E-RT3 2.0 series of processors features a high-speed RISC processor, a choice of operating systems—VxWorks 6 or Linux—and complete compatibility with existing FA-M3 I/O platforms and CPUs. E-RT3 CPU can run proprietary algorithms or other specialized applications, while allowing the standard logic CPUs to coordinate discrete machine control. With the FA-M3 PAC family, a large selection of I/O modules including discrete, analog, temperature control module, motion or communication modules are available. Also, a mechanism is provided with which users can develop their own I/O modules.
