MODBUS COMMUNICATION PROTOCOL FOR M-3410A

When the appropriate communication interface hardware is connected and the proper initialization of the communication options

is complete, the data defined herein can be accessed and modified by remote communications.

This document describes the implementation of the MODBUS protocol as it relates to the M3410A IPS control.

The M-3410A may be programmed to support a subset of the MODBUS protocol. The following restrictions apply:

1. MODBUS protocol is supported on COM1 (front RS232) and COM2 (rear RS232/RS485).

2. Parity and Stop bits are supported, valid selections are [8,N,2], [8,N,1], [8,O,1] or [8,E,1].

3. Only RTU mode is implemented, ASCII mode is not supported.

4. Standard baud rates from 300-19200 are supported.

5. Only the following 6 MODBUS commands are supported: 1) Read Holding register (Function 03) 2) Read Input register (Function 04) 3) Force Single Coil (Function 05) 4) Preset Single Register (Function 06)

5) Preset Multiple Registers (Function 16) 6) Diagnostic (Function 08 – Subfunction code 00, 01, 04) No more than 120 contiguous registers should be read with one request.

No more than 16 contiguous registers should be written with one request.

Read Holding Register (03) is identical to Read Input Register (04) and reads the same data.

Force Single Coil (05) is identical to Preset Single Register (06) and writes the same data.

Force Single Coil (05), Preset Single Register (06) or Preset Multiple Registers (16) is used to write to register(s) defined as

writeable.

Diagnostic (08), Subfunction code: (00) – return query data, (01) – restart communication, (04) – force listen only mode.

The following exception code are implemented:

ILLEGAL FUNCTION 01

ILLEGAL DATA ADDRESS 02ILLEGAL DATA VALUE 03

SLAVE DEVICE BUSY 06

SLAVE DEVICE BUSY is returned if control is in the local mode.




Register addresses in this document are actual addresses in the device. For examples:Address 2000, in 3x reference (Read Input Registers) will be 30000 + 2000 + 1 = 32001.

Address 3000, in 4x reference (Preset Single Register / Preset Multiple Registers) will be 40000 + 3000 + 1 = 43001.

Register content is a two-byte data word and is transmitted and must be received most significant (high-order) byte first.

Communications is effectively half duplex in that a request packet is transmitted and a response packet received. Further requests

should not be sent until the previous packet response is received.

The following definitions apply to the data table in this specification:

“SCALE FACTOR”: the factor by which the register content read from the control is divided to get the value of the variable in theindicated “UNITS”.

Unless otherwise noted all data registers return 16 bit signed integer value.

Registers marked with a (U) appended to the scale factor field should be taken as unsigned values (0-65535) before scaling.

“UNITS”: unit of the register content

“ATT”: attribute of the register (W indicates writeable, and F indicates factory writeable only. All registers are READ_ONLYunless noted otherwise).

“RANGE/INCREMENT”: valid range and increments of the register content for WRITE commands. Consult the control

specification Sheet for unscaled setpoint ranges and increments.

“DESCRIPTION”: register content description.

To be revised

All voltage, current and power metering values (see TYPE 1-XXX status points) are returned as secondary values(I.E. 120V

5Ampps). These values need to be scaled by the proper C.T. and/or (V.T.) ratios to obtain an equivalent primary quantity. Also, the

VT configuration needs to be considered to obtain the proper primary reading.

Ex:Reactive power

Given:C.T. Ratio 240 : 1 (1200A : 5A) Communication point 3-xxx returns

240

V.T. Ratio 100.0 : 1 (12Kv : 120v) Communication point 3-xxx returns 1000

V.T. Configuration Line to Line Communication point 3-xxx returns 0

Nominal Voltage 120V Communication point 3-xxx returns 120

Nominal Current 5.00A Communication point 3-xxx returns 500

Reactive power -1.2348 PU Communication point 1-44 returns 65535

Communication point 1-45 returns 53188

(-12348)

If V.T. configuration Line-to-Line or Line_Gnd-to-Line_Line

Primary reactive power = 1.732 * C.T. ratio * V.T ratio * Nominal Voltage *Nominal

Current * Secondary reactive power

Else if V.T. configuration Line-to-Ground

Primary reactive power = 3 * C.T. ratio * V.T ratio * Nominal Voltage * Nominal

Current * Secondary reactive power

-30796899 = 1.732 * 240 * 1000 / 10 * 120 * 500 / 100 * (-12348) / 10000

Note:

1. Relay Error Recorder Modbus interface:

User issues Modbus read at register 1340. 0 => no relay error record; 1 => at least 1 relay error record.

User issues Modbus write with a value of 1 at register 1341 to request the first available relay error record.

User issues Mobus read at register 1341 to poll for relay error record ready status. 0 => not ready; >1 => record ready; 65535 =>

no more.

User issues Modbus read at register 1342 to get the relay error total if desired.

User issues Modbus read for 5 registers at register 1343 to retrieve the relay error record when relay error record is ready.

User issues Modbus write with the value returned from the previous Modbus read at register 1341 (1< n < 65535) at register

1341 to request the next relay error record. Repeat the polling/requesting sequence until no more relay error record.
