    Hi!
    Does the EPL protocol support SDO Block-transfer besides expedited and segmented transfers?
    Thanks

      Hi,

      The protocol supports expedited and segmented transfer. What do you mean with SDO block transfer?

      You can find the full POWERLINK specification on the EPSG homepage:
      http://www.ethernet-powerlink.org/en/downloads/technical-documents/

      Best regards,
      Wolfgang

    The SDO Block up/download protocol is described in the CiA CANOpen draft standard.
    The original canopen sdo segmented protocol is such that the server responds to each request, while in the block sdo protocol case the client transmits the whole data in its SDO's in a burst like way.
    Actually I think that this is what have been implemented in EPL as I can see now in the specification.
    Thanks anyway.
