I am using Compactlogix PLC and Zenon Editor Version 7.50 for my application.
I created the driver and I am able to import variables from PLC. However, when linking some variables from a PLC AOI to momentary buttons I got red dots in the buttons right side.
When I link variables that do not belong to AOI it works perfectly.
I wassaw on the help content that the red dots means problems with communication, thought I can not understand it only happens when using variables from AOI.
Please, could you help me with this?

Kind Regards,
