Mapping Tags to BACnet Objects

The BACNET driver represents the properties of BACnet objects as tags. A corresponding Plant SCADA data type is chosen for each of the supported properties (see BACnet Data Type Representation).

BACnet object properties are addressed using the following format:

<object type>.<object instance>.<property type>

Where:

• <object type> is one of the mnemonics (provided in the BACNET Supported Object Types table).

• <object instance> is the numerical object instance. Object instances may range from 0 to 4194302.

• <property type> is the property mnemonics indicated for the particular property type in the object type tables.
