and monitoring application: Automatic sequence control function
*Note: The LEDR function can run on either "the SBO mode" or "the DIR mode" using a
"ctlmodel" signal when the communication is carried out in the IEC61850; thus,
mapping is required for the IEC61850 communication.
Output signal required mapping

The LEDR function can
"LEDR01_NSD_CSF", when the LEDR function determines that the input signal "Select
command (reset)" is true. If the LEDR function determines that the "LEDR01_NSD_CSF" is
not true, the LEDR function returns to the "Wait for a next command" stage.
