hi there..
i am using siemens plc s7-313c..what's my problem??
i'm working on a project trying to control pneumatic valve with pid and levitate some objects...(airflow levitation)
i have a 4 sensors, each one helps me know exactly where my object is, so the valve should give more or less air...(object goes up or down )
analog inputs: PIW752-->sensor1 PIW754-->sensor2 PIW756-->sensor3 PIW758-->sensor4
analog output: PQW752-->valve
i try to use pid FB41 but...always something is wrong and nothing works..
please can u help me with all these parameters at FB41..
thanks ...
