1.A wide range of optional interfaces are available to complement the
controller’s standard RS-422 port. You can install additional RS-232/422 or RS-485 active programming interfaces.Add-on RS-232 interfaces provide broad communications functionality and enable connection of serial peripherals like printers and barcode readers. An optional RS-485 interface can be used to configure a peer-to-peer network with up to eight PLC systems from the FX family.

2.Remote I/Os are supported both by the open AS-Interface and the MELSEC
I/O-Link networks. CC-Link, Profibus/DP and DeviceNet interfaces are also
available for the FX1N/FX2N controllers, enabling connection to a wide
variety of host controller systems.

3. With a cycle period of just 0.08µs per logical instruction it’s one of
the fastest PLC systems available in the range up to 256 I/Os.

a cycle period of just 0.08µs per logical instruction - время
(длительность?) цикла логической команды (на логическую команду?) всего 0,8 мкс.

4.A significantly enlarged instruction and device set makes the controller
even more effective and easier to use.

5. The standard 8,000 PLC program step internal memory with backup battery
can be expanded to 16,000 steps.
Стандартная внутренняя (оперативная?) память ПЛК на 8 000 программных шагов с резервной батареей может быть расширена до 16 000 шагов.
