END_IF
• CASE instruction
• Module's intrinsic/subordinated
module status enquiry by method

Querying an active warning
• IF condition
• Query the module's intrinsic
warning
IF AlarmInformation.eReaction=
L_EATP_AlarmReactionType.Warning THEN
// Do something if warning is active
ELSE
// Do something else if warning is not active
END_IF
Querying the setpoint state of the master
• IF condition
• signal-based with method Status-
StateRequested
IF Status_UnitStateCurrent
(MM_Address:=L_EATP_CONST.OWNID) =
L_EATP_States_PackML.Execute THEN
IF Status_StateRequested(MM_Address:=
L_EATP_CONST.OWNID) = L_EATP_States_PackML. Completing
THEN
// Do something if actual state is EXECUTE and set
state to COMPLETING
