So when going through creating logs of all our safety signatures for tracking purposes. I found one PLC without a safety signature. This one is also kind of setup weird where the Standard PLC logic, and Safety PLC logic are in two completely seperate PLC files.
I figured no problem, and tried to generate a safety signature, and soon as it got done uploading the signature the PLC faulted and completely lost the PLC program in the PLC. So I redownloaded the program and immediately same thing, PLC faults and loses program. So in the offline file, I deleted the signature and redownloaded and all good. Tried to generate signature again and boom PLC faults and loses program.
Anyone got any idea why this is? I assume it has something to do with the standard PLC logic and safety PLC logic being in seperate files...It's only losing the safety program. I can actually still go online with the standard program.
Thanks.
