- first write all relevant parameters in the TC variables. This can be done in a single OPC UA 'write' operation, The plugin will not check that all fields have been updated. This is under the repsonsibility responsibility of the OPC UA client.
- then activate the command
Trigger. This must be executed after the previous write command was sucessfully successfully completed.

Trigger | Boolean | co_ts | True: Triggers the TC with current values and current timestamp of the variables related to the same PIVOT object. False: Ignored Note that OPC UA clients do not need ot reset the Trigger to false between two TRUE writes operations. |
TBC: another option is (use a mask in trigger rather than using 4 booleans in parameters):

Common notes
- With
<PIVOT_ID>as provided inexchanged_data.datapoints[].pivot_idsection configuration. - All read-only variables have a
OpcUa_BadWaitingForInitialDataquality (0x80320000) initial value until a valid value is received from FledgePower. - All non-mandatory values will be set automatically by the server if not received from a south device.
- If a mandatory value is missing, then the whole PIVOT object is not updated.
- As a standard OPC UA server, all functional data are organized under the
Root.Objectsnode of namespace 0 ( nodeId =i=85). - All data are stored under the namespace 1. Its URI is configured in protocol "
namespaces" parameter.
