STOP
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.
