The BI object’s attributes represent the external, visible characteristics of a binary input. As a binary input, this object can be in either an Active or Inactive state. The Polarity attribute allows for normally open relays that are Active when energized and normally closed relays that are Inactive when energized.
The Binary Input object integrates N1, N2, and BACnet controllers into supervisory controllers, resulting in:
-
a consistent interface to point objects for all controller types, so they appear as a homogenous set to the user interface
-
flexibility in point mapping
-
support for all Metasys controllers. See the N2 Controller Object section.
For example, this object allows you to map a fan status into a supervisory controller.
For general information on Metasys system objects, see Common Object Attributes.
