The Variable LastTransitionReason provides the reason for the LastTransition. The EnumValue and ValueAsText of this 0:MultiStateValueDiscreteType are described in the table below.

The states of the IdleSubstateMachineType are described in Table 65.
Table 65 – IdleSubstateMachineType State Descriptions
| StateName | Description |
| StandBy | The system is available, but cannot be started because a preparation is needed |
| GettingReady | The system was commanded to get ready (internally or via GoToReady() and the needed preparation to get ready is done in this state by the system. In the GettingReady state the system prepares what is to be done (e.g. switching on intermediate circuit) to be ready to start execution in a next step. Typically, all task controls which participate in system functionality are in in Ready (or Executing) state before calling the GoToReady() method on system level. When the preparation is done successfully the IdleSubstateMachine will be left and the Ready state of the SystemOperationStateMaschine will be entered. The ongoing preparation can be interrupted by calling the GoToStandBy Method. |
The transitions are described in .
Table 66 – IdleSubstateMachineType Transition Descriptions
| TransitionName | Description |
| StandByToGettingReady | Changes from StandBy to GettingReady because the preparation was initiated. |
| GettingReadyToStandBy | Changes from GettingReady to StandBy because the preparation was aborted. |
