Output signal to BO
The SPOS01 function, in Figure 4.1-4, can issue a "Select success" signal at the output point
"SPOS01_FSL_BO_CSF" when the SPOS01 function determines that the "Select command Off
(Remote-OFF-Control)" signal is true. If the SPOS01 function determines that the "Remote-
OFF-Control" signal is not true, the SPOS01 function returns to the "Wait for a command"
stage.

Figure 4.1-6 shows the select logic when a "Select command On (Local-ON-Control)" signal is
applied to the SPOS01 function. The signal is provided when an "On" key is pressed on the
IED front panel; the user is not required to map the signal from the IEC61850 communication.
Note that the user should set the scheme switch [SPOS01-CTRAHMI] to SBO when operation
from the IED front panel is required; we discuss how to set this in chapter
