The OPC UA Laser Systems interface can be used to display a forecast of the next manual interventions to be performed on the laser system. With the help of this predictive information about the next pending maintenance intervention, the maintainer and his colleagues can optimize and plan their next activities on the laser systems. Consequently, time and money may be saved as down- and lead times can be taken into consideration (see chapter 7.3.1 and 7.3.2).
