help with Logistat A500


Thread Starter


Hi all,

I work in a company where we have an old automation equipment based on two AEG Logistat CP80-A500 PLCs. It's become unresponsive after a power failure. This is, you cannot interact at all with it through any of its inputs, and its output modules (DAP 112) remain disabled after the failure.

Each PLC has a UKA 024 monitoring module, the LEDs of which remain as follows: "Betrieb" and "SUE" off, and "Zykl" on.

Does anybody know if there is any way to find out what's going on in the controllers? Any tool to diagnose any possible failure or just read the program status?

This equipment is quite old and the little documentation available is in German, which none of us in the company speak. So any help would be much appreciated.

Thank you in advance.
