Does anyone have some control position of a hydraulic cylinder samples ?
i'm trying to control the mouvement from a point A to a point B of a cylinder with an analogue trasdoucer of position for have the position and driving a proportional valve with a signal 0-10volt . but i'm having some problems for create a trapezoid profile .
I'm using a s7-313c .

Thanks in advance
