Application examples

The synchronizing function block can also be used in some switchyard
arrangements, but with different parameter settings. Below are some examples of
how different arrangements are connected to the IED analogue inputs and to the
function block SESRSYN. One function block is used per circuit breaker.
The input used below in example are typical and can be changed by
use of configuration and signal matrix tools.
The SESRSYN and connected SMAI function block instances must
have the same cycle time in the application configuration.
