HA AC500 V3 Digital Outputs are not working!
I have an HA AC500 V3 system as attached in the photos! Two redundant CPUs and two CI521 clusters with multiple IO modules! I can read the inputs (DI and AI), but I can't energize the hardware outputs!
The outputs are declared and called only once in the application! In addition the outputs light up in the program but not energized on the PLC?
I check the wiring for short circuits and other wiring mistake but I did not find any!
Could you please help me to solve this problem! It is really urgent!
The application is also attached!
I can recommend to check the HW configuration of the modules (DA501):
make sure you placed the variables to Digital Output DC16...DC23 fields and not to the input channels fields of the module.
Try to disable "Detect on short circuit at outputs".
Check 24VDC on UP and ZP at all terminals of the module.
Try with a new (clear) variable, connected to one DO channel.
