To access these properties, expand Config > Drivers > KnxNetwork > KnxDevice > Comms Connections in the station Nav tree, right-click the Tunnel Connection node, and click Views > AX Property Sheet.

To configure the hidden properties you must first turn off the hidden config flag. To do so, right-click Tunnel Connection in the Nav tree, click Views > AX Slot Sheet, right-click the hidden property row(s) in the table, click Config Flags, un-check the Hidden flag, and click OK.

Property Value Description
Maximum Received Packets Que Size number (defaults to 50) Controls the size of the Tunnel Connection’s Data End Point receive queue: 2, 3 ... max.

All Group Address messages pass through this queue and end point so it is much busier than the Control End Point. Because it handles more traffic, its default queue size of 50 is larger than that of the Control End Point.

Inter Message Delay number (defaults to 15ms) Paces the out-going data requests from the driver: 15ms ... 5secs.

This can be used to reduce the rate of data requests in cases where a KNXnet/IP Interface device cannot cope with the traffic volume caused, possibly, by its implementation settings or by its operating speed. The default setting of minimum 15ms has proved successful with Siemens interface devices. Any problems arising from this being set too small would manifest as control points intermittently having a read fault: Timed out waiting for L_Data_con.

Remote Control Hpai, Ip Address read-only Reports the IP address in the format: nnn.nnn.nnn.nnn.
Remote Control Hpai, Port read-only (defaults to –1 if no connection) Reports the Port number in the format: 0, 1, ... 65535 .
