Hello, We were discussing about developing an application for android and/or iphone, so an eHMI can be opened from there. Is there a way to open the eHMI from another network without VPN? Or is a VPN the most easy way to connect when your not in the same network? We have made a start with an app which actually just goes to the webpage of the HMI, but for now we should be in the same network. Do you maybe also have some recommendations for developing the eHMI with another program as the HMI webviewer in PLCNext Engineer, or is that the only way to make a HMI? Thanks in advance, Arne
Hello Arne,
If you want to access the ehmi without a VPN you will still need some kind of Gateway NAT or Port Forwarding.
But thats TCP/IP in general and not related specifically to the eHM.I believe before FW 2020.3 there were some issues with VPN/NAT and the eHMI in general.
You can use any html, JS… to build your HMI and use the REST API to access the variables.
These files can then be downloaded via the PLCnext Engineer as Support Files.kind regards,
Oliver
Is there an example about the support files? I have a html support file, but am not able to use those. I am not that good with html, so i would like to see an example.
