I am controlling a fan and measuirng the flow. Everything else works fine, I managed to controll everything over Free Telegram, PI controller is in VFD and I am sending setpoint over Profinet . Feedback is over analog input on VFD. Also I managed to transfer all relevant data from VFD to PLC. But I am struggling to find solution to change KP and KI paramters from PLC directly to VFD. Thank you in advance.
