A BooleanInputPoint is a BooleanPoint with NdioBooleanInputProxyExt. It configures a UI to read contact closures as a status boolean (equipment status, binary input, BI).

The BooleanInputPoint contains only common Ndio Proxy Ext properties. Among these, note that the “Device Facets” property is blank by default.

The default operation is normal logic (closed contacts at UI is output value “true”). If needed, you can “flip” this logic in the ProxyExt by assigning a Conversion type of “Reverse Polarity.” This causes the “reversed” boolean state at the output value. Typically, you monitor normally open (N.O.) equipment contacts using normal logic.
