7.7.9 Setting method when multiple sequence programs are created

For the A0J2HCPU, some programs include main program and subprogram, and main programs have
SFC programs. When replacing those programs with the QCPU, they are separated into different
programs.
For the separated programs in the QCPU, the Program setting of the parameter setting is required.
This section provides precautions after replacement of program settings, etc.
(1) Program files at replacement
(a) When main program contains SFC program
For the A0J2HCPU, the SFC program operates as the microcomputer program of main program.
Since the QCPU deals the SFC program as one program, the SFC program is converted to "MAIN-
SFC". Accordingly, two separate programs are created when the ACPU is converted; "MAIN",
converted from main program, and "MAIN-SFC".
Register in the order of MAIN, MAIN-SFC in the Program setting of the parameter setting of GX
Developer, and set all execution types to "Scan".
Refer to Section 7.6 for precautions of replacing from the A0J2HCPU SFC (MELSAP-II) to the QCPU
(MELSAP3).
