3.3.4 Stand-by type program
1) Operation of subroutine and interrupt programs in stand-by type
program
When the execution of the stand-by type program is finished, a program in the
stand-by type program is called and its execution is resumed.
Figure 3.40 shows the operation performed when the subroutine and interrupt
programs in the stand-by type program is executed.
CALL P100 instruction execution

POINT
1. Refer to the following section for restrictions on subroutine or interrupt
program creation.
• Subroutine program
• Interrupt program
2. Use common pointers.(
When local pointers are used, the subroutine programs in the stand-by type
program cannot be executed from another program.
(b) When changing execution type by instruction
Use the PSCAN, PLOW
execution type.Note23
Since the Redundant CPU and Universal model QCPU cannot use low speed execution type
programs, it cannot change the execution type using the PLOW instruction.
