To finetune the PID-loop, you can use the PID tuning control panel, you find it under tools. To use the autotune function, bring the PV close to the SV manually and then start auto tune. To be able to use the control panel PID init has to be called and downloaded to PLC. Attached some screenshot to show the digital output and the Control panel.
