Figure 301: Selection of the energizing direction from a local HMI symbol through a
selector switch function block.
15.1.3 Application examples
The synchronism check 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 analog inputs and to the function block
SESRSYN, 25. 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.
