RS232 and RS422/485

The serial interface is implemented using two different additional cards for the central process-

ing unit. The type of the used interface board, RS232 or RS422/485, is automatically detected

by the central processing unit via the hardware ID.

In Modbus slave operation, these interfaces can be used to connect visualization software and

also for Modem connections.

External process values can be read in during Modbus master operation (no modem opera-

tion). This way, you can increase the number of input values.
