    Good question. Is this gateway doing EtherCAT Master to Profibus slave or Profibus Master to EtherCAT slave?

    Thanks,

    With AM335x, it is possible to do PROFIBUS slave to EtherCAT master gateway.

    But it is not feasible to do EtherCAT slave to PROFIBUS master.

    The reason is the both PRUs are required for EtherCAT slave, PROFIBUS slave or PROFIBUS master implementation. When PROFIBUS slave is used, then there is another Ethernet switch available in the AM335x and one of the ports on the switch can be used as EtherCAT master.

    You may want to explore connecting an external chip to AM335x to get the second interface as it may still be a better solution.

    Thanks.
