FloBoss 107 Instruction Manual
1-16 General Information Revised June-2017
Extended History archiving provides a monitoring resolution for the
FB107 that is similar to a chart recorder. You can configure Extended
History to archive up to 25 history points with archiving intervals at 1, 2,
3, 4, 5, 10, 12, 15, 20, 30, or 60 second or minute intervals.
The FB107 has a 60-minute historical log for every history point. The
Minute Historical Log stores the last 60 minutes of data from the
current minute. Each history point has Minute Historical Log entries,
unless the history point is configured for FST-controlled logging.
The FB107 has a total of 35 days of hourly historical logs available for
every history point. The Hourly Historical Log is also called the
Periodic database. Normally, the Hourly Log is recorded at the
beginning of every hour, although you can configure it for either the
beginning or end of every hour. The exceptions are FST Minute and
FST Second logging.
The time stamp for periodic logging consists of the month, day, hour, and
minute. The exception is for FST Second logging, in which the time
stamp consists of the day, hour, minute, and second.
The FB107 has a total of 35 or 60 daily historical logs for every history
point. The Daily Log is recorded at the configured contract hour every
day with a time stamp that is the same as the Hourly Log. Each history
point has daily historical log entries, unless the history point is
configured for FST-controlled logging.
The Min / Max database displays the minimum and the maximum
values for the database points over a 24-hour period for today and
yesterday. You can view the Min / Max historical, but not save it to
disk.
The FB107 has configurable archive times that, in turn, determine the
number of entries. You can configure Extended History to archive up
to 25 history points with archiving intervals at 1, 2, 3, 4, 5, 10, 12, 15,
20, 30, or 60 second or minute intervals.
1.4.2 Alarm Log
The alarm log contains the change in the state of any alarm signal that has
been enabled for alarms. The system alarm log has the capacity to
maintain and store up to 240 alarms in a “circular” log. The alarm log has
information fields that include time and date stamp, alarm clear or set
indicator, and either the tag name of the point or a 14-byte detail string in
ASCII format.
In addition to providing functionality for appending new alarms to the
log, the alarm log allows host packages to request the index of the most
recently logged alarm entry. Alarm logging is available internally to the
system, to external host packages, and to FSTs.
