Attributes of BaseEventType
Attribute Data type Mapping with respect to SINU‐
MERIK
M/O Description
EventId String Unique node id generated from
SINUMERIK system.
M EventId is generated by the Server to
uniquely identify a particular Event Notifi‐
cation.
The EventId shall always be returned as
value and the Server is not allowed to re‐
turn a StatusCode for the EventId indicat‐
ing an error.
EventType NodeId It is always set to ‘CncAlarmType’. M The EventType shall always be returned as
value and the Server is not allowed to re‐
turn a StatusCode for the EventType indi‐
cating an error.
SourceNode NodeId Alarm source identifier provided
by SINUMERIK system.
M SourceNode identifies the Node that the
Event originated from. If the Event is not
specific to a Node, the NodeId is set to null.
SourceName String Supported alarm source names
are HMI, NCK, and PLC.
M SourceName provides a description of the
source of the Event. This could be the
string-part of the DisplayName of the Event
source using the default locale of the serv‐
er.
If it is not possible for a CNC system to pro‐
vide this information in detail, the Source‐
Name should provide the main component
responsible for this alarm (e.g. CNC, PLC,
or even Channel).
Time UtcTime Alarm time stamp M Time provides the time of the Event occur‐
red. Once set, intermediate OPC UA Serv‐
ers shall not alter the value.
ReceiveTime UtcTime Alarm time stamp of the server. M ReceiveTime provides the time the OPC
UA Server received the Event from the un‐
derlying device of another Server.
Message Localized Text Reading attributes via
(SLAE_EV_ATTR_MSG TEXT)
M Alarm Message provides a human reada‐
ble and localizable text description of the
Event.
Severity UInt16 Reading attributes via
(SLAE_EV_ATTR_SEVE RITY)
M Severity of the event message. The range
of values of the severity is from 1 to 1000,
where 1000 corresponds to the highest se‐
verity.
LocalTime TimeZoneDa‐
taType
Offset and the DaylightSavingI‐
nOffset flag
O LocalTime is a structure containing the Off‐
set and the DaylightSavingInOffset flag.
The Offset specifies the time difference (in
minutes) between the Time Property and
the time at the location in which the event
was issued. If DaylightSavingInOffset is
TRUE, then Standard/Daylight savings
time (DST) at the originating location is in
effect and Offset includes the DST correc‐
tion. If FALSE, then the Offset does not in‐
clude DST correction and DST may or may
not have been in effect.
