Communication via Standard Ethernet

How does CODESYS communicate via Ethernet? How can I send and receive data from a CODESYS-compatible PLC via TCP or UDP? How can I realize data exchange from the PLC application?

Today, almost every industrial controller has an Ethernet connection. It is usually used for programming the device and exchanging data with other systems. The physical interface can be used with different protocols.

For communication with I/O systems, motors, or intelligent units of the control architecture, Industrial Ethernet protocols are commonly used. For more information, please click here.

Ethernet with TCP/IP is used in CODESYS not only for programming, but also for communication with CODESYS Visualizations, e.g. with CODESYS HMI or CODESYS WebVisu.

Users can also exchange dedicated data from the IEC-61131-3 logic application. The free “network.library” library (CODESYS Base Libraries add-on), which is included in the CODESYS Development System, provides important basic services for this. This library provides a convenient interface for socket communication from the controller to other systems via TCP/IP and UDP.

How can you use Ethernet in CODESYS?

You are a system integrator or a user in the machine/plant construction sector or the like:

  • Program CODESYS-compatible controllers or standard device platforms that are equipped with integrated Ethernet interfaces.
  • Connect additional visualization devices, e.g. operating panels equipped with CODESYS HMI or HTML5 browsers that display the CODESYS WebVisu.
  • Send and receive controller data from the IEC 61131-3 logic application via the available function blocks of the network.library.

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.
