To keep it brief, we are developing HMIs using Ignition that often find themselves being run on wireless computers in areas with poor connection. Operators (understandably) frequently complain about long delays.
Is it possible to display the strength of the Perspective session to the gateway so I could put those diagnostics on the screen to see? It would help to us determine whether the issue was due to operator error or failure in our program, or highlight a need for better infrastructure.
Perspective is browser-based, and browser security models do not expose that kind of machine-specific information. Perspective scripts cannot help, because those run in the gateway.
(In a Vision client, you could call a local executable that interrogates the wifi interface to collect this information, and push it to the gateway for diagnostics.)
You could self-host an OpenSpeedTest server on the ignition gateway and then use an inline frame on a Perspective view to show the OpenSpeedTest client on the HMI. This would allow you to test the network connection between your gateway and the clients. You would have to click the start button to run the test, but it might get you what you need.
