HasProperty	Variable	HelpText	LocalizedText	PropertyType	Optional

If the variable UserStructureIdentifierindicates manufacturer specific diagnosis information, the variable ManufacturerDatacontains the manufacturer specific diagnosis data.

The Messagevariable of the Event and the HelpTextvariable are retrieved from the GSDML file. If the message includes a dynamic format string, this is replaced by the ExtChannelAddValue.

For an active alarm the Severityvariable of the Event must be dependent on the Maintenanceand the QualifiedChannelQualifiervariables.

The Severityis divided into the 4 categories shown in the following table:

Category	Severity Range
Fault	750 – 1000
Maintenance demanded	500 – 749
Maintenance required	250 – 499
Advise	2 – 249

If the Maintenancevariable is provided, the following mapping is used for the Severity value:

Maintenance	Severity
FAULT	1000
MAINTENANCE_DEMANDED	612
MAINTENANCE_REQUIRED	362

If the QualifiedChannelQualifieris provided, the Severityvalue depends on the bit set in the UInt32 value of the QualifiedChannelQualifier. The bits 0 – 2 are not used.

The following mapping is used for the Severityvalue:

Bit	Severity
31	1000
30	937
29	875
28	812
27	750
26	725

6.3.4.2 PnAssetChangedEventType

This event is fired when a new asset (controller, device, real module, real submodule or asset) is detected, an asset was removed, or the data of an asset changed. The event is fired on the object with the change.

An asset change for a device, real module or real submodule means that its I&M data (PnIdentificationType) has changed. See section 5.3.2.6“Asset change detection” for details.

HasProperty	Variable	AssetType	PnAssetTypeEnumeration	PropertyType	Mandatory
HasProperty	Variable	AssetChange	PnAssetChangeEnumeration	PropertyType	Mandatory

The SourceNode variable of the event includes the NodeId of the asset object.

The Severity variable shall be set according to the following table.

Severity	Cause
10	Minor important asset detected
20	Normal important asset detected
30	Asset of vital importance detected
110	Minor important asset changed
120	Normal important asset changed
130	Asset of vital importance changed
1100	Minor important asset removed
1200	Normal important asset removed
1300	Asset of vital importance removed

6.3.4.3 PnTopologyChangedEventType

This event is fired when the CommLinkToreference between two EthernetPortTypeobjects is created, removed or changed. The event is fired by the PnPortTypeobject.

This means that the physical network topology has changed.

The Severityvariable (inherited from BaseEventType) shall be set to 1.
