Write to PLC Connect Boolean Tag from ABB800xa
I think I didn't explain well in my previosus question, apologies for that.
Can you please let me know if i need to do anything apart from enable "IS Controllable" check box under particular tag under PLC connect to write data to it from ABB800xA SCADA or control structure?
I am able to read all data from PLC connect and displaying that on Graphics in ABB800xA but in this instance I want to write to PLC connect boolean tag from ABB800xA, Can you please guide me on how I can achieve this?
I have checked 3rd party OPC property and thats set to "RW" access which makes me think I should be able to write to that tag from ABB800xA.

Have you checked if the write is rejected or return an error?

What PLC is in use? How do you connect PLC Connect to it? Via OPC? Have you attempted to post a write using a 3rd party OPC DA client connected *directly* to the destination OPC DA server?
Thank yo so much for your help. I manage to resolve the issue without using property definition transfer aspect. You were correct that "IS Controllable" checkbox enable is enougg to write data to PLC Net from ABB800xA Scada. The issue was with with OPC permission thogh it was showing "RW", it wasnt accepting data from ABB 800xA, I had to reconfigured OPC server for the PLC then it allowed me to write data from ABB800xA.
Thank you so much for your help, its really appreciated.
