Setting using a program
■Writing from the program
The Ethernet module monitors the pulse setting value in the buffer memory, and when a change is detected, the difference
from the previous pulse setting value is reflected in the current value.
The current value in the buffer memory can be rewritten using the program.

Present value -
Pulse setting value -
(1) After the programmable controller system is powered on or is reset, the Ethernet module clears the current value in the buffer memory and the pulse setting
value to 0, and turns on 'ModuleREADY' (Un\G34, b0).
(2) When it is necessary to restore the operating status before power-off or reset, the program writes the saved current value and pulse setting value when it
detects that 'ModuleREADY' (Un\G34, b0) is on.
(3) The program turns on 'BACnetStartupRequest' (Un\G37, b1).
(4) The Ethernet module turns on 'BACnetDuringStartup' (Un\G35, b1) and starts the integration count operation.
■Writing from a BACnet workstation or BACnet controllers
Present value
