Control
External selection of energizing direction
The energizing can be selected by use of the available logic function blocks. Below is an example
where the choice of mode is done from a symbol ,created in the Graphical Design Editor (GDE) tool
on the local 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 ABB Microscada through IEC 61850–8–1
communication.
The connection example for selection of the manual energizing mode is shown in figure 104.
Selected names are just examples but note that the symbol on the local HMI can only show the
active position of the virtual selector.

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.

switch 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.
