The new FX3U series is the third generation of Mitsubishi Electric's successful compact PLC family. Developed for the international market, the new controllers feature a special second "adapter bus" system, which complements the existing system bus used for expansion, special function and network modules. Up to ten additional modules can be connected to this new adapter bus.
The FX3U controllers also impress with their speed (0.065us per logical instruction), a significantly larger instruction set with a total of 209 instructions and improved functions and modules, particularly for positioning tasks. Other improvements include enhanced communications capabilities with Ethernet, USB and RS-422 mini DIN connectors.
The enhanced networking support has also increased the I/O capacity of the new flagship model, which can now be expanded to a maximum of 384 I/Os, including networked connections.
