Two kinds of configuration are possible:

  • Configuration by tool
  • By XML file generated by the “EtherCAT Configurator” available from the ETG or by TwinCAT IO tool available from Beckhoff. In this case, the name of the configuration file is ethercat.xml


Firmware supports common diagnostic in the dual-port-memory of the loadable firmware.
