The emulator will allow you to test your View Designer project without having to download to physical Panelview hardware. Normally I would download my Trend Chart additions to my PanelView 5510, but here I want to make use of a feature in View Designer – the Project Emulator. Here, I have added four traces and assigned tags from my Compact Logix Controller tags. On the “Traces” tab, click on the “Add Trace” button to begin adding values to the Trend Chart. They are the values that are to be trended at runtime. Traces are what would also be called “pens” in trending terminology. Under the Properties tab on the right side of View Designer, I set my trend background colors, widths of lines and other basic properties to get my trend chart looking the way that I wish for it to display at runtime. Here I add the “Trend Chart” to my HMI Screen called “TrendData”
In the following screenshot, you can see the toolbox has a section called “TrendCharts” and a “Trend Chart” object that I will add to my blank screen. In my simulation project that I have covered for several weeks, I have now added another user-defined graphic page called “TrendData” in which I will add a Trend Chart to view at runtime. In today’s article, I’ll take a look at setting up a Trend Chart in Studio 5000 View Designer. Operators can monitor the direction of their process and better understand how things are controlling and operating, maintenance personnel can use trends to detect and troubleshoot problems and engineers can use them to tune controls and stabilize operations, just to name a few. While many times underutilized in an HMI, everyone involved in a manufacturing process benefits from trended data, or at least, they would benefit if they used it.
