Setting languages
UA tags of the String type can be localized with OPC UA, that is, texts (values for the UA tag)
can be available in different languages for the server. For example, localized texts can be
available for DisplayName (Name of the node) and Description (Description).
In the "Languages" area of the "Configuration" tab you can, for example, influence the
language of the texts returned by the server as follows:
In the "Languages" area, enter a number of languages that the server transfers to the client
during connection setup.
The language or the local ID ("language code") associated with it that you enter in the first
line is the language preferred by the client.
•
If the server can provide the UA tag in the requested language, it is transferred to the
client.
• If the server cannot provide the UA tag in the requested language, it checks whether it can
provide the UA tag in the language you have entered in the second line (first substitute
language).
• The server works its way down the list, and when it can provide neither the requested
language nor a substitute language, it will provide the default language.
