[etherlab-users] Strange PDO configuration behavior

[Mirco Cremasco]

Hallo all,
I'm testing a setup with 3 modules, EL1018 (input) EL2008 (output) and a 
EL5151-0021 (encoder).
After succesfull configuring  PDO using information gathered with 
"ethercat cstruct" command (see pdo_entry struct below) ,
when I  write to digital output with
EC_WRITE_U8(domain1_pd + off_dig_out, outval);
it doesn't work!
meanwhile EL1018 end El5151 work correctly.
If I leave EL5151 unconfigured  (USE_ENC21 undefined)  EL2008 works 
properly.
What I noted is in the output of "ethercat domains --verbose" the 
digital output slave has size  14
while it should be equal to 1

Can anyone help me?
Thanks
Mirco
