FMS Events Data Group
The "FMS Events" (FMSEvent) data group is used to send event data to the FMS. It gets its data from the "Hist - Events" (HistEvent) data group which read events from the Emerson event file. Each event includes an Emerson point tag or DEID from the Meter Configuration data group. If the tag is found in the associated Meter Configuration data group, it is deemed applicable to the current meter. Units come from native event history data group, not from the device template file.
Data Group Mapping
The mapping between Emerson and FMS items is contained in the fmsMaps/configItems section of the device template file. Additional items not associated with configuration items can be added to the fmsMaps/eventItems section. These are identified by Emerson point tag.

<fmsMaps> <configItems> … <eFMS_DEVICE_EVENT_TYPE_DATETIME tag="Clock_1.Time"/> <eFMS_DEVICE_EVENT_TYPE_DEVICE_SPECIFIC tag="Station_%station%.*"/> … </configItems> </fmsMaps> |
Device specific event items may contain a wildcard in the tag. For example, the tag "DP_%meter%.*" will include events for this DP meter.
Substitution strings in point tag names are supported for meter number (%meter%) and station number (%station%), and are filled using values specified by the user in FMS Configuration data group.

<!-- By default, event tags that are not mapped to FMS data items are recorded as device-specific events. Set omitUnmappedEvents to "true" to override this behavior. --> <FmsEvent niceName="FMS Events" baseOrd="1" maxCnt="24" ordLabel="Meter" omitUnmappedEvents="false"> <dgElements/> <uccRecvParms type="string"> <SDate desc="Start date" required="true"/> <EDate desc="End date" required="false"/> </uccRecvParms> </FmsEvent> |
Unmapped Events
The "FMS Events" (FmsEvent) data group includes an attribute omitUnmappedEvents. If this flag is set to "false" or is missing, a device specific event will be recorded for any event tag that matches the instance portion of a tag in the Meter Configuration data group.
Example
If the Meter Configuration data group includes an item with tag "DP Meter_1.OBJ_NAME", any event tag beginning with "DP Meter_1" will be included as a device specific event.
