BACnet System

7. BACnet System

7.1. General Description

BACnet is a solid standard with many detailed concepts, but for this manual purposes, we will focus on the two
most fundamental concepts:
• BACnet client, which is the device that sends service requests to the server.
• BACnet server, which is the device that performs the requested service and reports the result back to the
client.
BACnet server devices are represented in the form of devices holding objects. Usually, every physical device
corresponds to a logical one. The objects can be of different types depending on the data and functionality they
represent: Analog input, Analog output, Digital input, etc.
NOTE
• Output objects are meant to be written from the BACnet network to the device.
• Input objects are meant to offer status information on the BACnet device.
• Value objects are bidirectional.
Every object has different properties. The most meaningful one is the Present_Value property, which indicates
the real value of the object. Also, the gateway uses this property to read and write values. Every object of the
same type in a device is identified with its associated object instance.
NOTE
Refer to the Protocol Implementation Conformance Statement (PICS) document
information.
NOTE
This model supports BACnet descriptions, this is configurable through the Intesis MAPS configuration
tool.
