• As long as a state of a slave module has xStateBusy= TRUE , the changeover of the state machine

is prevented. An exception is the triggering of the commands "Abort" or "Stop".

By default, the module is set to the respective state with the command in the first cycle of state .

If all tasks are done in this state, xStateBusy can be reset again to enable the changeover to

another state.

The following program line enquires the state:

"xAllOrSlaves:=TRUE" also enquires the own module, "xAllOrSlaves:=FALSE only the slaves of the

module.

9.6 Stater machine: Query examples

This section shows (by the use of program examples) how...

• ...to access the state machine.

• ...to query the states.

Command_StateBusy(xStateBusy:= TRUE)

Status_StateBusy(xAllOrSlaves:=TRUE)

Objective/call Example

Querying the current state

•IF condition

• Subordinated module status

enquiry by method

(example: Slave, address = 1)

IF Status_UnitStateCurrent (MM_Address:= 1)=

L_EATP_States_PackML.Execute THEN

// Do something if Statemachine is in state EXECUTE

END_IF
