• 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.

Example

Querying the current state

• IF condition

• Subordinated module status
