Figure 2.6-7 exemplifies the IEEE C37.94 frame format; we should map the SCOM4-SA0
bit for sending the signal “DIFGL”.

Reception of DIFGL-operation signal from the remote
Figure 2.6-8 shows the TFC reception logic; PLC connection point “R1.DIFGL_OP” is used for
the signal receiving from the Remote-1_IED, another PLC connection point “R2.DIFGL_OP”
is used from the Remote-2_IED.
