Processing details
• Indicates termination of programs, including main routine program, subroutine program, and interrupt programs.
• Execution of the END instruction will cause the CPU module to terminate the program that was being executed.
• The END instruction cannot be used during the execution of the main sequence program. If it is necessary to perform END
processing during the execution of a program, use the FEND instruction.
• When programming in the ladder mode of a programming tool, it is not necessary to input the END instruction.
• The use of the END and FEND instructions is broken down as follows for main routine programs, subroutine programs, and
interrupt programs:
