I am very used to mapping IOs in TwinCAT where you need to declare your variables with AT%I and AT%Q. In Codesys, you can map a physical IO to any variable, but is there a way to declare variable that are expected to be mapped to IOs so that I could filter them out in the mapping dialog?
Or maybe I should just use some kind of naming convention for those variables like: IN_myInput and OUT_myOutput.
I would like to know how others are mapping IOs to variables.
Thank you.

I use seperate global variable lists for inputs, outputs, and fieldbus. I also use my own naming conventions in addition to using x or w as a prefix to indicate boolean or word.
