Lenze Engineering Online access with EtherCAT EoE to Endpoint function (TwinCAT)

The Beckhoff Controller system supports two communication interfaces for 3th party Engineering Tools

1.           Beckhoff ADS communication

• This is a Beckhoff specific proprietary communication protocol.
• Beckhoff uses it for their controller system and the TwinCAT software.
• The Lenze "Easy Starter" supports this protocol with the communication path setting   "Ethernet - EtherCAT via Beckhoff controller"

2.           EtherCAT " EoE to Endpoint" communication

• This is a standardized EtherCAT communication protocol, tunnelling Ethernet communication via the EtherCAT mailbox to the field devices.
•  Different controls supplier (Beckhoff, Bachmann, … ) are supporting this in their control equipment to allow various 3^rd party supplier to access their components on the EtherCAT with their own PC-Tools.
    In practice the controls supplier has implemented an ip routing from the physical Ethernet port to the virtual Ethernet port of the EtherCAT master in their controller. 
  
•  The Lenze "Easy Starter" supports this tunnelling with the communication path setting   "Ethernet"

This articles describes the option 2 in practice with a Beckoff controller.
