Split from Potentiometer usage with S7 300 I/O.

Hello,

if you want to use a potentiometer fro speed control then you need a Analog IN card, e.g. 6ES7331-7KB02-0AB0 or 6ES7331-7KF02-0AB0.

Then can you calculate the position of the potentiometer for your speed control.

If you want to use this only at WinCCflexible then you could also use a slider and the position of them as value for the PLC (e.g. 0...100 %)

I hope this helps.
