Select logic for resetting LEDs
3.4.1
The user should set scheme switch [LEDDR1] to On prior to the LEDR operation. Figure 3.4-1
shows selection logic in the LEDR function.

Figure 3.4-2 shows the select logic when a "Select command (reset)" signal is applied to the
LEDR function. The logic has an input-point "LEDR01_CONTROL_REQ" for the reception;
the input-point must be mapped for IEC61850 communication. The function will fail to operate
if mapping is not performed correctly. We will discuss how to map the input points for the
IEC61850 communication in Chapter 3.4.5.

‡Note: A "select condition" signal is provided from the select condition scheme. For more
information, see Figure 3.4-8.
*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.
