(2) Initial setting by remote device station initialization procedure
registration
(a) Setting the target station number
Set the station number to which initial setting will be made.
Set the target station number to "1".
(b) Setting the procedure registration
When the initial data processing request flag (RX18) turns on and the
remote device station initialization procedure registration (SB0D) is set, the
following data are registered to the AJ65VBTCU-68DAVN.

Initial data processing completion flag (RY18) is turned on.
Initial data processing request flag (RX18) turns on
Initial data setting request flag (RY19) is turned on.
Initial data processing request flag (RX18) turns off
Initial data processing completion flag (RY18) is turned off.
Initial data setting completion flag (RX19) turns on
Initial data setting request flag (RY19) is turned off.
(c) Setting results
The setting results are shown below.
POINT
(1) If the remote device station initialization procedure registration directive
(SB000D) is turned off after the initial processing, all RY signals that were
turned on within the initial procedure registration turn off. Hence, turn on the
"CH. analog output enable/disable flag (RYn0 to RYn7)" in the sequence
program.
(2) When the initial setting (analog output enable/disable setting (RWwm+8), CH.
output range setting (RWwm+9, RWwm+A) or HOLD/CLEAR setting
(RWwm+B) has been changed, the remote device station initialization
procedure registration function cannot be used.
Change the initial setting in the sequence program.
(3) For the case where the remote device station initialization procedure
registration function is not used but a sequence program is used to make
setting, refer to the user's manual of the used master module.
