Master-Slave-Arrangement

Configuring the Master

To configure the CM574-RCOM as a master device, the parameter “Operation mode” must be set to “RCOM+ Master”. The address or node number must be set to 0 while “Parity” is set to “Odd”. All other parameters can remain default.

If the CONSOLE port is used (recommended), the parameter “Debug level” of module “CONSOLE” should be set to “Level 2” to obtain detailed information and error messages of the protocol.

Configuring the Slave

To configure the CM574-RCOM as a slave device the parameter “Operation mode” must be set to “RCOM+ Slave”. The parameter address must be set to a value greater than 0. In this example select 1 for the slave. “Parity” is set to “Odd”. All other parameter can remain default.

If the CONSOLE port is used (recommended) the parameter “Debug level” of module “CONSOLE” should be set to “Level 2” to obtain detailed information and error messages of the protocol.
