4.2.8.1 Graphical front panel
Phasor diagrams and metered data can be displayed.
The update rate of metered values is 500 ms.
A phasor page for each configured AC Source and up to five user-configurable metering pages can be displayed. The
phasor pages are not configurable. Each phasor page shows a phasor plot and numerical values of all currents, voltages,
and symmetrical components of a single AC source.
The Annunciator and Metering pages can be configured to display data. Each has a user-configured number of rows and
columns. Each cell can include either configurable static text or the value of a selected FlexLogic operand, FlexAnalog
operand, or actual value. The font size, background and foreground color, and actual value formatting are configurable
independently in each cell, as is the number of rows and number of columns on each page.
To display a metering page, press the Home pushbutton, then the Metering Tab pushbutton. The first metering page
opens. The Tab pushbuttons display any other metering page, as do the Up, Down, Left and Right pushbuttons. Phasor
pages are listed before tabular pages. The current page is highlighted with a blue Tab pushbutton.
Each phasor page has a name, which consists of the value of the SOURCE # NAME setting appended with " Phasors."
Phasor pages that have no configured CTs or VTs do not have a Tab pushbutton, and phasor pages that have no
configured cells cannot be displayed.
