The STOP (STOP) instruction terminates the execution of your program by causing a transition of the S7-200 CPU from RUN to STOP mode.If the STOP instruction is executed in an interrupt routine, the interrupt routine is terminated immediately, and all pending interrupts are ignored. Remaining actions in the scan cycle are completed, including execution of the main user program, and the transition from RUN to STOP mode is made at the end of the current scan.
