Our company is developing a website show a summary of operation values and they need some process values from wincc system. developers are asking me to provide a URL which by calling them they could access process value. what is the best solution for this subject?

Thank you

hello murof

thanks for your help. i dont have rest in my runtime setup. my wincc version is 7.4 sp1 update 4.

is there any special version for rest or update?

thank you

The easiest way will be, to create a global script triggered for example every 10 seconds, that writes a static html site, with the relevant tag values inserted. Then setup a webserver that hosts this html file.

If you need more than one html site, you can for example export all process values in WinCC to a json file, and load the relevant tags from within a html file.

For just showing values, it's in my opinion the easiest way, which works with every WinCC version without any additional costs.

 You just write a file with the correct format for html or json. For example a simple html:
