Thank you for your strong support.
This problem is in my SDK, so I will ask my SDK manufacturer.

I have developmented the opc ua server and verified it by using OPC UA Browser and UaExpert.

I was able to see a new created event(it means self made) which inherited the Base Event Type in UaExpert.
However I haven't seen it in OPC UA Browser.
On the other hand, the newly Event was appeared in "select event fields" window.
Do I need to configura something? Or should I add some parameter(something to trigger) to my Event?
Could you give me some advice?

Best Regards,
Kento

For example in Ubuntu the 'hosts' file does have a line that says
127.0.1.1 COMPUTER_NAME_HERE

conf.xml etc. 'localhosts' do not matter, they are connection address (and we prefil few common ones there), for that is it is ok, ApplicationURI has nothing to do with those, it is just a network-unique identifier for any OPC UA application (and they must be unique) and are also used for creating ApplicationInstanceCertificates.

We cannot test every distribution, basically we officially support (and test) only Ubuntu, but it should run on equivalent distributions. Regarding the error please ensure your machine has a hostname/computername set (see e.g. what 'hostname' returns on the command line). The value 'localhost' is not a valid hostname regarding OPC UA for forming ApplicationURI as they must be unique within a network.

The OPC UA Browse application window opens, but then the wheel with the inscription loading spins endlessly. It is impossible to work. There is nowhere to enter the address, the window is clean.

Yes, sorry forgot to reply, that was an issue on my end, trying to fix that now that I understand the problem. Thank you for the help!

Best regards,
Miikka

Thank you for the quick response!

I have sent the requested information. Thank you.

Reading enumeration values returns just the numeric identifier of the enumeration value in the current version of Browser, which is 5.0.0-173. This will be improved in a future release to include both the numeric and the text value.

However, writing should work the same way for both standard and custom enumerations, so the Write Value dialog should have a droplist for selecting a value for both AxisScaleEnumeration and UserRating.

Would it be possible for you to send the NodeSet containing the UserRating Enumeration DataType to uabrowser-support@prosysopc.com so that we could check if there is anything odd about it? If sending the NodeSet is not possible, could you show us the value of DataTypeDefinition Attribute for UserRating? If this Attribute doesn't have a value, can you show use how the UserRating enumeration has been defined in DataTypeDictionary? For Browser to work correctly with custom enumeration, it must be defined in either the DataTypeDefinition Attribute of UserRating Node or in the DataTypeDictionary for the Namespace containing UserRating.

Does OPC UA Browser have support for "custom enumerations"? I am developing an OPC UA server where enumerations are needed and can't get them to work in OPC UA Browser. I have tried with UaExpert and there they work fine. The nodes also pass OPC UA Compliance Test Tool so I am quite confident there is nothing wrong with the implementation.

I tried enumerations with EnumValueType (EnumValue) and LocalizedText (EnumString) and could not get either one to work. Read returns an integer and write does not work at all, this is probably the worst issue as it makes the nodes not usable as I cannot select integer values either to write.

I was able to get "AxisScaleEnumeration" standard Enumeration to work (Write only but Read also just returns an integer), which is defined in the OPC UA standard: https://reference.opcfoundatio.....docs/5.6.7

I posted some screenshots here https://postimg.cc/gallery/d088gy9 regarding the issue.
