Below is the answer I received from Yaskawa, the developers are in Japan. This is the only time I have seen a device return 0's for Vendor and Product code. They claim everything is there and it can't be change. <TT>The device is recognized by TwinCat so the data must be in the device. </TT><BR>
<BR>
<TT>Any ideas of what I can look at to find the cause of the SII: Error on last SII command and EtherCAT ERROR: Failed to read SII size of slave 0 errors?</TT><BR>
<TT> </TT><BR>

<FONT SIZE="2">Hi Henry,</FONT><BR>
<BR>
<FONT SIZE="2">We got an answer from the developers as below:</FONT><BR>
<BR>
<FONT SIZE="2"><FONT COLOR="#0000ff">Sigma-5 amplifier with EtherCat card is categorized as "Variable Process Data,Object Dictionary " that specified on the chart on "<A HREF="http://www.etherlab.org/en/ethercat/faq.php">http://www.etherlab.org/en/ethercat/faq.php</A>" and all of items (including optional items) are defined on our EtherCat card. These items on the EEPROM are permanent (fixed) information and are not editable (no changeability, not overwritable , not deletable). These are same information as ESI.. We would like to recommend DeltaTau using conformance test tool for their investigation.</FONT></FONT><BR>
<BR>
<FONT SIZE="2">Let me know if you have other questions you'd like us to consider.</FONT><BR>

Maybe the SII contents you wrote are too large for the EEPROM and you
overwrote the beginning again? Try to get to know the size of the
EEPROM.
