9 Web-based management WBM
The Web-based management interface integrated in the controller allows you to display
static and dynamic information from the controller from anywhere in the network via a web
browser (e.g., Internet Explorer 9).
The status and diagnostic functions are clearly displayed on a graphical user interface.
Every user with a network connection to the device has read access to that device via a
browser. A wide range of information about the device itself, set parameters, and the oper-
ating state can be viewed.
In Web-based management, you can manage the credentials of users who are permitted to
access the controller.
9.1 Requirements for the use of WBM
WBM via Ethernet As the web server operates using the Hyper Text Transfer Protocol, a web browser can be
used. Access is via URL “http://IP address of the device”. Example: “http://192.168.1.10”.
You can call WBM via every Ethernet interface of the RFC 4072S.
9.2 Establishing a connection to WBM
To establish a connection to WBM, proceed as follows:
• Open the web browser on your PC.
• In the address field, enter URL “http://IP address of the controller”
(example: “http://192.168.1.10”).
Initial access: TLS
certificate
The controller web server uses a self-signed TLS certificate automatically generated by the
controller for secure communication. Before the controller web server can be accessed, you
must authorize the TLS certificate in your web browser.
Calling Web-based management – Valid IP address required
WBM can only be called using a valid IP address. In the delivery state, IP address
“192.168.1.10” is preset for Ethernet interface LAN1.
Also refer to the information in Section “Web server” on page 174 when calling WBM.
If there is a PLCnext Engineer HMI application on the controller, entering URL “http://IP
address of the controller” calls the PLCnext Engineer application.
• To call WBM in this case, enter URL “http://IP address of the controller/wbm”.
