Item no. 750-849

Controller KNX IP; light gray


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. It permits data transmission rates of 10/100 Mbit/s and is programmable in accordance with IEC 61131-3. 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 254 associations. Supported DPTs: All (per KNX standard 03_07_02 Datapoint Types V1.0).
  • 2. Combined with the KNX/EIB/TP1 Module, the 750‐849 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 in ETS3/4 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 512 KB program memory, 256 KB data memory and 24 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.
