Status LEDs
The LEDs are located at the front of module. There are 2 different groups:
- The 5 system LEDs (PWR, STA1 ETH, STA2 ETH, S-ERR and I/O-Bus) show the operation status of the module and display possible errors.
- The 29 process LEDs (UP, UP3, inputs, outputs, CH-ERR1 to CH-ERR3) show the process supply voltage and the statuses of the inputs and outputs and display possible errors.
