4.3 FCO103 - External Set Controller with Tracking Local Setpoint
Factory Configured Option FCO103 provides a single loop controller with external setpoint configured in Loop01.
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.
