# Source Tightening Overview

The tightening menu shows a list of Source Batch and Source Tightening configurations. Separate lists can be linked to a Virtual Station by going to the Virtual Station in question, and in the Task properties selecting Choose. There, a Source can be chosen as a task. Source tightenings link a specific tightening program to an identifier number. When the identifier number is sent to the controller, the linked program will run over and over until a different signal is sent ..

Parameter name | Description
--- | ---
Name | The name issued to the Source Tightening.
Description | The description of the Source Tightening.
Lock tool on batch sequence complete | On: The tool is locked when the batch sequence is completed. Off: The tool remains unlocked when the batch sequence is completed.
Socket selector | Control: When set to Control, an external source selects a tightening program by requesting an identifier number. The identifier number is linked to a corresponding socket in the socket selector, and by lifting the socket the tightening program is selected Confirm: In Confirm mode, the socket selector cannot be used as a controlling source. In this mode identifier numbers are linked to both a tightening program and a specific socket (indicated in an additional column in the list). When an identifier number is requested (by an external signal), the corresponding socket is prompted in the socket selector and the tightening program is activated when the operator lifts the socket (other sockets are disabled). If no socket is specified (that is, set to 0 in the Socket column), the tightening program is activated directly and the socket status is ignored.
Increment on NOK | On: The batch will advance even if a NOK tightening is performed. Off : Set Max consecutive NOK for the tightening. The batch will only advance if a successful tightening is performed.
Max consecutive NOK | Set the number of consecutive NOK results to be allowed. If the value is set to 0, then there is no check performed for NOK tightenings. When reaching max consecutive NOK's, the controller locks the tool and the sequence execution is halted.
Batch control | Select how the source tightening is to be executed. Internal: Configure how many times a source tightening should be repeated. External: Configure how many times a source tightening should be executed by using Open protocol or Fieldbus. Any configuration change clears the source tightening to start over from a clean and known state (the batch count in the batch will be reset to 0). Ongoing tightenings are able to finish before the changes take effect.

Command | Description
