There are no mailbox sync manager... Doesn't the slave support CoE? How
is the oversampling factor configured then?

Could you please try to exchange data from all sync managers in any
combination to see how the working counter changes? I mean first
register only a PDO entry from SM0 then, one from SM0 and one from SM1,
and so on. There are 8 possible combinations. In how far does the
working counter change?

Best regards,
