Communication protocol 125
SDO Upload
Through this service the client of an SDO requests the server to
prepare to upload data to the client.
The multiplexor (index and subindex) of the data set to be
uploaded is indicated to the server. The service is confirmed. The
remote result parameter will indicate the success of the request. In
case of a failure, an Abort SDO Transfer request has to be
executed. In case of success, the size of the data to be uploaded is
confirmed. In case of successful expedited upload, this service
concludes the upload of the data set (identified by the multiplexor)
and confirms the corresponding data.
