Settings

The function does not have any parameters available in Local HMI or Protection
and Control IED Manager (PCM600)

Operation principle

Authority status (ATHSTAT) function informs about two events related to the IED
and the user authorization:
• the fact that at least one user has tried to log on wrongly into the IED and it
was blocked (the output USRBLKED)
• the fact that at least one user is logged on (the output LOGGEDON)
Whenever one of the two events occurs, the corresponding output (USRBLKED or
LOGGEDON) is activated.

Denial of service

Functionality

The Denial of service functions (DOSLAN1 and DOSFRNT) are designed to limit
overload on the IED produced by heavy Ethernet network traffic. The
communication facilities must not be allowed to compromise the primary
functionality of the device. All inbound network traffic will be quota controlled so
that too heavy network loads can be controlled. Heavy network load might for
instance be the result of malfunctioning equipment connected to the network.
