GENERATOR CHAPTER 5: STATUS
Figure 5-4: Tab pushbutton summary (left) and detailed view (right)
Only the tab pushbuttons that are not set to Disabled are shown in color; labels for the tab
pushbuttons are shown for both active and disabled pushbuttons if labels have been
configured. (Configure tab pushbuttons from
Device > Front Panel > Tab PBs > Tab PB1(X).)
When the actual button is pressed, the button on the screen is highlighted in blue and the
PB [X] PRESS operand becomes active. Although a disabled pushbutton can be pressed, no
action is taken and its operands are not activated. Pressing ESCAPE returns the screen to
Tab Pushbutton summary page. The Short Text for each Tab Pushbutton is used on the
Summary Page.
Pressing >> shows the next set of tab pushbuttons. For example, when in the page with
pushbuttons 1 to 4, pressing >> will navigate to the screen with pushbuttons 5 to 8. By
pressing >>, the user can cycle through all five pushbutton screens. To go from page 2 to
page 1, one must press >> 4 times to cycle through and navigate to page 1 with
pushbuttons 1 to 4. Alternatively, one can escape to the overall summary screen and
navigate to any desired page of pushbuttons.
