C.2 Example interpretation for ISO 22400

Table 68 proposes how KPI time elements according to ISO 22400-2 can be set using the combinations of MachineryItemState, MachineryOperationMode and HLS-ConditionState. These ISO 22400-2 KPI time elements can be used to do KPI calculations.

Note 1: If condition state is order registered but in planned break down time period based on operation calendar then KPI time element has to be actual break down time (ABRT).

Note 2: Technological effects e.g., speed losses based on wait for feeds or wait for drains have to be analysed on SCADA or machinery level.

Note 3: If an added value activity is included in setup mode period, then the added value time has to be calculated as APT (APT=PQ*PRI) based on produced quantities and AUST has to be reduced based on this calculated APT.
