- All types not listed in this table are not supported in current version.
- The current implementation provides a default mapping rule for each known type, but some new rules might be added in the future and configured using the "
alternate_mapping_rule" option in its parameters.
Converting monitoring data types
Filter interface
The "plugin_ingest" call will convert each "reading" of "reading_set" as follow:
...
Reading key | Content |
|---|---|
| PIVOTTS.GTIS | Tele SignalStatus Point |
| PIVOTTM.GTIM | Tele Measurement |
| PIVOTTC.GTICNot supported yet | Command or Set Point |
<type> conversion table:

The content under <Root> will convert the IEC 104 data objet to a pivot object as follow:
...
IEC104 NORTH step:
If the Datapoint configured in the exchanged data has not IEC104 timestamp typeid
Then we create an ASDU with a typeid with no timestamp
If the Datapoint configured in the exchanged data has IEC104 timestamp typeid
Then we create an ASDU with a timestamp typeid, ASDU timestamp = do_ts And subtituted = do_ts_sub
