# System Functionality

The POWER FOCUS system sends the tightening program and the batch size to the tool, where it is stored and executed. The tightening result is then sent back to the POWER FOCUS. See schematic figure below.

The tool has the same basic functionality as other tools, but due to the nature of the wireless communication, where the tightening data is stored in the tool, all features in the POWER FOCUS software may not be available for this tool.
