Method for the hybrid-automated monitoring of production machines
First Claim
1. A method for operating a production machine in order to generate production information, which comprises:
- setting up an evaluation status model having a plurality of evaluation statuses, each one of the plurality of the evaluation statuses having precisely one respective time account corresponding thereto;
setting up an interpretation status model having a plurality of statuses, transitions between the plurality of the statuses of the interpretation status model being established in accordance with events that can be picked up on the production machine;
assigning the plurality of the statuses of the interpretation status model to the plurality of the statuses of the evaluation status model; and
while operating the production machine, increasing the time account of an applicable one of the plurality of the evaluation statuses, which is applicable at a particular time, by an amount corresponding to a time period in which the production machine is in the applicable one of the plurality of the evaluation statuses.

Abstract
The method is for generating production information, such as capacity, reliability, or capacity utilization information, while hybrid-automated monitoring a production machine. An evaluation status model having a number of main statuses and an interpretation status model having a number of operating statuses are set up, with precisely one time account corresponding to each main status and transitions between operating statuses being established in accordance with events that can be picked up on the production machine. After that, operating statuses are assigned to main statuses and the time account of the main status applicable at a particular time is increased during the operation of the production machine by an amount that corresponds to the time period in which the production machine is in the main status concerned. Moreover, the number and sequence of changes in status are stored as a history.
