Managing MQTT settings
If MQTT client mode is active in the OPC server, the context menu of nodes and devices shows the menu item "MQTT settings".
This menu item opens the group tag settings window for working with MQTT.
Under "Settings" changes, you can enable a way to change the receiving and publishing settings for tagged topics. When Publish and Subscribe are enabled, settings for adjusting the topic name appear.
Publish on change - data transmission mode. True - change transfer, False - transmission with polling cycle.
Fields Topic Prefix, Topic, Topic Index, Topic offset, Topic Postfix allow you to form a unique topic for each tag.
Topic Prefix - the text at the beginning of the topic name of each tag.
Topic - the main topic name of each tag.
Topic Index - start index for the topic for the first tag.
Topic offset - topical index offset for the following tags.
Topic Postfix - the text at the end of each tag topic.

The Subscribe mode settings are the same.
The Export and Import buttons allow you to export and import flagged tags for further editing by third-party software, such as Excel.
