POINT
(1) Even if the save parameter to flash ROM request (Y17) is turned ON while the
I/O communicating (X01) is ON, save parameter to flash ROM completion
(X07) is not turned ON. Turn OFF the I/O communication request (Y11), then
after confirming that the I/O communicating (X01) is OFF, turn ON the save
parameter to flash ROM request (Y17) from the OFF state.
(2) Even if the I/O communication request (Y11) is turned ON while the save
parameter to flash ROM request (Y17) is ON, the I/O communicating (X01) is
not turned ON. Turn OFF the save parameter to flash ROM request (Y17), then
turn OFF the I/O communication request (Y11) once and turn it back ON again.
(8) Saving Parameter To Flash ROM: X06, Save Parameter To Flash
ROM Completion: X07, Save Parameter To Flash ROM Request:
Y17 (when the slave function is used)
These signals are used when saving the "setting area for the number of slave
function input points" and "setting area for the number of slave function output
points" 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 parameter in the "setting area of the number of slave function
reception bytes" and the "setting area of the number of slave function
transmission bytes" 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 number of I/O points check is successful, the number of I/O points
setting will be saved and the save parameter to flash ROM (X06) will turn
ON. If the number of I/O points check fails, the slave function for error set
signal (X08) is turned ON and the ERR. LED is lit. Check the contents of the
error in the "error information for the slave function" of the buffer memory
address 601
H
.
(c) When the number of I/O points setting is saved in the flash ROM, the save
parameter to flash ROM completion (X07) is automatically turned ON.
Communication with the master node is stopped while the number of I/O
points setting is being saved.
By turning OFF the request to save parameters to the flash ROM, the saving
parameters to the flash ROM complete is automatically turned OFF.
