3Theory 3.1Diagnostics via web server
The web server enables monitoring and administering of the CPU by authorized users over a network.
This permits evaluation and diagnostics over long distances. Monitoring and evaluation is possible without the TIA Portal; all you need is a web browser.
The web server is deactivated in the delivery state of the CPU. This means that you must load a project in which the web server is activated to enable access using the web browser.
The web server offers the following security functions:
- Access via secure "https" transmission protocol
- User authorization by means of a user list
- Restriction of access from certain interfaces
You need a web browser to access the HTML pages of the CPU.
The following web browsers have been tested for communication with the CPU:
- Internet Explorer (Version 8)
- Mozilla Firefox (Version 21)
- Mobile Safari (iOS5)

Note: Make sure that you protect the CPU from manipulation and unauthorized access through the use of different methods (e.g., limiting network access, using firewalls).
