Redlines

Color a value on a table or a schematic when it passes a threshold.

A redline changes the background color of a value when the value passes a threshold. Use redlines to show an operator which values are near or outside their limits.

Redlines are available on value cells in tables and on value symbols in schematics. A redline only changes the color of the value and notifies no one. To alert an operator, use an Arc alarm.

Add a redline

1. Turn on editing for the table or the schematic.
2. Select the value cell or the value symbol, then press V to open the component toolbar.
3. Open the Redline tab. On a schematic, it is inside the Properties tab, next to Telemetry and Style.
4. Under Bands, click Add band.
5. Set the threshold and the color of the band.

Each new band starts one step above the highest band, in the warning color, then the error color.

Bands

Each band has a threshold and a color. A band paints the values at or above its threshold (≥) and below the next higher threshold. Values below every threshold show the item at the bottom of the list: No fill, or Fill when you set a background on the Style tab.

For example, a pressure value has two bands: yellow at 500 and red at 600.

Two bands cannot have the same threshold; the Console marks them Duplicate threshold. To remove a band, click on the band.

To make a band blink between its color and the fill while the value is in it, click the flash button on the band.

Transition

Under Options, Transition sets how the color changes between bands:

• Steps -> the color changes at each threshold.
• Smooth -> the color blends from the color of a band at its threshold to the color of the next band at the next threshold. The highest band is a solid color.
