5. Before actual data values can be displayed in the text pane, activate one of the following data collection modes (see
Figure 3 on page 47):
•
Click on the
[Get Once]
option button at the bottom of the right pane in the Text Display window. The current
value of the selected process parameter, as specified in the PanaView network tree, is displayed in the right pane
of the
Text Display window.
or
•
Enter an interval in the text box at the bottom of the right pane in the Text Display window, or check the Max.
Comm Rate box to collect readings as fast as the system allows (1 sec). Then, click on the
[Continuous]
option
button to begin collecting data for display in the right pane of the Text Display window.
Note:
Any value entered in the Interval text box is overridden if the Max. Comm Rate box is checked.
6. If the
[Continuous]
option was selected in Step 5 above, click on the
[Stop]
option button, which has replaced the
original
[Continuous]
option button, to terminate data collection.
The Text Display window may be left open while other tasks are performed, or it may be closed by clicking on the
lower
[X]
control button at the far right of the menu bar.
IMPORTANT:
If you click on the upper
[X]
control button at the far right of the PanaView title bar, you will exit
PanaView completely.
2.3.1a Displaying Multiple Process Parameters
The procedure for displaying a single process parameter in a text screen may be repeated to simultaneously display
multiple process parameters. To do so, proceed as follows:
1. Display the first process parameter in a text screen, as described in the previous section.
2. Repeat Step 1 for any desired additional process parameters, by double clicking on them in the PanaView network
tree. PanaView automatically tiles the multiple text screens in the right pane of the
Text Display window.
3. As in any standard Windows application, the multiple text screens may be resized by dragging their borders. Also,
the individual panes within a parameter’s text screen may be resized by dragging the borders within that text
screen.
4. To close an open text screen, right click anywhere within that screen (except in the title bar or the error section) and
click on the
[Remove]
option that pops up in the context menu.
Note:
After resizing or removing any of the multiple text screens, the default tiled layout may be restored by opening
the
“Window” menu (see the PanaView User’s Manual ) and clicking on the “Tile Output Displays” option.
