DOWNLOADING DATA
PLMIII records many types of data. The PLMIII PC
software is designed to download the data from a
whole truck fleet. Instead of creating one data file for
each truck, the PC software combines all the data
from many trucks into one database on the hard
drive of the computer. The software then allows
users to query the database to create custom reports
and graphs. Data for individual trucks or groups of
trucks can be easily analyzed. This same data can
be exported for use in other software applications like
word processors and spreadsheet applications.
As the database grows, performance of the PC soft-
ware for analysis will slow down. It may be helpful to
periodically export data. For example, query the
database to show the oldest quarter, month, or half
year and print out a summary report. Then export the
data to a compressed format and save the file in a
secure location. Once the data is exported, delete
the entire query results from the database. If neces-
sary, the data can easily be imported back into the
main database for analysis at a future date. Remov-
ing this older data will improve performance.
The PC software downloads the data from the pay-
load meter into a single Paradox database. The data
from all the trucks is added to the same database.
Downloading the payload meter can take several
minutes. The data is added to the database on the
laptop used to download.
To move the data to another computer, a query must
be run to isolate the particular data for export. Do not
press the operator switch on the dashboard while
downloading

To download the payload meter:
1. Connect to the payload meter and start the PC
software.
2. From the main menu, select "Connect to Pay-
load Meter". The PC will request the latest sta-
tus information from the payload meter. The
number of haul cycles and alarms will be dis-
played.
3. Select the " Begin Download" button. The PC
will request the payload and alarm data from the
payload meter and save it into the database.
This may take several minutes. A progress bar
at the bottom will show the approximate time
left.
