This OPC UA ObjectType represents the current configuration of a machine related to a Manufacturing Execution System (MES). It is formally defined in Table 35.

The StandstillReasons Property represents an array with a list of the standstill reasons from which one is selected by the operator in the case of a standstill. The used StandstillReasonType is defined in Table 36.

LockedByMES means that this StandstillReason has been set or modified by the MES and so this may not be changed by the machine. |
StandstillReasons shall support at least 10 entries.
The MES shall be prepared, that the list includes standstill reasons not defined by the MES (e.g. added by the operator on the machine). The user of the interface shall ensure unique Ids among all standstill reasons. To ensure consistent statistics, a change of the meaning of already assigned standstill reasons should be avoided.
The StandstillReasonsLockedByMES Property indicates if the list StandstillReasons has been modified by the MES and may not be changed by the machine.
NOTE: The parameter LockedByMES in an item only locks this StandstillReason whereas StandstillReasonsLockedByMES locks the complete array (that means also that no items can be added by the machine).
The MESUrl Property represents a URL to display a webpage generated by the MES in a web browser integrated in the machine.
