Pool’nX KNX-IP settings: ETS tunneling, routing and address tables

The local configuration site of the Pool’nX sets its KNX-IP part: individual addresses of the tunneling connections, multicast routing, acknowledgement tables and routing tables, which you can fill from an ETS export.

Intended for the KNX integrator who connects ETS or another KNXnet/IP client to the gateway, or who integrates it into a KNX IP network. To open the site, follow signing in to the local configuration site.

Before you start

• You are signed in to the local configuration site of the gateway.
• Plan free individual addresses on the KNX line and, for routing, the multicast address used by the other routers.

Set tunneling and routing

1. In the menu, open KNX-IP. The KNX-IP Settings page shows the Connection Settings card.
2. Port shows the KNXnet/IP port of the gateway, 3671, read-only.
3. In Individual address, fill in the individual addresses of the tunneling connections, for example 1.1.250 (example). Add a row with + Add individual address, up to 16 addresses; remove one with Remove.
4. To connect the gateway to other KNX IP routers, tick Routing and fill in the Multicast address. The standard KNX multicast address is 224.0.23.12.
5. Click Save. KNX-IP settings saved confirms the save.

Each simultaneous tunneling connection, from ETS or from a visualization, uses one individual address. Choose free addresses on the KNX line.

The Bus Voltage Monitoring card on the same page is set with its Interval (minutes) and its KNX Address, then its own Save button.

Connect ETS in tunneling mode

1. In ETS, add a KNXnet/IP connection to the local IP address of the gateway, port 3671.
2. Choose tunneling mode and test the connection.
3. Open the ETS group monitor to check that the bus telegrams arrive.

ETS reaches the gateway at its local IP address: the computer running ETS must be able to reach this address on the network.

Fill in the acknowledgement tables

1. Open Adresses Tables, then the Acknowledge tables: section.
2. In Group addresses ACK and Physical addresses ACK, add with + Add row the addresses for which the gateway acknowledges telegrams on the KNX bus. Each table accepts up to 20 rows.
3. Click Save. Tables saved successfully confirms the save.

A row accepts an address or a pattern:

Pattern	Group addresses	Physical addresses
A single address	1/2/3	1.2.3
Wildcard on one level	*/2/4	*.2.4
Ranges	1/2-7/5-9	1.2-7.5-9

Filter routing between IP and KNX

The routing tables only appear if Routing is ticked on the KNX-IP page.

1. On the Address Tables page, open the Group address forward section.
2. Fill in Group Address forward IP to KNX and Group Address forward KNX to IP. Tick Broadcast (0/0/0) to also forward address 0/0/0 in the direction concerned.
3. In the Physical address forward section, fill in Physical Address forward IP to KNX and Physical Address forward KNX to IP in the same way. The Physical address forward — Default box sets the default forwarding of physical addresses.
4. Click Save.

Import the ETS filter table

1. In ETS 5 or 6, export the filter table in HTML format.
2. On the Address Tables page, open Import ETS file and drop the .html file.
3. The Replace routing tables? window shows This will replace the current GAfwdIP and GAfwdKNX routing tables with the addresses from the imported file. Click Replace.
4. The message gives the number of address groups imported into the routing tables. Both group tables, from IP to the bus and from the bus to IP, receive the same addresses.
5. Click Save to save the imported tables.

Check the result

• Reload KNX-IP and Address Tables: the addresses entered are kept.
• The ETS tunneling connection succeeds and its group monitor shows the telegrams.
• With routing, send a value from the IP network to a filtered address and check that it is received on the bus in the group monitor of the gateway.

Troubleshooting

Message or symptom	Cause and action
Tunneling connection refused	All the individual addresses are in use. Add an address in Individual address, then save.
Group address forward section missing from Address Tables	Routing is not ticked. Tick it on the KNX-IP page and save.
No group addresses found in this file	The file is not an HTML export of an ETS filter table. Export it again from ETS.
+ Add row button missing	The table already has 20 rows. Group addresses together with a pattern.
Failed to save or Failed to save tables	The save did not succeed. Reload the page and save again.
