I did that, but I still couldn't find out how to "Add the slave to a
new project". I did "File/New", then (guessing) right-clicked on
"I/O devices" in the tree and selected "Append Device". But in the
dialog that appeared I didn't find the Baumueller devices (under
"EtherCAT" where I expected it, or anywhere else).

Anyway, Ronaldo has converted the XML file for me (thanks!).
However, even in this file the two relevant bits (enable_pdo_assign,
enable_pdo_configuration) were not set, so apparently this
information was not given in the XML file either. (Apart from that,
the file contained only apparently trivial differences from the SII
file I downloaded, such as slightly different strings.)

So that I can complain to Baumueller properly, as suggested on the
web page, I'd have to know whether this information is/should be
actually contained in the XML file and what I should look for.

I agree, such a tool would be nice. I found some relevant parts of
the SII format in the Etherlab sources (master/fsm_slave_scan.c),
but I'm not familiar with both this and the XML format to write such
a tool.

I can't find it either. Maybe it's available only for ETG members.
