Datalogging and Charting
The 4848 Controller comes equipped with a charting
and datalogging program. This program cannot be
run simultaneously with the control program, but
once the user is satisfied that the controller is set,
the control program may be closed, allowing the
charting and datalogging program to run. The mod-
ules on the 4848 may still be modified manually at
the physical panel during datalogging and charting.
1. Open the ParrCom.exe file. No installation is
necessary.
2. At the main program screen, select "protocol >>
set PC" (if you have already done previously, you
may skip this step). Ensure that the following
values are set:
Baud: 9600
Data length: 8
Parity: even
Stop bit: 1
ASCII: RTU
Click OK to return to the main screen.
3. At the main screen, select "Program >> Record-
er". The Recorder screen will come up.
4. Select the proper address for the Devices you
wish to chart. The primary temperature has ad-
dress 1, and each additional module would have
an address numbered 2-4 going from left to right
on the physical 4848 Controller.
5. Click the Save button and save a REC
file to an appropriate place on the PC.
When the chart is generated, it will write
to this file.
6. When you return to the main Record-
er screen, notice that the Save button
is depressed. Hit the Start button to
begin recording.
7. The chart will show the process values of each
module represented. As the values change, the
chart will automatically scale to show the values.
8. When you wish to stop recording, click the stop
button. The chart has already been
saved in the REC file created in step 5.
You may view the chart by clicking the
recorder button.
9. You can convert the file to a TXT file for export to
a spreadsheet as well.
Converting a Chart File to TXT
Once a chart REC file has been created, you can con-
vert it to a TXT file for export into a spreadsheet.
1. Insert the 576M CD into the CD-ROM. Locate the
conversion file at “ \software\convert.exe”. Copy
it to the PC.
2. Open the convert.exe file. No installation is
necessary.
3. Click the "CONVERT" button. Locate the REC file
to be converted, and click "Open".
4. The conversion program will create a new TXT
file in the same location as the REC file with the
name "CONVFILE.TXT".
