| Property | Value | Description |
|---|---|---|
| Node Max Bvlc Length | number (defaults to 65535) | Specifies the maximum BVLC (BACnet Virtual Link Control) message size that can be received and processed by the node in bytes. |
| Node Max Npdu Length | number (defaults to 61327) | Specifies the maximum NPDU (Network Protocol Data Unit message size that can be handled by the node's network entity in bytes.
This value must be less than the Node Max Bvlc Length. The difference determines the maximum size of BVLC destination and data options.

| Minimum Reconnect Time | hours minutes seconds (defaults to two seconds) | Defines the shortest amount of time to wait following a failure before attempting the connection again.
A second consecutive primary connection failure waits an amount of time that is double the minimum. A third failure waits
four times the minimum, a fourth eight times the minimum, etc. up to the Once it reaches the maximum, which defaults to 10 minutes, the connection attempts to reconnect every maximum amount of time forever. |
| Maximum Reconnect Time | hours minutes seconds (defaults to two minutes) | Defines the longest amount of time to wait following a connection failure before attempting to connect again. |
| Connect Wait Timeout | hours minutes seconds (defaults to ten seconds) | Defines how long a connection waits for an initial response message before concluding that the attempt failed. |
| Disconnect Wait Timeout | hours minutes seconds (defaults to ten seconds) | Defines how long a node waits for a response message while disconnecting. |
| Web Socket Wait Timeout | hours minutes seconds (defaults to ten seconds) | Defines how long a connection waits without success to establish a web socket connection before concluding that the attempt failed. |
| Initiating Heartbeat Timeout | hours minutes seconds (defaults to five minutes) | Defines how long an initiating hub or direct connection waits without receiving any messages before sending a heartbeat request message. If no messages are received after another timeout period, the connection will be disconnected. |
| Accepting Heartbeat Timeout | hours minutes seconds (defaults to eight minutes) | Similar to Initiating Heartbeat Timeout except that it applies to accepting hub and direct connections. The value of this timeout is typically longer than the Initiating Heartbeat Timeout so that the initiating connections usually send heartbeat request messages.
