Light

Open

The Light symbol reflects varying conditions by changing color based on predefined thresholds. This symbol serves as a visual indicator of specific parameter levels. The thresholds can be configured either through static limits or dynamically by referencing other PI Tags. When the monitored value is within the designated safe range, the light remains in a default color. However, as the value approaches or exceeds predefined limits, the light transitions to different colors, providing immediate visual feedback about the parameter's status. This dynamic light symbol efficiently communicates critical information and helps users identify anomalies or potential issues at a glance.

Starting the Control

To start the control click on the “Assets” button in the upper left corner of the PI Vision display.

In the upper part select “weruLight” by clicking on it.

Afterwards the desired asset/attribute from the asset tree could be added to the display via drag and drop. The Light symbol appears on the display and can be used.

Configuration

In the configuration, a default color can be specified in the upper area.

In addition, "High Limit" and "Low Limit" values can be stored. If these are exceeded or fallen short of, the color of the control changes to the one specified there.

If the option "Use Extreme Limits" is activated, two additional limits can be set.
