Configuration of fault monitoring of status changes on connections 
On this page, you configure whether or not an error message is triggered if there is a status 
change on a network connection.  
If connection monitoring is enabled, an error is signaled  
●  when there should be a link on a port and this is missing. 
●  or when there should not be a link on a port and a link is detected. 
If a fault occurs, the error LED lights up on the device. The currently pending error is 
displayed under "Information > Errors". 
In addition, the corresponding error message is entered in the result log table. The content of 
the event log table is displayed in "Information > Log Tables > Event Log".
