Input signal generated at the local-end
Figure 4.8-8 shows the Select logic when a “Select command Off (Local-OFF-Control)” signal
is received is applied to the DPOS01 function. The signal is provided when the user presses
the “OFF” key on the IED front panel; the user is not required to map the signal from IEC61850
communication.
Output signal to BO
When the “select condition” signal is true, the DPOS01 function can issue a “Select success”
signal at the output-point “DPOS01_FSL_BO_FLG”.

Note: The signal “DPOS01_FSL_BO_FLG” is the same as the signal shown in Figure
4.8-4. If the signal “Local-OFF-Control” is not true, the DPOS01 function returns
to the “Wait for a command” stage.
