How do you execute speed or tension calculations in a PLC? Do you use a STI (Periodic task) to make sure the calculations are executed at the same intervals every time?
I am thinking of using an Event driven task to make sure that speed and tension loops are updated every xx.x feet of the line.
We have several machines in house that just run continuous task and don’t make any efforts to handle things consistently. Does it really matter? I don’t know if it does but in the theory I think it should.
