Other instructions
Sequence program stop (STOP)
When the stop input turns ON, the outputs Y are reset and the operation of the PLC is
stopped (the same function as when the RUN key switch on the CPU module is turned
to the STOP position). When the STOP instruction is executed, bit 8 of the special
register D9015 is set to 1. To resume operation of the PLC after execution of a STOP
instruction, move the RUN key switch to the STOP position, and then back to the RUN
position again. Do not use the STOP instruction in interrupt programs, subroutine or
FOFUNEXT loops, else an operation error occurs.
