The PACSystems* RX3i CPU can be used to perform real time control

of machines, processes, and material handling systems. The CPU

communicates with the programmer and HMI devices via a serial

port using SNP Slave protocol. It communicates with I/O and smart

option modules over a dual backplane bus that provides:

▪ High-speed PCI backplane for fast throughput of new advanced I/O.

▪ Serial backplane for easy migration of existing Series 90*-30 I/O.

Features

▪ Contains 64 Mbytes of battery-backed user memory and

64 Mbytes of non-volatile flash user memory.

▪ Provides access to bulk memory via reference table %W.

▪ Configurable data and program memory.

▪ Programming in Ladder Diagram, Structured Text, Function

Block Diagram, and C. Refer to PACSystems RX7i & RX3i CPU

Programmer’s Reference Manual, GFK-2950.

▪ Supports auto-located Symbolic Variables that can use any

amount of user memory.
