(4) Precautions
(a) Setting for remote RESET
To perform the remote RESET, check the "Allow" check box of the "Remote reset"
section at the "PLC system" tab screen in the "(PLC) Parameter" dialog box, and
then write parameters into CPU module.
If the "Allow" check box is not checked, a remote RESET operation is not
performed.
(b) Remote RESET in RUN status
Remote RESET cannot be performed when the CPU module is in RUN status.
Perform remote RESET after placing the CPU module in the STOP status by
performing remote STOP or similar operation.
(c) Status after reset processing completion
After the reset processing is complete, the CPU module will enter operation status
set by the RUN/STOP switch (RUN/STOP/RESET switch for the Basic model
QCPU and Universal model QCPU).
• With the RUN/ STOP switch (RUN/STOP/RESET switch for the Basic model
QCPU and Universal model QCPU) in the STOP position, the CPU module
enters into the STOP status.
• With the RUN/ STOP switch (RUN/STOP/RESET switch for the Basic model
QCPU and Universal model QCPU) in the RUN position, the CPU module
enters into the RUN status.
POINT
1. If remote RESET is performed with the CPU module stopping due to an error,
note that the CPU module is placed in the operation status set by the RUN/
STOP switch (RUN/STOP/RESET switch for the Basic model QCPU and
Universal model QCPU) upon completion of the reset processing.
2. Even if "Remote reset" is set as "Allow" at the "PLC system" tab screen in the
"(PLC) Parameter" dialog box, the remote process of the GX Developer is
completed.
However, the CPU module is not reset since the reset process is not
performed in it.
If the status of the CPU module does not change though a reset process is
performed from GX Developer, check if the "Remote reset" is set as "Allow" at
the "PLC System" tab screen in the "(PLC) Parameter" dialog box.
(d) When error occurs due to noise
Take care that Remote RESET does not reset CPU module if an error occurs in
the CPU module due to noise.
If Remote RESET does not rest, use the RESET/L.CLR switch (RUN/STOP/
RESET switch for the Basic model QCPU and Universal model QCPU) to reset or
turn the PLC off.
