structure.
Data Type: Float
The error (SP-PV) used to determine the control
action.
Data Type: Float
The working set point of the block after limiting
and filtering is applied. EU of PV_SCALE
Data Type: Float
The time constant of the first‐order SP filter. It is
0 the time, in seconds, required for a 63 percent
change in the IN value. Applied after SP rate
limiting.
Data Type: Unsigned8
