Method of execution of remote RESET
The following are the methods of execution of remote RESET.
Engineering tool method
Refer to the following.
GX Works3 Operating Manual
Method using external devices that use SLMP
Refer to the following.
MELSEC iQ-F FX5 User's Manual (SLMP)
When executing remote RESET, the settings that allow the remote reset of the CPU parameter must be
written to CPU module beforehand. In the case that they are not set, remote RESET will not be possible.
Precautions
Remote RESET in RUN status
When the CPU module is in RUN status, it cannot be reset by remote RESET. Change the CPU module to STOP status by
operations like remote STOP and then execute remote RESET.
State after completion of the reset process
When the reset process is completed on a CPU module on which remote RESET was executed, the CPU module will change
to an operation status set by the RUN/STOP/RESET switch. Setting the RUN/STOP/RESET switch to the STOP position, will
change the status to STOP and setting the switch to the RUN position will change the status to RUN.
Note that if a remote RESET is executed when the CPU module has stopped due to an error, the CPU
module will change to an operation status set by the RUN/STOP/RESET switch, by reset process
completion.
If status of CPU module does not change even after executing remote RESET by engineering tool, check
the remote reset settings in the CPU parameter. If it is not set, even after completion of the remote process
of engineering tool, reset process of the CPU module will not be carried out.
When an error occurs due to noise
When there an error due to noise, exercise caution as there is a possibility that PLC cannot be reset by remote RESET. When
reset by remote RESET is not possible, either execute reset by RUN/STOP/RESET switch or once again start up the power of
CPU module.
