Browser requirements
Browser requirements
KMC Controls
Use only Microsoft Internet Explorer to view the web pages in a KMD-5270 controller. The browser requires the Java Virtual Machine, a product of Oracle, to view the trend graphs in the controller. Download the Java Virtual Machine at the following address.
www.oracle.com.
If you are using Internet Explorer version 10, which will only run on Windows 7 or Windows 8, you must enable the Compatibility View to get the WebLite web pages to work correctly. If you open the WebLite web page and the Login button is not present, change the compatibility mode by clicking the Compatibility icon in the address bar.
Click to change to compatibility mode.
Illustration 5-1 Changing to compatibility mode in IE 10.
Opening the
WebLite home page
To access a WebLite with a web browser, open a browser window and then enter the IP address for the controller in the address bar. The WebLite home page opens.
Note
Two IP addresses may be assigned to a WebLite. The network system administrator will provide the address.
