Hello,
I'd like to have access to the input variables of my running webvisu.htm visualisation in order to manipulate them with another method rather than using mouse and keyboard. I thing that the WebVisu.html code could be useful. I copied it into different places in the folder structure of Raspbian close to the webcvisu.htm generated by codesys. However, I can see only an empty window, when I start it.
Here is the folder loaction where both files are stored. Only from there I can start them both in a browser:
/root/PlcLogic/visu

the browser address lookm like this:
my_IP:8080/webvisu.htm => original codesys generated stand-alone visualisation is running
my_IP:8080/WebVisu.html => empty window with header "r47"

Looking at the page source network connection of the WebVisu.html it shows the different URLS are demanded but can't be found.

Anyone has got a hint?

What I originally wanted to do:
My goal is to read the input variables out of a parameter file into my stand-alone application that controls an Ethernet/IP device. Maybe CodeSys provides this function already, but I'm new to it and don't know it very well yet. The values of the input variables are modified by another application, that communicates with a measurement network and a forecast database.

Greetings and have a nice weekend!
Oliver
