The Fugitive data are status points that are transmitted by the PA station only on 0=>1 "1" control.
The fugitives data are acquired from the PA station like normal status point. The fugitives data are acquired from the PA station like normal status point. When a fugitive status point is received (value 1), it is normally transmitted to the north service. A new datapoint is then generated by the module with a value of 0 and is transmitted in the same way to the centers with a modified timestamp (+1ms).
...
The status points are declared in the "Exchanged data". A property "datapoints.pivot_subtypes" allows to define the nature of a status points. If it is declared as "transient", the plugin must perform the processing associated with this type.
The "datapoints.pivot_id" property corresponds to the identifier of the status point. The plugin is configured with "Exchanged data".
Pivot model interaction
Input
The module uses the identification (Attribute "PIVOTTS.GTIS.Identifier") of the data to determine if it is a fugitive status point to process.
Output
For each value 0=>1 If the value "1" is received from the APstation, the module transmits the value to the center. If the status point is fugitive, a new datapoint is copied with :
- its value is to 0
- its timestamp is incremented (+1ms)Timestamp incremented by 1ms.
The new data generated in the format takes the form :
- For a simple data type :
- PIVOTTS.GTIS.SpsTyp.stVal = False
- PIVOTTS.GTIS.SpsTyp.t.SecondSinceEpoch (incremented timestamp)
- PIVOTTS.GTIS.SpsTyp.q.Source = "substituted"
- PIVOTTS.GTIS.TmOrg.stVal = "substituted"
- For a double data type :
- PIVOTTS.GTIS.DpsTyp.stVal = "off"
- PIVOTTS.GTIS.DpsTyp.t.SecondSinceEpoch (incremented timestamp)
- PIVOTTS.GTIS.DpsTyp.q.Source = "substituted"
- PIVOTTS.GTIS.TmOrg.stVal = "substituted"
