DEAR EXPERTS,
AM USING PCS7 V6.2 IT SHOWS TAG NOT EXIST ERROR IN DIAGONISTIC SCREEN I ATTACHED THE SCREEN SHOT.KINDLY FIND IT AND GIVE A SOLUTION TO CLEAR THE ERROR.

Dear phantom,
Normally its working is fine.Actually my system is hanging frequently.So i thought will put diagnostics for checking error in screen.So i put diagnostics in the screen after that i check all the block icons individually at that time it shows this error in diagnostics screen.Its a faceplate of siemens only.
