AB 5/05 WebserverThe New Firmware For the AB 5/05 Is supposed to allow ME to write Custom HTML Pages For the Built in webserver And then Upload them with Linx onto the Processor. Now What are the Parameters to Allow me to Manipulate the Data thru a web Page, Change Values Etc.?
Please help.
Please help.
I found that with the custom Web pages you are only allowed to view the data.
This was about six months ago, I haven't heard any new news that would make me believe things had changed yet.
You can use the following command to display data on your page: <!ABDTR-F38:0,1>
Graphics must be stored on a PC and called from there.
Good Luck; I hope more features will be added to this technology.

The implementation instructions for the embedded web server as it now exists in Series C FRN 6 or newer SLC 5/05 processors are in Appendix E of the User Manual, at
http://www.ab.com/manuals/cp/1747-um011d-en-p.pdf
While you can create complex web pages with external content and live animation, the processor remains Read Only from your standard browser. You cannot change data table values as of today via the web server. (You could
always do this from a browser with RSLinx Pro or RSLinx Single Node.)
Hope this helps!

The way that I would solve that problem is with a different approach. That built in web server is clunky and weak at best at this point.
FactorySQL is a program that runs as a windows service that will bi-directionally tie your SLC to any SQL database (via Linx).

Once the data is in a standard database, it's simply a matter of making web pages however you want. PHP, ASP, Cold Fusion, JSP, etc all work fine with SQL databases. You could display values, OR write values down to the PLC by writing to the appropriate place in the database.
To take things a bit further, Inductive Automation offers a full featured web based HMI that runs on the same platform.
