Simcet is a dynamic real-time simulation software for PID tuning in DCS and PLC. It provides the user with real plant-like environment on a PC platform. Simcet is designed to train, test, certify and qualify process control engineers, technicians and operators before allowing them to tune loops in the control room. Users see PV, PID output on the screen in real time. User can change SP, see the effect of tuning changes on control quality.
