7.4 BACnet Communication
7.4.1 What is BACnet Communication?
BACnet (Building Automation and Control network) is a communication network frequently
used in building automation. BACnet introduces the concept of object-oriented systems,
and defines standardized objects. By exchanging data, this function makes communication
possible between products from different companies. It also standardizes some of the
general services carried out by using these standard objects.

motors are operated, including the main motor, the interlock numbers 1,2,3,4,5 refer
to the monitors connected to Relay 1,2,3,4,5 (If interlock numbers 1,2,3,4,5 are
connected to Relay 1,2,3,4,5 at the inverter output terminal).
