4�9�2� PROTOCOL

The Modbus protocol is an industry communication standard which enables networking of

multiple units, with one master and several slaves. It allows individual master-slave dialogue

and also enables commands in broadcast format.

In the Modbus protocol, the

Controller MASTER control VAR FAST

unit uses the RTU

(Remote Terminal Unit) mode.

In the RTU mode, the message start and end are detected with silences of at least 3.5

characters, and the 16-bit CRC error-detection method is used.

The Modbus

functions implemented in the unit are as follows:

Function 01

. Reading the status of the relays.

Functions 03 and 04

. Reading logs.

Function 05

. Writing a relay.

Function 0F

. Writing multiple relays.

Function 10

. Writing multiple logs.

Exception codes

If the bit with greatest weight of the byte corresponding to the function in the reply of the unit

is 1, this indicates that the next byte is an exception code.

Table 11: Exception codes, Modbus communications�

Exception code

Description

Incorrect function. The function number is not implemented.

Incorrect address or number of logs out of limits

Data error. A CRC error has occurred

Peripheral error. An error occurred when accessing a peripheral (EE-

PROM, card, etc.)

Slave error or Slave busy. Retry sending.

Example:

Address

Function

Exception

code

CRC

0 A

XXXX

Address: 0A

, Peripheral number: 10 in decimal.

Function: 84

, Reading function 04 with bit no. 7 at 1.

Exception code: 01

, see

Table 9�

CRC:

16-bit CRC.

For reasons of operational security of the unit, communication frames of

more than 80 bytes are not accepted (sent or received).
