Hello, hope yall are doing well. I have a HMI program where I need to add a "GoToDisplay" button, so when this button is pressed, it goes to a different display. However, I only want this button visible when my boolean tag = 1 on the PLC side. For the expression, I have (hmichipcollectormsg). I have the visibility box checked also and expression true state is set to visible. My tag is equal to 1 on the plc side. I noticed some of my tags which are controller tags have [PLC1] in front of the tag name, so I also tried [PLC1](hmichipcollectormsg) as the expression, but this did not work.
Do I need to import this tag into view studio ME first before I can use it? I'm using View studio ME v13. I rarely hook up to program this HMI, so I cannot remember if this step is necessary. Anything else I can try? Thanks!
