CODESYS® Industrial Ethernet

CODESYS supports EtherCAT®, PROFINET and EtherNet/IP™

Industrial Ethernet in CODESYS

Industrial Ethernet systems are becoming increasingly established in the field of automation technology - studies (e.g. by HMS) confirm this trend. With EtherCAT®, PROFINET and EtherNet/IP™, CODESYS supports the most important protocols with its own protocol stack and integrated configurator.

And you benefit from the integration! In addition to the general advantages of the integrated communication options, the Industrial Ethernet products in CODESYS have additional application benefits:

Pure software solution

You do not need any expensive/specific hardware, but simply use the standard Ethernet ports of your controller or IPC.

Open implementation independent of device manufacturers

Import and configure I/O modules from any manufacturer, even simultaneously in one project.

Fully integrated device scan and I/O mapping

  • Save yourself the trouble of manually entering the nodes used: Let the tool search for available nodes in the network and insert them.
  • Declare global variables for the I/O data directly in the configurator or conveniently link the I/Os with variables that have already been declared.

Standardized diagnostic interface

  • Read the diagnostics for all systems equally.
  • If required, you can also access detailed bus-specific information.

Usable library functions

  • Access acyclical and fieldbus-specific services from the PLC logic.
  • Change your I/O configuration dynamically at runtime.

Lean solution

Achieve high performance in fieldbus communication thanks to the low overhead.

CODESYS PROFINET Controller/Device

PROFINET (Process Field Network) is an open standard for an industrial Ethernet system in automation. It is managed by the user organization PI (PROFIBUS & PROFINET International as the umbrella organization of the PROFIBUS user organization PNO) and is regarded as the successor to PROFIBUS.
PROFINET uses UDP/IP and IEEE 802.3 (standard Ethernet) for acyclic services and I/O communication.

CODESYS supports PROFINET controller/device communication with integrated configurators and protocol stacks in the form of platform-independent CODESYS libraries. This allows you to configure connected I/O modules with inputs/outputs, alarms, diagnostics and parameters. Drivers for standard network cards for communicating I/O data and acyclic services are included in the scope of delivery.

Range of functions / features

  • Import of PROFINET GSDML configuration files (PROFINET XML format)
  • Configuration of PROFINET parameters of controllers, I/O modules, I/O devices and their inputs/outputs, alarms, diagnostics and parameters
  • Convenient variable mapping with division into bit channels
  • Calling up PROFINET services directly from the configurator, such as reading out I&M data, setting the station name and IP configuration, and "Reset to Factory"
  • Topology configurator (for device replacement, IRT planning)
  • Media Redundancy (MRP) Configurator
  • Combination of CODESYS PROFINET Controller and CODESYS PROFINET Device possible
  • Integration of a CODESYS-compatible controller as a PROFINET device in a PROFINET network with any controller (example GSDML file included)
  • Fast startup

  • Redundancy support S2
  • Extensive library API, e.g. acyclic read/write
  • Alarms
  • Dynamic connection setup
  • Reconfigure
  • Support for IO-Link gateways
  • No artificial limitation of the number of IO data
  • Parallel operation with other communication services (e.g. web server, other fieldbuses) possible on one Ethernet port
  • Can be used on Windows, Linux, VxWorks-based systems
  • Alternative use of CIX-based fieldbus cards with integrated stack possible
     

CODESYS EtherNet/IP Scanner/Adapter

As an open standard, the real-time Ethernet system EtherNet/IP (or EtherNet Industrial Protocol or EIP) is managed by the user organization ODVA®. EtherNet/IP communicates via the Common Industrial Protocol (CIP) as an application layer, extends the standard TCP and UDP protocols, and enables parallel operation between standard and automation networks.

With the products integrated in CODESYS, industrial controllers with a free Ethernet port can be extended with EtherNet/IP without additional hardware - as a scanner and/or adapter.

Range of functions / features

  • Integrated configurator for the scanner and connected adapters (targets) as well as connected EtherNet/IP modules
