Hello,

our current idea is to publish OPC UA data as MQTT messages to the cloud. For the payload we want to use the UA binary format to reduce the network load.

Which tool / library could we use in the cloud (Azure) to decode/read the messages?

1) GZIP + JSON was left out of 1.05.03 by mistake. It will be added to 1.05.04. Have you looked at this option?

2) The BinaryDecoder/BinaryEncoder classes from the UA.NETStandard Stack can be used independently of UA services and can be used to build PubSub encoders/decoders in cloud environments that support .NET plugins.

3) OPCLabs has a general tool that can decode pub/sub messages but you will have to ask them for a link.

The OPC Labs library mentioned by Randy is QuickOPC, https://www.opclabs.com/produc…..ure/pubsub .

It is fairly complete for all kinds of OPC UA Subscriber development in .NET.

I will be happy to explain more, should you have questions.
