My less educated, speculative guess is that you had to re-add it because you realised it was used somewhere and the program wasn't happy without it ) Once the screen has changed, you need to write the Remote Display Number tag back to zero in the PLC, so that it releases control of the display back to the operator My educated guess would be that the status_screen tag is defined in your global connections as the "Replace Display Number". If you are doing this, be careful - while the PLC is commanding the HMI to go to a certain screen, the operator cannot choose a different screen. The Remote Display Number does the opposite - if your PLC writes a "5" into this tag, the HMI will show the display with ID 5. If the the operator switches from screen 1 to screen 2, the HMI will change the tag in the PLC from 1 to 2. To take an educated guess at what it's there for, in your global connections you have two tags that you can assign that work as follows (copy and paste my post from another forum): The "Replace Display Number" is the ID number of the current "Replace" type display that the HMI is showing. All I can tell objectively from that screen is that it's an analog tag which reads from or writes to N107:25 in whichever PLC is defined by the "dcm2" shortcut. ![]()
