Does UaExport support websocket transport

Post by mreichert »

Hi,
does UaExpert support websocket transport (endpoint 'opc.wss')?
If not, is this planned in the near future?

Hi,

no, there are currently no plans to implement the Websocket transport in the UaExpert.

Same as for every single different transport bindings within OPC UA technology, they typically represent a certain use case. Typically only the applications that need to fullfil exactly this usecase are going to implement this certain transport. And if your application is a "web-application" it makes perfectly sense. The vast majority will implement and use the (mandatory) UA-TCP transport only. We of course know that this creates a (kind of) hen-egg problem, however the use case and it's market share will decide.

Ok, does any of your stacks (client or server) support this transport binding?

Hi,

no, our SDKs do not support the Websocket binding. However, with the layered architecture in our SDKs there is (theoretically) the ability to implement/integrate transport binding youself. Furthermore we don't know any implementation of others on the commercial SDK market.

We have lately added the PubSub protocol implementation including the UDP and in a second step MQTT transport binding for the PubSub.
