3-6-15 Window Comparator, Analog disconnection
The window comparator function outputs signals when the values of analog
inputs O and OI are within the maximum and minimum limits specified for the
window comparator. You can monitor analog inputs with reference to arbitrary
levels (to find input terminal disconnection and other errors).
You can specify a hysteresis width for the maximum-limit and minimum-limit
levels of the window comparator. You can also specify limit levels and a hys-
teresis width individually for analog inputs O and OI.
You can fix the analog input data to be applied to an arbitrary value when
WCO or WCOI is output. For this purpose, specify a desired value as the
operation level at O/OI disconnection (b070/b071/b072). When "no" is speci-
fied, the analog input data is reflected as input.
Output values of Odc and OIDc are the same as those of WCO and WCOI,
respectively.
