Input point required mapping
Figure 3.5-6 shows the select logic when a "Select command Reset (Remote-Reset-Control)"
signal is applied to the GCNT01 function. The logic has an input-point "GCNT01_CMM_REQ"
for the reception of the select command. That is, 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 IEC61850 communication in Chapter 3.5.5.

"GCNT01_SLD_CSCN", when the GCNT01 function determines that the input signal
"Remote-Reset-Control" is true. If the GCNT01 function determines that the "Remote-Reset-
Control" is not true, the GCNTS01 function returns to the "Wait for a command" stage.
