6.2 Retrieve dynamic machine status

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.
