4.9 DISPLAY 31 - LOCATOR GRID
The Locator Grid is illustrated in Figure 4-14. It is used as a reference to determine the location of
the current display being viewed relative to the other displays configured in the display list. The Lo-
cator Grid is invoked by pressing and holding the F1 or F2 push buttons while viewing the current
display. (The current display should have been on the screen for a short time, otherwise the next
display in the list will appear.) The current display reappears when the F1 or F2 push button is re-
leased. The Locator Grid can also be viewed just like any other display if it is configured in the dis-
play list (see Table 5-15, System Module for the Number of Groups [B017], Number of Displays per
Group [B018], and Display List [B021-B084] datapoint definitions). Configuring the Locator Grid in
the display list does not eliminate the ability to momentarily invoke it as described above. Three
push buttons are required to function for the Locator Grid Display: F1, F2, and Mode/Alarm. The

, and F3 push buttons are not applicable. The grid in Figure 4-14 is typical for
Control Strategy 41, Four Loop Controller as described in Table 4-2, Generated Display Lists. It is
two columns (groups) by five rows (displays within group) for a total of 10 displays. The illumi-
nated cell in the display illustration indicates Four Loop CON0 - CON3 was the current display
when the Locator Grid was invoked. Notice that the corresponding grid location in the table is
shaded. The maximum size that any Locator Grid display can be is eight columns by eight rows for
64 cells (displays).
