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.

For a list of supported I/O, Communications, Motion, and Intelligent

modules, refer to the PACSystems RX3i System Manual,GFK-2314F or later.

▪ Supports up to 512 program blocks. Maximum block size is 128KB.

▪ CPU firmware may be upgraded in the field.

▪ CPU supports firmware upgrades of modules in its backplane.

▪ Two serial ports: an RS-485 serial port and an RS-232 serial port.

▪ Ethernet communications via the rack-based Ethernet Interface

module (IC695ETM001). For details on Ethernet capabilities, refer

to PACSystems RX7i & RX3i TCP/IP Ethernet Communications

User Manual, GFK-2224.

▪ Time Synchronization to SNTP Time Server on Ethernet network

when used with Ethernet Release 5.0 or later.

▪ Compliant with EU RoHS Directive 2002/95/EC using the following

exemptions identified in the Annex: 7(a), 7(c)-I, & 7(c)-III.
