For flash ROM (X06), (X07), (Y17)
Use 'Parameter saving/clearing to Flash ROM' (X06), 'Parameter save/clear completion to Flash ROM' (X07), and 'Request
for saving/clearing parameters to Flash ROM' (Y17) for saving the parameter of the buffer memory to the flash ROM of the
RJ71DN91 or clearing parameters saved in the flash ROM.
These areas are set whether to save the parameter of the buffer memory to the flash ROM or clear the parameter saved in the
flash ROM by 'Parameter save/clear selection bit' (Un\G1584). ( Page 93 Parameter save/Clear selection area)
■When saving the parameter of the buffer memory to the flash ROM
• Execute when 'I/O communicating' (X01) is off.
• Set saving parameters (0000H) to 'Parameter save/clear selection bit' (Un\G1584).
• When 'Request for saving/clearing parameters to Flash ROM' (Y17) is turned on, the parameter is checked.
• When the parameter check normally completes, the parameter saving to the flash ROM starts and 'Parameter saving/
clearing to Flash ROM' (X06) turns ON.
• When the parameter check abnormally completes, the ERR LED turns on and 'Master function error set signal' (X03) or
'Slave function error set signal' (X08) turns on. For details, refer to the following.

Page 69 For slave function error (X08), (Y18)
• When the parameter saving to the flash ROM completes, 'Parameter save/clear completion to Flash ROM' (X07) turns on.
• When 'Request for saving/clearing parameters to Flash ROM' (Y17) is turned off, 'Parameter saving/clearing to Flash ROM'
(X06) and 'Parameter save/clear completion to Flash ROM' (X07) also turn off.
