The IP address of the DNS Server used by your network. After 
entering the DNS Server’s IP address, you can input the 
device’s URL (e.g., http://ap1.weidmueller.com) in your

System Time 
The IE-WL-BL-AP-CL has a time calibration function based on information from an NTP server or user specified 
Date and Time information. Functions such as Logs and Notifications can add real-time information to the 
message. 
The Current local time shows the device’s system time when you open this web page. You can click on the Set 
Time button to activate the updated date and time parameters. An “(Updated)” string is displayed, which 
indicates that the change is complete. Local system time will be immediately activated in the system without 
running Save and Restart. 
NOTE 
The device has a built-in real-time clock (RTC). We strongly recommend that users update the Current local 
time for the device after the initial setup or a long-term shutdown, especially when the network does not have 
an Internet connection for accessing the NTP server or there is no NTP server on the LAN.
