4.6 FCO106 - Single Loop Controller w/ Operator Setpoint Limits
Factory Configured Option FCO106 provides a single loop controller configured in Loop01. This is similar to
FCO101 but with a SPLIM block added to the output of the SETPT block. A block diagram of the loop
configuration is shown below along with any changes to the default parameter values of the configured blocks.
This configuration provides setpoint tracking. If a fixed setpoint is desired, the TC input to the SETPT function
block can be set to UNCONFIG. If the loop tag ‘LOOP01’ is changed, all configured references will automatically
be changed to the new tag.
