Cascade Control Loops
Looking for help with cascade control loops

I have two slave controllers and one master controller, but one final element. I have the P&ID and I want to know how these loops work.
Any experience? How the slave controllers' setpoints are defined?

Slave controllers receive their process data signal from a another controller.
