xPC Target

Changing Access Levels to the Web Browser

The Web browser interface allows you to set access levels to the target application. The different levels limit access to the target application. The highest level, 0, is the default level and allows full access. The lowest level, 4, only allows signal monitoring and tracing with your target application.

1. In the Simulink window, click Simulation Parameters. On the Simulation Parameters dialog box, click the Real-Time Workshop tab.

1. Access levels are set in the System target file box. For example, to set the access level to 1, enter

   • xpctarget.tlc -axpcWWWAccessLevel=1
     

   The effect of not specifying -axpcWWWAccessLevel is that the highest access level (0) is set.

2. Click OK.

The various fields disappear, depending on the access level. For example, if your access level does not allow you access to the parameters, you do not see the button for parameters.

There are various access levels for monitoring, which allow different levels of hiding. The proposed setup is described below. Each level builds on the previous one, so only the incremental hiding of each successive level is described.

Level 0 -- Full access to all pages and functions.

Level 1 -- Cannot change the sample and stop times. Cannot change parameters, but can view parameters.

Level 2 -- Cannot start and stop execution of the target application or log data.

Level 3 -- Cannot view parameters. Cannot add new scopes, but can edit existing scopes.

Level 4 -- Cannot edit existing scopes on the Scopes page. Cannot add or remove signals on the Scopes page. Cannot view the Signals page and the Parameters page, and cannot get scope data.
