Ok so I am new at all this and I am sure I am doing something wrong so that’s why I am asking yall.
So I created a momentary push button that when pressed will latch in an output in the PLC that controls lights. So I bound the Control Value to a PLC tag called hmi_LightsOn. When I press and hold the button I can see the Control Value change to 1 and remain 1 until a let go of the button but the tag in the PLC never changes. If I change the tag to be bidirectional under the options of the button it works though. Any idea what I am doing wrong?
