I own a Lagun Republic CNC Mill with a Siemens Acramatic 2100
Touch Screen Control, mfg date 2000. Since some time now, error
message "System Fail 8004d "Realtime Timeout, cause= workstation msg thinks realtime is not responding"comes up and shuts the machine power off.
I already tried to disconnect and re-seat the Workstation and Realtime circuit boards but this does not solve the problem. Please advise if you can tell me which board is defective and if I can send it to you for test and possible repair (including changing the battery without losing any data).
I am not a expert in electronics and would appreciate any help you can offer since I need the machine back running soon.
