Working with the Sources Tab
Controller features, such as the Low Reaction Tightening Strategies and controller-wide functions among others, require licenses distributed through the Functionality Management System (FMS). Whereas configuration of features is possible without specific licenses, the assignment and use of those features will require the correct license to be installed on the controller. Please refer to Licenses (FMS) for more detailed information on licenses.
The selection of a task is done in the Task menu in the Virtual station configuration workspace.
External signals used as tasks for tightenings are configured in the Sources 
tab. Sources are accessories, or similar, connected to a virtual station. Two types of source tasks are available:
Source Tightening task
Source Batch task
Source Tightening is used to select a single tightening program.
Source Batch is used to select a batch sequence, a series of tightening programs.
