7-8-20 Window Comparator (WCFV/WCFI) (Disconnection Detection
FVDc/FIDc)
The window comparator signal will be output when the analog input FV/FI value is between the upper
and lower limit settings. It is useful for monitoring the analog input at a level to detect disconnection or
other faults.
The hysteresis width can be set for the upper and lower limit level settings for the window comparator
function.
In addition to the hysteresis width, the upper and lower limit levels can be set individually for each of the
analog input signals FV and FI.
The analog operation level during WCFV/WCFI output can be set to a fixed value. To do so, set the
Analog Operation Level at FV/FI/FE Disconnection (b070/b071). When set to no, the analog input value
will be used "as is."
The signals FVDc and FIDc will be output in the same way as WCFV and WCFI, respectively.
