POINT
(1) Even if Request for Saving Parameters to Flash ROM (Y17) is set to on while
I/O Communicating (X01) is on, Parameters Saved to Flash ROM (X07) is not
set to on. Set I/O Communication Request (Y11) to on, and after confirming
that I/O Communicating (X01) is off, set Request for Saving Parameters to
Flash ROM (Y17) to off and then on.
(2) Even if Request for Saving Parameters to Flash ROM (Y17) is set to on while
the following output signal is on, Parameters Saved to Flash ROM (X07) is not
set to on.
• I/O Communication Request (Y11)
• Auto Configuration Request (Y15)
Set the output signal to off, and then set Request for Saving Parameters to
Flash ROM (Y17) to off and then on.
(3) Since there is a restriction on the number of writes to Flash ROM, execute
Request for Saving Parameters to Flash ROM (Y17) only when parameters are
newly created or changed.
(7) Module Ready (X0F)

When the QJ71DN91 is ready to operate, it is set to on.
When Watchdog Timer Error (X00) turns on, this Module Ready (X0F) is set to
off.
