We built an entire Vision HMI, and now at the end of the project, the customer says they need to access the SCADA via HTTP.
I told them this is the HMI, and while the HMI uses the SCADA tags to populate the display, their SCADA system would be the source for remote access.
NO, they want HTTP access to that display.
How can I do that?
Remote access would be determined by the HMI Hardware/OS and not the vision project itself. I have remote access to all of my Raspberry Pi HMIs with VNC. The VNC software runs as a service in the background on the Pi, then I use a VNC viewer program on my laptop to connect to it.
If the hardware is windows based, you should be able to use Remote Desktop (RDP).
