Mitsubishi Electric MELSEC-Q Series - Specifications Comparison between MELSAP-II and MELSAP3; MELSAP3 Specifications Comparison between Qnascpu and QCPU

7 REPLACEMENT OF PROGRAM
7 - 33
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).
7.6.4 MELSAP3 specifications comparison between QnASCPU and QCPU
A part of the specifications of SFC program (MELSAP3) are different from those of SFC program
(MELSAP3). Therefore, when utilizing the SFC program (MELSAP3) of QnASCPU as the SFC program
(MELSAP3) of QCPU, select the QCPU that meets the specifications of the existing SFC program
(MELSAP3).
