Hello dear community

I would like to ask how it is posscible to implement the pubsub model bettwen the embedded WinCC 7.4 UA server V1.0  and a UA Client.

The task is just to publisch online data for a client. (Acron software from Videc) It is written that existing UA protocol already includes a subscription model that allows the server to publish notifications of data changes. 

 

what could be a solution since both software are complete and certified. There is an UADP multicast approach but how to configure the server at least?

 

thank you in advance

best regards

Igor

PubSub requires products to explicitly support and products in the field generally do not support it yet.

You can build a gateway that add PubSub to existing applications, however, this requires software development work.
