[etherlab-users] How to expose the PDO mappings?

[Oliver.Haala at semikron.com]

Hello,

Using "ethercat pdos" causes the same problem on my system: the result is nothing.
(Same problem with "ethercat cstruct") Beckhoff-Support told me, that my SII data 
is complete. 

SII Area:
08 00 02 00 00 00 00 00 00 00 00 00 00 00 b7 00
02 00 00 00 22 2c 60 04 00 00 10 00 00 00 00 00
00 00 00 00 00 00 00 00 00 10 14 02 00 18 14 02
00 1c 88 00 00 1e 88 00 0d 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 01 00 01 00

The "Debug-Version" of my bus consists of:
BK1120 - KL2012 - KL3001 - KL9010
What else could cause that problem?

BTW: Are the commandline-tools reg_read/reg_write working in anyway to parametrize 
the intelligent KL terminals? Or rather, How to access the non-slave-bus-terminals memory?

Regards
Oliver

The reason is, that the SII data are incomplete:
