Charts Tool

This tool handles all .rwtv files. These are the trend/chart definition files. All widgets and chart views are loaded from files from this tool. The .rwtv files are possible to configure in a Widget, and as a view. They can be accessable from dashboard as Widget content, when a Widget is clicked, or as a stand alone Link Icon.

• The Signal attribute is configured for the signal.

Auto Unit for Analog Signals

The Unit (and auto axis selection based on unit) is auto fetched from database if:

• The Unit is empty.
