I wonder why FB for such a small and simple task?
As long as the program memory allows, I would simply rewrite it as many times as necessary, in the main program.
FBs are data memory and scan time significant consumers.

i did this for simpler appearance, i make this program at home and i cant be on actual site to adjust these parameters and the technician that will adjust this doesn't have enough knowledge on this matter, and i don't want him to mess around the program. its easier if it only have hmi.
