If the variable UserStructureIdentifier indicates manufacturer specific diagnosis information, the variable ManufacturerData contains the manufacturer specific diagnosis data.

The Message variable of the Event and the HelpText variable 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 Severity variable of the Event must be dependent on the Maintenance and the QualifiedChannelQualifier variables.

The Severity is 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 Maintenance variable is provided, the following mapping is used for the Severity value:

Maintenance	Severity
FAULT	1000
MAINTENANCE_DEMANDED	612
MAINTENANCE_REQUIRED	362

If the QualifiedChannelQualifier is provided, the Severity value 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 Severity value:

Bit	Severity
