How To Create a Pop Up Display Triggered by Change of State in FactoryTalk Studio ME

[JKanyce]

I need to add a pop-up display to an existing PanelView Plus program. However, I'm not understanding what I need to do with the Global Connections and Macros.

Say I have a tag named 'var.' If var changes state from 0 to 1, I want a "pop-up" display to appear. I want this pop-up display to appear "on top" of any of the other display screens whenever the state of var changes from 0 to 1 regardless of what screen is currently displayed on the HMI.

It seems like it should be fairly simple, yet I cannot figure it out. Any help would be greatly appreciated.


*This is for FactoryTalk View Studio - View Machine Edition

Any help would be greatly appreciated.

Macros are not necessary, just global connections.


Create your display, setting it as 'on top' and giving it a unique display number.


In Global Connections set an integer tag (let's call it 'HMIDisplayTag') for 'Remote Display Number'. In your PLC program, when your 'var' tag changes from 0 to 1 then move the value you set as the display number into HMIDisplayTag. This will trigger the HMI to open the display with that number.


Make sure to move a zero back into HMIDisplayTag, as having anything other than zero in it prevents the operator from changing screens at the HMI.

Thanks so much! You provided a simple explanation and that's all I needed.
