I'm working on a project to convert an old PLC5 processor to an L63.
Below is sample logic of one of the several PID controls from the conversion. In other places, the PID control has no permissive or timers and just executes every scan.
The loop update time is set to 1 second on each of these blocks, even though they're scanned continuously. I believe their process works as is, but without some sort of rework and re-tuning this conversion will mess everything up (since the scan times will be MUCH faster).
Do you think putting this logic in a periodic task with the same period as the average PLC5 scan time will work?
Do you have any tips or can you point me to tips for this sort of conversion?
