If the initial setting data are written using a sequence program, the initial
setting values are written when the PLC CPU is changed from STOP to RUN
status. Therefore, perform programming so that the initial setting will be reexecuted with the sequence program.
The parameter setting by sequence program has priority over the parameter
setting by the initial setting when both of them are used.

The initial settings are stored as the intelligent function module parameters.
After the intelligent function module parameters have been written to the PLC
CPU, the initial setting is updated when the PLC is powered ON from OFF or
the PLC CPU is reset (with the PLC CPU's RUN/STOP switch set to RUN).
If the QJ71MB91 is mounted on a MELSECNET/H remote I/O station, the
initial settings become effective when the remote I/O station receives the
information notifying the status change (from STOP to RUN) of the remote
master station's PLC CPU.
