Loss of communication on the Modbus network

NOTE: During startup, because the default fallback mode is "forced stop", if no communication has previously been established, the red "ERR" LED will flash after one minute (default timeout value).

Addressing Using Switches

The Modbus communication module address is defined by switches located on the underside of the module. Simply turn the module over to access them:

The range of accepted values is between 1 and 31.

The address coding is in binary format.

The least significant bit is on the right, indicated by .

Address 0 is not taken into account by the module, since it is used by the Master for a broadcast request.

Caution: Address selection differs from that on the LULC031 Modbus communication module.

NOTE: Addressing is only taken into account when the communication module is powered up.

1743234 03/2009

Order of Mounting on a Base

The LULC032 module is installed in a controller base, the LULC033 module is installed in a power base or a controller base (on the underside of the control unit which locks it in position).

To install the module in the power base or controller base:

Step Action

1 Choose the prewired coil connection terminals.

2 Insert the LULC032-033 Modbus communication module.

3 Insert the control unit which locks the module.

The diagram below illustrates these steps. Installation of the LULC032-033 Modbus communication module corresponds to step (2). The numbers indicate both the order of mounting for the components and their location.

Power-up with an LUCM Multifunction Control Unit

LUCM and Power Base

The power-supply source must be the same for the LULC032-033 Modbus communication module and the LUCM multifunction control unit.

It is essential that the LUCM multifunction control unit and the LULC032-033 Modbus communication module are powered up simultaneously. Indeed, monitoring of the internal dialog between the LUCM and the LULC032-033 will produce two error messages depending on the order in which these objects were powered up.

When the A1-A2 terminals are not yet powered up (24V ), there are 3 possible scenarios for powering up the 24V Aux:

Comment

The "M15" fault is displayed. This only occurs when the LULC032-033 Modbus communication module has already been used with the LUCM multifunction control unit.

The LUCM control unit is identified by the LULC032-033 Modbus communication module when the 24 V Aux for the LULC032-033 Modbus communication module is switched on. If the 24 V Aux for the LUCM control unit is switched on for longer than twice the duration of the timeout (i.e., more than 1 s), the "M101" fault is displayed (register 451, communication module internal faults).

NOTE: Both these faults are reset by powering down and then powering up the LULC032-033 Modbus communication module (power cycle) and the LUCM control unit.

LUCM and Controller Base

The 24 V module power supply is provided by the LUTM controller.

Connection to the RS485 Bus

General

There are several ways in which the user can connect the communication module to the RS 485 bus:

 Direct connection to the bus via a VW3A8306TF•• T-junction box  Connection to the bus via a splitter box  Connection to the bus via SCA type junction boxes

For Interference Protection:

Use the Schneider Electric cable with 2 pairs of shielded twisted conductors (references: TSXCSA100, TSXCSA200, TSXCSA500, VW3A8306TF••).

Keep the Modbus cable away from the power cables (at least 30 cm).

Create crossovers of the Modbus cable and the power cables at right-angles, if necessary.

NOTE: For more information, consult guide TSX DG KBL F: "Electromagnetic Compatibility of Industrial Networks and Fieldbuses".

The RS 485 standard allows variants of some characteristics:

 Polarization  Line terminator  Number of slaves  Length of bus

The new Modbus specification, published in 2002 on the Modbus.org site, defines all these characteristics precisely. All new Schneider Electric devices conform to this specification.

Installing the LULC032-033 Modbus Module

Connection to the Bus via a Tee

The standard diagram corresponds to the Modbus specification published in 2002 on the Modbus.org site (Modbus_over_serial_line_V1.pdf, Nov 2002) and in particular to the 2-wire multidrop serial bus diagram.

The LULC032-033 Modbus communication module conforms to this specification.

The simplified diagram is as follows:

Master

Slave 1 Slave 2

1743234 03/2009 23

Installing the LULC032-033 Modbus Module

The characteristics for direct connection to the bus are as follows:

Designation Description

Type of trunk cable Single shielded twisted pair cable and at least a 3rd conductor

Maximum length of bus 1000 m at 19,200 bps with the Schneider Electric TSX CSA•• cable

Maximum number of stations (without repeater)

Maximum length of tap-offs

Bus polarization

Line terminator A 150 ohm resistor +/- 5%

Common polarity Yes (Common), connected to the protective ground in at least one point on the bus

Connection to the Bus via a Splitter Box

The connection diagram for connection to the bus via a splitter box is as follows:

32 stations, i.e., 31 slaves

 20 m for one tap-off  40 m divided by the number of tap-offs on the multiple junction box

 A 450 to 650 ohm pulldown resistor at the 5 V  A 450 to 650 ohm pulldown resistor at the Common

This polarization is recommended for the master. There is no polarization at the RS 485 terminal on the communication module.

NOTE: It is advisable to place a line terminator at each end of the bus to avoid malfunctions on the

communication bus. This means that a tee should not have a free connector. It is either connected to a slave or to the master, or there is a line terminator.

NOTE: It is important to connect the bus to the "IN" input (or the screw terminals on the bottom) of the splitter box. Connection to another splitter box is made via the "OUT" output.

Starting up the Module via the Registers

General Information on Start-up via the Registers

All the LULC032-033 communication module settings are implemented - or simply displayed - via the Modbus registers.

Access to Parameters

The module I/O parameters are set by one of the following three methods:

 The Modbus RJ45 port, via the application PLC  The LUCM multifunction control unit’s terminal port  Locally, via the LUCM multifunction control unit’s keypad

1743234 03/2009

Data-Exchange Format

Modbus Format

Communication is based on the slave Modbus RTU protocol.

The data format is as follows:

1 start bit 8 data bits 1 parity bit 1 stop bit

NOTE: The detailed format of these requests is explained on the www.Modbus.org site.

Initialization

Initialization consists of two phases:

Starting up the Module via the Registers

When the auxiliary 24 V is powered up, the LULC032-033 Modbus communication module is initialized:

 The addressing is taken into account.  The type of control unit is taken into account.

At the end of the initialization phase, the LULC032-033 Modbus communication module automatically identifies the configuration parameters (speed and parity) of the RS 485 link as soon as traffic is detected on the network. After analysis of up to 20 frames at a speed of 19,200 baud, initialization continues (at 1200 baud, the number of frames is higher):

 The default or configured speed is taken into account.  The Master parity is taken into account.

Read-Write Zones

Exception Code

The memory zone from 0 to 19,999 can be accessed by the client.

- Reading the zone of a 'Reserved' register (or non-set) causes a correct response (value 0).

- Writing to the zone of a 'Reserved' register causes a correct response (value 0). The write operation is not taken into account and the contents remain equal to 0.

- Writing to the zone of a 'Read only' register causes a response with an exception code (code 03).

The memory zone 2000 is private and therefore reading/writing is not authorized. All accesses will be signaled by an exception code (code 02).

The presence of an exception code is indicated by the report from the PLC (refer to the Modbus master module documentation).

The Modbus exception codes supported are as follows:

Value of the exception code Name Comment

Hexadecimal Decimal

0x01 1 Illegal function Unknown request code

 Register address invalid  Access to the private memory

0x02 2 Illegal data address

0x03 3 Illegal data value

zone (address  20000)

 Writing to a "read-only" register

The memory zone is prohibited in both read and write modes

 Invalid value

The write command is interrupted

1743234 03/2009 43

Starting up the Module via the Registers

Speed and Parity

The recognized values are as follows:

Possible values Factory value

Speed 1200, 2400, 4800, 9600 and 19,200 baud. 19,200 baud

Parity Even, odd, no parity (parity bit deleted). Even*

* All versions (except LULC032 < V1.3: factory-configured with "No parity").

TSX Micro or Premium Platform

Applications for Micro and Premium PLCs are designed and implemented using PL7 software.

READ_VAR or WRITE_VAR requests (see Modbus Requests and Programming Examples) are used to read or write respectively the value of one or more consecutive objects of the same type (bit, word), in PL7 language.

NOTE: For more details concerning Modbus communication programming within a TSX platform, refer to the PL7 online help, Communication Volume 2/Modbus communication.

1743234 03/2009

Factory Configuration

The communication module parameters are set in order to determine:

 The operating mode  The reset mode for thermal overload faults  The correspondence between the communication module outputs and the LUTM controller inputs

The parameter registers (Modbus protocol) are accessible in read/write mode. The factory-set values are as follows:

Starting up the Module via the Registers

Customizing Your Configuration

You can use the factory settings (see Factory Configuration) or customize your configuration.

The following parameters can be set:

 Control unit configuration  Control unit ID  Timeout duration  Fallback mode  Control mode with a LUTM controller.  Inversion of the output states  Assignment of outputs LO1, OA1, OA3, 13 and 23  Recovery after stopping  Control unit forcing

UNEXPECTED OPERATION

A configuration can be loaded or edited via both Modbus ports (via the communication module or via the control unit LUCM). One configuration can then overwrite another, as the system does not prevent such an action. The result is not certain.

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

WARNING

Control unit configuration (Reg 602)

Register 602 (accessible in read/write mode) is used to configure the control unit (reset mode 602.0-2, and communication 602.4).

Reg• Value Comment

602.0 1 Resetting is manual (by default). Bits 1 and 2 are at 0.

0 You have activated either bit 1 (remote reset) or bit 2

602.4 1 Communication with the LUCM/MT multifunction control

0 When forced to 0, this bit inhibits communication

Control unit configuration (Reg 680)

The control unit is identified each time the communication module is powered up.

However, the multifunction control unit memorizes the reference of the communication module assembled with it.

To use a multifunction control unit on its own, once it has been used with a communication module, identification register 680 is reinitialized locally via the keypad in the menu (Id = 0) or via the remote LUCM Modbus terminal port (value 0 written to register 680).

Timeout Duration (Reg 681)

Register 681 (accessible in read/write mode) is used to set or read the value of the timeout on loss of communication with the PLC. Following loss of communication, the timeout corresponds to the time before switching to fallback mode. Loss of communication results in a warning, which is signaled by register 460 = 109.

AUTOMATIC RESTART OF THE MOTOR

When communication stops,outputs OA1-OA3 take the status corresponding to the selected fallback mode (register 682), but command bits 704.0 and 704.1 are not modified.

During the loss of communication warning (register 703 or push button on the controller), the motor will restart automatically if command bits 704.0 or 704.1 have not been reset to zero first by the PLC application.

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

683.

Value Operation Comment

'Mixed' mode (input I.10 has priority)

Outputs 13 and 23 are only controlled by the bus.

The state of inputs I.1 and I.2 does not affect outputs 13 and 23.

Outputs 13 and 23 are only controlled by inputs I.1 and I.2.

Commands via the bus are not taken into account.

'Local' mode if I.10 = 1

'Remote via the bus' mode if I.10 = 0

NOTE: Commands transmitted during communication are passed directly to the output relays, without wiring between the communication module outputs and inputs I.1 and I.2.

Inversion of output states (Reg 684)

Depending on requirements (signaling, run, stop, etc.), it is possible to assign NO or NC behavior to outputs OA1, OA3 and LO1, by configuring register 684.

To do this, define the output concerned ==> register 684.

Starting up the Module via the Registers

Outputs 13 and 23 are only controlled by inputs I.1 and I.2.

Commands via the bus are not taken into account.

Outputs 13 and 23 are only controlled via the bus, from the PLC.

Modifying Output Assignments

The tables below show how the assignments of outputs LO1, OA1, OA3, 13, and 23 can be modified. To modify the assignments (factory values), write a different value (0 to 45), referring to the 'TeSys U Communication Variables' User’s Manual.

UNEXPECTED OPERATION

Before modifying an output's assignment by means of parameterization, you must note the following information. Otherwise, you run the risk of unexpected operation.

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

Register 704 is used for controlling the motor-starter. The following are associated with this register: functions for monitoring loss of communication, fallback mode (register 682), reflex functions or recovery mode after stopping (register 688). Only the outputs activated by bits 704.0 and 704.1 benefit from these functions.

In addition, command bits 704.0 and 704.1 are independent and can be activated simultaneously.

Using register 700 to activate outputs is comparable with unconditional forcing.

Setting the parameters of output LO1 (Reg 685 LSB)

If you use register 704 to control outputs OA1-OA3, writing the value 1 to register 688 allows you to lock the motor and prevent it restarting following the occurrence of certain events:

 Loss followed by restoration of 24V DC (outputs OA1-OA3)  Change in position of rotary knob on power base followed by return to Ready position.

When one of these events occurs, command bits 704.0 and 704.1 (outputs OA1-OA3) are forced to 0 automatically. As long as one of these events remains pending, if values are written to register 704, the module will return exception code 02. Once these conditions have disappeared, control of the motor can be restored by sending a new run command.

AUTOMATIC RESTART OF THE MOTOR

In the case of cyclic writing to register 704 (e.g., an LUFP• gateway in its predefined configuration), this monitoring function must be used with caution. The application program must take this state into account and request that bits 704.0 or 704.1 are written to 0. Otherwise, when this event disappears, the motor will restart automatically.

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

Modbus Requests and Programming Examples

Modbus Requests

The recognized Modbus requests are as follows:

Code value

Hexadecimal Decimal

0x03 3 Read multiple registers Read mode

0x06 6 Write single register

0x10 16 Write multiple registers

0x2B 43 Read register identification

Name Comment

Write mode

Read mode for identifying the LULC032-033 Modbus communication module

The maximum number of registers per request is limited to 100.

NOTE: The "Broadcast" function is supported. To use it, a write operation (code 6 or 16) to address 00 is necessary.

WARNING

UNEXPECTED OPERATION

Use of this device on a Modbus network that uses the broadcast function should be considered with caution.

This device has a large number of registers that must not be modified during normal operation.

Unintended writing of these registers by the broadcast function may cause unexpected and unwanted product operation.

For more information, refer to the "Internal Communication Variables" User’s Manual.

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

Example of a Read Operation

The example below describes a READ_VAR request, within a TSX Micro or Premium platform, in order to read the motor-starter states at address 4 (slave no. 4) contained in internal word MW0:

1 Address of the module with which you wish to communicate: 3 (module address), 0 (channel), 4 (module address

on the bus)

2 Type of PL7 objects to be read: MW (internal word) 3 Address of the first register to be read: 455 4 Number of consecutive registers to be read: 1 5 Word table containing the value of the objects read: MW0:1 6 Read report: MW100:4

Example of a Write Operation

The example below describes a WRITE_VAR request, within a TSX Micro or Premium platform, in order to control a motor-starter by sending the content of internal word MW 502:

1 Address of the module with which you wish to communicate: 3 (module address), 0 (channel), 4 (module address

on the bus)

2 Type of PL7 objects to be written: MW (internal word) 3 Address of the first register to be written: 704 4 Number of consecutive registers to be written: 1 5 Word table containing the value of the objects to be sent: MW502:1 6 Write report: MW200:4

Use of the Main Registers for Simplified Management

Before implementing a motor-starter, it is useful to know which of the main registers are invoked, and in what order.

Diagram of Register Usage

The diagram below provides basic implementation information, using the following registers: configuration, control and monitoring (system state, measurements, faults and warnings, acknowledgment). Starting with the factory configuration (predefined), you will easily be able to follow or anticipate how your system behaves.

Fault and Warning Management

Displaying Faults

The presence of a fault is signaled by various indicators:

 State of the LEDs on the LULC032-033 Modbus communication module

With a power base:

 State of the power base rotary knob (0 or "trip")  State of the output relays

With a controller base:

 State of the LEDs on the controller base  State of the output relays

With a standard or advanced control unit:

 Internal signals sent to the LULC032-033 Modbus communication module

With a multifunction control unit:

 Warning  Message(s) displayed on-screen  Internal dialog with the LULC032-033 Modbus communication module

 Presence of an exception code (report from the PLC). See Exception Code, page 43.

NOTE: The warning and the fault are taken into account in the relevant registers. For more information, refer to the "TeSys U Communication Variables" User’s Manual: fault monitoring registers (450 to 452) and warning monitoring registers (460 to 461).

Description of Reflex Stop Functions

The reflex stop ensures accurate repeated position control, unhindered by the bus and PLC scan times.

There are two types of reflex stop function:

 Reflex1: "Reflex stop 1" function  Reflex2: "Reflex stop 2" function

Description of Reflex1

Sensor no. 1 (logic input LI1) directly controls motor stopping.

After a new run command (stop command then run command), the motor restarts even if something is still detected (LI1=1).

1 Bus 2 Sensor no. 1 (LI1)

NOTE: In the case of a reversing starter, the reflex stop works in both directions.

Data sequence

1743234 03/2009

Description of Reflex2

Sensor no. 1 (logic input LI1) controls motor stopping in forward mode.

Sensor no. 2 (logic input LI2) controls motor stopping in reverse mode.

After a new run command (stop command then run command), the motor restarts even if something is still detected (LI1 or LI2 = 1).

NOTE: Sensor no. 2 (LI2) does not affect forward mode and sensor no. 1 (LI1) does not affect reverse mode.
