Please help,

That is what I did, started the machine with the new one, the buttons stopped blinking and it was OK for few seconds, and after that ...same thing... I've used the ghost image after with the new panel and it was working like this for 2 shifts, and then after a break of half an hour ... started fine, made the program reference for the clamps ... and went blinking again ,....

Battery voltage should be around 3.6V..lithium battery... try connecting your Simatic Step 7 tool andcheck in the PLC why are you getting this error in the diagnosis. Regards, Prakash
