The function block application which might be configured for this application is shown below. In this
case the National instruments configurator has been used.
This dialogue box is used to adjust the scaling of the
parameters supplied to, or derived through, the
processing of the control loop.
In the block diagram of the PID function block, these
values can be seen and their relationship to the control
algorithm.
The choice of the correct scaling and engineering units
is important in the correct operation of the block.
If (NULL) is being shown the FF CP card is not
receiving data from the actuator control PCB, possibly
due to the actuator being powered off.
