BACnet Connection Properties

localInterface (string)

Local interface used to receive data

Default: "eth0"

Examples: "lo", "eth0"

localPort (integer)

Local port used to receive data

Default: 47808

Example: 47808

deviceInstance (integer, required)

Integer number describing the device instance

Example: 27335

deviceAddress (string, required)

Device address as UDP network address in the form ip-address:port-number. The port can be skipped if only one device is available under the given IP address

Example: "192.168.2.114:40426"

connectionStrategy (object)

If a connection attempt fails, retries will be performed with increasing delay (waiting time) in between. The following parameters control how these delays behave.

Properties of the connectionStrategy object:

initialDelay (integer)

Delay (waiting time) of the first connection retry (in milliseconds). For subsequent retries, the delay will be increased according to the parameter incrementFactor which has a default value of 2.

Default: 1000

Additional restrictions:

• Minimum: 1000

maxDelay (integer)

Maximum delay (waiting time) to wait until the next retry (in milliseconds). The delay (waiting time) for any subsequent connection retry will not be larger than this value. Must be strictly greater than initialDelay.

Default: 30000

incrementFactor (integer)

The factor used to increment initialDelay up to maxDelay. For example if initialDelay is set to 1000 and maxDelay to 5000 the values for the delay would be 1000, 2000, 4000, 5000.

Default: 2

Additional restrictions:

• Minimum: 2
