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.

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.
