9.8 Alarm handling (error handling)
The ApplicationTemplate PackML contains an alarm handling for providing alarms. The alarm
handling defined by default can be changed individually. Errors/warnings/information can be
defined in the module applications (MAP) of the machine modules.
The alarm handling has the following functions:
• Forwarding of alarm states within the MachineModuleTree (MMT).
• An application-global alarm list with the current alarm state of all machine modules contained
in the MMT.
• The alarm handling is connected to the logbook of the controller, so that the error messages can
be viewed in the logbook.
9.8.1 Defining alarms
The SetAlarms method defines the alarms with the corresponding properties in the respective
module application.
For changing the alarm handling, the ApplicationTemplate PackML provides the FB
L_EATP_Alarm_PackML. Application-specific errors can be triggered at the xAlarmTrigger input.
[9-28] Insert further instances of this FB if more than four error inputs are required per instance.
An alarm can be defined on the FB by the following characteristics:
The FB L_EATP_Alarm_PackML has four inputs xAlarmTrigger[1...4] for setting alarms. One alarm
each can be set per xAlarmTrigger input.  L_EATP_Alarm_PackML ( 98)
Characteristic Description Further information
wAlarmID Unique alarm number (ID). 16 bit alarm number, data type: WORD.
dwAlarmValue Detailed alarm information: For each
alarm, an additional attribute of
DWORD type can be used which (in
connection with the alarm number)
can be interpreted.
For a "Drive Error" group alarm, for instance, the
detailed alarm information of the corresponding
controller can be used.
sAlarmMessage Text description of the error. The alarm text is stored in the table of attributes. The
alarm text always is to be used if no higher-level
mechanism for implementing the error number in
national languages is activated (example: Higher-
level visualisation).
dwAlarmCategory Category/type of the alarm.
eAlarmReaction Alarm reaction: Can be selected from the list.
