Control
HMI, through selector switch function block, but alternatively there can for example, be a physical
selector switch on the front of the panel which is connected to a binary to integer function block (B16I).
If the PSTO input is used, connected to the Local-Remote switch on the local HMI, the choice can also
be from the station HMI system, typically Hitachi Power grids Microscada through IEC 61850–8–1
communication.
The connection example for selection of the manual energizing mode is shown in figure 126. Selected
names are just examples but note that the symbol on the local HMI can only show the active position of
the virtual selector.

12.1.3 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.

function block.
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.
