CODESYS EtherNet/IP Scanner/Adapter

Configurator, Protocol Stack & Diagnostics for EtherNet/IP™ fully integrated in the IEC 61131-3 Development System.

Integrated EtherNet/IP support

The real-time Ethernet system EtherNet/IP (or EtherNet Industrial Protocol or EIP) is an open standard promoted and maintained by the user organization ODVA®. EtherNet/IP is built on the application layer “Common Industrial Protocol” (CIP), extends the standard protocols TCP or UDP and makes it possible to operate standard networks and automation networks in parallel.

By means of the products integrated in CODESYS, industrial controllers (PLCs) with an available Ethernet port can be extended to provide EtherNet/IP scanner and/or adapter functionality without additional hardware.

CODESYS EtherNet/IP Scanner (originator/master)

  • Integrated configurator for the scanner and the connected adapters (targets/slaves)
  • Import of adapter EDS files
  • Integrated scanner (master) protocol stack as a CODESYS library, programmed in IEC 61131-3 code
  • Alternatively: a driver for Hilscher® EC1 or netX-based Ethernet connection with EtherNet/IP stack as well as a runtime system component for direct access to the Ethernet/IP master card
  • User library for Ethernet/IP services (messages for the remote control of connected EtherNet/IP devices)
  • Diagnostics functionality for the scanner and for connected adapters (slaves) or their I/Os in the CODESYS Development System as well as in the IEC 61131-3 application at runtime

Advantages of seamless integration

One tool with an integrated infrastructure for PLC programming and fieldbus configuration:
⇒ Simple configuration
⇒ Very few sources of error
⇒ Fast engineering 
⇒ Pure software solution with integrated scanner (master) or adapter (slave) protocol stack (standard Ethernet port is sufficient)

CODESYS EtherNet/IP Adapter (target/slave)

  • Integrated configurator for the adapter and connected EtherNet/IP modules
  • Adapter protocol stack as a CODESYS library, programmed in IEC 61131-3 code – turns a PLC into a modular EtherNet/IP device
  • Integration of a CODESYS-compatible controller in an EtherNet/IP network with any scanner
  • EDS adapter file included in the delivery scope
  • Combination with CODESYS EtherNet/IP scanner possible
  • Diagnostics functionality for the configured adapter and connected EtherNet/IP modules in the CODESYS Development System as well as in the IEC 61131-3 application at runtime

How can you obtain and implement the CODESYS EtherNet/IP support?

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

Use controllers equipped with CODESYS EtherNet/IP support. Millions of CODESYS-compatible single devices and over 1,000 different device types from more than 500 manufacturers offer you a large range of hardware for your automation projects. CODESYS Inside offers a selection of manufacturers that offer CODESYS-compatible devices. Alternatively, you can use the CODESYS Control SoftPLC Systems from the CODESYS Store. CODESYS EtherNet/IP is integrated in these systems and can be used immediately.

You are a manufacturer of programmable devices:

Implement the CODESYS EtherNet/IP support on your hardware. All you need for this implementation is the CODESYS Runtime Toolkit with EtherNet/IP support.
