Direct Initiating Connection (bacnet-DirectInitiatingConnection)

This component configures a direct initiating connection between two BACnet/SC nodes.

Figure 52. Direct Initiating Connection properties

To access these properties, expand a secure connect port, expand Link > Node Switch > Connections and double-click the InitiatingConnection1 component.

Property	Value	Description
State	read-only	Indicates the current high-level state of the connection.
Sub State	read-only	Indicates the current detailed state of the connection.
Peer Uri Address	text	Constitutes the authority component (host and port) of the connection’s web socket..
Peer Uri Path	text	Specifies the path component of the connection’s web socket URI.
Peer Uri Query	text	Indicates the query component of the connection’s web socket URI.
Peer Address	Internet address	Specifies the Internet address of the peer node to which this connection is linked.
Peer Vmac	number	Specifies the VMAC address of the peer node to which this connection is linked.
Peer Uuid	number	Constitutes the device UUID of the peer node to which this connection is linked.
Peer Max Bvlc Length	read-only	Reports the maximum length of the BVLC (BACnet Virtual Link Control) message that can be received and processed by the ntarget node in bytes as reported in the Connect-Accept message..
Peer Max Npdu Length	read-only	Reports the maximum length of the NPDU (Network Protocol Data Unit) message that can be handled by the target node’s network entity in bytes as reported in the Connect-Accept message.
Peer Info	additional properties	For property descriptions, refer to Peer Info.
Last Connect	read-only	Indicates the last time this connection successfully connected.
Last Disconnect	read-only	Indicates the last time this connection was disconnected.
Last Failure To Connect	read-only	Indicates the last time this connection failed to connect.
Error	additional properties	Specifies the error class and code of the most recent error for the connection.
Error Details	read-only	Specifies additional details about the most recent error for the connection.

Actions

Connect attempts to make a connection to the peer node.
Disconnect stops the connection with the peer node.
Change Peer Vmac sets the Peer Vmac property. This is required for sending Address-Resolution and Advertisement-Solicitation messages if the connection has not yet been established.
Send Address Resolution sends an Address-Resolution message to the peer node based on the Peer Vmac property value.
Send Advertisement Solicitation sends an Advertisement-Solicitation message to the peer node based on the Peer Vmac property value.

Peer Info

These properties provide information about the peer-to-per connection.

Figure 53. Peer Info properties

To access these properties, expand BacnetNetwork > Bacnet Comm > Network, expand a secure connect port or hub port, expand Link > Node Switch > Connections, double-click an initiating connection and expand Peer Info.

Property	Value	Description
Hub Connector Status	read-only	Reports the condition of the target node’s connection.
Accepts Direct Connections	read-only	Indicates if the target node is capable of accepting direct connections.
Direct Uris	read-only	Identifies the possible URIs that the initiating connection can use to make a direct connection to the target node. The values in this property are received in the Address-Resolution-Ack message.
Max Bvlc Length	read-only	Reports the maximum length of the BVLC (BACnet Virtual Link Control) message that can be received and processed by the target node in bytes as reported by in the Advertisement message.
Max Npdu Length	read-only	Reports the maximum length of the NPDU (Network Protocol Data Unit) message that can be handled by the node’s network entity of the target node in bytes as reported in the Advertisement message.
Address Resolution Status	read-only	Reports the status of the last Address-Resolution message sent to the target node.
Address Resolution Timeout	hours minutes seconds (defaults to 10 seconds)	Configures how long to wait for an Address-Resolution-ACK message after sending an Address-Resolution message to the target node before timing out.
Advertisement Solicitation Status	read-only	Reports the status of the last Advertisement-Solicitation message sent to the target node.
Advertisement Solicitation Timeout	hours minutes seconds (defaults to 10 seconds)	Configures how long to wait for an Advertisement message after sending an Advertisement-Solicitation message to the target node before timing out.
