1. MODBUS

PROTOCOL

The MiCOM P225 relay offers MODBUS

RTU mode communication via a rear RS485 port.

1.1 MODBUS

communication

characteristics

1.1.1 MODBUS

network

characteristics

The MODBUS protocol is based on the master-slave principle with the MiCOM P225 relay as
slave.

The MODBUS protocol allows the master to read and to write one or several bits, one or
several words and to remote the event logging data.

The access to the network can be :

−

either according to a query/response principle

Equipment

Slave

Equipment

Slave

Equipment

Slave

Response

Query

Master

P0211ENa

−

or according to a broadcast message sent from the master to all the slaves.

Equipment

Slave

Equipment

Slave

Equipment

Slave

Broadcast

message

Master

P0212ENa

in that case :

−

compulsory, the broadcast message is a writing order,

−

the slaves return no response,

−

the protocol is RTU mode. Each byte of the data frame is coded according to a
hexadecimal base.

−

At the end of each frame, two bytes of CRC16 validity checksum are applied on the
whole of the frame content.
