Hello Everyone,
I've recently been given an assignment for a PLC project that requires a PID loop being implemented to control the flow rate on a pump. In the course of the program there will be times that I want the PID2 function block to not be processed so I can maunually set the output value. My question is: does the top input to the function block, the Auto/Manual input do this, or is this input used for something else. This is my first PID implementation, and don't have the equipment in house to test with. Any help would be greatly apprecialted.
