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).
The function of the icons at the top of the RealTime Grid display are explained in the table below. The information columns that are visible as default upon opening the display can be configured in the General Settings or the visible columns in the current display changed using the column selctor in top left corner of the grid.

RealTime Trend
The RealTimeTrend is a trend view displaying the currently incurring data from the selected data source.

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.
