Hello guys, 

I want to control the VFD G120 (start, stop, forward, jog) via Profinet but I  also control the speed of

VFD via a potentiometer connected directly to analog input of  the VFD. I will use telegram 1 and

SINA_SPEED block. 

Could you tell me what needs to be done to make the Profinet  and the potentiometer work at the

same time? I have found a video and a Siemens example application on how to control the VFD using

the SINA_SPEED block, but I also have a potentiometer. 

Thanks a lot. I am new in PLC and I am learning  with no real help step by step on my first real project.
