8.6 Interfaces
The COMPAX interfaces for data and status are digital inputs with an PLC data
interface, an RS232 interface and an optional bus interface (interbus S, CAN bus,
CANopen, profibus, CS31 or RS485).
The RS232 interface can be operated simultaneously with other interfaces.
8.6.1 Digital inputs and outputs
To control the program process, 16 inputs and 16 outputs are available (8 inputs
and 8 outputs with COMPAX 1000SL).
O7-O11 and I7-I11 are assigned when the PLC data interface is switched
on.
