Mitsubishi FX-USB-AW RS-422 to USB Conversion Interface Unit for FX Series PLC

The Mitsubishi FX-USB-AW is designed to provide a convenient USB connection between a personal computer and compatible Mitsubishi Electric FX Series PLCs. By converting the PLC's RS-422 communication interface to USB, the adapter allows a modern computer with a USB port to communicate with supported FX Series controllers for programming and maintenance activities.

The interface supports several Mitsubishi FX Series PLC families and can work with Mitsubishi programming environments such as GX Works2 and GX Developer. The supported communication speed depends on the specific PLC model and version; for example, Mitsubishi specifies up to 115.2 kbps for FX3U and FX3UC, while other FX Series models have lower communication-speed limits. This makes it important to verify the PLC model before selecting the FX-USB-AW.

For industrial maintenance and legacy automation applications, the FX-USB-AW can be useful when connecting an existing Mitsubishi FX PLC to a USB-equipped computer. The unit includes status LEDs for power, sending, and receiving activity, and Mitsubishi specifies an approximate weight of 20 g. Mitsubishi currently lists the FX-USB-AW as scheduled for discontinuation, with an end-of-order date of March 2028 and a planned discontinuation date of September 2028, although availability may vary by region.
