Posted 25 Mar 2016 I am working on project which is using Micrologix 1400 and AB Panelview. I am using FactoryTalk View Studio to build the HMI. The PLC needs to know which screen is displayed on HMI so some additional functionality can be activated. How would this be done? I was looking where could I write screen number to N7 location in the PLC or set a bit in B3 area but could not find anything. Thanks for your help. Share this post Link to post Share on other sites
Posted 25 Mar 2016 By default the screens do not have numbers. In the Display Settings you can assign each screen a Display Number. Then in the Global Connections, Display tab, you can assign tags to read and write screens. Share this post Link to post Share on other sites
