Hello,
could someone please provide examples how to encode OPC UA Built-In types to JSON for further processing? Assuming that it should be possible, as it specified in OPC 10000-6, OPC Unified Architectur, Part 6: Mappings.
Thank you in advance

Hi,
We do not support that yet. It is a relatively new thing, as it was only added in 1.04.
We will eventually release a “JsonEncoder” as it is needed for PubSub support that we are currently working on.

Hello,
I’d like to come back to this very old topic because I think a lot has happened since then. I’m using version 5.2 of the Prosys OPC UA SDK, which now includes the announced JsonEncoder/JsonDecoder. I now have a similar task: the value from a node should be read and converted to JSON. In my case, the value is of the data type Structure or Structure[]. The best solution would be as generic as possible, one that can convert virtually any value from a node to JSON. I think this is a question you’re familiar with. Unfortunately, I haven’t found any documentation on JsonEncoder other than javadoc, but it’s not very comprehensive. Am I even on the right track with JsonEncoder? Do you have any other documentation/examples that I just haven’t found?
Thank you for any advice
Michael
