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.
