I don’t understand this answer, why creating a folder?
If I understand correctly, I’m comparing an integer with a bit and that’s not possible but I’ve tried to change the type and data type of tag1 to Analog and Integer, but the same error appeared.
3rd: would it be possible to use this expression, (I’ve tried but got the same error msg):
Being that this is a digital tag, just select the tag in the "expression" textbox don't add any other "logic" - just the tag, then select the color you want for the on state and the off state below.
Your "expression" has a minimum of three states 0, 1, and not 0 or 1. That is not possible with a digital tag....
