# Creating a Source Tightening

1. Select a controller in the Plant structure workspace .

2. Go to the Sources tab.

3. Select Add, the Create new source configuration dialog window opens. Choose Tightening from the drop-down menu then select Add.

4. Issue the Source Tightening with a name.

5. Set the number of Max 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 source tighteining execution is halted.

6. Select which Batch Control is to be used from the drop-down menu.

   Internal batch control: Configure how many times a source tightening should be repeated.

   External batch control: Configure how many times a source tightening should be executed by using Open protocol or Fieldbus. Any configuration change clears the source tightening so 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.
