1.5 Program Execution Type

Standby type program
This type of program is executed only when its execution is requested.
Librarization of programs
Set a subroutine program and/or an interrupt program as a standby type program to manage them separately from the main
routine program. In a single standby type program, multiple subroutine programs and interrupt programs can be created.
Program arrangement change
Prepare programs available in all systems to use them only when necessary. For example, a program set in advance as the
standby type with a parameter can be changed to scan execution type and executed. ( Page 64 Using an instruction)
Execution method
The standby type program is executed as follows.
• Create a subroutine program and interrupt program within the standby type program, and then call them when an interrupt
occurs or by specifying with a pointer.
• Switch to another execution type program.
