Anyone experience of working with these modules and interrogating status of an I/O port?
The modules can throw up a red LED indicator to say an input or output is in a fault state, but I haven't been able to find how the controller can identify this.
It would also be useful to know when the power for the input side or the output side has dropped out.
Any help much appreciated.
Mark..
