9.8.2 Acknowledging alarms

Acknowledging alarms deletes all messages/causes defined as subject to acknowledgement from

the Alarm List. The acknowledgement of alarms can be activated by means of the following

procedures:

1. Permanent activation: Within the module application via the following program command:

2. Activation for one cycle: Via the Command_AlarmQuit method, rising edge FALSE

TRUE. The

method sets the xQuitErrors input to TRUE for one cycle.

If multiple alarms occur, they cannot

be acknowledged individually. Further information:

9.8.3 Acknowledging alarms: Response in the machine module

The xErrorQuitActive output on the L_EATP_ModuleErrorHandler_PackML block can be used within

a module application to acknowledge alarms on an integrated function block.

dwAlarmPriority Assign priority for alarms of the same error reaction type.

xAlarmAckNeeded Acknowledgement behaviour:

Information (yes/no) stating

whether the alarm tripped is to be

acknowledged.

The acknowledgement behaviour cannot

be changed for all alarm reaction types.

Characteristic Description Further information

ErrorHandler.xQuitErrors := TRUE; //error acknowledgement active as long as value =

TRUE

•The SetAlarms is to be extended

by one function block.

•The MAP_EmptyModul_App1 FB

has to be extended by the

corresponding declaration.

•The xAlarmTrigger[1...4] method

has to be connected to the module

application.

• Assign the corresponding

parameter to the respective alarm

input:

•Number,

•text,

•priority,
