Instruction Behavior
The STOP instruction behaves as follows:
- When the execution condition of the STOP instruction is powered ON (1), the STOP instruction resets the output, Y, and stops the PLC process.
- To restart the PLC process, change the RUN/STOP key switch from RUN→STOP→RUN.
- The STOP instruction should not be located in an Interrupt Program, Subroutine Program, or the FOR ~ NEXT instructions.
- If the STOP instruction is executed, it operates the same as changing the RUN/STOP key switch from RUN to STOP.
Operation Behavior
Operation of the STOP instruction according to the PLC:
- When the STOP instruction is operated with the CPU type such as BP, XPnA1R, CP3/A/B/P/U, and P4A~D/U:
- All scan programs are executed and then the CPU mode changes.
- When the STOP instruction is operated with the CPU type such as PLC-S, XPnB/E/F, and CPnE/F:
- The scan program that includes the STOP instruction is executed until the END instruction and then the CPU mode changes, and no other scan programs are executed.
