So, in my case all i need to do is mapping RPDO's and TPDO's in my new slave device B, is that correct ? Now, do i really need to to add an extra SDO server in slave node A as Mr Freitag mentioned ? Sorry gents, If i annoy you. Also i have another final question. Is there a way to provide security to the network as it's very open network (CANopen)?. Without gateway is that possible ?. The reason i'm asking is; I don't want anyone to tap into my network and start sending messages or start writing SDO messages using any CAN interface device with free software available online. -Arun -- Archives and useful links: http://groups.yahoo.com/group/CANbus Subscribe and unsubscribe at www.vector.com/canlist/ Report any problems to <[email protected]>
