Shows the last occured alarm from the Profinet device.
It gives information about what type of alarm it is and
from what slot/subslot it comes.

Alarm priority, low or high

Indicates whether there exists remaining alarms

Diagnosis appears Alarm
A diagnosis appears alarm signals an event within a submodule,
for instance overtemperature, short circuit, etc.
The content of the alarm is defined by the Diagnosis ASE for this type.

Process Alarm
A process alarm signals the occurrence of an event in the
connected process, for instance upper limit value exceeded.

Pull Alarm
A slot signals the withdrawal of a submodule/module or change
in configuration (reduction).

Plug Alarm
A slot signals the insertion of a submodule/module, a new need
for parametrization, or a change in configuration (addition).

Status Alarm
A status alarm signals a change in the state of a submodule,
for instance run, stop or ready.

Update Alarm
An update alarm signals the change of a parameter in a submodule
e.g. by a local operation or a remote access.

Redundancy Alarm
A redundancy alarm signals the fault of one IO controller to the
remaining IO controller for redundant IO ARs.

Controlled by supervisor
A slot signals the logical withdrawal of a submodule by the
IO supervisor. The actions shall be according to the Pull Alarm.

Released Alarm
A slot signals the logical insertion of a submodule by the IO supervisor.
The actions shall be according to the Plug Alarm.

Plug Wrong Submodule Alarm
A slot signals the insertion of a wrong submodule/module or a
change in configuration (addition).

Return of Submodule Alarm
A slot signals that a submodule is ready to switch its IOCS/IOPS from
"BAD" to "GOOD" again without new parameterization.

Diagnosis disappears Alarm
A diagnosis disappears alarm signals a disappearing diagnosis event
within a submodule. The content of the alarm is defined by the
Diagnosis ASE for this type.

Multicast Communication Mismatch
A multicast consumer submodule signals that communication
relationship to the associated multicast provider is failed.

Port Data Change Notification Alarm
A port submodule signals that port data has been changed.

Sync Data Change Notification Alarm
An interface submodule signals that synchronization data has been changed.

Isochronous Mode Problem Notification Alarm
The application signals that problems with isochronously execution
have been detected.

Furthermore, manufacturer specific alarms may be used and alarms
are reserved for profile specific definitions.
