

TCR_TASK= 1,45 +

Fipio Configuration

There are two types of exchange on a Fipio bus: z z

Exchanges of cyclic variables which are reserved for the process data,

Exchanges of aperiodic variables which concern the configuration of connected devices, the adjustment and the messaging.

A decrease or increase of the bandwidth of the aperiodic exchanges (Variables and

Messages) slows down or accelerates the output of the configuration or adjustment variables which can circulate on the bus. The same applies to a decrease or increase of the aperiodic bandwidth of the messaging facility.

The following table gives a description of the aperiodic bandwidths:

How to access PL7 task configuration in FIPIO mode.

Introduction

Procedure

FIPIO Bus and device configuration modifies the task network cycle times in accordance with the input/output updating of each PL7 task.

These modifications can result in constraints on: z z task type (cyclic or periodic), as well as its execution time and watchdog,

FIPIO input/output processing in relation to the task cycle (controlled or free).

The PL7 software is used then to manage the inputs/outputs according to the MAST or FAST tasks and their network cycle time.

The following table shows the procedure for accessing the MAST and FAST tasks in FIPIO mode:

In this mode, input/output refreshing is correlated with the task period. The system guarantees input/output updating during one period only. Only the inputs/outputs associated with this task are refreshed.

Choosing this mode imposes the following constraint:

The PLC task period (MAST or FAST) must be greater than or equal to the network cycle time

In this mode, no constraints are imposed on the task period. The PLC task period

(MAST or FAST) can be less than the network cycle time.

In this case, the task can be carried out without updating the inputs/outputs.

Selecting this mode provides the possibility of having the shortest possible task times for an application where the rate is critical.

Introduction

Confirmation refused

On completion of the FIPIO bus configuration, and in order to be recognized in the new application, the global bus configuration must be confirmed.

The PL7 then checks the constraints associated with this new application. If the imposed constraints are not respected, no scanning table is created.

A message window opens in this case.

Fipio Diagnostics

Diagnostics mode

Introduction In online mode it is possible to perform general diagnostics on the bus errors and device faults.

This diagnostic is possible by using screens available in the PL7 or the bits and system words managed by the application software.

Two modes are available: z z

FIPIO bus monitoring, device monitoring with or without a fault history.

Communication counters

Every configured connection point (including connection points 0 and 63) has a report variable. This variable contains the communication counter and performance values.

This variable has: z z z the activity counters numbered from 16#00 to 16#20 and standardized as

WORLDFIP, the error counters numbered from 16#21 to 16#7F and standardized as

WORLDFIP, the manufacturer counters numbered 16#80 to 16#FF these counters are not standardized as WORLDFIP.

The error counters change when there are communication errors on the FIPIO bus.

Diagnostics screens

Four screens display the status of the various counters and thus the communication errors: z z z z

The FIPIO bus monitoring screen provides a global view of the FIPIO bus, it displays the communication errors on the whole bus.

The Device monitoring screen provides a synthesis per connection point; it features all the connection points and indicates the status of the error counters per connection point.

The Device monitoring at connection point n screen shows all the counters and their status at a given connection point.

The Communication fault history screen is a fault history, which dates and retains the fault counter statuses to provide a trace.

Only one screen of each type can be open (one per connection point for the third type). If you try to open a screen which is already open, it will appear instantaneously.

Elements and functions

Each line has: z z z an icon representing the state of the error counter (the reference state being the state at screen opening): z white for normal state, z red for a faulty counter having changed since the reference state, the hexadecimal counter number, the counter labels (given by the WORLDFIP standard).

312

35013154.02 07/2208

Fipio Diagnostics

Diagnostics On screen opening or on reset request, the report variables from all the connection points are read by a cyclic communication (one per second).

The counter values from each report variable are stored to create a reference state.

The time between reading and rereading the same variable is equal to the number of configured devices + 2 (0 and 63) in seconds.

As soon as the error counter value becomes different from its reference value, the counter icon goes red, regardless of the connection point. Reading the counter labels provides the type of error detected.

Example

Counter 21 goes red. This means that at least one counter 21 from all the counter

21s has changed.

Bus monitoring via the application

In PL7, the %SW150 and %SW151 system words indicate the number of frames sent and received by the channel manager.

If one of these two counters stops, it indicates that the FIPIO channel manager function has stopped.

The user is made aware of this stop in the configuration screen in online mode, when the background of connection point 0 goes red.

How to disable device monitoring

On screen opening or on reset request, the report variables from all the connection points are read by a cyclic communication (one per second).

The counter values from each report variable are stored to create a reference state.

The time between reading and rereading the same variable is equal to the number of configured devices + 2 (0 and 63) in seconds.

A connection point is considered faulty if the value of one of the error counters has changed since the reference state. When the point is faulty, the icon turns red.

Diagnostics are only sent back if there is a communication between the bus manager and the faulty connection point. Errors correspond to the WORLDFIP standard defined error counters.

The following procedure describes how to disable the device monitoring on the bus.

Step

Action

Click on the checkbox belonging to the connection point to be disabled.

The following elements are associated with each counter: z z z z z z one icon indicating the state of the counter since the reference state: z z white: no change, green: change in the activity or manufacturer counters, z red: change in the error counters (the current value is different from the reference state).

the hexadecimal counter number, its hexadecimal reference value, its hexadecimal value during the last read, its current hexadecimal value, its label according to the WORLDFIP standard or the Counter not listed label for the manufacturer part.

Diagnostics On screen opening or on reset request, the report variables from all the connection points are read by a cyclic communication (one per second).

The counter values from each report variable are stored to create a reference state.

A connection point is considered faulty if the value of one of the error counters has changed since the reference state. When the point is faulty, the icon turns red.

Diagnostics are only sent back if there is a communication between the bus manager and the faulty connection point. Errors correspond to the WORLDFIP standard defined error counters.

Introduction A device conforming to the standard Fipio communication profiles can be linked to a Fipio bus, to exchange the input/output variables.

Data exchanges with devices are used to: z z z exchange inputs/outputs, write configuration or adjustment parameters, diagnose a connected device.

There are three types of standard profile: z z z

FRDP: Fipio Reduced Device Profile

FSDP: Fipio Simple Device Profile

FEDP: Fipio Extended Device Profile

Volume of data exchanged

The device profiles, which conform to a standard profile are a function of the number of inputs and outputs to be exchanged.

FIPIO Agent: General

Introduction The Micro or Premium PLCs, equipped with the PCMCIA TSX FPP 10 card on their built-in communication channel, are agents on the FIPIO bus.

The FIPIO function agent is used to perform two types of data exchange: z z periodic exchanges of information with the manager (shared variables type), aperiodic exchanges of messages with the manager, from CCX 17 devices or with other agents.

Note: this function is available with the TSX FPP 10 card, minimum version V1.8.

35013154.02 07/2208

359

Fipio Agent

Periodic data exchange

Introduction Each FIPIO Agent PLC uses 64 consecutive %MW words to exchange the periodic data. z z

The 32 first words are reserved for transmitting the information to the manager.

The 32 remaining words are reserved for receiving the information.

Note: the status %MW words and the command %MW are not significant.

Fipio Agent

Special cases

Introduction A Premium PLC which is registered as an FIPIO Agent can communicate with a

TSX 47-107 or APRIL 5000 manager.

For these uses, an FIPIO Agent is registered on the bus by registering a standard profile to the connection point.

The registered standard profile is as follows: z z z

Device family: STD_P

Standard: FED M32

Communicator: TSX FPP 10
