Adding a Trending Display
You can use the Trend Viewer to create, configure, and plot real-time or historical data trends from various sources, such as alarms and historical data through OPC UA, and other data point connections through the FrameWorX™ server.
For the Start-Up Guide, you will create a graph that displays the Tank Temperature.
Verify the Historical Data Logger service is running.
