Post by Lafond »

Hi

Is the new OPC UA Publish/Subscribe over AMQP support by C++ SDK, if not, when will it be?
Any example available?

Thanks

Hi,

The feature you are talking about is not released by OPC UA working group yet. Released SDKs support only features of released OPC UA specifications.
We do not expect a release of the specification before mid 2017.

We are doing some prototyping but we cannot give you any dates and or confirmations about availablity of AMQP support at this point in time.
Best regards

Hi

Thanks for the status clarification.
I heard that Unified Automation was deeply involved in the creation of prototype for the AMQP extension, that is why I was asking if things were "releasable" to get a filling of where things are going.

Waiting to see this update.

Hi Claude,

It is right that Unified Automation is deeply involved in the creation of prototypes for OPC UA PubSub. This is the new OPC UA Publish/Subscribe communication model extension that complements the existing OPC UA Client/Server communication model.

OPC UA PubSub has a concept for direct peer-to-peer communication using protocols as UDP and a broker based communication where a message broker is responsible for the message distribution and where standard messaging protocols like AMQP or MQTT are used by Publishers to send messages to the broker and Subscribers to receive messages from the broker.

The main interest of the OPC UA PubSub prototyping working group is in the UDP multicast option for peer-to-peer OPC UA PubSub communication. Therefore the current prototypes support only UDP multicast at the moment.

The OPC UA working group finished the PubSub release beginning of February 2018. The released specification will be published by the OPC Foundation soon.

We are currently in the process of finishing the update of our C++ SDK PubSub prototype to the released specification. This prototype is used in the OPC UA PubSub prototyping working group for the verification of the new OPC UA PubSub features.

The first official release of a PubSub module for the C++ SDK is planned for Q3 2018. Prio 1 is UDP.
We can currently not tell you jet if any broker based protocol will also be included in that release.
Best regards
