1204 COMMUNICATION ERROR (I/O MODULE) [0000_0000_0001_0000]
In last time this message appear on a DX100 controller, like a major alarm. After restart, for a while no problem, until the message appear again with
[0100_0000_0001_0000] or [0100_0000_0000_0000]
In the alarm list manual they say:
The communication error slot (Serial-busconnected I/O module communication station No) is displayed by the bit.
0: correct / 1: incorrect
I don't understand how i find the module with problem from this code [0000_0000_0001_0000]
Can someone help me understand?
Thanks.
