4.8 Web-Based Management - WBM
4.8.1 Overview and First Steps
(1) Accessing WBM
• The CPU has a web-based management (WBM). In the WBM you can access static and dynamic information
and change certain settings. You may access WBM via the Ethernet interfaces of the CPU.
• The communication between the PC and CPU takes place via a security certificate, which must be located on
the CPU and PC.
• You may only access WBM if the CPU has a valid IP address.
• In the delivery state, the CPU has the IP address 192.168.1.1 via Ethernet port (X3/X4).
1. For the initial commissioning, establish a secure connection between the PC and CPU,
such as a point-to-point connection via Ethernet.
2. Open the web browser on your PC.
3. You can use the iCube Engineer search to determine the IP address of the correspond-
ing Ethernet interface.
Enter the URL in the address field such as https://192.168.1.1
For secure communication the CPU web server uses a self-signed TLS certificate that is automatically
generated by the CPU during the commissioning. Due to the system, you will receive a security mes-
sage regarding the certificate, as it has not yet been installed on the PC. After logging in, you can install
the corresponding certificate from the CPU as a trusted certificate on your PC (see below). This authen-
ticates the CPU to the web browser on the PC.
4. Take note of the security message and only continue if there is a secure connection
between the PC and CPU and no third parties can access it!
The WBM login page opens.
5. Enter your login details and click on [Login].
On delivery, the following access data are preset with administrator rights:
• Username: admin
• The password is printed under the front flap on the front of the CPU.
You now have access to the WBM of the CPU with the access rights assigned to you.
(2) Install Certificate
First access via TLS certificate
•
During commissioning, the CPU generates a TLS certificate during the start-up.
•
The certificate is used for all Ethernet interfaces of the CPU and includes all IP addresses.
•
When resetting to factory settings, a new certificate is automatically generated.
To secure communication, the same security certificate must be installed in the PC and CPU. You transfer the
