4.3.7 State machine

Each machine module has an own state machine. The state machine of a mode can be created

individually: By deactivating single states in the entire state machine.

4.3.7.1 State transitions - overview

The following status diagram illustrates the possible state transitions of the state machine:

[4-8] State machine in the ApplicationTemplate PackML

The current state of the state machine is highlighted in red.

• Active state in the illustration: "Idle"

• "Idle" corresponds to the "Waiting" state and is thus highlighted in yellow.

The colouring in the state machine distinguishes the following states:

• Yellow: Waiting state

• Green: Acting state

• Blue: Dual state (can be "waiting" or "acting")

The "waiting" states "Stopped", "Aborted" and "Execute" cannot

be deactivated.

Deactivating a state simultaneously switches off the respective (outbound) transitions. If it is the

"Wait" state, it also switches off its "Active" state.
