Window Comparator (Wco/Wcoi) (Disconnection Detection Odc/Oidc) - Omron MX2 Series User Manual

7-8-20 Window Comparator (WCO/WCFI) (Disconnection Detection
ODc/FIDc)
The window comparator signal will be output when the analog input O/OI 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 O and OI.
The analog operation level during WCO/WCOI output can be set to a fixed value. To do so, set the
Analog Operation Level at O/OI/FE Disconnection (b070/b071). When set to no, the analog input value
will be used "as is."
The signals ODc and OIDc will be output in the same way as WCO and WCOI, respectively.
