Description of Attribute Semantics of Values
Returns the number of overall data Fixed depth: 320
records (at the fast update rate)
that the buffer currently holds.
Returns the number of (low Fixed depth: 640
resolution) overall data records
that the buffer currently holds.
Returns the number of dynamic Fixed depth: 64
data records that the buffer
currently holds.
The rate at which Trend Overall Multiples of 100 ms
data records are stored, based on
Default of 10
the fast update rate.
Range: 1...32767
The rate at which Trend Dynamic Multiples of 100 ms
data records are stored, based on
Default of 100
the fast update rate.
Range: 10...327670
Defines overall record update rate Equal to Attribute 17
for use in alarm storage, which is
Range: 1...32767
based on the fast update rate.
Activate Trend Storage on a per Bit enabled control. See
channel basis Enable" under Attribute Semantics.
Reference to Voted Alarm Object,
including OFF option.
If latching, the alarm data buffer 0: Not latching
does not update on subsequent
1: Latching
alarm excursions unless the latch
has been reset.
Overall, post-trigger setting for the Range: 0...8
100 ms update rate - set in eighths
Default: 2 (25%)
of the total buffer length
(80 / 320 records)
Overall, post-trigger setting for the Range: 0...8
user configured update rate - set in
Default: 2 (25%)
eighths of the total buffer length
(160 / 640 records)
Overall, post-trigger setting for the Range: 0...8
dynamic data records - set in
Default: 2 (25%)
eighths of the total buffer length
(16 / 64 records)
Range: 0...4294967295
Range: 0...4294967295
Range: 0...4294967295
DWORD 3 is only partially Range: 0...1023
populated with measurements,
hence the lower range.
