• Even though 'Request for saving/clearing parameters to Flash ROM' (Y17) is turned on while 'I/O
communicating' (X01) is on, 'Parameter save/clear completion to Flash ROM' (X07) does not turn on. Turn
off 'I/O communication request' (Y11) and turn off and on 'Request for saving/clearing parameters to Flash
ROM' (Y17) again after 'I/O communicating' (X01) turns off.
• Even though 'Request for saving/clearing parameters to Flash ROM' (Y17) is turned on while 'I/O
communication request' (Y11) or 'Auto configuration request' (Y15) is on, 'Parameter save/clear completion
to Flash ROM' (X07) does not turn on. Turn off the output signal, and turn off and on 'Request for saving/
clearing parameters to Flash ROM' (Y17) again.
• The parameter cannot be saved in the flash ROM in which a parameter error occurs. However, when either
of the master function or slave function is not used in master + slave function mode, all the parameters of
the unused function can be set to zero and saved.
• The number of writes to the flash ROM is limited. Therefore, execute 'Request for saving/clearing
parameters to Flash ROM' (Y17) only when creating a new parameter and changing the parameter.
'Module READY' (X0F)
This signal indicates whether the RJ71DN91 can operate or not.
This signal turns on when the RJ71DN91 becomes to be able to operate.
When 'Watchdog timer error' (X00) turns on, 'Module Ready' (X0F) turns off.
