Programming the PFC with WAGO-I/O-PRO CAA
3.1.7.3 Information on the web-based management system
In addition to the web pages already described in section 3, the following HTML pages are stored in your controller and provide information and configuration options. After opening the default page of your controller, you can access these pages via the hyperlinks in the left navigation bar of the browser window.
TCP/IP configuration
Under the TCP/IP link, you can view and change settings for the TCP/IP protocol, which is responsible for network transmission.
Snmp configuration
Under the Snmp link, you can view and change settings for the Simple Network Management Protocol, which is responsible for the transport of control data.

I/O Config
Under the I/O Config link, you can view the configuration of your fieldbus node.
Web security
Under the Web security link, you can setup read/write access rights by using passwords for different user groups in order to protect against configuration changes.
The following groups are provided for this:
User: admin; |
Pass word: wago |
User: guest; |
Pass word: guest |
User: user; |
Pass word: user |
Samples
Under the Samples link, a sample HTML page is provided, which you can use as a starting point to create your own web page. You can then store this or any other web page you have created into the file system of the controller using FTP download.
