Hi All,
I have a RS500 program for a wine pump. In manual the pump is running too fast and I need to slow it down, sounds pretty easy. PLC talks to a touchscreen that provides a setpoint for the speed reference (N7:0), for some reason teh PLC then multiplies this by 164 to then create teh speed reference. In auto the PLC gets a signal from a level probe that it then divides by 164.
I am assuing I need to modify the manual multiplication factor but I am curious as to how they got the 164 and I don't really want to play with this unless I now why this number.
Any ideas would be appreciated.
Cheers
Peter
