4.1.2 Operation processing of RUN, STOP and PAUSE
The programmable controller CPU can be operated in the RUN, STOP and PAUSE as
described below.
Operation processing of programmable controller CPU in each operation status is
explained.
(1) Operation processing in RUN
(a) RUN status means that the sequence program operation is repeated as step 0
END (FEND) instruction 0.
(b) When entering the RUN status, outputs the stored output status at STOP
because of setting the output mode as STOP RUN in the parameters.
(c) Processing time from switching STOP RUN to the start of the sequence
program operation is usually one to three seconds, although it may vary
depending on the system configuration.
(2) Operation processing in STOP
(a) STOP status means that the sequence program operation is canceled due to the
RUN/STOP key switch, STOP instruction, or the remote STOP. (Refer to Section
4.3.)
(b) When entering the STOP status, stores the output status and sets all output
points to OFF. Data memories except for output (Y) are retained.
(3) Operation processing in PAUSE
(a) PAUSE status means that the sequence program operation is canceled retaining
output and data memories. (Refer to Section 4.3.)
