The user would like to monitor information about a specific MachineryItem, like the state or operation mode, for example to get a quick overview over the current state and bottlenecks (localization of errors), to recognize trends or to determine the relevant times (productive time, standby time, etc.) for subsequent KPI calculations (e.g., for calculating reliability and availability). Further information for the KPI calculation might be necessary.

The user would like to monitor different aspects of a MachineryItem like its status, health, process and consumption.

That leads to the requirements:

• The state of a MachineryItem can be accessed (see section 12).
• The operation mode of a MachineryItem can be accessed (see section 13).
• All monitoring information of a MachineryItem shall be easily accessible (see 16).
• All status information of a MachineryItem shall be easily accessible (see 16).
• All health information of a MachineryItem shall be easily accessible (see 16).
• All process information of a MachineryItem shall be easily accessible (see 16).
• All consumption information of a MachineryItem shall be easily accessible (see 16).

In Annex C an example is given, on how the state and operation mode can be used as base for KPI calculations.
