■ BCD DATA (32-bit data, models: R3-BA32A, BC32A, etc.)
32-bit binary data is used for BCD.
Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.
32-bit data cannot be accessed using floating addresses.

■ MAIN / SUB SWITCHING CONTROL
R3 main network
(main/sub switching control)
Address : 01025 = 1
Address : 01025 = 0
Communication Status
R3 sub network
(main/sub switching control)
Address : 01025 = 1
Address : 01025 = 0
1) When the main/sub switching control for both main and sub network is set to '0,' all contact outputs are off, and analog
output modules output -15%.
2) When the main's setting is switched to '1,' the output modules are in control of the main host device.
3) When a loss of communication is detected in the main network, the output signal is held for the preset time period. (Timer
is programmable with the PC Configurator Software, R3CON.) After the time has been elapsed, the output control is
switched from the main to the sub network. Be sure to set an appropriate output signal to the sub network and switch the
sub's setting to '1' before such switching occurs.
4) The output modules' control does not automatically switched back to the main's when the main network is restored if the
main's setting is '0.' Be sure to switch the setting back to '1' before the communication is restored.
5) When both the main and the sub network modules are in communication, the output can be switched without delay.
