When programming in RSLogix 5000, I usually map all my inputs to bits to be used in the program. Since the IO is updated separate from the program scan, it could lead to Inputs or Outputs changing mid scan, and could cause unexpected or undesirable results with the logic.
The downside of this, is that you can not force the IO from the point of use in the program.
Unless I am mistaken, A tag aliased to an input is updated at the same time as the actual input, right? Not once per scan like a mapped bit in the logic would be?
Is there a way to make a non-aliased tag force-able?
