Station address
This address is used to identify the PLC in bus or modem operation. In a system, each controller

Baud rate
The baud rate setting refers to the transfer speed between the Modbus instruments.
Control system monitoring
Any intervention made by the control system on dynamic processes are restricted in time, pro-
vided that communication between the control system and the controller is not established. The
controller resets the time monitoring after every valid retrieval of the station address. After the
defined maximum time has elapsed, all even bits are reset to "autonomous".
