Activating internal digital when display page changes.

Keith Boone 4 years ago in IQANdesign updated by Gustav Widén (System support) 4 years ago 2

Is there a way to active an internal digital channel when a current display page changes? I have an application where a function needs to be turned off anytime that the operator leaves the respective operation screen. There are multiple operation screens with this function.

we've done this before using a system information channel, set to 'active display page' this will give a numerical value based on what page is up, and you can then run it into logic.

In addition to the system information channel for active display page that David mentioned, you may also want to monitor Menu system open using a second system information channel.

In case the operator is able to enter the menu system from that display page, the active display page will still be at the value it was when entering the menu system, so then it is good to monitor both.
