M9012 (M9010, M9011)
Functions (1) When the stop input turns on, resets the outputs Y and stops the operation of
PC. (The same function as when the RUN key switch is moved to the STOP
position)
(2) When the STOP instruction is executed, b8 of the special register D9015 is set
to 1.
(3) To resume the operation of PC after the execution of STOP instruction, move
the RUN key switch from the RUN to the STOP position and then move it to the
RUN position again.
(4) Even if the RESET switch is moved to the “LATCH CLEAR” position when the
STOP instruction has been executed, latch clear is not executed. To execute the
latch clear, move the RUN key switch to the STOP position and then move the
RESET switch to the “LATCH CLEAR” position.
(5) Do not provide the STOP instruction in the interrupt program, subroutine
program, and FOR/NEXT. If the STOP instruction is provided, operation error
occurs.
