The BO object’s attributes represent the external, visible characteristics of a binary output. As a binary output, 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. This 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 N2 Controller Object.
For example, this object allows you to start or stop a fan from a supervisory controller.
For general information on Metasys system objects, see Common Object Attributes.
