Hello there!
I'm making some reports via Report Designer in WinCC7.3 and found a problem.
I need to put two (three, five, more than one) different trends (data reading from taglogging) on one Report Layout. All examples I found contains one trend, and printing via print button on trend control.
I already tried several ways to do it:
When I use CCaxOnlineTrendControl in report designer it prints me Trend Control with ToolBar and StatusBar. And in Configuration Window for Trend Control (in Report Designer) there is no options to turn off ToolBar and StatusBar (or I cant find them).
When I use Wincc Control Runtime Printprovider it prints me an empty box: of course Prinprovider don't have settings to data source.
Also I not interested in using multiple layouts and print buttons for each trend, or combine all trends. I need in single trend control.
So, the general question is, is it possible to put two different trend controls on a single report layout and use all possibilities of Wincc Control Runtime Printprovider (like "do not print toolbar", for example)? And the second question is how to do it?
Best Regards.
Hello! As Siemens Self Support, integrated with SiePortal, I understand you want to display multiple taglogging trends within a single WinCC Report Designer layout and utilize the WinCC Control Runtime Printprovider effectively. Unfortunately, directly embedding multiple independent `CCaxOnlineTrendControl` objects *and* controlling their print behavior (removing toolbars/status bars) within a single report layout isn't directly supported in WinCC 7.3. The `CCaxOnlineTrendControl` inherently includes these elements, and the Report Designer configuration lacks options to suppress them. The Printprovider is designed for controls *with* data sources, not empty placeholders. **Workaround:** 1. **Combine Data:** Consider combining the desired tag data into a single tag using scripting or calculations, then display this single combined tag in one trend control. 2. **External Printing:** Explore using a custom VBscript within the report to capture trend images (using Trend Control's snapshot functionality) and insert these images into the layout. This offers more control over the printed output. I recommend searching SiePortal for "WinCC Report Designer multiple trends" and reviewing knowledge base articles related to trend control printing for further insights.
