On my G3/AX system, I have some OPC boolean points brought in. The read-only points seem to operate correctly (as they indicate the correct values and change when they are supposed to change), but on the Boolean Writable points, the "Write Value" never seems to get written out. When I look at the point, I can see that the "Write Value" is set to True, but the "Read Value" stays at false.
What am I missing?
I can successfully toggle this point from an external OPC client.
I can't even force the point from within workbench. If I right click and select Actions->Emergency Active, I see that In1 goes to True, but Out and Read Value stay false, the same as if I try to control the point from my normal in10 input.
Attached is an image showing the point when it was set to "Emergency Active". You can see that In1 is True, but the Output and Read Value remain false....
