you mean the ecdb.h? This is a just convenience header for slaves's
vendor IDs and product codes...

If the slave has fixed PDO's, you can extract the PDO information from
the slave's EEPROM. If it has variable-size PDO's (like in this case)
you'll have to know the PDO sizes. Then you can register a PDO range
(ecrt_domain_register_pdo_range()) and exchange the complete process
Although we have no experiences with Beckhoff's CANopen slaves, we have
a BK1120 KBUS coupler running.
