# Source Tightening Properties

Parameter | Description
--- | ---
Name | The name issued to the source tightening.
Selector mode | 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: 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.
Max consecutive NOK per program | On: The batch counter increments even when a tightening operation fails. 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, there is no check performed for NOK tightenings. When reaching max consecutive NOK, the tool locks and the sequence execution is halted.
Batch control | Select how the source tightening is to be executed. The available options are: No batch control Running the selected tightening program repeatedly. Internal batch control For each program in the Identifier selector configuration section, set the batch size to be used when that program is selected. External batch control External systems can set the batch size using either Open Protocol or Fieldbus. The batch size must be set by an external system; if not set when a program is selected, the tool will be locked. When batch control is Internal or External, source tightening can be configured to: Lock tool on batch sequence completion When enabled, the tool automatically locks upon reaching the specified batch size. Increment on NOK When enabled, the batch counter increments for both successful and failed tightenings. External: Configure how many times a source tightening should be executed by using Open protocol or an external protocol. 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.
Use Joint IDs | Source tightening can be configured to attach a Joint ID to each result, enhancing traceability in data analysis software like ToolsNet. When Use Joint IDs is enabled, you can configure a Joint ID for each program in the Identifier Selector Configuration section. Empty Joint ID No Joint ID will be assigned to results from this selected program. Joint ID when not running batch The configured Joint ID will be attached to each result when the program is selected. If the program runs multiple times, it will use the same joint ID for all iterations. Joint ID when running batch Joint ID behavior varies based on its format. If the joint ID does not end with a number, the same joint ID is used for all tightenings in the batch. If the joint ID ends with a number, The number increments with each increase of the batch counter. The joint ID's ending number may not match the batch counter. Example: If the initial joint ID ends with 5, after two tightenings: The batch counter will be 2. The joint ID will end with 7.
