For TC, the filter receives OPCUA reading (from north) and creates a corresponding PIVOT reading. The created PIVOT reading format is given in FLEDGE WIKI.

The reading input is expected with the following JSON equivalent format:

{
   "control_object":{
      "co_type": <string>,
      "co_test": <int>,
      "co_ts": <int>,
      "co_se":  <int>,
      "co_negative":  <int>,
      "co_qu": <int>,
      "co_cot": <int>,
      "co_id": <string>,
      "co_value": <depends on data type...>
   }
}

TBC : Something does not work. The "do_value" (reply) will be sent by a south service, is it intended to be received as a full PIVOT value? What will be the reading sent from south to North in this case? Is it supposed to be a reading that is compatible with filter and opcua?.  And in that case, should we ignore all fields except "do_value" or create a full read-only variable set on the OPC server for each TC?

The content under <Root> will convert the OPCUA command objet to a pivot object as follow:
