A higher-level system would like to know the status/state/condition (e.g., collision) of the GMS, when manual intervention is required, the current error message, what measures have to be taken in case of intervention to

  • plan the next jobs
  • keep usage statistics
  • plan maintenance
  • assign service
  • calculate key performance indicators (e.g., OEE [ISO 22400-2])
  • archive data
  • verify the reliability of the measurements
  • send warnings, if necessary.

Figure 11 and Figure 12 show a typical communication between GMS, operator, and high-level system to retrieve dynamic machine data as a sequence diagram.
