PID1 Mode Selector
(14.059) can be used to select the feedback and error as shown in the table below. It should be noted that PID controller 2 will
operate normally even when its feedback or error has been selected for PID controller 1. However, if
PID1 Mode Selector
(14.059) is non-zero PID
controller 2 enable is controlled directly by the enable state of PID controller 1.

PID1 Feedback Output Scaling
(14.058) can then be used to scale the results.
PID1 Feedback Square Root Enable 2
(14.062) can be used in
converting the output of the combined feedback from pressure to flow. It is easier to use a pressure transducer than a flow transducer, and so the
feedback from the transducer needs to be converted from pressure to flow. As flow = Constant x √Pressure the square root function can be used in the
conversion.
