Configurator, Protocol Stack and Diagnostics for Sercos® III fully integrated in the IEC 61131-3 Development System

Integrated Sercos III master support

Sercos III is the third generation of the Sercos interface based on standard Ethernet.  The system, the international standardization of which is pending, is mainly used to access automation systems with motion control functionality.

Sercos International e.V. is the user organization responsible for the standardization and marketing of the Sercos interface.

The Sercos master integration in the IEC 61131-3 Development System CODESYS comprises

  • an integrated configurator for the master and the connected slaves
  • a portable protocol stack in form of a CODESYS library
  • a driver for the Automata® Sercos master card
  • a runtime system component (CoSeMa) for direct access to the Sercos master card
  • diagnostics functionality in the Development System and possibility to monitor the process through the IEC 61131-3 application

Advantages of the seamless Integration

One tool with an integrated infrastructure for PLC programming and fieldbus configuration:
⇒ Simple configuration
⇒ Very few sources of error
⇒ Fast engineering
