Operation principle
The Denial of service functions (DOSFRNT, DOSLANAB and DOSLANCD) measures
the IED load from communication and, if necessary, limit it for not jeopardizing the IEDs
control and protection functionality due to high CPU load. The function has the following
outputs:
•
LINKUP indicates the Ethernet link status
•
WARNING indicates that communication (frame rate) is higher than normal
•
ALARM indicates that the IED limits communication
