Basically in CASCADE control, there are2 controllers. One is MASTER control and other is SLAVE control. For example if we want to control temperature in H/E, we have temperature control as MASTER and FLOW CONTROL VALVE on steam line as SLAVE control. Now to take CASCADE in line, put MASTER on AUTO mode with desired SV( set value) and put SLAVE ( here in our case Steam control valve) on CASCADE mode. That is all.
