7.6.3 Remote RESET
(1) What is Remote RESET?
(a) The remote RESET resets the High Performance model QCPU externally
when the High Performance model QCPU is at STOP status.
Even if the High Performance model QCPU RUN/STOP switch is at RUN,
the reset can be performed when the High Performance model QCPU is
stopped and an error that can be detected by the self-diagnosis function
occurs.
(b) Remote RESET can reset the High Performance model QCPU remotely
when an error occurs for which the High Performance model QCPU cannot
be operated directly.
Remote RESET can be executed only in STOP status. When the High
Performance model QCPU is in RUN status, use Remote STOP to arrange
the STOP status.
(2) Remote RESET Method
The remote RESET can only be performed from GX Developer or by operating
serial communication module.
To perform the remote RESET, follow the following steps:
(a) At the "PLC system" tab screen in the “(PLC) Parameter" dialog box, check
the "Allow" check box at the "Remote reset" section, and then write
parameters to the High Performance model QCPU.
