Siemens SINAMICS G115D User Manual

To reduce the transfer volume, there is not only the "normal" "data exchange" PIV
mechanism, but also the "Read data" and "Write data" commands.
• Data exchange:
– Control → converter request
– Converter → control response
• Read data:
The converter sends a read command, and the data of the last exchange request or write
request is transferred from the converter to the control.
• Write data
Write OK: → 53 hex.
Because the PIV transfer protocol speci󹪝es the transfer direction independently, all
parameters can be transferred as data exchange request/response. Requests for reading and
writing data are included primarily to reduce the transferred data volume for the repeated
reading or writing of parameters.
