ToolsTalk 2 provides Statistical Process Control (SPC) function to handle SPC configuration of the controller and presentation of SPC result data from the statistical calculations in terms of charts. The statistical calculations are performed on controller and the results are provided to ToolsTalk 2 for presentation in the ToolsTalk 2 client.

By configuring the SPC function within the controller, it is possible to simplify and do the work directly on the controller without the need of external software. The charts data are generated on the controller.

Statistical calculations are based on tightening results stored in the controller.

Statistical calculations are done on a Virtual Station level, depending on the tightening program selected and used for that specific Virtual Station.
