Function
• Indicates the end of a normal scan program. (The execution of this instruction returns to the beginning of the program, and
a normal scan is executed.)
• This instruction is not required when there are no subroutine programs or interrupt scan programs.
• If there is a subroutine program or interrupting program, write this instruction at the end of the normal scan program.
• This instruction is used only once in a program. Do not use any startup conditions with this instruction.
Notes
• The END instruction is checked prior to the execution, and if there is an error, the following error codes are set in the special
internal output WRF001. Also, the CPU error code '34' is set to special internal output WRF000.
