Bacnet Tags

Question 1

bacnetConn

Answer 1

bacnetConn

Marker

Marker tag for bacNet connection. See bacnetExt.

Question 2

bacnetConnRef

Answer 2

bacnetConnRef

Ref

Used on a proxy object to reference its parent bacnetConn

Question 3

bacnetCovTimeout

Answer 3

bacnetCovTimeout

Number

Applied to bacnetConn to tune the period for a COV subscription. If not configured it defaults to 5min.

Question 4

bacnetCur

Answer 4

bacnetCur

Str

Used on a bacnet proxy point to subscribe for current value. See bacnetExt.

Question 5

bacnetDevice

Answer 5

bacnetDevice

Str

Tag for current device name

Question 6

bacnetEnableOutOfService

Answer 6

bacnetEnableOutOfService

Marker

Applied to point or bacnetConn will enable getting the overridden value for points that have the BACnet OUT_OF_SERVICE (Remote Disabled) status flag.

Question 7

bacnetForcePolling

Answer 7

bacnetForcePolling

Marker

Applied to bacnetConn to force connection into polling mode, this is useful when COV updates fail or they are unreliable.

Question 8

bacnetHis

Answer 8

bacnetHis

Str

Used on a bacnet proxy point to store BACnet trend log id. See bacnetExt.

Question 9

bacnetInitInterval

Answer 9

bacnetInitInterval

Number

Applied to bacnetConn to tune the duration between driver re-initialization. When learning, the driver will cache the learned object for the period of time specified by this. If not configured it defaults to 15min. Any learn operation, after this period expires, will re-fetch the whole remote device object structure. On production setups, where points were learned and mapped, it is recommended to set this value to -1min. This will disable the sync process completely and will save a lot of traffic on the network.

Question 10

bacnetInstance

Answer 10

bacnetInstance

Number

Applied to bacnetConn it specifies what device instance number is used when the connector is in COV mode, the default instance number randomly picked between 50000 and 200000. Setting this value is required to avoid potential conflicts with an existing device on the network with the same instance number as the default used by the connector.

Question 11

bacnetLocalAddress

Answer 11

bacnetLocalAddress

Str

Applied to bacnetConn to force the connection to bind to a local address. It is useful when the local machine has multiple IP addresses or NICs attached to it, and it is required to direct the BACnet traffic to a specific interface. The format of bacnetLocalAddress looks likeIP:PORT, i.e. 10.10.10.5:47808

Question 12

bacnetUseConfirmedCov

Answer 12

bacnetUseConfirmedCov

Marker

Applied to bacnetConn to make the COV subscription mechanism to use confirmed COV messages.

Question 13

bacnetVersion

Answer 13

bacnetVersion

Str

Tag for current connection protocol version

Question 14

bacnetWrite

Answer 14

bacnetWrite

Str

Reference for bacnet object id to be written. Must also define bacnetWriteLevel. SeebacnetExt.

Question 15

bacnetWriteLevel

Answer 15

bacnetWriteLevel

Number

Number between 1 and 17 used with bacnetWriteLevel to determine which priority level of the remote system is written to.
