I’m planning to use TECO PLCs in a project and need to integrate them with KNX devices. For this, I understand I’ll need a KNX IP gateway. My question is, can I use any KNX IP gateway with TECO PLCs for this purpose, or is there a specific model I should be looking at, like the KNX IP BAOS 772?
I’m considering using ABB KNX IP gateways, but I want to ensure compatibility and avoid any issues in the setup process.
Also, if possible, could someone provide an example of how to set up communication between a TECO PLC and a KNX system through an IP gateway? I’d appreciate any guidance on this!
Thanks in advance for your help!

Our library is created for BAOS 77x KNX/IP gateways. Other gateways can use different interface so they probably will not comply with KNXIPLib in Mosaic. Of course, it is possible to use other gateway but it means to develop a new communication driver (a function block or a library). Therefore we recommend to use BAOS gateways because they are proven and we provide the support for them.
To setup the communication between Foxtrot and BAOS, you have to use uni channel on the side of Foxtrot. PLC has to be set as a TCP client, the maximum length of receiving and transmitting zone is 512 bytes. IP address and a remote port is set as an input of function block fbKnxIpBaos or fbKnxIpBaosBin. Further, you need to define variables that correspond to datapoints in the KNX network and create a list of them (KNX Object list). The function block then synchronizes all variables in the list with their counterparts on the KNX network side.
BAOS gateway has to be set using ETS programming software, just like you have to define in ETS all actions for individual events in KNX network.
