Hi all. Can anybody help? I am new to S7 and have been thrown in at the deep end. I need to look at a couple of analog inputs and drive an analog output depending upon the input values. Can someone please provide some sample code that shows which blocks are used and how the signals are handled?
I did the Step7 training course awhile back, but PID's were not covered.
(I need to control a pump speed to maintain a constant level in a tank.)
Many Thanks [email protected]
