You should see the Status Monitor main screen like this:
Whenever the time for collection (specified for each individual CRVW3 in the
Schedule tab of Setup Screen , see Section 10.7.4 , Setting up Automatic Data
Collection
(p. 87)
) is reached on the LoggerNet computer’s clock, LoggerNet will
connect to the station automatically and collect data from it. You can observe
LoggerNet performing these tasks using the Status Monitor .
For each station, focus on the collection State ( Coll State column), the time
that data was last collected from the station ( Last Data Coll column), the time
that data will be collected next ( Next Data Coll column) and the number of
values collected (these will be non-zero when actual records get collected). By
highlighting a particular station, you can also force a data collection to occur
immediately using the Collect Now button. For more information about using
the Status Monitor , refer to Section 6 of the LoggerNet manual.
Check the Status Monitor on a regular basis (daily or weekly) to ensure that the
expected data is being collected from each CRVW3 station at the expected
time. The Status Monitor is a key application for ensuring the regular flow of
data on your network, so you should invest effort to be familiar with how it
operates.
When LoggerNet succeeds in collecting data from a station, it places that new
data into a file (which usually has a .DAT extension in the filename). This file
is specified in the Data Files tab for that station in the Setup Screen . See
Section 10.7.4 , Setting up Automatic Data Collection
(p. 87)
, and Sections 4.2
and 4.2.5 of the LoggerNet manual for more details. You can observe the file
modification date to ensure that data was written to the file at the expected
time. These files can also be opened and examined using the View Pro utility
(see Section 11.4.2 , Analyzing and Publishing Historical Data
(p. 94)
). Recent
collected data is also cached into a LoggerNet memory location for easy
sharing with LoggerNet client applications, such as the
Numeric Display
or
Graph
used in Connect Screen . The LogTool application can also be used to
confirm that table collection is working. See Section 6.2 of the LoggerNet
manual for more information.
The CRVW3 uses tables that operate like those found in programmable
dataloggers (CR6, CR1000, CR3000, etc.). The CRVW3 communicates these
