•
VM8 through VM1 velocity RMS data is burst at 08:20.
•
VM9 is collected at 08:30. VM9 through VM1 enveloped acceleration Pk-Pk is
burst at 08:40.
•
VM9 through VM1 velocity RMS data is burst at 09:20.
•
VM10 continues this pattern, building up a total of 12 measurements to be sent
with each burst. And so on through the day.…
•
VM24, the last measurement of the first day, is taken at 23:30. VM24 through
VM13 enveloped acceleration Pk-Pk is burst at 23:40.
Thus ends the timeline. Not shown is the activity on the following day when VM24
through VM13 velocity RMS data is burst at 00:20.
If the Period entries and the cyclic update interval do not evenly
divide 24 hours, then the remaining hours do not carry over into
the next day or change the timing of events.
Command 9 Example
The second example illustrates Command 9. If the network is using a non P+F gateway
that does not support caching Command 93, then you must use Command 9 to burst
the sensor’s Envelope Pk-Pk, Velocity RMS, and Temperature measurement results to
the gateway’s cache (with less accurate date / time stamps).
