The Basic model QCPU provides the RUN/STOP/RESET switches for switching
between the STOP status and the RUN status. The RUN/STOP/RESET switch also
provides the Reset and Latch Clear functions.
The Basic model QCPU performs self control of the operation status from an external
(GX Developer function, intelligent function module, and remote contact) source.
The following four options are available for remote operations:
• Remote RUN/STOP
• Remote PAUSE
• Remote RESET
• Remote LATCH CLEAR

The serial communication module is used as the example to describe the intelligent
function module.
(1) What is Remote RUN/STOP?
(a) The remote RUN/STOP performs RUN/STOP of the Basic model QCPU
from an external source with the Basic model QCPU RUN/STOP/RESET
switch at RUN.
(b) Using remote RUN/STOP for the following remote operations are useful:
1) When the Basic model QCPU is at a position out of reach
2) When performing RUN/STOP of the control board Basic model QCPU
from an external source
(c) Calculations during Remote RUN/STOP
The program calculation that performs remote RUN/STOP is as follows:
1) Remote STOP
Executes the program to the END instruction and enters the STOP
state.
2) Remote RUN
When remote RUN is performed while in the STOP state using remote
STOP, the state changes to RUN and executes the program from
step 0.
