Division into groups
The properties of the device object can be divided into groups based on
category, e.g.:
● BACnet communication and BACnet interoperability
● Global properties and system functions
● Local functions and settings
● Statistics and diagnostics
These properties ensure communication and interoperability between BACnet
devices, and are specified in the BACnet standard, e.g., Protocol version
[ProtVn] and Vendor name [VndrNam]. Individual properties such as Object
identifier [ObjId] are set up by XWP during the commissioning process on the
network side.
Individual properties of the device object are defined as global properties,
because, from the system perspective, all automation stations on one site must
have the same value. Global properties are only adjustable on the primary
server.
The device object contains local properties, which are necessary for the
parameterizing and functional scope of global objects and for functions, such
as life check, time synchronization and the replication of global objects. Local
properties also include properties for the system status of the automation
station, the time stamp for the generation of the program and the setting of the
buffer size of the alarm queue.
These properties can be reviewed in the Online Properties window in the
Network Configurator or CFC Editor in XWP.
These properties contain statistical and diagnostic information and can be
reviewed in the Online Properties window in the Network Configurator or CFC
Editor in XWP.
