Okay so I am using Factory Talk Studio 8.1 and am having a hard time figuring out how to use a parameter file to control the visibility of a button. I have 4 different parameter files and tried having the place holders control the visibility of each of the buttons so that when they are clicked they cannot be clicked until another parameter file is loaded. Example visibility: #1=1 visible. This comes up with an error "expression contains a tag that has an error value: #1=1". I am trying to do this so that the popup does not come up saying "GoToDisplayButton's requested display is already open". I know there is a parameter file tag in the global connections that could be of use but I'm not sure if the HMI writes to the PLC or my guess is that it only reads from the PLC. Any ideas?
