Section 5. Real-Time Tools
after associating the file, you may need to recompile the program file with a
version of Edlog that stores this information in the *.dld file.
If you are using Edlog Version 2.0 or greater and labels are still
not available for use, check Edlog’s Options | DLD File Labels
menu item and ensure that labels are being stored in the file
when the program is compiled.
NOTE
For CR1000, CR3000, and CR800 Series dataloggers, you can use the
Associate Program option (either from the Connect Screen’s Datalogger menu
or from the Setup Screen’s Program tab) to associate a TDF file with a
datalogger. TDF stands for Table Definitions File. When a program is
compiled for a CR1000, CR3000, or CR800 Series datalogger a
program_name .TDF file is created along with the original program file. This
file contains the table definitions for that program. Associating the TDF file
with a datalogger can be useful if communication is taking place over a slow or
unreliable communications link where the attempt to receive table definitions
back from the datalogger fails.
5.1.7 Data Displays
The Connect Screen’s Data Displays provide display screens to monitor
numeric values collected from the datalogger or to view the collected values
graphically.
Data being monitored in a data display is updated as follows:
Mixed Array Dataloggers
Final storage data from mixed array dataloggers is retrieved only when
data collection from the datalogger occurs (initiated manually from the
Connect Screen or based on a schedule). Therefore, the final storage
information on the data displays will be updated only as often as data
collection is performed for these dataloggers. Input locations do not have
to be scheduled for collection to be displayed. When connected, these
values are updated based on the update interval of the display (but limited
by how fast measurements are actually being made in the datalogger).
Table Data Dataloggers
When connected, data from table data dataloggers is updated based on the
Update Interval. (This is referred to as real time monitoring.) Note that
data can be updated no faster than the data values are being generated by
the datalogger. When not connected, data from table data dataloggers is
updated only as often as data collection is performed. (This is referred to
as passive monitoring.) Therefore, for input locations or public variables
to be updated when not connected, they must be included for scheduled
collection.
Updates to the displays can be suspended by selecting Pause Data Displays
from the Connect Screen’s Edit menu. This will stop the updates to all
displays even though new data may be coming in to LoggerNet.
