Write Response (Slave Master)
Read Request (Master Slave)
Read Response (Slave Master)
From this example you can see how the write / read sequence typical for the PROFIdrive profile delivers
the queried value on reading it. In this case, the write-response contains no data. It merely indicates that
the write request was received on profibus terminal 8640 DPV1 ME02. The read delivers the data first.
Example 3
Manual acknowledgement of peripheral errors (writing on the DPV1 field bus node, Slot 0, Index 4)
Write Request (Master Slave)
Write Response (Slave Master)
Here, the data block is only important in the request. The response indicates that the command was
received.
Example 4
Writing on object 5FFF, sub-index 0 of an RS232 on Slot 4
