The powerful ILC 2050 BI controller is specially designed for automation tasks in buildings. The extension with a large number of I/O components from the Inline system ensures the easy setup of a modular automation station for practically all tasks in the building infrastructure environment. In particular, these include controlling and monitoring the building infrastructure, and energy management. The corresponding software makes the automated building IoT capable without effort.


Your advantages

  • Easy programming with the graphical build-up of control functions from a large library of ready-to-use blocks
  • Support for all of the main communication protocols in the field of building infrastructure automation technology
  • Possibility of live engineering without interrupting ongoing operation
  • Safeguard cost-efficient operation with remote access for programming, monitoring, software updates, and functional extensions
  • Secure operation with consistent encryption in the network, digital signaling, and authentication based on various user roles

Integration of subsections – open, efficient, limitless

Easy integration of different subsections

The controller is based on the powerful Niagara framework. The key advantage here is the unified connection of various bus systems and protocols on the field level through data standardization. For this, there are numerous communication drivers for classic systems such as Modbus/RTU, BACnet MS/TP, and LON TP/FT10, as well as support for IP-based protocols such as Modbus/TCP, BACnet/IP, and KNXnet/IP. Naturally, building-specific protocols such as DALI, M-Bus, SMI, and others are also supported. The integrated network function ensures that all data points are very easily available anywhere within an overall system comprised of several controllers. External data exchange is possible using IoT protocols such as MQTT and OPC UA, among other methods.

Flexible license model


Flexible licensing – tailor-made solution

A license is required for each controller. The basic version includes 100 data points and the support of numerous protocols. With extended licenses, the number of data points can be increased to up to 10,000. Driver licenses are available to extend the functional scope of the controller to include additional protocols. We recommend maintenance licenses to ensure that you benefit from software updates and new functions. These licenses are available with a runtime of one, three, or five years. A new release is issued twice per year.

On request, we will be happy to advise you on selecting the license suitable for your project.

Supervisor and workbench

Control cabinets and industrial PC with visualization  

Easy and efficient configuration of stations


A supervisor is a server-based automation station for superordinate tasks in a network, comprised of several type ILC 2050 BI controllers. With this, the central logging and aggregation of data points and a central alarm management and scheduling system are possible.

The supervisor realizes complex visualizations and simplifies integration into superordinate systems. It takes over central administration tasks such as rolling out software updates, as well as user and certificate management in the network. Moreover, it can independently implement control tasks with data points that are made available via TCP/IP-based protocols.




The workbench is the uniform software interface for the programming and administration of all controllers and supervisor stations in an overall network.

In the workbench, the control functions are developed in a graphic editor through linking and configuring function blocks. Changes are introduced without interrupting ongoing operation. The values of all data points are displayed in real time. If the data is temporarily overwritten, it is possible to view the histories. The use of self-created templates for more complex tasks facilitates effective workflows, even in large projects.
