Each of the 8 combination I/O channels can be used either as an input or an
output. This means that both an input address space and an output address
space are reserved for the process map in the bus coupler. A channel used as an
input(e.g. initiator) cannot be used as an output channel at the same time,
however, an output can be inverted to an input. This way the PLC can monitor the
switching function.
Note on modules with digital combination channels that it is not allowed to connect
a 24 V supply to a combination channel without feeding in the power supply.
Otherwise the power supply will be fed back over the output circuit of the
combination channel to the power supply terminal of the module which may result
in a malfunction or destruction of the output circuit.
