8.19.5.4 ReadDataByPacketIdentifier Sequence Example.
In the sequence of examples below (Tables 200 thru 204):
•
The tester sends a ReadDataByPacketIdentifier request with the sub-function parameter = $03
(scheduleAtMediumRate) to schedule two DPIDs.
•
The tester then requests an additional DPID to be scheduled at a fast rate while the previous two DPIDs
still are transmitted at medium rate.
•
One of the medium rate scheduled DPIDs is stopped by a sub-function parameter $00 with the DPID in the
request.
•
The tester then sends a ReadDataByPacketIdentifier request with the sub-function parameter = $01
(sendOneResponse) to read one DPID (one DPID is still scheduled at fast rate and another at medium
rate).
•
Finally the tester sends a ReadDataByPacketIdentifier request with the sub-function parameter = $00
(stopSending) without any DPIDs in the request message.
8.19.5.4.1 First Sequence: Schedule Two DPIDs at Medium Rate.
•
DPIDs: $10 (6 data bytes), $30 (4 data bytes).
