The following conditions must be met to transfer a value:
•
The data point is assigned to a topic in the configuration.

Time of the data transfer and quantity of the transmitted data
Triggering the data transfer is different for the two target systems:

The transfer time is controlled via trigger, refer to the section Data points (Page 78).
You specify the time when the values of data points are transferred to the broker for each
data point with the "Trigger".
The following data are transferred together to the broker as soon as the value of a data
point is pending for transfer:
–
AWS / Azure / IBM Cloud
Transfer values of all data points of a topic
– MindConnect IoT Extension / Other Cloud
Transfer values of all data points of a group

The OPC UA server executes the read and write jobs of the OPC UA clients.
No additional settings can be made for the server.
