S7-1200: Webserver - using JSON to display PLC variables

"may one suggestion - did you tag the JSON in the device config as file with dynamic content?" -- oops, i did not undertand what do you mean.

Also, please, see the picture.

I understood, what you mean.

It starts working) Thank you a lot :)

just a simple piece of code for a webpage using AJAX and JSON
The example contains also the PLC Code as SCL sources.

be aware:
You need to add ".json" in the Device configuration / Webserver / User defined Webpages --> Files with dynamic content

Line 38

write( '""readWriteTag"=' + $("#writeTag").val() );

Should be

write( '"readWriteTag"=' + $("#writeTag").val() );

Bastian.Geier, Thank a lot for the example. 

The example has been very useful. 

 It would be missing to finish implementing the "array" part.

 Did you finally finish it?

Thanks in advance!!!

Bastian.Geier, Thank a lot for the example.

 It would be missing to finish implementing the "array" part.

var x = $('#string1').text().replace(/"|'|\s/g, "").split(";"); // read Textelement and Split data by semikolon into an array, remove qutations bevor split

$('#string11').text( x[0] );

$('#string12').text( x[1] );

$('#string13').text( x[2] );

$('#string14').text( x[3] );

 Did you finally finish it?

Thanks in advance!!!

 Hi

not sure where you have a problem, but the array part should be there :-)
So you need to descripe your problem more in detail
