Operation principle
Summation block 3 phase 3PHSUM receives the three-phase signals from Signal
matrix for analog inputs function (SMAI). In the same way, the BLOCK input will
reset all the outputs of the function to 0.

Denial of service DOS
20.19.1
Functionality
The Denial of service functions (DOSFRNT, DOSLANAB and DOSLANCD) 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.
