The BACnet interface provides the opportunity to read and write BACnet Objects and their BACnet Properties.
The structure of the BACnet object definition file is as follows:
' BACnet object configuration file
' DeviceId;ObjectId;ObjectType;ObjectName;WritePriority;PollingInterval;Persistent;Historical;Synchronize;COVType
257653;0;Binary Input;BINARY_INPUT_0;15;5000;F;F;F
257653;0;Binary Output;BINARY_OUTPUT_0;15;5000;F;T;F

2098178;1;Multi-State Value;B'17;15;5000;F;F;F
Each line – except comment lines that start with ' – defines a single BACnet object.
! The BACnet object definitions within this file can automatically be set by using the BACnetExplorer. Therefore, editing it manually is not necessary in general.
| 1 | DeviceId | The BACnet Device ID of the device which holds the BACnet Object. This name must match the device ID used in the BACnet device configuration. | |
| 2 | ObjectId | This parameter refers to the BACnet Object ID of the defined object. | |
| 3 | ObjectType | This attribute defines the BACnet Object type. | |
| 4 | ObjectName | This identifier specifies the BACnet Object Name of the BACnet Object. | |
| 5 | WritePriority | Here, the default write priority de- fined in the BACnet configuration file can be overwritten for each individual object. If not specified, the default write priority is used. As an alternative, a list of write priorities (separated by ",") can be specified, too. For each defined write priority, the server creates two additional server item – one for writing the datapoint value with the specified priority and one for resetting the priority again. Using this mechanism, multiple BACnet priorities can be used at the same time. | |
| 6 | PollingInterval | If the object does not support Change of Value (COV) subscription, this parameter defines the interval (in ms) which is used to poll the object's present value. "'0"' deactivates polling for this object. | |
| 7 | Persistent | This parameter specifies whether the value of the datapoint is persistent (restored from the database after server start up ) or not. | |
| 8 | Historical | This parameter specifies whether historical values of the datapoint are stored within the database or not. | |
| 9 | Synchronize | If this parameter is set to "T", the value is synchronized between the main and backup server (if present). This will work only if synchronize is enabled in the NMESH configuration of the NETx BMS Core Server. | |
| 10 | COV Type | This parameter specified the type of COV subscription that shall be used for the given object. "'Unconfirmed"' uses unconfirmed COV subscription, "'Confirmed"' uses confirmed COV subscription, and "'Disabled"' deactivates COV subscription at all. The default value (emtpy value) is "'Unconfirmed"'. | |
| 11 | Proprietary properties | This column is used to specify the properties of proprietary object types that shall be shown as Server Items. It is a comma separated list E.g. 6704,6708 | |
| 12 | Proprietary data types | ||
| 13 | Proprietary access |
