Working with the Sources Tab
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 sync mode.
Source Batch is used to select a batch sequence, a series of sync modes.
