Hi,
I am trying to download program into PLC but old and new program have diff safety signatures. I guess I am supposed to unlock PLC and delete current safety signature so I can download new program.
But when I put controller into program mode, safety lock/unlock button stays in light grey area means I cannot unlock PLC to delete current safety signature.
Replacing controller is my last option but is there anything am I missing or need to do in order to unlock controller? Attaching screenshot of controller safety.
Thank you
