The RX3i control system hardware consists of an RX3i universal backplane and up to seven
Series 90-30 expansion or remote racks. The CPU can be in any slot in the universal backplane
except the last slot, which is reserved for the serial bus transmitter, IC695LRE001.
The RX3i supports user defined Function Blocks (LD logic only) and Structured Text programming.
The RX3i universal backplane uses a dual bus that provides both:
▪ High-speed PCI for fast throughput of new advanced I/O.
▪ Serial backplane for easy migration of existing Series 90-30 I/O
The RX3i universal backplane and Series 90-30 expansion/remote racks support the Series 90-30
Genius Bus Controller and Motion Control modules, and most Series 90-30/RX3i discrete and analog
I/O with catalog prefixes IC693 and IC694. RX3i modules with catalog prefixes IC695, including the
Ethernet and other communications modules can only be installed in the universal backplane. See
the PACSystems RX3i System Manual, GFK-2314 for a list of supported modules.
RX3i supports hot standby (HSB) CPU redundancy, which allows a critical application or process to
continue operating if a failure occurs in any single component. A CPU redundancy system consists of
an active unit that actively controls the process and a backup unit that is synchronized with the
active unit and can take over the process if it becomes necessary. Each unit must have a redundancy
CPU, (IC695CRU320). The redundancy communication path is provided by IC695RMX128 Redundancy
Memory Xchange (RMX) modules set up as redundancy links. For details on the operation of
PACSystems redundancy systems, refer to the PACSystems Hot Standby CPU Redundancy User
Manual, GFK-2308.
RX3i communications features include:
▪ Open communications support includes Ethernet, PROFIBUS, PROFINET, Modbus TCP, Ethernet
Global Data (EGD), DNP3 and serial protocols.
▪ On the CPE400 one of its embedded Ethernet ports is set up as a dedicated Field Agent port.
▪ The CPE305, CPE310, and CPE330 and CPE400 CPUs provide an embedded Ethernet interface
which is used to connect to the programmer (Proficy Machine Edition).
▪ Effective with RX3i CPE310/CPE305 Firmware Release 7.30, or CPE330 Firmware Release 8.50, the
embedded Ethernet port on the CPU provides support for Service Request Transfer Protocol
(SRTP) channels and for Modbus TCP. This feature is available on all firmware releases of CPE400.
▪ Effective with CPE310/CPE305 Firmware Release 8.20, or CPE330 Firmware Release 8.45, the CPE
embedded Ethernet port supports OPC UA Server. This feature is available on all firmware
releases of CPE400. Refer to PACSystems RX7i & RX3i TCP/IP Ethernet Communications User
Manual, GFK-2224 version M or higher (Chapter 10).
▪ Effective with RX3i Firmware Release 8.302
, the CPE310/CPE305 CPUs also support Ethernet
Global Data (EGD). Prior to that firmware release, EGD was only available in the RX3i via the RX3i
Ethernet Interface Module (IC695ETM001). With this upgrade, these CPUs are positioned as a
direct replacement for S90-30 IC693CPU374
