I have come a little distance into my sbRIO system with a handful of actors for measurement, control and application.The system will only have a Machine-Machine Interface, specifically a SCPI protocoll, transported over serial or or TCP.And such a structured protocoll, translates pretty well into Message Objects (it would be nice if either our GDS tool or NIs Message Maker had a specific API for creating mesasge classes from XML).Up until now I have been using the Linked Network Actor method shown in the AF-cRIO example. And I am really pleased with its robustness, whenever I get it to work, its hard to break.But, of course there is a but, I've spent a lot of time troubleshooting the setup, getting it to work, keeping it working as the app grows, seeing to it that the right messages are sent across the net and so on. I am now considering a Web Service interface, and when doing so, have one basic question:In my Web Service VIs (running in the web server App instance), whats the best way to send messages to / get messages from my Interface Actor ?What i'm going to try first is using VI-server to call a repository VI in the .rtexe which holds the message-enqueuer/message-dequeuer refs. and in the same way run the Send methods for the specific messages.Whatd'ya think?/Marcus

Reviving this thread...

Hi everyone,

With all the advancements in LabVIEW after these years, what is being the best approach for communicating with web services in AF.
I've read many discussions in forums, and something pointed me towards using Reply Message, but somehow I would need to pass the enqueuers. For this reason, I am not entirely sure about using it.

What are you guys using?

Regards,

Felipe Pinheiro Silva
