Project: I created new single project with WinCC v7.0 SP3 and added some binary tags under MPI (which is configured to PC adapter(MPI)).
Then I opened up Graphics Designer, created circle, under Colors right clicked on Background color, Dynamic dialog, selected one of tags for expression, selected Boolean Data Type, replaced colors for ON and OFF state.
Problem: when I click on runtime mode, circle simply won't change it's color, but instead stay gray. I've tried to change several other settings, but without any luck. It simply doesn't work and I have no idea why. Did I miss something? Where's the trick?
