Remote RESET is a function for resetting the QnACPU by operation from an external

to the RUN position if the CPU module is stopped by an error detectable by the self-
diagnostics function.

Application of remote RESET
Remote RESET can be used to reset the CPU module by remote operation when an
error has occurred in the place from where the CPU module cannot be directly
operated.
Methods for remote RESET
Remote RESETcan only be performed by operation from GPP function or a serial
communication module.
(a) Regardless of whether reset is performed from GPP function or a serial
communication module, the setting to enable remote RESET has to be made in
the Parameter before performing the reset operation.
The remote RESET "Enable/Disable" setting is made in the PLC system in the
parameter mode of GPP function.
(b) When the parameter is set to "Allow" in the "Remote reset" and written to the
CPU module, resetting is performed with remote operation.
• When using GPP function, perform the reset in the PLC menu in any mode.
• When using a serial communication module, perform the reset with dedicated
protocol commands.
For details on serial communication module control, refer to the Serial
Communication Module User's Manual.
