This logic has the input-point "DEV01_CONTROL_REQ" for the reception of a select
command. That is, the input-point must be mapped for communication. The function will fail
to operate if mapping is not performed correctly. We will discuss how to map the input-points
for IEC61850 communication in section 4.1.7.
Output signal to BO
The DPSY01 function can issue an output signal "Selection success" at the output point
"DPSY01_OSL_BO_FLG", when the DPSY01 function determines that the "Remote-Closing-
Control" signal received is true. If the DPSY01 function determines that the "Remote-Closing-
Control" signal is not true, the DPSY01 function returns to the "Wait for a command" stage.
The user should note that the operation decision of the SYNDIF01 function is required
for the DPSY01 function; the operation decision is determined by the measurement of running
voltage and incoming voltage. Table 4.1-1 shows the relay-elements used in the SYNDIF01
function.
