9.13 "Rkv" Notes
1 Archives (only, not resets) are forced regardless of configuration, capturing
any unarchived data from the previous session.
2 Archives and resets are scheduled (immediately, without a "period-end"
delay) only for the initial setting of the wallclock; a "five-minute" event causes
no scheduling. This ensures capture of any flow that has occurred prior to the
initial clock-set.
3 Event occurs only when one or more of the following bits are changed:
o
Bit 2, "Barometric pressure units"
o
Bit 5, "Process input out of range use last good"
o
Bit 12, "Analysis is packed in module"
o
Bit 13, "Analysis is packed over backplane" (1756 and 1769 platforms
only)
4 A change to Meter Control Options bit 15, "Meter enable", imposes these
adjustments to the normally-scheduled archives/resets:
o
Upon meter enable, cancel any scheduled archives (no data yet to be
archived), but leave in place any scheduled resets.
o
Upon meter disable, cancel any resets (for inspection and so on.; reset
will be rescheduled upon subsequent enable), and force archiving of both
files regardless of configuration (so that a disabled meter never has any
pending unarchived data).
5 Events occur only if Meter Control Options bit 10, "Treat analysis as process
input", is clear.
