3.6 Viewing PC log files
After one or more PC log files have been created, the logs
may be viewed by using PanaView as follows:
1. You can access PC logs in two ways:
• From the new meter browser in PanaView, expand the
network tree and click on the PC logs option. If you
have created one or more logs, the tree will appear
similar to Figure 22 below. Double-click on the log
name to open the log, or
• Pull down the output menu (see Figure 13 on page
32 ), and click on the log browser option. advance
to the PC logs dialog box as described in previous
sections. A screen similar to that shown in Figure 23
appears.
Figure 22: Expanded PC logs option
Figure 23: Selecting a log file from the log browser
Notice that each of the log files in Figure 22 and Figure 23
has a traffic light icon next to its name. These icons indicate
the current status of the log as follows:
•
Red light - log has not run to its specified stop time but
has been manually stopped
• Green light - log is currently running but is not yet
complete
2. In the log browser, after you highlight the name
of the desired log file, the following option buttons
become available:
• [Start] - resumes logging if the log is currently stopped,
or [stop] - stops logging, if the log is currently running
• [Delete] - permanently deletes the log file
• [Open] - opens the log in the
PC log window
3. Click on one of the option buttons listed in step 2 above.
You can monitor the progress of an ongoing log in several
ways:
• Click on the
log items tab (see Figure 21 on page 33 ) for
a list of the parameters specified for logging.
• Click on the contents tab (see Figure 21 on page 33 )
for a list of all the data points logged to date for the
parameter currently highlighted on the log items tab.
• Click on the [graph] option button to display a graphical
representation of the data logged to date.
NOTE: The graph is displayed in its own window, which is
opened on top of the PC log window. For instructions on
using the graph log window, refer to the graphing output
section in Chapter 2 of the PanaView User’s manual .
• Click on the [refresh] option button to update the
information shown on the contents tab and in
the graph log window. Any data logged since the
last use of the [refresh] option button is added to
the list and to the graph.
Remember that only two parameters per channel may
be graphed, and that the same two parameters must
be graphed for each channel of a multi-channel graph
display. When you have finished viewing the graph, click
on the [close] option button to close the graph window
and leave the log running.
4. To terminate the logging process, simply click on the
[stop] option button, which has replaced the original
[start] option button. (The stop time automatically
appears in the PC log window.)
Because a PC log has no specific “ stop time ,” the log
will continue to run until it is manually stopped (unless
the PC is turned off or you run out of hard drive space).
