[etherlab-users] "PDO entry 0x6000:02 does not byte-align in config 0:7. PDO entry registration failed! "

[Fabian Herb]

Hi Christian!

Instead of passing the structs to ecrt_slave_config_pdos(), you can use 
ecrt_slave_config_reg_pdo_entry() to register each PDO individually. This 
function has an optional parameter to get the bit position. With this provided 
it won't complain about byte alignment.

It also seems to work to only register the first PDO entry, and you get access 
to the other entries that share the same byte. I think this is the way it is 
done in the digital IO examples.

Best regards,
Fabian Herb
