Signal access via TwinCAT 3 Scope

TwinCAT 3 Scope enables access to all variable groups for which at least read ADS access was enabled, see Tc Interfaces in Simulink. To use the Target Browser for configuring the Scope, the option …_CreateSymbols must be selected under Tc Interfaces in Simulink. Without the corresponding symbol information, the signals to be captured have to be configured manually in Scope via Index group and Index offset.

Alternatively, Scope can be started via the corresponding icon directly from the TwinCAT development environment (XAE). In the drop-down window of the block diagram browser, the button Show in Scope is shown for each available signal when the module instance runs on the target system.

The signals can also be conveniently dragged into the Scope configuration using the right mouse button (drag & drop) from the drop-down menu (bar on the right in the diagram above) or from the blue signal lines in the block diagram (main window in the diagram above). The right mouse button can also be used to drag a whole block into the Scope configuration, in order to record all inputs and outputs for this function block.
