This Driver can search for BACnet devices in the local network. This is performed by broadcasting the Who-Is BACnet service and receiving the I-Am BACnet service. To do so, click Auto-Detect on the BACnet tab. If the list of devices is empty, this feature can also be started by expanding the Network Browser node in Tag Browser.

The Auto-Detect Devices Range property defines the search ranges to use by this Driver. This property must be filled with a list of ranges of instances of devices to search for. The syntax for each range is the following:

"<low device #>-<high device #>"

 

Or:

"<single device #>"

 

Where:

•<low device #>: Instance number of the beginning of the range, included, which must be less than <high device #>

•<high device #>: Instance number of the end of the range, included, which must be greater than <low device #>

•<single device #>: Instance number of the range with a single value

 

These ranges must be listed in ascending order, without intersections, and separated by commas. Examples:

•"0-4194302": Searches for devices whose instance number ranges from 0 (zero) to 4194302. This is the property's default value, which corresponds to the entire range

•"0-100, 200-300": Searches for devices whose instance number ranges from 0 (zero) to 100, or from 200 to 300

•"0-100, 150, 200-300": Searches for devices whose instance number ranges from 0 (zero) to 100, is equal to 150, or from 200 to 300

 

Each defined range corresponds to sending a Who-Is message and receiving I-Am responses. Therefore, the more defined ranges, the longer the auto-detection process takes.
