Hello,
I have a machine infront of me with two HMI PanelviewPlus 7.
They are the exact same, and the hope is to use the same MER file for both to keep it simple.
I usually have a tag in the HMI file that writes the current screen to a tag in the PLC. This is helpful if the operator is doing some next level adjustment (part setting changes, Date and Time change, etc).
Having two HMI running the same MER file, I'm noticing the HMICurrentScreen tag I have wont really work, since both HMIs are writing to the same tag, most likely will be overwriten.
Normally, I would just create a second MER file, but i'm trying to avoid that here. Would like the MER or FactoryTalk View Studio to know which HMI it is, and possible send to a different tag based on which HMI the MER file is running on...
Both HMIs and PLC communicate over Ethernet.
