B.2 Status

In the ExtrusionDeviceType, the Variable Status has been replaced by the two state machines MachineryItemState and MachineryOperationMode (see OPC 40001-1). The state machine MachineryItemState is extended by a sub state machine ExtrusionExecutingSubState.

As the status information is now split into two states, there is no one-to-one relation between the old states in version 1.01 and the new ones in version 2.0. For example, MALFUNCTION and MAINTENANCE which are separate states in version 1.01 can occur at the same time with the MachineryItemState OutOfService and MachineryOperationMode Maintenance when there is an error during maintenance.
