The ExecutingSubstateMachineType, a Substate machine of Executing State of the SystemOperationStateMachine, represents a mechanism for describing the stopping behaviour of the system. This can be used to display the stopping behaviour in more detail depending on the StopMode commanded.
The overview of the ExecutingSubstateMachine with all transitions is shown in Figure 8.

The ExecutingSubstateMachineType is formally defined in the table below.

The states of the ExecutingSubstateMachineType are described in Table 71.
Table 71 – ExecutingSubstateMachineType State Descriptions
|
StateName |
Description |
|
Running |
The system is available, but cannot started because a preparation is needed |
|
Stopping |
The system was commanded to stop (internally or via Stop() and the needs some time for necessary background processes before entering the Ready state. |
The transitions are described in .
