Hi,
I am trying to automatically regulate a process ( liquid ) in a tube using an ultrasonic sensor, differential level meter, control valve, and VFD with motor & pump. My question is, can I cascade two PID’s in RSLogix 5000 to control this process and would it work ? For example, if I had the master PID using the ultrasonic sensor to control the valves and the slave PID using the differential level meter to control speed of the motor. Will this setup work ? I am new to using PID’s in RSLogix 5000 so I apologize in advance if I am making any simple mistakes.
Kind regards,
24V
