If you can see PDOs in the "ethercat pdos" view, then that mapping method must be supported. Otherwise either someone has misinterpreted something or the device is not actually EtherCAT conformant and you should use something else instead. (Slave vendors are required to sell only conformant devices.) It's possible that some things are available only via SDOs (CoE) though, but this is usually limited to up-front configuration settings and acyclic statistical and other informational data rather than data that would normally be read/written cyclically. Also note that some devices may not allow you to actually change the assignment, but all such CoE-enabled devices are required to accept writes to the assignment registers provided that they match the "correct" values. So make sure that they are being registered in the correct order (use "ethercat debug 1" and look at the syslog to see what order Etherlab is trying to write them in). > Anyway, at the end Twincat works and it would be good nice if etherlab could > behave as Twincat and map the domain in the same way, without the > needing of a special firmware. It should be possible, but you'll need to determine what is different about the configuration set in TwinCAT vs. what you're trying to set in Etherlab. After successfully configuring and communicating with the device in TwinCAT, export and review the ENI init sequence, and make your Etherlab application do the equivalent. _______________________________________________ etherlab-users mailing list etherlab-users@etherlab.org http://lists.etherlab.org/mailman/listinfo/etherlab-users
