CODESYS in Building Automation

IEC 61131-3 development software for efficient building and infrastructure automation.

CODESYS is used for the automation of commercial buildings and private homes, for example for intelligent lighting control, shading or air conditioning for individual rooms or complete floors or for the management of entire building complexes.

Why is that so?

  • CODESYS supports heterogeneous system architectures consisting of compact controllers for example to monitor individual rooms or of panel controllers to control different rooms with a single device, aggregate control systems and other automated systems used in buildings.
  • Different devices from different manufacturers can be used to automate buildings with CODESYS. System integrators can choose their preferred devices independently of the manufacturer. With established industrial standards such as OPC UA, or web technologies like MQTT or REST API, external system architectures can be connected flexibly and reliably to the CODESYS system.
  • Thanks to integrated options for network and fieldbus configuration, flexible network topologies can be developed by using BACnet®, KNX®, Modbus, CANopen®, and PROFIBUS. Industrial Ethernet protocols such as EtherCAT® or PROFINET can also be used.
  • The CODESYS Web Visualization makes room data readily accessible to facility managers. Using Data Sources, they can access or collect the required room data for monitoring purposes. Likewise, a service technician can display and modify the status data of primary systems, aggregate controllers, floor or application controllers via Internet access without being on site himself.
  • CODESYS provides the necessary possibilities for compliance with IT security in order to protect the systems against unauthorized access or data manipulation. The same established technologies as are relied upon today, e.g. in online banking are used.
