Knx Device/Comms Connections/Tunnel Conn

Tunnel Connection.
Property Value Description
Maximum Received Packets Que Size 2, 3 ... max Defaults to 50 Maximum Received Packets Que Size.

Controls the size of the Tunnel Connection’s Data End Point receive queue. All Group Address messages pass through this queue and End Point so it is much busier than the Control End Point (see KNXnet/IP Tunnel Connection — Control). Because it handles more traffic, its default queue size of 50 is larger than that of the Control End Point.

Inter Message Delay 15ms ... 5secs Defaults to 15ms Inter Message Delay.

This setting exists to ‘pace’ the out-going data requests from the driver. 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 fault condition.
