(3) Precautions
(a) To perform the remote RESET, turn on the "Allow" check box of the
"Remote reset" section in the PLC System sheet of the PLC Parameter
dialog box, and then write parameters onto the Basic 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 Basic model QCPU is at the
RUN state.
(c) After the reset operation is complete, the Basic model QCPU will enter
operation state set at the RUN/STOP/RESET switch.
1) With the RUN/STOP/RESET switch in the "STOP" position, the Basic
model QCPU enters into the "STOP" status.
2) With the RUN/STOP/RESET switch in the "RUN" position, the Basic
model QCPU enters into the "RUN" status.
(d) Take care that Remote RESET does not reset Basic model QCPU if there is
an error in the Basic model QCPU due to noise.
If Remote RESET does not reset, use the RUN/STOP/RESET switch to
reset or turn the PLC off then on again.
POINT
(1) If Remote RESET is executed when the Basic model QCPU is stopped due to
an error, the Basic model QCPU enters the operation state set at the
RUN/STOP/RESET switch after it is reset.
(2) Even if the "Allow" check box of the "Remote reset" section in the PLC System
sheet of the PLC Parameter dialog box, the remote process of the GX
Developer is completed.
However, the reset process does not proceed in the Basic model QCPU and
therefore it is not reset.
If the state of the Basic model QCPU does not change though a reset process
is performed at the GX Developer, check if the "Allow" check box of the
"Remote reset" section in the PLC System sheet of the PLC Parameter dialog
box is turned on.
