(4) Precautions
(a) Remote RESET in the RUN status
When the CPU module is in the RUN status, the remote RESET operation cannot be performed.
To perform the operation, change the operating status of the CPU module to STOP by the remote STOP or
similar operation.
(b) Status after reset processing
After reset processing of the remote RESET operation is completed, the CPU module will be placed in the
operating status set by the RUN/STOP switch (the RUN/STOP/RESET switch for the Basic model QCPU).
If the switch is set to STOP, the CPU module will be in the STOP status. If the switch is set to RUN, the CPU
module will be in the RUN status.
●
If the remote RESET operation is performed to the CPU module which is stopped due to an error, note that the CPU
module will be placed in the operating status set by the RUN/STOP/RESET switch after reset processing is completed.
●
If the CPU module cannot be reset by the remote RESET operation from GX Developer, check that the "Allow"
checkbox for the remote RESET operation in the PLC system tab of the PLC parameter dialog box is selected.
If the checkbox is not selected, the CPU module cannot be reset even after the remote RESET processing from GX
Developer is completed.
(c) When an error occurs due to noise
Note that the CPU module may not be reset by the remote RESET operation from GX Developer.
In this case, reset the CPU module using the RUN/STOP switch (the RUN/STOP/RESET switch for the Basic
model QCPU) or power off and then on the CPU module.
