7 FUNCTION
(3) Precautions
(a) 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 High Performance model QCPU.
If the "Allow" check box is not checked, a remote RESET operation is not
performed.
(b) Remote RESET cannot be performed when the High Performance model
QCPU is in RUN status.
(c) After the reset operation is complete, the High Performance model QCPU
will enter operation status set at the RUN/STOP switch.
1) With the RUN/STOP switch in the "STOP" position, the High
Performance model QCPU enters into the "STOP" status.
2) With the RUN/STOP switch in the "RUN" position, the High
Performance model QCPU enters into the "RUN" status.
(d) Take care that Remote RESET does not reset High Performance model
QCPU if an error occurs in the High Performance model QCPU due to
noise.
If Remote RESET does not reset, use the RESET/L.CLR switch to reset or
turn the PLC off.
POINT
(1) If Remote RESET is executed when the High Performance model QCPU is
stopped due to an error, the High Performance model QCPU enters the
operation status set at the RUN/STOP switch after it is reset.
(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 High Performance model QCPU is not reset since the reset
process is not performed in it.
If the status of the High Performance model QCPU 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.
