Many thanks Amar,
I still have a problem identifying a suitable hardware for the local HMI touchscreen.
1. if I take your option "The Revolution Pi device can also be directly connected to HDMI based panel and the browser could access the WebVisu locally.", are you sure that the touch functionality will work with HDMI only ?
2. if I take your other option with a standalone screen with its OS and a browser, connected by ethernet directly to the RevPi, will this keep working safely in case of whole internet disruption ?
3. I couldn't find any hardware suggestions in the CODESYS HMI SL links, only a license ; on which kind of hardware can I install such license ?
Thank you for your support and time, sorry for bothering.
But I really need to have the ideas clear before purchasing the whole stuff...
