Description
Enable input. If false, the instruction does
not execute and outputs are not updated.
Default is true.
The analog signal input to the instruction.
Valid = any float
Default = 0.0
Maximum output increment rate in per-
second units. If invalid, the instruction sets
IncRate = 0.0 and sets the appropriate bit
in Status.
Valid = any float 0.0
Default = 0.0
Maximum output decrement rate in per-
second units. If invalid, the instruction sets
DecRate = 0.0 and sets the appropriate bit
in Status.
Valid = any float 0.0
Default = 0.0
Request to bypass the algorithm. When
true, Out = In.
Default is false.
