Issue Details

I am using a Linux Real-Time (RT) target and am trying to communicate between my RT VI and my Web Service. I have been trying to use named Queues and RT FIFOs but they don't seem to work. How do I communicate between these?

Solution

Your Web Service will act as a Human Machine Interface (HMI) and therefore to communicate between your web service and your RT VI you will need to use HMI to RT communication such as Network Streams or Network-Published Shared Variables.
