(7) Saving Parameter To Flash ROM: X06, Save Parameter To Flash
ROM Completion: X07, Save Parameter To Flash ROM Request:
Y17 (when the master function is used)
These signals are used to save the "parameters for the master function" of the
buffer memory to the flash ROM in the QJ71DN91. Make a request to save
parameters to the flash ROM while the I/O communicating (X01) is OFF.
(a) Set the parameters using the following steps:
1) Write the parameters in the "parameters for the master function" area of
the buffer memory.
2) Set the parameter save area selection bit.
3) Use the sequence program to turn ON the save parameter to flash
ROM request (Y17).
(b) When the request to save parameters to the flash ROM is accepted, and if the
parameter check is successful, the parameters will be saved and the saving
parameter to the flash ROM (X06) will turn ON. If the parameter check fails,
the master function for error set signal (X03) will turn ON and the ERR. LED
will light. Check the contents of the error in the "error information for the
master function" of the buffer memory address 1B1
H
.
(c) When the saving parameters to the flash ROM is completed, the save
parameter to flash ROM completion (X07) signal is automatically turned ON.
Communications with other slave nodes are stopped while the parameter is
being set.
By turning OFF the request to save parameters to the flash ROM, the saving
parameter to the flash ROM complete is automatically turned OFF.
