REPLACEMENT OF PROGRAM

7.7.10 Setting method when multiple sequence programs are created

For the AnSCPU, when a main program including SFC program is replaced for the QCPU, the programs
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 AnSCPU, 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 AnSCPU SFC (MELSAP-II) to the QCPU
(MELSAP3).
(2) Program setting of the GX Developer
The following explains required program settings for executing multiple programs.
The execution type of program is set in Program setting of the PLC parameter setting of GX Developer.
CPU module executes the programs of the specified execution type in the setting order.
