Using the Modbus Communication Network

Overview

This chapter describes how to use the LTMR controller via the network port using the Modbus protocol.

WARNING
LOSS OF CONTROL The designer of any control scheme must consider the potential failure modes of control paths and, for critical functions, provide a means to achieve an acceptable state during and after a path interruption. Examples of critical control functions are emergency stop and overtravel stop. Separate or redundant control paths must be provided for critical control functions. System control paths may include communication links. Consideration must be given to the implications of anticipated transmission delays or interruptions of the link.⁽¹⁾ Each implementation of an LTMR controller must be individually and thoroughly tested for proper operation before being placed into service. Failure to follow these instructions can result in death, serious injury, or equipment damage.

LOSS OF CONTROL

The designer of any control scheme must consider the potential failure modes of control paths and, for critical functions, provide a means to achieve an acceptable state during and after a path interruption. Examples of critical control functions are emergency stop and overtravel stop.
Separate or redundant control paths must be provided for critical control functions.
System control paths may include communication links. Consideration must be given to the implications of anticipated transmission delays or interruptions of the link.⁽¹⁾
Each implementation of an LTMR controller must be individually and thoroughly tested for proper operation before being placed into service.

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

(1) For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control".

WARNING
UNEXPECTED RESTART OF THE MOTOR Check that the PLC application software: Considers the change from local to remote control, Manages appropriately the motor control commands during those changes. When switching to the Network control channels, depending on the communication protocol configuration, the LTMR controller can take into account the latest known state of the motor control commands issued from the PLC and restart automatically the motor. Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

UNEXPECTED RESTART OF THE MOTOR

Check that the PLC application software:

Considers the change from local to remote control,
Manages appropriately the motor control commands during those changes.

When switching to the Network control channels, depending on the communication protocol configuration, the LTMR controller can take into account the latest known state of the motor control commands issued from the PLC and restart automatically the motor.

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

Modbus Protocol Principle

Overview

The Modbus protocol is a primary secondary protocol:

Only one device can transmit on the line at any time.

The primary device manages and initiates the exchange. It interrogates each of the secondary devices in succession. No secondary device can send a message unless it is invited to do so.

The primary device repeats the question when there is an incorrect exchange, and declares the interrogated secondary device absent if no response is received within a given time period.

If a secondary device does not understand a message, it sends an exception response to the primary device. The primary device may or may not retransmit the request.

Modbus Dialog

Two types of dialog are possible between primary and secondary devices:

The primary device sends a request to a secondary device and waits for its response.
The primary device broadcasts a request to all secondary devices without waiting for a response.

Direct secondary-to-secondary communication is not possible. For secondary-to-secondary communication, the primary device must interrogate a secondary device and send back data received to the other secondary device.

Transparent Ready

The controller LTMR Modbus is of class A05 (Transparent Ready).

Configuration of the LTMR Modbus Network Port

Communication Parameters

Before any communication can start, use the TeSys T DTM or the HMI to configure the Modbus port communication parameters:

Network port address setting
Network port baud rate setting
Network port parity setting
Network port comm loss timeout
Network port endian setting

Network Port Address Setting

The device address can be set between 1 and 247.

Factory setting is 1, which corresponds to an undefined value.

Network Port Baud Rate Setting

Possible transmission rates are:

1200 Baud
2400 Baud
4800 Baud
9600 Baud
19,200 Baud
Autodetection

Factory settings is Autodetection. In Autodetection, the controller is able to adapt its baud rate to that of the primary device. 19,200 Baud is the first baud rate to be tested.

Network Port Parity Setting

The parity can be selected from:

Even
Odd
None

When Network port baud rate setting is in Autodetection, the controller is able to adapt its parity and stop bit to that of the primary device. Even parity is the first parity to be tested.

In Autodetection, the parity is set automatically; any previous setting is ignored.

Parity and stop bit behavior is linked:

If the Parity Is...	Then the Number of Stop Bits Is...
even or odd	1
none	2

Network Port Comm Loss Timeout

Network port comm loss timeout is used to determine the timeout value after a loss of communication with the PLC.

Range: 1-9,999

Network Port Fallback Setting

Network port fallback setting is used to adjust the fallback mode in case of a loss of communication with the PLC.

Network Port Endian Setting

The Network port endian setting allows to swap the two words in a double word.

0 = least significant word first (little endian)
1 = most significant word first (big endian, factory setting)

Modbus Communication Checking

Introduction

Configure the networking function last. Even when the connectors are plugged in, communication between the controller(s) and the PLC cannot start until you enter the correct communication parameters via SoMove with the TeSys T DTM or the HMI.

You can then check whether your system can communicate properly.

The Modbus communication checking sequence is:

Step 1

On the LTMR front face, check the following two LEDs:

Fallback
PLC Comm

The figure shows the LTMR front face with both Modbus communication LEDs:

The communication Fallback is indicated by a red LED (1).

If the red Fallback LED is...	Then...
OFF	the LTMR is not in communication fallback mode
ON	the LTMR is in communication fallback mode

The Modbus communication status, marked as PLC Comm, is indicated by a yellow LED (2).

If the yellow PLC Comm LED is...	Then...
OFF	the LTMR is not communicating
Blinking	the LTMR is exchanging frames (receiving or sending)

Step 2

If the product should be communicating but the LEDs are not lit, check the cables and connectors and correct any connection problems.

Step 3

If the product is still not communicating, check the configuration via:

SoMove with the TeSys T DTM, or
The HMI.

The detected communication interruption can be the result of a wrong address, speed or parity; or an incorrect PLC configuration.

Simplified Control and Monitoring

Overview

This is a simplified example of the main registers which control and monitor a Motor Management Controller.

Modbus Registers for Simplified Operation

The following illustration provides basic setup information, using the following registers: configuration, control and monitoring (system status, measurements, trips and alarms, acknowledgement).

Modbus Request and Programming Examples

Modbus Request

The following table indicates which Modbus functions are managed by the LTMR controller, and specifies their limits:

Code value		Function Name	Broadcasting	Modbus Standard Name
Hexadecimal	Decimal	Function Name	Broadcasting	Modbus Standard Name
0x03	3	Read N output words (multiple registers)	No	Read Holding Register
0x06	6	Write 1 output word (single register)	Yes	Preset Single Register
0x10	16	Write N output words (multiple registers)	Yes	Preset Multiple Registers
0x2B	43	Read identification (identification register)	No	Read Device Identification

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

WARNING
UNINTENDED EQUIPMENT 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 Communication variables list. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Example of a Read Operation (Modbus Request Code 3)

The following example describes a READ_VAR request, within a TSX Micro or Premium platform, in order to read the LTMR states at address 4 (secondary device n° 4) contained in internal word MW0:

1 Address of the device with which you wish to communicate: 3 (device address), 0 (channel), 4 (device 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 (Modbus Request Code 16)

The following example describes a WRITE_VAR request, within a TSX Micro or Premium platform, in order to control an LTMR by sending the contents of internal word MW 502:

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

Modbus Exception Management

Overview

The LTMR controller generally follows the Modbus requirements for the Exception Management.

Three special cases apply to the LTMR controller:

Bit-Field Registers
Exception Code 02 - Illegal Data Address
Exception Code 03 - Illegal Data Value

Bit-Field Registers

Some registers in the Register Map are bit-field. Based on the LTMR controller state, some bits in those registers shall not be writable. In this case, the LTMR controller shall reject the write to those bits meaning that no exception shall be returned. For example, bits that can be written only in configuration mode will be ignored (no exception returned) if the LTMR controller is out of the Sys Config State. The write to the bits not constrained by the LTMR controller state shall however occur.

Exception Code 02 - Illegal Data Address

In general, the LTMR controller shall return an illegal data address exception code, if the address is out of range or inaccessible. Specifically, the LTMR controller shall return an illegal data address if:

A Write request is sent to a Read only register.
The permission to write a register is not granted because of the LTMR controller state: this is the case, for example, when a register that can be written only in configuration mode is written while the LTMR controller is out of Sys Config state.

Exception Code 03 - Illegal Data Value

In general, the LTMR controller shall return an illegal data value exception code if there is a problem with the structure of the message, such as an invalid length. The LTMR controller shall also use this exception code if:

The data to be written is out of range (for standard and bit-field registers): this is the case if a write request of 100 is sent to a R/W register with a range of 0 to 50.
A reserved bit or register is written to a value different than 0.
Motor low speed command (bit 704.6) is set while the motor controller mode selected is not a two-speed mode of operation.

User Map Variables (User Defined Indirect Registers)

Overview

User Map variables are designed to optimize the access to several non-contiguous registers in one single request.

You can define several read and write areas.

The user map can be defined via:

A PC running SoMove with TeSys T DTM
A PLC via the network port

User Map Variables

User Map variables are divided into two groups:

User Map Addresses	800 to 898
User Map Values	900 to 998

The User Map Address group is used to select a list of addresses to read or write. It can be considered as a configuration area.

The User Map Value group is used to read or write values associated to addresses configured in the User Map Address area:

Read or write of register 900 allows to read or write the register address defined in register 800
Read or write of register 901 allows to read or write the register address defined in register 801,...

Example of Use

The following table gives an example of user map address configuration to access non-contiguous registers:

User Map Address Register	Value Configured	Register
800	452	Trip register 1
801	453	Trip register 2
802	461	Alarm register 1
803	462	Alarm register 2
804	450	Minimum wait time
805	500	Average current (0.01 A) MSW
806	501	Average current (0.01 A) LSW

850	651	HMI display items register 1
851	654	HMI display items register 2
852	705	Control register 2

With this configuration, monitoring information is accessible with one single read request through register addresses 900 to 906.

Configuration and command can be written with one single write using registers 950 to 952.

Register Map (Organization of Communication Variables)

Introduction

Communication variables are listed in tables, according to the group (such as identification, statistics, or monitoring) to which they belong. They are associated with an LTMR controller, which may or may not have an LTME expansion module attached.

Communication Variable Groups

Communication variables are grouped according to the following criteria:

Variable Groups	Registers
Identification variables	00 to 99
Statistics variables	100 to 449
Monitoring variables	450 to 539
Configuration variables	540 to 699
Command variables	700 to 799
User Map variables	800 to 999
Custom Logic variables	1200 to 1399

Table Structure

Communication variables are listed in 4-column tables:

Column 1

Column 2

Variable type

Column 3

Variable name and access via Read-only or Read/Write Modbus requests

Column 4

Note: code for additional information

Note

The Note column gives a code for additional information.

Variables without a code are available for all hardware configurations, and without functional restrictions.

The code can be:

numerical (1 to 9), for specific hardware combinations
alphabetical (A to Z), for specific system behaviors.

If the Note Is...	Then the Variable Is...
1	Available for the LTMR + LTMEV40 combination
2	Always available but with a value equal to 0 if no LTMEV40 is connected
3 - 9	Not used

If the Note Is...	Then...
A	The variable can be written only when the motor is off.*
B	The variable can be written only in configuration mode (e.g. static characteristics).*
C	The variable can be written only with no trip.*
D - Z	Not used

Unused Addresses

Unused addresses fall into three categories:

Not significant, in Read-only tables, means that you should ignore the value read, whether equal to 0 or not.
Reserved, in Read/Write tables, means that you must write 0 in these variables.
Forbidden, means that read or write requests are rejected, that these addresses are not accessible.

Data Formats

Overview

The data format of a communication variable can be integer, Word, or Word[n], as described below. For more information about a variable size and format, refer to Data Types.

Integer (Int, UInt, DInt, IDInt)
