This controller can accommodate up to two KNX logic devices at the same time.

  • 1. In conjunction with the WAGO I/O System, the KNX IP Controller is used as a user-programmable application controller within KNX IP networks. The controller supports all digital, analog and specialty modules found within the 750/753 Series. The IEC 61131-3 programmable controller is capable of 10/100 Mbit/s data rates. KNX objects of any type (EIS/DPT) can be created using the programming tool. Libraries including pre-made function blocks are readily available on the WAGO Website for programming. The controller supports a maximum of 253 communication objects, as well as 254 group addresses and associations.
  • 2. Combined with the KNX/EIB/TP1 Module, the 750‐889 KNX IP Controller operates as a router on an IP backbone (ETHERNET). No IEC application is required for router functionality.

Both devices are commissioned and configured via ETS software using the WAGO product database. The software includes a plug‐in that automatically installs and opens for configuration.

The KNX IP Controller features an integrated 2‐port 10/100 Mbit/s switch, allowing a line structure to be easily created without additional network components. The maximum number of controllers that can be wired in series is 20.

An internal server is available for Web-based applications.

The controller provides 1024 KB program memory, 1024 KB data memory and 32 KB retain memory. It is capable of multitasking, has a battery-backed, real-time clock and is based on a 32-bit CPU.

The controller offers many different application protocols for control tasks (MODBUS, KNXnet/IP) or for system management and diagnostics (HTTP, BootP, DHCP, DNS, AutoIP, SNTP, FTP, SNMP and SMTP).

The number of KNX/EIB/TP1 Modules (750‐646) supported by the KNX IP Controller does not depend on the application.


The WAGO ETS3/4 plug-in is a component of the WAGO-ETS3 product databank and can be downloaded for free at
