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.
