(7) Precautions
(a) Setting for remote RESET
(b) Before performing remote RESET
(c) Status after completion of resetting
(d) Remote RESET in the case of error stop
(e) Restarting after remote RESET
Before performing remote RESET, check the conditions described in (4) of this
section. Remote RESET is not allowed if the conditions in (4) are not satisfied.
Before performing remote RESET, close all user programs in the C Controller
module.
Performing remote RESET during operation of any user program may damage
the user program and data file. (
Execution of remote RESET changes the operation status of the reset C
Controller module or programmable controller CPU to the status set by the RUN/
STOP/MODE, RUN/STOP, or RUN/STOP/RESET switch.
1) When the RUN/STOP/MODE, RUN/STOP or RUN/STOP/RESET switch is set
to "STOP"
Upon completion of remote RESET, the operation status of the reset C
Controller module or programmable controller CPU changes to "STOP" status.
2) When the RUN/STOP/MODE, RUN/STOP or RNU/STOP/RESET switch is set
to "RUN"
Upon completion of remote RESET, the operation status of the reset C
Controller module or programmable controller CPU changes to "RUN" status.
If remote RESET is executed during a error stop of the C Controller module in a
single CPU system or CPU No.1 in a multiple CPU system, the status of the C
Controller module or programmable controller CPU is changed to the status set by
the RUN/STOP/MODE, RUN/STOP, or RUN/STOP/RESET switch. Therefore,
special attention must be paid.
When remote RESET is performed, the OS and system software of the C
Controller module will be restarted.
Note the following for each case.
1) When using bus interface function (QBF_Reset function)
There is no return value of the bus interface function (QBF_Reset function).
2) When using development environment (personal computer)
Remote RESET cuts off communication between the development
environment (personal computer) and C Controller module.
After remote RESET, reconnect the development environment (personal
computer) to the C Controller module.
