ethernet port for EtherCAT communication

[XperitusT]

Which of the 3 ethernet ports can be used for EtherCAT communication

[CodeShepherd · Accepted solution]

Please see our documentation:
"ctrlX CORE Controls, Operating Manual  -->  Interfaces  -->  Interface description"
"ctrlX DRIVE Drive Systems, Project Planning Manual  -->  Mounting and installation  -->  Electrical connection  -->  Control section connection points control section"

The top one is for engeneering. The third one for another Ethernet communication.

The second one can be used for Ethercat communication. At the moment no ring topology is possible and only one master is available.

What about Star topology ,is it support connet Remote IO Module in different station and the IO mudule can not connect one by one.

Can we use the Switch Ethernet in our Ethernet Communication?

You will need a special EtherCat switches for creating other topologies. But then it doesn't matter how it does look like. EtherCat is redirecting the data stream always to a ring structure.
