The following figure depicts the Multi-Emitter Generation Application state machine.

Uninitialized—The MEG Application is running but the system configuration is not applied.

To enter Uninitialized state:

• MEG Application is first started.
• Make a change to the System Configuration while the system is in Idle state.
• Call Clear Errors while in the Error State.
• Call RESET from the Idle state.

To exit Uninitialized:

• Call INITIALIZE to load a system configuration and transition to Idle state when the configuration is successfully applied.
• An error occurs and transitions to the Error state.

Idle—A valid system configuration is applied. The system is ready to run a MEG command file.

To enter the Idle state:

• Call INITIALIZE from the Uninitialized state.
• Automatically returns to Idle when a MEG command file is complete.
• Call STOP while in the Running state.

To exit the Idle state:

• Call RUN to execute a MEG command file and transition to the Running state.
• Call RESET to transition to the Uninitialized state.
• An error occurs and transitions to the Error state.

Running—The system is executing MEG commands from the command file.

To enter the Running state:

• Call RUN from the Idle state.

To exit the Running state:

• The MEG command file completes processing and returns to the Idle state.
• Call STOP to stop MEG Command processing and return to the Idle state.
• An error occurs and transitions to the Error state.

Error—The system has encountered an error.

To enter the Error state:

• An error occurs in any other state.

To exit the Error state:

• Call Clear Errors to return to the Uninitialized state.
