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
Properties for BACnet communication and interoperability
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.
Global properties
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.
Local properties
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.
Properties for statistics and diagnostics
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.
18.2 Device info object
