RealTime Displays

The updates in RealTime displays are triggered by changes in the dynamic properties of objects assigned to the display. All RealTime displays in DataStudio share this feature giving the user instant and reliable access to real-time data (The minimum time between updates is based on the TCP settings of DataStudio, configured in the General Settings menu). This section covers the use and configuration of the RealTime displays in DataStudio.

RealTime Grid

The RealTime Grid display provides an overview of real-time information from data producing items including the object’s current state, its last value and the quality of the value. The display can be opened from the Open menu (Shortcut Ctrl+R) or from the context menu of an object in a model panel (Shortcut Alt+R).

RealTime Trend

The RealTimeTrend is a trend view displaying the currently incurring data from the selected data source. This means the trend starts blank (without accessing potentially available history data) and gets “filled” over time. The display buffers a configurable amount of data samples. The display can be opened from the Open menu (Shortcut Ctrl+T) or from the context menu of an object in a model panel (Shortcut Alt+T). The visualization of each individual trend lines can be changed in multiple ways using the Legend box at the bottom of the display. Using the arrow icons it is possible to navigate back through the trend to the data at the oldest timestamp. The incoming data samples can also be recorded and then exported into an MS Excel sheet.
