This document provides instructions for using the Renumber Tools Add-in for ESPRIT. The add-in allows users to quickly change tool numbers based on operation order, starting from a given number and incrementing sequentially. It can also update length compensation registers and station numbers to match. The add-in requires a valid ESPRIT license with bit 90 activated. It provides options to set the starting number, increment, update offsets, and restart numbering for each turret. Support is available by contacting DP Technology.
