FUNCTIONS
6.6.3 Remote RESET
(1) Definition of Remote RESET
The remote RESET resets the CPU module externally when the CPU module is in
STOP status.
Even if RUN/STOP switch (RUN/STOP/RESET switch for the Basic model QCPU and
Universal model QCPU) is in RUN, the reset can be performed when the CPU module
is stopped and an error that can be detected by the self-diagnosis function occurs.
(2) Applications of remote RESET
Remote RESET allows the faulty CPU module in a remote location to be reset by
remote operation.
(3) Remote RESET method
Remote RESET operation can be performed by only GX Developer or external device
using MC protocol.
To perform the remote RESET, follow the following steps:
• 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
CPU module.
• When the CPU module is in RUN status, use remote STOP to arrange the STOP
status.
• Reset CPU module by the remote RESET operation.
For the GX Developer, this is performed by [Online] [Remote operation.]
The serial communication module and Ethernet interface module are controlled
by commands complying with the MC protocol.
