There are two issues here that cause the Workspace control included with the 2009 web-version of the Embedded Data Logger not to work:
1. As you saw, the Workspace control was compiled with LabVIEW 2009, and therefore it cannot be loaded into the LabVIEW 2011 Run-Time Engine, which NI VeriStand 2011 uses. The control would have to be resaved in LabVIEW 2011. However...
2. The Embedded Data Logger that ships with NI VeriStand 2011 is different than the web-version for NI VeriStand 2009. The control will not work without code modifications, some of which are fairly involved.
For now I would recommend interacting with the Embedded Data Logger directly through its channels, such as the trigger, log command and status channel. The channels have descriptions that you can view in the Channel Data Viewer to help you make sense of the enumerated values for the various commands.
