Three memory cassettes can be installed into the FX3U CPU, and when installed the memory cassette’s internal program is used in place of the internal RAM memory. The FX3U-FLROM-64L (stock no. 539-0853) features program transfer buttons to allow permanent overwriting of the RAM based-program. FX3U battery – this battery buffers the internal RAM memory of the FX3U in the event of a power supply failure. FX3U-USB-AW converts the USB interface to RS422 to allow direct programming of FX3U PLCs using a PC’s USB port with either GX Developer or GX IEC Developer programming software.
Fx3g-232-bd Mitsubishi plc rs232c communication board. The Mitsubishi interface adapter is designed to be used with the FX3G series. This interface adapter provides a second RS422 interface for the connection of an additional device to the controller. It is mostly used for RS232C communication. This sub-compact PLC offers extremely fast program execution, accepts up to eight special function modules and provides maximum flexibility and control power for a wide range of automation applications.
A programmable logic controller (PLC) is a small, modular solid state computer with customized instructions for performing a particular task. PLCs, which are used in industrial control systems (ICS) for a wide variety of industries, have largely replaced mechanical relays, drum sequencers and cam timers.
