# Start Request

Start request enables the requirement of having a persistent connection between the tool and controller for an STB tool. This to make sure that the tool is always up to date with tightening program or batch settings, and with other settings on the controller, when performing tightening.

When Start request is set to On the tool gets locked if the tool loose connection with the controller. This means that if the tool loses connection in the middle of a tightening or a batch sequence, the tool will finish the ongoing tightening and then stop. The tool will be locked until it has reestablished the connection.
