7.3 About BACnet
■
Applicable Standards
• ANSI/ASHRAE135-2012
■
Profile
BACnet/IP in the MICRO/I supports the following profile.
• B-ASC
■
Objects
Information, such as input and output values handled by BACnet devices that support BACnet/IP, are managed in
units called objects. Objects are separated into a number of different types, depend on the content of the object, and
these are called object types. The object types supported by BACnet/IP in the MICRO/I are as follows.
The MICRO/I can set objects for each object type. This information can be written to and read from BACnet devices
on the same BACnet/IP network. Regardless of the object type, the maximum number of objects that can be set is
256 in total.
For details on objects, refer to “7.8 Objects” on page 3-124.
■
Properties
Properties are the detailed information and attributes of each object.
For details on the properties of each object type, refer to “7.8 Objects” on page 3-124.
■
Services
Services are interfaces used to exchange information between BACnet devices. Services are classified into the client
side that initiates services and the server side that executes services.
The Services supported by BACnet/IP in the MICRO/I are as follows.
*1 The MICRO/I initiates services for other BACnet devices.
*2 The MICRO/I executes services that are initiated from other BACnet devices.
