1.3.3 Ethernet Global DataNote: Effective with RX3i CPE310/CPE305 Firmware Release 8.30, the CPU itself also supports EGD
Class 12. Prior to that firmware release, EGD was only available in the RX3i via the RX3i
Ethernet Interface Module (ETM001).
Each PACSystems CPU supports up to 255 simultaneous EGD pages across all Ethernet interfaces in
the Controller. EGD pages must be configured in the programming software and stored into the CPU.
The EGD configuration can also be loaded from the CPU into the programming software. Both
produced and consumed pages can be configured. PACSystems CPUs support the use of only part of
a consumed EGD page, and EGD page production and consumption to the broadcast IP address of
the local subnet.
The PACSystems CPU supports 2ms EGD page production and timeout resolution. EGD pages can be
configured for a production period of 0, indicating the page is to be produced every output scan. The
minimum period for these “as fast as possible” pages is 2ms. Refer to the section, A3.6 for EGD
configuration on Embedded Ethernet interface of CPE305/310.
During EGD configuration, PACSystems Ethernet interfaces are identified by their Rack/Slot location.
1.3.4 OPC UA
Each PACSystems CPE305/CPE310 supports Open Productivity and Connectivity Unified Architecture
(OPC UA) Server communications on the embedded Ethernet port only.
For more information on OPC UA support see GFK-2224 version M or higher (Chapter 10).
Note: Effective with CPE310/CPE305 Firmware Release 8.20, the CPE embedded Ethernet port
supports OPC UA Server.

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’s
Guide, GFK-2308.
RX3i communications features include:
■ Open communications support includes Ethernet, PROFIBUS, PROFINET, Modbus TCP, Ethernet
Global Data (EGD), DNP3 and serial protocols.
■ The CPE305 and CPE310 CPUs provide an embedded Ethernet interface which is used to connect
up the programmer (Proficy Machine Edition).
■ Effective with RX3i CPE310/CPE305 Firmware Release 7.30, the embedded Ethernet port on the
CPU provided support for Service Request Transfer Protocol (SRTP) channels and for Modbus TCP.
■ Effective with CPE310/CPE305 Firmware Release 8.20, the CPE embedded Ethernet port supports
OPC UA Server. See GFK-2224 version M or higher (Chapter 10).
■ Effective with RX3i CPE310/CPE305 Firmware Release 8.30, the CPU itself also supports Ethernet
Global Data (EGD) 2. Prior to that firmware release, EGD was only available in the RX3i via the RX3i
Ethernet Interface Module (ETM001). With this upgrade, these CPUs are positioned as a direct
replacement for S90-30 IC693CPU374.
■ The rack-based ETM001 Ethernet Interface has dual RJ-45 ports connected through an autosensing switch.
This eliminates the need for rack-to-rack switches or hubs. The ETM001 supports
upload, download and online monitoring, and provides 32 SRTP channels with a maximum of 48
simultaneous SRTP server connections. It also supports Modbus TCP. For details on Ethernet
Interface capabilities, refer to TCP/IP Ethernet Communications for PACSystems, GFK-2224.
■ PROFIBUS communications via the PROFIBUS Master module. For details, refer to the PACSystems
RX3i PROFIBUS Modules User’s Manual, GFK-2301.
■ PROFINET communications via the PROFINET Controller module IC695PNC001 and PROFINET
Scanner module IC695PNS001. For details, refer to the PACSystems RX3i PROFINET Controller
Manual, GFK-2571 and PACSystems RX3i PROFINET Scanner Manual, GFK-2737.
