understanding the Anatomy of a Counting- Driven BAS

A Building Automation Systemem typically controllers superiory controllers, field- level controllers, sensors, actuators, and a user interface for monitoring and control. Counters serve as specialized sensors that acculate disculate events or continuous values over time. The integration process involves connecting these counting devices to the BAS network so that their data can be polled, stold, analyzed, and for control logic.
