1) Executing a subroutine program and interrupt program in a stand-by type program
After execution of the stand-by type program, the CPU module reexecutes the program that called a program
in the stand-by type program.
Figure 2.35 shows the operation when the subroutine and interrupt programs in the stand-by type program
are executed.
● For restrictions on programming of subroutine and interrupt programs, refer to the following.
• Subroutine program : Section 2.2.2
• Interrupt program : Section 2.2.3
● Use common pointers. ( Section 9.9.2)
If local pointers are used, subroutine programs in a stand-by type program cannot be executed from any other program.
