9.3 State machine in detail
The top machine control module MM_MachineControl_PackML is the master module and...
• ...is located at the first/top position in the MachineModuleTree (MMT)
• ...controls the state machine of all lower-level slave machine modules.
The state transitions triggered by the master module have an impact on the lower-level slave
machine modules.
