Chapter 3. Logging Data
3.7 Viewing PC Log Files (cont.)
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
• [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 65) for a list of the parameters specified for logging.
•
Click on the Contents tab (see Figure 21 on page 65) 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).
