KNX gateways

Thorleifur

Hi,

What KNX gateways are you using today?

George Krietsepis

after NXB-KNX discontinuation, try CTG-KNX/IP from Comm-Tec

Donald.Peter

Sorry my bad english, but CTG-KNX/IP from Comm-Tec is not stable!
With this gateway, we have many problems with network connections.
After a network interrupt, module does not correct reconnect, or hangs in Inti-State, sometimes its need a full controller-restart.

So i write my own little module wich communicate with KNXnet/IP Tunnelling Protocol.
Its works fine, and i can when needed free extend this module.

The NetLinx coding i have translated from C# by follow source:
https://github.com/lifeemotions/knx.net/tree/master/src/KNXLib

For more information, the full protocoll specification you can download from:
https://my.knx.org/en/shop/knx-specifications

This Specifications are free, (buy for 0$), you need only create a account on https://www.knx.org/



For gateway we use the Interface IPS/S 3.1.1 from ABB.

This gateway is cheaper than Comm-Tec-Gateway and does not need 220V power!
You can also up to 5 network-connections at same time to this gatway! (NX-1200, ETS5, etc, etc, etc)

You need only ETS5 for configure the IP-Address & physical address.
ETS5 application is also available as demo by Maximum of 5 KNX devices per project.

In attachment you can find my module

Good luck

CTG-KNX/IP from Comm-Tec is no longer availible. 'Das Nachfolgemodell ist ab Mitte Mai lieferbar'
KnxNet is really, really good work, Donald.Peter!

I am using an Arcus-EDS KNX-GW-IP-2TE now, and the module written by Donald.Peter works fine with this gateway.
This module doesn't need ETS5 for configuration, it has a handy web interface.

See https://www.arcus-eds.de/system.html

Thank you Donald.Peter, you saved me weeks of coding.

Hi Donald.Peter,
is knx multicast address (224.0.23.12) supported in your module?

We have had good experiences with Weinzierl KNX BAOS modules:

The BAOS protocol for them is pretty well documented:

I used the Commtec gateway in more then 50 projects. All the gateways are still working well and stable. But it's not available anymore.
OK, now I tested the brandnew Serial and IP Gateways from the german AMX distributer. Here is the link:
https://audiopro.de/de/30362.html
the serial gateway can handle up to 1000 KNX addresses and the IP version can handle 3000 addresses. In my actual project I control 1950 addresses and everything works fine and stable.
There are some more intersting features:

• it's possible to import the complete address table, exported bei ETS software
• it's possible to manage 3000 addresses from the AMX side OR 1000 addresses from the KNX side.
• it's possible to add addresses at runtime for testing
  I'm happy with this gateway...

Hi All,
For those who used Donald.Peter's module, how do you send the actual command required to the Virtual device or string to the KNX or trigger it?
I deployed it and i can see its happy with the module opening a tunnel, but no where in the code do I see where you actually send channel to the virtual device?
Regards

Hello
You can make a Send_Command to the virtual device.
e.g.: SEND_COMMAND vdKnxMsg,"'Set:ID=1;Value=255'"
Good luck
