Hi, I designed a 1000M media-converter for an etherCAT link equipment. I have tested it at PCs as general network devices with iperf tool and the throughput can be over 850 Mbps in full-duplex mode.
When tested with the etherCAT link devices, the link can be up and configuration is correct. But I can not make data traffic with it. The major difference between etherCAT and ethernet is that the seven bytes of preamble and the SFD, that are not critical for an ethernet link, but is a MUST option and should be kept perfectly for etherCAT. So I need to make clear if the preamble is restored totally in a media-converter and how I can test the preamble length in a media-converter.
Can you give me a exact reply?
Thanks!
