Seamlessly integrated communication protocols

The core task of CODESYS is the simple programming of logic controllers according to IEC-61131-3. In addition, the automation software offers extensive support of communication protocols for data exchange with other systems in the automation landscape.

All controllers communicate in real time with connected field devices, such as sensors and actuators. For this purpose, all important fieldbus and Industrial Ethernet systems are implemented in CODESYS. These products can be found in the category CODESYS Fieldbus.

In a connected Industry 4.0 architecture, modern controllers also exchange their information with other systems. These can be other controllers, but also any other intelligent devices in the controller network, connected MES or ERP systems, and private or public clouds. CODESYS makes communication simple: with proprietary and standard protocols that are seamlessly integrated into the platform:

  • As components in the CODESYS Control runtime system, which means they are firmly integrated in the control system
  • As components of the CODESYS Development System or as extension APIs
  • As reloadable libraries that are compiled along with the application code of the logic controller for the respective target device and executed there.

Your advantages

  • You only use tested and approved products you can rely on. Sample projects make it easier for you to use communication.
  • You can access the physical interfaces available in the device directly from the PLC application, e.g. Ethernet, serial interfaces, or controller I/Os.
  • You can exchange data directly with the most important communication protocols - via OPC UA as well as MQTT or http/https.
  • You integrate the protocols implemented as a library into your application. Such protocols, which you do not use, do not occupy any resources on the controller.
  • Using the possibilities of a modern programming tool (IDE), you can create and use your own protocols directly in CODESYS - without any external software environment. You can even offer the libraries developed in this way to other users via the CODESYS Store.

How can you obtain CODESYS Communication?

You are a system integrator or a user in the machine/plant construction sector or the like: Use controllers that are already equipped with integrated CODESYS communication protocols. The CODESYS Device Directory provides you with a wide range of options for device selection. Alternatively, you can use the CODESYS Control SoftPLC systems from the CODESYS Store, which already implement a number of protocols. In the CODESYS Store, you will find numerous libraries for extending the pool of integrated communication protocols.

You are a manufacturer of programmable devices: Implement in your devices the required communication components of the CODESYS Runtime Toolkit as well as the possibility to license libraries per device.
