7.6.3 Specifications comparison between MELSAP-II and MELSAP3

A part of the specifications of SFC program (MELSAP3) are different from those of SFC program
(MELSAP-II). Therefore, when utilizing the SFC program (MELSAP-II) of A/AnSCPU as the SFC
program (MELSAP3) of QCPU, select the QCPU that meets the specifications of the existing SFC
program (MELSAP-II).
