26 Motor control and protection unit | M10x parameter discription
Modbus communication
The communication function provided by M10x-M is based on Modbus RTU. The
fieldbus interface is RS485. There are two identical RS485 interfaces, for redundant
design. Parameterization, remote control, data acquisition and transmission etc.,
are implemented via the communication function.
For more information on M10x-M communication, please refer to M10x User Guide
and Modbus Protocol Implementation for M10x-M.
The parameters involved with the protection function are:
Device address
Parity check
Redundancy
Modbus baud rate
Device address
Function
: COMMS
Range
: 1-127
: 1
Default setting
Related parameters
: -
Description
:
Each M10x-M on the same serial communication network must have a unique
address in the range of 1 to 127. Computer software driving the serial network must
be configured to recognize each separate address.

Function
: COMMS
: Odd/Even/None
Range
Default setting
: None
Related parameters
