Module description

The Fugitive data are transient status points that are transmitted by the station only on "1" controlwith value = 1.

The fugitives data are acquired from the station like normal status point. The fugitives data transient status points are acquired from the station like any normal status point. When a fugitive transient status point is received (value 1), it is normally transmitted forwarded 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 forwarded to the centers north service with a modified timestamp (+1ms). 

However, on CG GI response they must systematically always be sent to 0.

Configuration

The

...

following attributes are read from the Exchanged data configuration:

• pivot_subtypes has "transient" in the list.

Filtering rules

R1

Format

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. 

Filtering rules

R1 : Generation of a new datapoint when a fugitive status point is received (value opposite to the reception, adding 1ms in the timestamp).

R2 : Only status points configured as transient in subtypes are managed processed by the plugin, ie pivot_subtypes has "transient" in the list.

R2 : When creating a new datapoint, add 1 ms to the timestamp of the received transient status point.

Data processing

Input

This module is designed to work on status points in pivot format.

...

filter plugin expects readings to be a pivot model status point datapoints.

The module uses the identification (Attribute "PIVOTTS.GTIS.Identifier") of the data to determine if it is a fugitive identify the transient status point to process.

Output

If the value "1" is received from the station, the module transmits the value to the center. If the status point is fugitivetransient, a new datapoint is copied created with :

• its value to 0
• Timestamp incremented by 1ms.

The generated new data generated in the format takes the form are:

• For a simple point 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 point 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"
