Table 4.2-10.
Output signal to BO
The DPSY01 function, in Figure 4.2-4, can issue a “Select success” signal at the output point
“DPSY01_FSL_BO_FLG” when the DPSY01 function determines that the “Selection command
Open (Remote-Open-Control)” signal is true. If the DPSY01 function determines that the
“Remote-Open-Control” signal is not true, the DPSY01 function returns to the “Wait for a
command” stage.

Input signal generated at the local-end
Figure 4.2-6 shows the select logic when a “Select command Closing (Local-Closing-Control)”
signal is applied to the DPSY01 function. The signal is provided when a “Selection for Closing”
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 [DPSY01-
CTRAHMI] to SBO when operation from the IED front panel is required, we discuss how to set
this in chapter
