State LEDs
The LEDs are located at the front of module. There are 2 different groups:
●
The 4 system LEDs (PWR, CS31, S-ERR and I/O-Bus) show the operation state of the
module and display possible errors.
●
The 26 process LEDs (UP, inputs, outputs, CH-ERR2 to CH-ERR4) show the process
supply voltage and the states of the inputs and outputs and display possible errors.

With "Module" the following allocation applies:
31 = Module itself; 1...7 = Expansion 1...7
In case of module errors, with channel "31 = Module itself" is output.
Ch = 14...21 indicates the digital inputs/outputs DC8...DC15
Ch = 8...11 indicates the analog inputs AI0...AI3
Ch = 12...13 indicates the analog outputs AO0...AO1
