Operation principle
The Denial of service functions (DOSLAN1 and DOSFRNT) 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:
Description
Ethernet link status
Frame rate is higher than normal state
Frame rate is higher than throttle state
Values (Range) Unit
0=Off -
1=Normal
