Your input_PER should be IW0 instead of QW0? Your output also seemed to saturate at 100%. So the feedback loop did not appear to be closed.

😂😂😂. Simulation doesn't work properly on this kind of process controls. Please do it with real actuators with feedback and you see the power of PID. Also addressing input n output uses QW. In Sim, you can use MW. In actual PLC you use IW for input(process value) and AQ for Output..
