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
Request to initialize filter control algorithm.
When true, the instruction sets Out = In.
Default is false.
The lead frequency in radians/second. If WLead <
minimum or WLead > maximum, the instruction
sets the appropriate bit in Status and limits
WLead.
Valid = see Description section below for valid
ranges.
Default = 0.0
Order of the filter. Order controls the sharpness of
the cutoff. If Order is invalid, the instruction sets
the appropriate bit in Status and uses Order = 1.
Valid = 1 to 3
Default = 1
Execution time for oversample mode.
Valid = 0 to 4194.303 seconds
Default = 0
Module update period for real time sampling
mode
Valid = 1 to 32,767ms
Default = 1
Module time stamp value for real time sampling
mode.
Valid = 0 to 32,767ms
Default = 0
