S7webHMI

Siemens S7 built-in web-server based HMI framework.

This is a simple framework for smoothly reading and writing data from a Siemens S7-1200/1500 PLC.

Requires:

• Siemens S7 PLC w/ built-in web-server

Includes:

• jquery 3.0

Usage:

• index.html Modify as needed to customize the UI. As is: this app will pull and display data by name. Writing data takes a little more work.
• index.js You shouldn't need to edit this.
• data.json Edit your tags in here: the names are simply keys that you can use in your javascript; the values must be formatted specifically for the PLC to recognize them.
• write.html The submitting form in index.html needs to have the input elements named exactly as the PLC tag-names. Those exact same names need to be installed here.
