Hi

I have a Trend control where the logged tags are logged on a hysteresis. 

In the Ruler Control I would like so show the actual value of the tag that is being logged. 
But I am only able to show the last archived value, and if there haven been no change in the value since the trend page was opened the value is not shown. 

Is there any way to show the actual value of the logged tag in the Ruler Control, or at least the last logged value?

Thanks :-) 

To display the actual value of the logged tag in the Ruler Control, or at least the last logged value, you can follow these steps:

1. Configure the Trend Control: Ensure that your trend control is properly configured to display both current and logged values. This involves setting up the trend areas and axes, and defining the trends with their respective tags.

2. Use the Ruler Function: The Ruler function in the trend control allows you to display the coordinates of the intersection point with a trend. When the trend update is stopped, the trend values are also displayed in tooltips. Ensure that the trend companion is configured with "Ruler window" display mode.

3. Update Display Settings: If the trend is not updating continuously, configure a second trend in the same trend display with the trend type "cyclic real-time". This ensures that the current trend is shown continuously upon calling Trend View. Check the following FAQ: How can you have a trend archive displayed continuously updated after calling Trend View?
