Hello inrain;

Have you any experience on web servers?

The S7-1200 support a web server that you can connect to any company PC connected to the PLC from the company network, if you take care of the IP adresses properly; if the PLC is in a seperate subnetwork than the PC you will need a router.

See the following links for a basic understanding of how to use the S7-1200 web server and create html5 pages on the web client PC:

And here is one example of how you can take data from the web pages of the S7-1200 nd import it into Excel speadsheet:

Hello inrain;

It would be preferable to keep this discussion (and all of them) on the main forum page.

First, it would reach many other members in the forum who could be more knowledgeable than I am on specific subjects, which means that you could get more answers and hints.

Second, since we are all volunteering our experience and knowledge on the  forum, it would be easier to reach all members here rather than wait for a specific person to be available to answer when you need help.

Hope this helps,

Daniel Chartier
