Hi,

Maybe I've misunderstood your question, but Twincat3 doesn't have anything to do with etherlab ... Instead, if you're trying to read or write SDO to your canOpen slaves trough etherlab master and EL6751, you can't do it because Beckhoff has implemented this only trough their ADS protcol (AoE in this case) and this is not actually supported by etherlab master.

Bye,
Thomas.

Hello,

I am interfacing Refu drive via EL6751 CANOpen with TwinCAT 3. I would like to read/write SDO's of drive. I have found the read/write logic on Beckhoff information system but they have not given information on how to map PLC variables with SDO's.

could anyone help me to map plc variables with drive SDO's in TwinCAT 3?

​Note: I have eds file from drive supplier

Thanks in advance,
Best regards,
Venkat
