4.9 FCO122 - Cascade Control w/ Operator Setpoint Limits
Factory Configured Option FCO122 provides two loops configured for Cascade control. The block diagram of the
configuration of the two loops is shown below along with the
changes
made to the default parameter values of the
configured blocks. The process range of the Primary loop can be changed in Analog Input 1 and the range of the
Secondary loop in Analog Input 2. Also, the output range of the primary PID controller must be changed to match
any new range in the secondary loop. If the loop tag ‘PRIM’ or ‘SEC’ is changed, all configured references will
automatically be changed to the new tag.
