# Source Tightening

Source tightenings link a specific tightening program to one or two identifier numbers depending on the configuration. When the identifier number is sent to the tool (by external digital signal), and, if required, the linked end fitting tool (TAG) or socket is used, the linked program will run over and over until a different signal is sent (or end fitting tool is attached, or socket is picked up). There is no batch counting.

To link separate lists to the virtual station, a source task must be assigned to the virtual station. Go to Integrated Controller Tool > Virtual Station in the home menu and select Task > Change task.
