Value Gauge
Overview
The Value Gauge shows the value of the output specified in the Input property according to the format specified in the Format property. The Justification property specifies whether the text is aligned to the left, right or centre of the bounding rectangle.
It is important to select the background colour of the value gauge to be the same as the colour of the background the gauge is over. Failure to do so may result in corruption of the value displayed.
The value gauge has an optional warning mode that changes the colour of the gauge when a warning limit for the input is exceeded or if a secondary channel is logically ’true'.
Properties
In addition to Standard Gauge Properties , the following properties may be configured:
| Property | Description |
|---|---|
| Colour Mode | Enables changing the colour of the gauge based upon the value of a channel. |
| Alarm Limit | In Limit Mode, specifies an upper limit for the input value, above which the Alarm Colour shall be used. |
| Alarm Colour | Colour to use when in the alarm state. |
| Alarm Flash | The gauge will alternate between the warning colour and the background colour whilst the warning is active. |
| Colour Input | In Logic Mode, Allows selection of a channel, which when non-zero places the gauge in the alarm state |
Special Formats
The Special Format property can be used to display internal system values. See Value Formatting .
The Channel Name and Channel Units Special Format values will cause Dash Design to replace the value gauge with a Text Input Gauge when programming the display containing the input channel name or units. This can be useful if creating Gauge Groups where the channel name, value and units should be shown; setting the Input channel property on the group will assign the value and also update the channel name and units.
