Note: The synchronism voltage check is executed by the SYNCHK function.

Note: A timer is provided to determine an operation failure. The maximum value of the

settings [SYNC01_TLRDIDRLI] or [SYNC01_TDRDI] is used as the decision time.

For more information on settings, see the SYNDIF function.

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 4.2.7.

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 4.2-2 shows the relay-elements used in the SYNDIF01
