Inserting a Scope View The "General" property page shows the name of the currently selected Scope View. The name in the tree structure is the same as that shown here, and can also be altered here. The comment is included when the Scope View is printed. Properties Show Scope TCatScopeView can show a number of Scope Views at the same time. The ”Show Scope” check-box specifies whether the Scope View is displayed in online mode (recording). If this flag is not active, no channels are recorded in online mode, and can therefore not be displayed later either.
Overload prevention Since TwinCAT V2.8 Build 722 If the amount of unprocessed data exceeds a certain threshold value, then the Scope switches in offline mode automatically Standard & Ring Buffer There are basically two different methods to record the plot of a Scope View. If "Standard" is selected (default), the channels of the Scope View are recorded after the trigger signal for the time specified for the duration of the recording. The values are displayed from left to right. Once the recording duration has elapsed, online mode is automatically ended. Alternatively, the ring buffer can be selected. In this mode, recording continues until the online mode is ended explicitly.
In that case, the current value is always displayed at the right hand edge of the Scope View, while the old values are correspondingly shifted to the left. The "Displayed Length" refers here to the time period whose values are directly displayed in the Scope View. In offline mode it is also possible for older values to be displayed, where the "history length" is given by the recording duration. Refresh rate The refresh rate refers to the time within which the Scope View is updated. It should be noted that a fast refresh calls for higher computer performance. Scope View 12 Version: 1.1
