GLOSSARY
CALLBACK - Telecommunication with a
datalogger where communication is initiated by
the dataloggerusually in response to an alarm
or event. Callback is also used where it is
impractical to call the datalogger but the
datalogger can call out.
Final Storage - A more permanent portion of
datalogger memory where processed Input
Location values are stored. The values are
typically the result of processing measured
values over time, like averages, maxima, etc.,
over the last minute, hour, day, etc. These
values are retrieved for archival and analysis.
The values remain in the datalogger until it is
full at which time the oldest values are written
over as new values are stored.
Final Storage Area 1 or Area 2 - The CR10(X),
CR10, and CR23X have two independent Final
Storage Areas. Use of the second area is
determined by the datalogger program. Data
can be collected from either or both areas.
Input Locations - The addresses in the
datalogger memory where the direct results of
measurements are temporarily held. Typically
these are the values viewed in Monitor or Graph
Mode to determine current status. These
values are not necessarily the same values
retrieved when data is collected.
Network - A network refers to one or more
dataloggers and the communication device
used to communicate with them. It should not
be confused with a computer local area
network.
Node - Another name for a datalogger or
modem in a network.
Task - An entry on the DEVICE MAP
representing a program scheduled for
execution. Scheduling of execution can be
done on a regular interval or following a call to a
datalogger.
