Figure 2.6-2 Sending DIFL operation signals for remote terminals
†Note: The DIFL#2 element is only available in the [TERM_TOPOLOGY]=2Term-Dual.
Figure 2.6-3 exemplifies the IEEE C37.94 frame format for sending the signals "DIFL-
A,-B, and -C"; the COM5-4, COM5-5, and COM5-6 bits are assigned. The communication
application function (COMM_APPL) function provides transmitting feature. Thus, we should
map the signals "DIFL-A, DIFL-B, and DIFL-C" to PLC connection points "COM5-4_S, COM5-
5_S, COM5-6_S"†.
