(1) What is Remote RESET?
(a)
The remote RESET resets the Basic model QCPU from an external source
when the Basic model QCPU is at STOP state.
Even if the Basic model QCPU RUN/STOP key switch is at RUN, the reset
can be performed when the Basic model QCPU is stopped and an error that
can be detected by the self-diagnosis function occurs.
(b)
Remote RESET can reset the Basic model QCPU remotely when an error
occurs for which the Basic model QCPU cannot be operated directly.
Remote RESET can be executed only at the STOP state. When the Basic
model QCPU is at RUN state, use Remote STOP to arrange the STOP
state.
(2) Remote RESET Method
The remote RESET can only be performed from the GX Developer function or
serial communication module operation.
To perform the remote RESET, follow the following steps:
(a)
In the PLC System sheet of the PLC Parameter dialog box, turn on the
"Allow" check box in the "Remote reset" section, and then write parameters
onto the Basic model QCPU.
(b) When the Basic model QCPU is at RUN state, use remote STOP to arrange
the STOP state.
(c)
Reset Basic model QCPU with the remote RESET operation.
1) For the GX Developer function, this is performed in on-line remote
operation.
2) The serial communication module and Ethernet interface module are
controlled by commands complying with the MC protocol.
For details of the MC protocol, refer to the following manual.
