9.9 Triggering alarms

Example: Triggering / forwarding alarms - within a machine module

Program line for triggering an alarm within the machine application:

[9-29] Example: Trigger Alarm1 of FB AlarmsA

There is a predefined coupling between the alarm handling and the state machine for the alarm

reactions "Stop" and "Abort".

• The alarm reactions trigger a PackML command "STOP" or "ABORT" in the module in which the

error occurred.

• These alarm types automatically deactivate the module which has no direct impact on the

master module.

• The alarm reaction types of the slaves and the own module can be defined individually so that

the desired state change in the state machine is possible.

Example: Triggered alarm with "Abort" reaction type in case of module 1

The following example shows what happens if an alarm of the "Abort" reaction type is triggered at

a slave module. The example contains two lower-level slave modules.

scMAL.AlarmsA.xAlarm1Trigger:=True;

• The state machine is located in the "Execute".

• The current state of the state machine is

highlighted in red.

• An alarm of the "Abort" reaction type is

triggered in the Module_1 slave module. The

Al. 1. input is highlighted in red.
