Digital common lines for X7 and X8 are not common to each other.
The DCOMx line should be connected to the 0V of the I/O supply when using sensors of type "Source" with digital inputs.
The DCOMx line should be connected to the 24V of the I/O supply when using sensors of type "Sink" with digital inputs.

Connector X9 (all AKD variants)

If X9 is not used for second feedback input or EEO, it offers three RS485 channels which are programmable as digital outputs.
