Hello all dear 

my project is PCS7 8.2 and with wincc 7.4.

I installed SP1 for wincc 7.4. Therfore WINCC software upgrade to WINCC V7.4 SP1.When compile OS Server with check box entire and then activate wincc. Interlock faceplate and permision faceplate doesn't work in motor faceplate. and buttons are disable. 

Why do interlock faceplate's button and permission faceplate's button disable in motor faceplate?

Thanks for help  

Check the CFC chart that is linked to that faceplate, it could be possible that channel drivers might not be generated for that block icon or the logic (i.e. OR or AND) which enables the interlock might not be fulfilled.
