The table can represent when we set controller to manual. Then can change the value of %CO which have affect to the process
The table can represent when we set controller to manual. Then can change the value of %CO and Remote SP which have affect to the process.
The experiment uses the PID controller to control the level of tank. In the first we draw the P&ID form the real level process control and convert it to block diagram.
The PID tuning for cascade control must to finish tune the secondary loop(slave) before going to tune the primary loop(master).So the sensor at primary loop will measure disturbance of process and sent remote set point to secondary loop for control inner process.
