[9-23] Complete state diagram according to PackML standard

The condition for switching the state transitions is that the result of the

Command_StateBusy(xAllOrSlaves:=TRUE) method is FALSE, except for the transitions "Abort" and

"Stop".

• The "Stop" transition enables a transition to the "stopping" state from all areas without

Command_StateBusy (xAllOrSlaves:=TRUE) being =FALSE.

• The "Abort" transition enables a transition to the "Aborting" without

Command_StateBusy (xAllOrSlaves:=TRUE) being = FALSE.

• All other state transitions can be found in the following section with the related

Command_CtrlCmds _xxx. The state transitions in detail: Command_CtrlCmds() method

9.3.2 Methods for changing over the state transitions

The following section provides an overview of all methods in the ApplicationTemplate PackML:

Changing over a single transition

[9-24] Example: Changes the transition "Start" from"Idle""Starting".

• Thus, the state machine then is in the active "Starting" state.

•The xCmdChangeRequest value of the method cause a switching of the transition by means of

a positive edge.

• As long as one of the slave modules has the xBusy status, a changeover of the state machine is

prevented.
