1.3 RX3i Overview
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:

1.4 RX7i Overview
The RX7i control system hardware consists of an RX7i rack and up to seven Series 90-70 expansion racks.
The CPU resides in slot 1 of the main rack. RX7i racks use a VME64 backplane that provides up to four
times the bandwidth of existing VME based systems, including the current Series 90-70 systems for
faster I/O throughput. The VME64 base supports all standard VME modules including Series 90-70 I/O
and VMIC modules.
Expansion racks support Series 90-70 discrete and analog I/O, the Genius Bus Controller, and the HighSpeed Counter. The CPU provides an embedded auto-sensing 10/100 Mbps half/full duplex Ethernet
interface.
RX7i 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,
(IC698CRE020, CRE030 or CRE040). The redundancy communication path is provided by IC698RMX016
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.
Note: Extended operation with dissimilar CPU types is not allowed. During normal operation, the
primary and secondary units in an HSB redundancy system must have the same CPU model
type.
The primary and secondary units of an HSB redundancy system can have dissimilar model types for a
limited time, for the purpose of system upgrade only. Fail wait times for the higher performance CPU in
a dissimilar redundant pair may need to be increased to allow synchronization.
RX7i communications features include:
▪ Open communications support includes Ethernet, Genius, and serial protocols.
▪ A built-in 10/100mb Ethernet interface that has dual RJ45 ports connected through an auto-
sensing switch for upload, download and online monitoring. This eliminates the need for rackto-rack switches or hubs. The CPU Ethernet Interface provides basic remote control system
monitoring from a web browser and allows a combined total of up to 16 web server and FTP
connections. For details on Ethernet Interface capabilities, refer to PACSystems RX7i & RX3i
TCP/IP Ethernet Communications User Manual, GFK-2224.
▪ Two serial ports, one RS-232 and one RS-485.

2.1.3 Firmware Storage in Flash Memory
The CPU uses non-volatile flash memory for storing the operating system firmware. This allows firmware
to be updated without disassembling the module or replacing EPROMs. The operating system firmware
is updated by connecting to the CPU with a PC compatible computer and running the software included
with the firmware upgrade kit.
Each upgrade kit contains specific instructions for performing the upgrade. Depending on the CPU Model
and firmware version, the method employed is one of the following:
a) Use a serial port and the WinLoader utility (applies to CPU310, CPU315 & CPU320 models and
to CPE305/CPE310 models containing firmware versions prior to v7.30)
b) Use a USB port and memory stick for CPE302 (with firmware version 9.40 and later) or for
CPE305/CPE310 models (with firmware version 7.30 and later)
c) Use an Ethernet port and a Web-based mechanism for RXi CPUs, RX3i CPE330, CPE400 and RSTi-
EP CPE100/CPE115.
2.1.4 Operation, Protection, and Module Status
Operation of the CPU can be controlled by the three-position RUN/STOP Switch or remotely by an
attached programmer and programming software. Program and configuration data can be locked
through software passwords. The status of the CPU is indicated by the CPU LEDs on the front of the
module. For details, see Indicators for each PACSystems family.
Note: The RESET pushbutton is provided to support future features and has no effect on CPU
operation in the current version
2.1.5 Ethernet Global Data
Notes: Effective with RX3i firmware version 8.302, the CPE310/CPE305 CPUs also support EGD Class 1.
Prior to that firmware version, EGD was only available in the RX3i via the RX3i Ethernet Interface
Module (ETM001).
Effective with RX3i firmware version 8.603, CPE330 also supports EGD Class 1. This feature is
available on all firmware versions of RX3i CPE400, CPE302 and RSTi-EP CPE100/CPE115.
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 2 ms. Refer to the Section, A-3.6 for EGD Sweep
Impact for RX3i CPE302/CPE305/CPE310 and RSTi-EP CPE100/CPE115 Embedded Ethernet Interface.
During EGD configuration, PACSystems Ethernet interfaces are identified by their Rack/Slot location.

2.1.6 Embedded PROFINET Controller
The following CPUs support a feature that permits an Ethernet LAN to be configured for use as a
PROFINET Controller:
• RX3i CPE400
11
• Rx3i CPE330
12
• RSTi-EP CPE100/CPE115
13
If the Embedded PROFINET Controller feature is to be configured, it must be configured on LAN2 for the
CPUs listed above. In the case of RX3i CPE400 and RSTi-EP CPE100/CPE115, which are Standalone CPU’s,
this will be its only PROFINET Controller. In the case of CPE330, the Embedded PROFINET Controller can
co-exist with any rack-mounted PROFINET Controllers (IC695PNC001) present in its CPU rack.
To enable the Embedded PROFINET Controller in a project in Proficy Machine Edition14, select the RX3i
CPE400 (or CPE330) or RSTi-EP CPE100/CPE115 target in the PME Navigator (Figure 1) and open the
Hardware Configuration. On the Settings tab, change the designated LAN Mode of the selected port to
PROFINET. The PROFINET Controller node description then displays that a PROFINET node exists on the
selected LAN.

2.1.8 Removable Data Storage Devices (RDSDs)
The RX3i CPE302/CPE305/CPE310/CPE330 and CPE400 CPUsprovide the ability to transfer applications
to and from Removable Data Storage Devices (RDSD). Typically, these are USB-compatible devices, such
as a memory stick, smart phone, digital camera or an MP3 device. Once the data is copied to the RDSD,
it can be written to other RX3i / RSTi-EP CPUs of the same type. In order to copy using RDSD, no PME
programming software is needed. The RDSD interface requires a user-supplied flash memory device that
complies with the USB 2.0 Specification.
The USB port must be enabled in the RX3i configuration in order to transfer data between the CPU and
the RDSD. The compatible CPUs are shipped with the RDSD (USB) port enabled.
The RDSD load and store operations can include the following data:
▪ An entire application, including logic and configuration, reference table data, and cam files for Motion
applications. (Motion files and local logic for DSM motion applications are supported.) Configuration
can include Ethernet Global Data and Advanced User Parameters for the rack-based Ethernet
interface. (Although a complete, unmodified application must be placed on the RDSD, you can use an
options.txt file to download selected components of the application to the target CPU.)
▪ Passwords and OEM key, if any, are encrypted and written to the RDSD when the project is loaded
from the CPU. When the project is stored to a CPU that has no passwords or OEM key, those are
copied to the CPU.
Note: With Enhanced Security enabled, the RDSD update will fail if the RDSD source controller
has Level 4 password protection and the destination controller is password protected,
regardless of whether the passwords match.
With Legacy security, when the project is stored to a CPU that has passwords and/or
OEM key, the passwords must match or the store will fail.
▪ Fault tables are written to the RDSD before and after a load to or store from the RDSD.
▪ If a hardware configuration that disables the USB port is successfully stored to the CPU, the fault
tables will not be written to the RDSD at completion of the store operation.
Note: The USB port is for transfer of application data only. It is not intended for permanent
connection. Do not leave RDSD devices connected during normal operation.
Note: When using RDSD, all programming software connections must be in the Offline state for the
RDSD to function properly.
Note: CPE330 does not support Cfast memory cards as RDSD devices.
Note: CPE400 does not support any RDSD devices.

Chapter 2. CPU Features & Specifications
24 PACSystems* RX7i, RX3i and RSTi-EP CPU Reference Manual GFK-2222AD
Uploading a Project from the CPU to the RDSD
Notes: Only one application project can be stored to the RDSD at a time. Before the RX3i writes the
project to the RDSD, any previous application is removed; if a directory named PACS_Folder
exists on the RDSD at the start of the upload, it is deleted with all of its contents.
Flash devices write in whole memory blocks and memory block sizes vary among devices. The
amount of space used by a project may vary between RDSDs due to the differences in minimum
block sizes and therefore the number of blocks used by a project. The minimum amount of
memory required will be the size of the entire project plus an additional block for the options.txt
file, if used.
1. Place the CPU that contains the project to be transferred in RUN Mode or STOP Mode.
2. If PME is online with the RX3i, either go Offline or select Monitor mode.
3. Insert the RDSD into the USB connector on the CPU. (After 1 – 2 seconds, the RDSD LED turns solid
green.)
4. For CPE302/CPE305/CPE310, push the RDSD direction switch to the left (UPLOAD), then
momentarily depress the START pushbutton. For CPE330, depress the RDSD UPLD pushbutton.
5. Do not remove the RDSD from the CPU during the transfer.
▪ The RDSD LED blinks green during the transfer. This can take from 10 – 150 seconds, depending
upon the size of the project data.
▪ The RDSD LED should turn solid green, indicating that the transfer completed successfully.
▪ If the RDSD LED turns solid red, the transfer has failed. There will be a copy of the fault tables as
they existed at the end of the attempted transfer on the RDSD. Insert the RDSD into a PC which
has the PACS Analyzer software and select the plcfaultafter.dat file on the RDSD for fault table
analysis by the Analyzer. The PACS Analyzer software can be downloaded from the Support
website, www.geautomation.com.
▪ If the RDSD LED turns solid red, indicating an error, another RDSD operation cannot be initiated
until the device is disconnected then reconnected.
Caution
▪ If the RDSD is removed during data transfer from the CPU, the
integrity of the RDSD and the files on it cannot be guaranteed. The
RDSD status LED may indicate an RDSD fault, and the CPU will
abort the data transfer and remain in its current operating mode.
▪ The project files, consisting of the entire contents of the PACS_Folder
directory and all of its subdirectories, loaded on the RDSD must not be
modified. If they are modified, the files transferred to the CPU will be
invalid.
6. When the RDSD LED turns solid green, indicating the transfer has been successfully completed,
remove the RDSD from the CPU. The RDSD can now be used to transfer the application to other RX3i
controllers of the same model type.
You can copy the entire applications directory to another USB device and use that device as the
source for downloads to CPE302/CPE305/CPE310/CPE330 CPUs, provided none of the files in that
directory are changed in any way during the transfer.
Page 36
Chapter 2. CPU Features & Specifications
GFK-2222AD April 2018 25
Downloading a Project from the RDSD to the CPU
To download a project to the RX3i, the RDSD must contain a valid project, consisting of the hardware
configuration, application logic, and reference memory in a compiled format (originating from another
RX3i controller). The project files, consisting of the entire contents of the PACS_Folder directory and all
of its subdirectories, loaded on the RDSD must not be modified. If they are modified, the files transferred
to the CPU will be invalid.
By default, all project components are stored to the CPU and are written to flash. You can change this
operation by placing an options.txt file on the RDSD as described below.
1. Ensure that the RX3i is in STOP Mode
2. If PROFICY Machine Edition is online with the RX3i, either go Offline or select Monitor mode.
3. Connect the RDSD to the USB connector on the CPU that will be receiving the files. The RDSD LED
turns solid green.
4. For CPE302/CPE305/CPE310, move the RDSD direction switch to the right (DOWNLOAD), then
momentarily depress the START pushbutton. For CPE330, depress the RDSD DNLD pushbutton.
5. Do not remove the RDSD from the CPU during the transfer.
▪ If the target name in the RDSD is different from the target name in the RX3i, the RDSD LED will
blink red. If this is expected or acceptable, momentarily depress the START pushbutton again.
▪ The RDSD LED blinks green during the transfer. This can take from 10 – 150 seconds, depending
upon the size of the project data.
▪ The RDSD LED should turn solid green, indicating that the transfer completed successfully.
Unless the RUN/STOP Switch has been disabled in the hardware configuration just stored, it can
be used to place the RX3i into RUN Mode after the transfer.
▪ If the RDSD LED turns solid red, the transfer has failed.
- The target memory area(s) in the CPU are cleared. For example, if only the Logic is being
download from the RDSD and the store fails (e.g. stick pulled, problem with transfer or data),
Logic memory is cleared following the failed RDSD download. If other memory areas were
also queued up for transfer, those memory areas are also cleared as a result of the failure.
- There will be a copy of the fault tables as they existed at the end of the attempted transfer
on the RDSD. Insert the RDSD into a PC which has the PACS Analyzer software and select
the plcfaultafter.dat file on the RDSD for fault table analysis by the Analyzer.
- If the RDSD LED turns solid red, indicating an error, another RDSD operation cannot be
initiated until the device is disconnected then reconnected.
Caution
If the RDSD is removed during data transfer to the CPU, the
RX3i controller will generate a fatal fault (sequence store fault)
and SYS FLT LED will turn red. You will need to clear the fault
tables through a programmer connection or by power cycling
the CPU with the Energy Pack disconnected before attempting
to download again. Each type of data being downloaded (logic,
config, and/or data) is cleared within the target CPU.
6. When the RDSD LED turns solid green, indicating the transfer has been successfully completed,
remove the RDSD from the CPU.
The RUN/STOP Switch can be used to place the RX3i into RUN Mode after the transfer, unless it has
been disabled in the hardware configuration just stored. If the RUN/STOP Switch is disabled, you will
first need to connect with the programmer to place the RX3i in RUN Mode.

Using an Options.txt File to Modify Download Operation
An options.txt file can be used to modify the operation of the RDSD during a store to the RX3i. This is a
plain-text file which can contain some or all of the following statements, in any order. The format of each
option line is the option keyword, followed by a space, followed by either a capital Y or a capital N. The
option keyword must be spelled exactly as indicated below. If an option statement is omitted from the
file, the default value will be used.
If you want to use all of the default operations, the options.txt file is not necessary.

Security
When the application is written to the RDSD from a controller that has passwords and/or an OEM key
defined, the passwords and OEM key are encrypted and stored on the RDSD. When the project is written
from the RDSD to a CPE302/CPE305/CPE310/CPE33016, the passwords and OEM key are copied to it.
If an OEM key is defined on the RDSD, when transfer is complete, the OEM protection will be enabled
(locked). When an application is being stored to a CPE302/CPE305 that already has passwords and/or an
OEM key defined, the passwords/key on the RDSD must match the passwords/key in the target
CPE302/CPE305/CPE310/CPE330, or the transfer will fail.
RDSD Error Reporting
Errors are indicated when the RDSD LED becomes solid red (not blinking). All errors are reported in the
Controller fault tables. If the Controller has faults in its fault tables before it receives a store, the fault
tables are written to plcfaultbefore.dat and iofaultbefore.dat on the RDSD. If the Controller has faults in
its fault tables after it receives a store, the fault tables are written to plcfaultafter.dat and iofaultafter.dat
on the RDSD. Previous versions of these files are deleted before the transfer. If either fault table is empty,
the corresponding file is not written and will not be present.
To read any of the .dat files mentioned above, open PACS Analyzer. In settings, enable file analyze. Then
click the file analyze button on the main screen. Select as Input File the .dat file to be analyzed. Select as
Output File the filename and folder into which you wish to deposit the resulting text. The text will be in
English.
If a hardware configuration that disables the USB port is stored to the CPU, the fault tables will not be
written to the RDSD at completion of the store operation because the USB port will be disabled at the
end of the store process.

2.1.9 CPU Over-Temperature Monitoring and Behavior
RX3i CPE302, CPE305, CPE310, CPE330, and CPE400 models monitor the internal temperature of the
CPU.
• If the temperature rises to a near-critical level, these CPUs set the CPU Over Temperature Fault
(refer to section 3.2.7). The actual temperature varies from CPU to CPU, as each has a different
temperature specification.
• If the temperature continues to rise and reaches the specification limit, the CPU goes into a
firmware-controlled reset.
• Uniquely, the CPE400 turn on its TEMP LED, using amber.
• Following reset, the CPU continues to monitor the internal temperature.
• If the temperature falls sufficiently (i.e. by 10°C or 18°F), the CPU will automatically attempt to
restart.
• If the CPU is manually restarted before the temperature drops to the automatic restart level, the
CPU will attempt to restart, and will monitor its internal temperature as before.
• Upon successfully restarting, the Overtemp Fault will be recovered, providing the CPU has been
connected to an Energy Pack. If there is no Energy Pack connected, or if the Energy Pack has
discharged, the Overtemp Fault will be lost.
• The CPE400 always turns off its TEMP LED at power-up.

2.2.1 CPE400
Introduction
The IC695CPE400 is the first RX3i Standalone CPU. It operates in stand-alone fashion. All prior RX3i CPUs
slotted into an RX3i backplane. The CPE400 does not.
There are two mounting options:
1) As shipped, it mounts onto a DIN rail using a DIN-rail adaptor plate YAVD-I2C2-01-A.
2) Alternately, it mounts directly in a cabinet, using a panel-mount adaptor plate YA-l2-C2.04-A.
The mounting instructions and power requirements are documented in the RX3i IC695CPE400 1.2GHz
64MB Rackless CPU w/Field Agent Quick Start Guide, GFK-3002, and are not replicated here.
The physical features of the CPE400 are shown in Figure 2 and Figure 3.
Figure 2: CPE400 Front View and Features
The PACSystems* RX3i CPE400, part of GE’s Industrial Internet Control System, is the industry’s first
outcome optimizing controller. It augments real-time deterministic control with Field Agent technology,
delivering near real time advice through market analysis, fleet and enterprise data, or asset/process
knowledge to optimize the outcomes that today’s businesses require. The Predix™ enabled CPE400
provides reliable, secure communication and analytics using either cloud-based or edge-based outcome
optimizing apps. Controls can now be programmed to dynamically influence business outcomes,
generate new forms of revenue, and improve profitability.

Chapter 2. CPU Features & Specifications
36 PACSystems* RX7i, RX3i and RSTi-EP CPU Reference Manual GFK-2222AD
• The stand-alone CPE400 uses a 1.2GHz quad-core microprocessor and real-time hypervisor
technology to run real time deterministic control applications concurrently with Field Agent
technology without any adverse impact of one over the other.
• A built-in RX3i PLC:
o User may program in Ladder Diagram, Structured Text, Function Block Diagram, or C.
o Contains 64Mbytes of configurable data and program memory.
o Supports auto-located Symbolic Variables that can use any amount of user memory.
o Reference table sizes include 32k bits for discrete %I and %Q and up to 32k words each for
analog %AI and %AQ. Bulk memory (%W) also supported for data exchanges.
o Supports up to 512 program blocks. Maximum size for a block is 128KB.
• Field Agent technology is a platform for securely applying Predix applications and secure connectivity
to the Predix Cloud as well as running edge apps. Running the Field Agent concurrently with the realtime control applications allows the CPE400 to rapidly leverage external data. External monitoring
may be used to analyze and optimize entire business operations. The analysis can then be used to
dynamically adjust real-time industrial controls to align with changing business objectives in today’s
Industrial Internet age.
• Supports four independent 10/100/1000 Ethernet LANs. Three are located on the front panel, as
shown in Figure 1. LAN1 attaches via the upper, dedicated RJ 45 connector. LAN2 and LAN3 each
attach via a pair of internally-switched RJ 45 connectors. The fourth LAN, labeled EFA (Embedded
Field Agent), is located on the underside (Figure 2), and is specifically used for Field Agent
connectivity (see Field Agent bullet just above).
• The embedded communications interface has dedicated processing capability, which permits the
CPU to independently support LAN1 and LAN2 with:
o up to 48 simultaneous SRTP Server connections;
o up to 16 simultaneous Modbus/TCP Server connections;
o 32 Clients are permitted; each may be SRTP or Modbus/TCP;
o OPC UA Server with support for up to 5 concurrent sessions with up to 10 concurrent variable
subscriptions and up to 12,500 variables;
o up to 255 simultaneous Class 1 Ethernet Global Data (EGD) exchanges.
• The embedded PLC may use one or both of the Ethernet LAN2 ports to support the embedded
Simplex PROFINET I/O Controller. PROFINET supports up to 32 I/O devices with update rates of 1 –
512ms. I/O device update rates of 8ms and faster are possible with 16 or fewer devices. Update rates
of 16ms and higher result whenever more than 16 devices are configured.
• Media Redundancy Protocol (MRP) allows the CPE400 to participate in a PROFINET I/O network with
MRP ring technology. This eliminates the I/O network as a single point of failure. The CPE400 may be
used as either a Media Redundancy Manager or Media Redundancy Client.
Page 48
Chapter 2. CPU Features & Specifications
GFK-2222AD April 2018 37
• Effective with firmware version 9.30, the CPE400 supports Hot Standby Redundancy with PROFINET
IO. In this configuration, LAN3 is used as a high-speed data synchronization link between the two
redundant CPUs. Only the Primary and Secondary CPUs may be attached to LAN3. Two OLED menu
items support Redundancy operation: RDN Info and RDN Command. The RACT and RBOK LEDs reflect
the status of the Redundant CPUs. Refer to the PACSystems Hot Standby CPU Redundancy User
Manual, GFK-2308 for details and restrictions.
• Effective with firmware version 9.30, the CPE400 supports two independent Redundant IP
addresses, one for LAN1 and one for LAN2. LAN2 Redundant IP is supported when configured for
Ethernet mode only. Redundant IP is supported by the SRTP Server, Modbus TCP Server, and EGD
protocols. It is not possible to use Redundant IP with the OPC UA Server or with the Ethernet
firmware update web page.
• Effective with firmware version 9.40, the CPE400 Serial Port (COM1) is supported. Refer to Section
2.2.1.13.
• The CPE400 is secure by design, incorporating technologies such as Trusted Platform Modules,
secure boot, and encrypted firmware updates.
• Optional Energy Pack, IC695ACC403, allows CPE400 to instantly save user memory to non-volatile
storage in the event of loss of power. Upon restoration of power, with the ACC403 connected, the
CPE400 PLC function is able to resume operations from the state saved at power-down.
• OPC UA Sweep Mode & Sweep Time: The CPE400’s sweep mode and sweep time are available
through the OPC UA server. The Sweep Mode variable reports the controller’s current mode:
Stop Disabled, Run Enabled, Stop Enabled, Run Disabled, Stop Faulted, and Stop Halted. The
Sweep Time variable reports the sweep time in seconds. These variables are located under
GE Device Information -> PACSystems RX3i -> Controller.
• An OLED display that provides access to basic CPE400 status and control information including each
LAN’s configured IP Address.
• Alternate panel-mount adaptor plate included.
• Achilles Level 2 Communications Certification
40
• Ability to display serial number and date code in PME Device Information Details.
• Coordinated Universal Time (UTC) and Daylight Savings Time (DST) support.
• Operating temperature range -40C to 70C. (-40F to 158F) The maximum operating temperature
varies according to installation altitude: 70C at 0m to 2000m, 65C at 2000m to 3000m, and 60C
at 3000m to 4000m.
40
The CPE400’s PACSystems Runtime is Achilles Level 2 certified in Release 9.20. Embedded Field Agent (EFA) certification is

Micro-SD Card Interface
The Micro SD Card slot is located on the right-hand side of the equipment (Figure 2), level with the OLED
display. This port is not functional at time of publication. Once functional, it will support the Removable
Data Storage Device features discussed in Section 2.1.8.
The interface supports SD, SDHC and SDXC µSD-Cards up to Version 3.0.
Insert the card into to slot, oriented as described below. Apply pressure it until you feel some resistance.
The card will latch into place and can then be read by the equipment. Apply pressure again to remove
the card from the slot.
Figure 4: CPE400 Micro-SD & USB Pinouts
Note that the µSD-Card needs to be inserted in the slot with the correct orientation. The pins of the card
need to face towards the front of the equipment (Figure 4).
A cover and screw are provided. To minimize CPE400 susceptibility to electrical noise interference, keep
the cover in place during normal operation.

Ethernet Ports CPE400
CPE400 supports a total of four independent 10/100/1000 Ethernet Local Area Networks (LANs).
• LAN1 connects to the uppermost faceplate RJ45 connector (Figure 2). It is not switched.
• LAN2 connects to the next two lower faceplate RJ45 connectors (Figure 2). These two
connectors are switched internally. If desired, one or both of these ports may be configured as
the Embedded PROFINET port.
• LAN3 connects to the two lowest faceplate RJ45 connectors (Figure 2). These two connectors
are also switched internally. LAN3 may only be used in Redundancy applications. See Section
2.2.1.10, Hot Standby Redundancy.
• The fourth LAN is marked EFA (Embedded Field Agent) and is located on the underside of the
equipment (Figure 3). It supports the Field Agent function and may not be used as a standard
Ethernet port. Refer to Section 2.2.1.9, Field Agent, below.
Each of the embedded Ethernet interfaces automatically senses the data rate (10 Mbps or 100 Mbps or
1 Gbps), communications mode (half-duplex or full-duplex), and cabling arrangement (straight-through
or crossover) of the attached link.
For improved performance, the LAN1, LAN2 and LAN3 are serviced by a dedicated microprocessor core.
In this way, the servicing of the Ethernet ports is independent of the controller logic, I/O scanning and
Field Agent activities. The EFA port is independently serviced by two of the four microprocessor cores.
This superior level of servicing is required at the higher communications rates.
LAN1 and LAN2 may be used to communicate with the PME programming software using the Service
Request Transport Protocol (SRTP, a proprietary GE protocol, used primarily for communication with the
programmer). The EFA port cannot be used for this purpose.
LAN2 may be configured as an embedded PROFINET Controller, as discussed in Section 2.1.6. While
configured as a PROFINET Controller, LAN2 may concurrently be used for Ethernet protocols. This topic
is discussed in the PACSystems RX3i PROFINET IO Controller User Manual, GFK-2571F or later.
LAN2 and LAN3 each support a pair of RJ45 connectors. In this way, network devices on the same LAN,
but operating at different data rates may be connected to a suitably configured port.
To establish Ethernet communications between the PME programming and configuration software and
the CPU, you first need to know the target IP address. Use the OLED menu function to check
the IP Address. For default IP Address and other details, refer to Establishing Initial Ethernet
Communications, Section 3.4.1.
CAT 5 cables (or superior) are required for proper operation with 100/1000BaseT LANs. The pin
arrangements are:

Field Agent
The Embedded Field Agent (EFA) port on the underside of CPE400 (Figure 3) is an Ethernet port dedicated
to the Field Agent functionality.
Figure 5 shows a typical Field Agent application, in which the role of the CPE400 Embedded Field Agent
(EFA) is to gather data locally, then securely transfer selected data to the Predix Cloud via the EFA port.
The PACSystems RX3i maintains control over the remaining Ethernet ports on the CPE400, as well as its
serial port. Data from the local environment, obtained via any of these ports, can be manipulated by the
RX3i PLC and tagged for use in the Field Control application.
The remote user with an acceptable security profile can then access data in the cloud from multiple
installations, aggregate selected data and make decisions based on the bigger picture. For instance, the
CPE400 could be installed in a control system monitoring a single wind turbine. The remote user might
be monitoring several hundred such turbines. With a suitable dashboard-style application on his
computer, the remote user could identify turbines that need to come offline for maintenance, or turbines
whose power generation output could be enhanced or retarded to fit demand.

Field Agent Configuration
Start the Embedded Field Agent (EFA)
After providing the CPE400 with power, the Embedded Field Agent (EFA) application will begin to boot.
The FAOK LED will start blinking to indicate when the EFA has booted and is ready for user logins. (This
may take about two minutes.)
Log into the Web Console
To log into the Web Console:
1. Connect a computer to the EFA’s IICS Cloud Port or EFA Port.
2. Configure the computer’s network adapter to be an address on the Field Agent network.
• The EFA’s default IICS Cloud Port or EFA Port is assigned 172.31.0.100 with subnet mask
255.255.0.0. Set your computer’s network adapter to any other IP address on the 172.31.x.x
network. For example, 172.31.0.101 with subnet mask 255.255.0.0.
3. Use the OLED Menu to enable Configuration Mode as follows:
• From the Main Menu, select the “FA Settings” menu item.
• From the FA Settings Menus, select the “Commands” menu item.
• From the Commands Menus, select the “Config Mode” menu item.
• Confirm entering Config Mode.
• Configuration Mode will remain active for one hour or until the above steps are repeated to
disable Configuration Mode.
Note: Browsing to the Web Console too soon may result in seeing an Authentication Required or
similar drop-down/pop-up dialog. Entering a user name and password into this dialog will
not permit a log-in to the Web Console. Wait for the Field Agent to fully boot as indicated by
the FAOK LED and re-attempt to browse to the Web Console. Closing the current browser
tab or window may also be required.
4. Using Google Chrome (recommended), browse to the Field Agent’s Web Console at
https://172.31.0.100:8443/system/console.
5. Since the Web Console uses a self-signed certificate, the browser will warn that the connection is
not private. When prompted, accept the connection.

Configure the Network
EFA IP Addresses
By default, the Embedded Field Agent’s WAN interface is set to a static address of 172.31.0.100 with a
subnet mask of 255.255.0.0.
To change the WAN IP address
1. Verify that the WAN Ethernet cable is connected to the IICS Cloud port / EFA Port. If a network proxy
is needed to connect the field agent to the WAN, refer to the section Configure a Network Proxy.
2. From the Web Console, navigate to the Technician Console, Network Configuration page.
Figure 9: Technician Console, Network Configuration page
3. Set the WAN interface settings appropriately for the Field Agent’s network. DHCP can be used for
networks where a DHCP server is available, and a static IP address for networks where each device
is manually assigned an address. Click the Save button to accept the changes.
Note: The DNS servers can also be configured to be obtained automatically or specified statically.
When using a static IP address, DNS servers must also be specified statically.

Chapter 2. CPU Features & Specifications
GFK-2222AD April 2018 49
Configure a Network Proxy
A Network Proxy is only required when your network architecture is configured to restrict access directly
to the Internet. Contact your network administrator for the Network Proxy information.
If a network HTTP/HTTPS proxy server is used to route traffic from the intranet to the Internet, the
network proxy must be configured in the Web Console under Technician Console, Network Configuration.
To add or update a network proxy server, check the “Enable HTTP/HTTPS Proxy” check box, enter the
proxy server’s address and port in the form “proxy:port” into the Proxy Settings text box, and press the
Save button.
Figure 10: Enter Proxy Server Address
To verify the Field Agent can successfully use the newly configured network proxy to reach the Internet,
use the Test Connection feature of the Field Agent Updater page in the Web Console under Technician
Console, Field Agent Updater. Internet reachability can be tested by using either the default Update URL
or any other desired URL and pressing the Test Connection button.
Figure 11: Test Connection
If the URL is reachable, a Test Connection Succeeded message is displayed below the Test Connection
button after the button is pressed. Otherwise, a message will appear indicating that the Test Connection
attempt failed.

Configure Time Synchronization
In order for industrial data time-stamping and Field Agent diagnostic information to operate reliably, it
is important for the Field Agent to have an accurate time source. The Field Agent has two methods of
synchronizing time – either by using a Network Time Protocol (NTP) server or by pulling time from a web
page hosted by an HTTPS web server with its own reliable time source. Either method can be configured
in the Web Console under Technician Console, Time Sync Configuration.
Figure 12: Technician Console, Time Sync Configuration
Using NTP Time Synchronization
By default, time synchronization is configured to use the time.windows.com NTP Server. If a valid network
path to the Internet exists, time will be synchronized when the Field Agent boots and continuously while
running. The current date and time on the Field Agent is displayed above the Save button on the Time
Sync Configuration page when the page loads, and can be updated by pressing the Save button or
reloading the page.
To change the NTP server to use for time synchronization enter the new NTP server URL in the NTP Server
textbox and press the Save button. If the new server was successfully configured, a success statement
will be displayed and the updated time will be displayed. If the time and date was more than 20 minutes
out of date prior to time synchronization occurring after pressing the Save button, the Web Console
session may end and an error message may be presented indicating that the session’s timeout had been
reached. Log back into the Web Console to verify the time was updated as expected.
Using HTTPS Time Synchronization
Time synchronization can also be configured to use an HTTPS web server's time by pulling it from the
header of the web page it serves. To configure HTTPS time synchronization, select the HTTPS Server radio
button on the Time Sync Configuration page, enter a valid HTTPS URL, and press the Save button. If a
network proxy is in use, this time synchronization method will only work with HTTPS URLs that do not
require a network proxy in order to reach them.
If the new HTTPS URL was successfully configured after pressing the Save button, a success statement
will be displayed and the updated time will be displayed. If the time and date was more than 20 minutes
out of date prior to time synchronization occurring after pressing the Save button, the Web Console
session may end and an error message may be presented indicating that the session’s timeout had been
reached. Log back into the Web Console to verify the time was updated as expected.

Wrap-up
1. For security, toggle Configuration Mode to disable access to the Predix Machine Web Console.
2. Disconnect the local computer once enrollment has been completed.
3. Configure and Manage the activities on the EFA using Predix EdgeManager. This involves
selecting tags in the CPE400’s OPC-UA server and configuring these as read, write or read/write.
In this way, the system is set up to allow data to pass securely from the CPE400 to the Predix
Cloud, where that data may be used by external cloud applications. Detailed steps are as follows:
a. Using a computer, download the default EFA configuration from:
https://digitalsupport.ge.com/communities/en_US/Download/IC695CPE400-EmbeddedField-Agent-EFA-Configuration-Templates
b. Configure the OPC UA Data Source to opc.tcp://localControllerHost:4840
c. Configure the OPC UA tags and subscriptions in the OPCUA Machine Adaptor xml file.
d. Configure the data destination in the WebSocket River configuration.
e. Leave the Store and Forward service enabled.
f. Zip up the configuration and upload it to the Edge Manager repository.
g. Deploy the configuration to the Field Agent using Edge Manager.
Note that data will now be transferring from the Field Agent to the Predix Time Series Database.
Note that communications between the CPE400 and the Predix Cloud is secured using authentication
and encryption.
Note that the Field Agent firmware within the CPE400 may need to be updated from time to time. GE
recommends that all such firmware be kept up-to-date. The Technician has the ability to configure the
Field Agent for scheduled automatic updates or manual updates. Refer to the chapter on Updating the
Field Agent in the Field Agent User’s Guide, GFK-2993.

Hot Standby Redundancy
With firmware version 9.30 or later, it is possible to configure the CPE400 as a Hot Standby Redundancy
CPU with PROFINET IO. The two ports on LAN3 are used exclusively for this purpose: they provide a highspeed data synchronization link between the two CPUs. Connect the upper LAN3 port of the Primary
CPU to the upper LAN3 port of the Secondary CPU and connect the lower LAN3 port of the Primary to
the lower LAN3 port of the Secondary, as shown in Figure 13. Note that no additional hardware, other
than the two redundant CPUs, may be connected to LAN3.
Figure 13: LAN3 Interconnects for Hot Standby Redundancy
To enable redundancy in a CPE400 project, select the CPE400 target in the PME Navigator and use the
Property Inspector to change the Enable Redundancy target property to True.
Important: Set the Background Window Timer to a minimum of 5ms in both the Primary and Backup
CPE400 hardware configurations. The Background Window Timer setting may be found on the Scan Tab
in the CPE400’s hardware configuration.
Once configured for HSB Redundancy, the RACT and RBOK LEDs (Figure 2) become functional.
• RACT indicates the Local CPU is Ready & Active;
• RBOK indicates the Remote CPU is Ready.
These two LEDs are also reflected in the Status Data of the CPU and are presented as OPC UA Variables.
The OLED display includes two menu items used in conjunction with Redundancy:
• RDN Info provides status information via the OLED display.
• RDN Command permits the operator to perform a Role Switch.
To support Hot Standby operations, LAN2 is configured as a PROFINET IO Controller. For additional
details, refer to Section 2.1.6, Embedded PROFINET Controller.
For further details, refer to the PACSystems Hot Standby CPU Redundancy User Manual, GFK-2308 (rev
L or later).

54 PACSystems* RX7i, RX3i and RSTi-EP CPU Reference Manual GFK-2222AD
Redundant IP Addresses
Effective with firmware version 9.30, the CPE400 supports two independent Redundant IP addresses,
one for LAN1 and one for LAN2. LAN2 Redundant IP is supported when configured for Ethernet mode
only.
Redundant IP is supported by the SRTP Server, Modbus TCP Server, and EGD protocols. It is not possible
to use Redundant IP with the OPC UA Server or with the Ethernet firmware update web page.
For further details, refer to the PACSystems Hot Standby CPU Redundancy User Manual, GFK-2308 (rev
L or later).
Error Checking and Correction
RX3i Redundancy CPUs provide error checking and correction (ECC), which results in slightly slower
system performance, primarily during power-up, because it uses an extra 8 bits that must be initialized.
For details on ECC, refer to the PACSystems Hot Standby CPU Redundancy User Manual, GFK-2308.
Note: Multiple Recoverable Memory Error faults may be generated when a single-bit ECC error is
detected. When a single-bit ECC error is detected, the value presented to the
microprocessor is corrected. However, the value stored in RAM is not corrected until the next
time the microprocessor writes to that RAM location.
Serial Port CPE400
Effective with firmware version 9.40, the CPE400 Serial Port (COM1) is supported. Note that it only
supports the Serial IO protocol at this time.
CPE400 is equipped with an RJ45 serial port. It is marked COM and is located on the underside of the
equipment (Figure 3). Its default settings are RS-232C, 115kBaud, 8 data bits, no parity and 1 stop bit. For
pinout, refer to Section 5.2.3.3. For more general information on serial port usage, refer to Chapter 5.
Note that CPE400 does not support PME connection via the serial port; use an Ethernet port,

Energy Pack Connector
The CPE400 compatible Energy Pack, IC695ACC403, is supplied with a purpose-built cable which installs
in the connector shown in Figure 3.
Use of the Energy Pack is optional. Once charged up, the ACC403 allows the CPE400 to instantly save
user memory to non-volatile storage in the event of loss of power. Upon restoration of power, with the
ACC403 connected, the CPE400 PLC function is able to resume operations from the state saved at
power-down.
Refer to the PACSystems RX3i Rackless Energy Pack IC695ACC403 Quick Start Guide, GFK-3000, for
complete wiring and grounding instructions.
Note that the connector shown in Figure 3 is not supplied with the CPE400.
Input Power Connector
If no Energy Pack is to be connected, refer to Section 2.4 of the RX3i IC695CPE400 1.2GHz 64MB Rackless
CPU w/Field Agent Quick Start Guide, GFK-3002. Otherwise, refer to the PACSystems RX3i Rackless
Energy Pack IC695ACC403 Quick Start Guide, GFK-3000,
Backwards Compatibility of CPE400
In Proficy Machine Edition, the CPE400 is identified as a PLC within the PACSystems RX3i Rackless
family. To convert an existing project which uses any other PLC, use the Family Conversion feature in
PME. Be aware of the constraints involved. For instance, the first PROFINET Controller in an RX3i CPU320
application will be assigned to the Embedded PROFINET Controller feature (refer to Section 2.1.6) of the
CPE400.

Replacement of Real-Time Clock Battery on CPE400
Figure 15: Location of RTC battery on CPE400
The CPE400 is shipped with a real-time clock (RTC) battery installed on an internal circuit board (see
Figure 15). This battery will need to be replaced periodically by a qualified service technician. Typically,
no action is required during initial installation.
Should the RTC battery fail, the CPU date and time will be reset to 12:00 AM, 01-10-2000 at start-up. The
CPU operates normally with a failed or missing RTC battery; however, the initial CPU time-of-day (TOD)
clock information will be incorrect.
There are no diagnostics or indicators to monitor RTC battery status. The RTC battery has an estimated
life of 5 years and must be replaced every 5 years on a preventative maintenance schedule.
To replace a depleted battery:
1. Power down the CPE400.
2. Disconnect the external cables attached to the CPE400, labelling each for later reconnection.
3. Remove the CPE400 from its installed location.
4. Take the CPE400 to a clean environment.
5. Remove the DIN-rail or panel-mount adaptor plate, as applicable.
6. Place the CPE400 on a workbench so that the heat-sink adjacent to the GE logo on the front panel is
facing up.
7. With ESD protection in place, remove the four screws holding the upper side heat sink in place.
8. Remove the heat sink. This exposes the circuit board, connectors and coin battery shown in Figure
15.
9. Take care to collect any thermal pads that may have been dislodged. These will be needed during
reassembly.
Page 69

shown).
11. Using a non-conductive pliers, grip the battery and simultaneously hold back the retaining clip so it
is clear of the battery.
12. Remove the depleted battery and dispose of it by an approved method.
13. Install the replacement battery so that the inscribed positive face is up.
14. Check that the retaining clip has engaged the edge of the newly installed battery.
15. Apply any dislodged thermal pads to the surface of the corresponding components on the circuit
board.
16. Replace the heat sink.
17. Tighten all four retaining screws to 0.6Nm.
18. Reattach the adaptor plate removed in step 5.
19. Restore the CPE400 module to its original location and secure it in place.
20. Reconnect all cables to their original connectors.
21. Turn power back on.
22. If needed, set the current date and time via Proficy Machine Edition.
The replacement battery must be IC690ACC001 from GE Automation & Controls, or an equivalent, such
as Rayovac™ Lithium BR2032 Coin Cell 3V 190mAh -40°C to +85°C.
Warning
Use of a different type of battery than that specified here may
present a risk of fire or explosion.
Battery may explode if mistreated. Do not recharge,
disassemble, heat above 100°C (212°F), or incinerate.
Caution
To avoid damage from electrostatic discharge, use proper precautions
when performing these procedures:
▪ Wear a properly functioning antistatic strap and be sure that you are
fully grounded. Never touch the printed circuit board, or components
on the board, unless you are wearing an antistatic strap.
▪ Any surface upon which you place the unprotected circuit board
should be static-safe, facilitated by antistatic mats if possible.
Extra caution should be taken in cold, dry weather, when static charges can
easily build up.

Figure 18: CPE330 Front View & Features
Page 73
Chapter 2. CPU Features & Specifications
62 PACSystems* RX7i, RX3i and RSTi-EP CPU Reference Manual GFK-2222AD
Serial Ports CPE330
CPE330 is not equipped with a serial port. Use the embedded Ethernet ports for all communications with
the CPU; use IC695CMM002 or IC695CMM004 modules for serial communications.
Ethernet Ports CPE330
CPE330 supports two independent 10/100/1000 Ethernet Local Area Networks (LANs).
• LAN1 connects to the uppermost RJ45 connector (Figure 18). It is not switched.
• LAN2 connects to the two lower RJ45 connectors. They are switched internally.
Space is provided beside each connector (Figure 18) to record the IP address used on each LAN.
Each of the embedded Ethernet interfaces automatically senses the data rate (10 Mbps or 100 Mbps or
1 Gbps), communications mode (half-duplex or full-duplex), and cabling arrangement (straight-through
or crossover) of the attached link.
Any of the embedded Ethernet ports may be used to communicate with the Proficy Machine Edition
(PME) programming and configuration software using the Service Request Transport Protocol (SRTP, a
proprietary GE protocol, used primarily for communication with the programmer).
For default IP Address and other details, refer to Establishing Initial Ethernet Communications, Section
3.4.1.
Ethernet Network Configuration CPE330
The user must be careful when assigning IP Addresses and Subnet Masks for CPE330:
• Each LAN supports a unique IP Address
• LAN1 and LAN2 interfaces should not be configured for the same network.
By default, PME prohibits configuring both LAN interfaces on an overlapping IP subnet.
Care must also be taken when assigning IP Addresses and subnet masks to each LAN so that each
network does not overlap any remote subnets in the network infrastructure:
• Subnets overlap with one another when the subnet portions of the IP Addresses are not
completely unique
• Overlapping subnets may result in intermittent Ethernet communications, or none. This would
be due to packets being routed to the wrong LAN.
• Duplicate IP Addresses may also result in intermittent Ethernet communications, or none. This
is due to collisions on the LAN induced by two devices with the same IP Addresses
communicating at the same time.
Ethernet Gateway Operation CPE330
The CPE330 allows configuration of an Ethernet gateway on both LAN1 and LAN2. Since the CPE330
contains two LAN interfaces, each one supporting a unique IP Address, only one gateway is active at a
time.
• Whenever a gateway is configured on only one of the two LAN interfaces and the other is not
configured (0.0.0.0), the single gateway is shared by both interfaces;
• Whenever a gateway is configured on both LAN interfaces, the LAN1 gateway is given priority
over the LAN2 gateway if LAN1 is functional. For example, in the event the LAN1 cable is
disconnected, the CPE330 will use the LAN2 gateway as a backup.
PROFINET Controller
An Embedded PROFINET Controller may be configured on LAN2. For additional details, refer to Section
2.1.6, Embedded PROFINET Controller.

Error Checking and Correction
RX3i Redundancy CPUs provide error checking and correction (ECC), which results in slightly slower
system performance, primarily during power-up, because it uses an extra 8 bits that must be initialized.
For details on ECC, refer to the PACSystems Hot Standby CPU Redundancy User Manual, GFK-2308.
Note: Multiple Recoverable Memory Error faults may be generated when a single-bit ECC error is
detected. When a single-bit ECC error is detected, the value presented to the
microprocessor is corrected. However, the value stored in RAM is not corrected until the next
time the microprocessor writes to that RAM location.

Replacement of Real-Time Clock Battery on CPE330
The CPE330 is shipped with a real-time clock (RTC) battery installed
(see Figure 20). There is no isolation barrier between the battery and
the circuit. This battery will need to be replaced periodically. Typically,
no action is required during initial installation.
Should the RTC battery fail, the CPU date and time will be reset to
12:00 AM, 01-10-2000 at start-up. The CPU operates normally with a
failed or missing RTC battery; however, the initial CPU time-of-day
(TOD) clock information will be incorrect.
There are no diagnostics or indicators to monitor RTC battery status.
The RTC battery has an estimated life of 5 years and must be replaced
every 5 years on a preventative maintenance schedule.
To replace a depleted battery,
1. Power down the RX3i rack.
2. Disconnect cables attached to the CPE330 module, labeling each
for later reconnection.
3. Remove the CPE330 module.
4. Take the CPE330 module to a clean environment.
5. Place the module on a workbench with the heat-sink side down.
6. With ESD protection in place, remove the four screws holding the
upper side sheet metal in place.
7. Remove the sheet metal. This exposes the circuit board,
connectors and coin battery shown in Figure 20.
8. Using a non-conductive pliers, grip the battery and
simultaneously hold back the retaining clip so it is clear of the
battery.
9. Remove the depleted battery and dispose of it by an approved
method.
Figure 20: Location and
Orientation of Real-Time Clock
Battery in CPE330
10. Install the replacement battery so that the inscribed positive face is towards the green connector
(i.e. downwards as shown in Figure 20).
11. Check that the retaining clip has engaged the edge of the newly installed battery.
12. Replace the sheet metal cover.
13. Tighten all four retaining screws to 0.9Nm (8 in-lbs).
14. Restore the CPE330 module to its original location and secure it in place.
15. Reconnect all cables to their original connectors.
16. Turn power on to the RX3i rack.
17. If needed, set the current date and time via PME or using SVC_REQ 7 (refer to PACSystems RX7i
and RX3i CPU Programmer’s Reference Manual, GFK-2950 Chapter 6).
Note: Battery replacement on CPE302/CPE305 & CPE310 is different: see Figure 25.

Replacement Real-Time Clock Battery
The replacement battery must be IC690ACC001 from GE Automation & Controls, or an equivalent, such
as Rayovac™ Lithium BR2032 Coin Cell 3V 190mAh -40°C to +85°C.
Warning
Use of a different type of battery than that specified here may
present a risk of fire or explosion.
Battery may explode if mistreated. Do not recharge,
disassemble, heat above 100°C (212°F), or incinerate.
Caution
To avoid damage from electrostatic discharge, use proper precautions
when performing these procedures:
▪ Wear a properly functioning antistatic strap and be sure that you are
fully grounded. Never touch the printed circuit board, or components
on the board, unless you are wearing an antistatic strap.
▪ Any surface upon which you place the unprotected circuit board
should be static-safe, facilitated by antistatic mats if possible.
Extra caution should be taken in cold, dry weather, when static charges can
easily build up.

Backwards Compatibility of CPE330 with CPU320, CRU320, or CPU315
The CPE330 may be interchanged with a corresponding CPU320/CRU320 with no upgrade to Proficy
Machine Edition (PME) software. Logic and configuration equality in PME are maintained when storing
the same project to either a CPU320/CRU320 or a CPE330.
An Extra Option Module fault is logged in the Controller Fault Table on the CPE330’s slot location after
downloading a CPU320/CRU320 configuration to a CPE330. This indicates that the Embedded Ethernet
interface did not receive a configuration. This fault is expected and does not interfere with normal
controller operation.
Migration of CPU315 applications to the CPE330 is possible with no upgrade to PME by converting them
to a CPU320 application and storing the project to the CPE330.
Versions of PME with native CPE330 support allow either a CPU320/CRU320 or a CPE330 configuration
to be stored to the CPE330. When a CPE330 is configured as a CPU320/CRU320, Ethernet properties
cannot be configured. However, the embedded Ethernet ports may be used with their previously
configured IP Addresses or their default IP Addresses if the default IP Addresses were never changed.
Since CPE330 has no serial ports, any serial port activity associated with the previous CPU320/CRU320
application needs to be migrated to a suitable rack-based module (IC695CMM002 or IC695CMM004).
To download projects intended for the CPU320/CRU320 to a CPE330 with versions of PME that do not
support the CPE330, you must change the CPE330’s compatibility setting. To change the compatibility
setting, perform the following operations:
1. Remove any USB stick that might be attached to the USB connector on the CPE330.
2. Place the RUN/STOP switch on the CPE330 in the STOP position.
3. Hold down the RDSD UPLD button and turn power on to the CPE330. Continue to depress the RDSD UPLD
button until the CPE330 powers up and displays one of the following patterns on the LEDs.

ii. When the desired compatibility setting is displayed, press the RDSD UPLD button to save the setting and
allow the CPE330 to continue its normal startup procedures with the new setting. The setting is
maintained over a power cycle and firmware upgrade.
Note that with versions of PME that do not have native CPE330 support, only CPU320 projects can be
stored to a CPE330 that is in CPU320 compatibility mode. Similarly, only CRU320 projects can be stored
to a CPE330 that is in CRU320 compatibility mode.
Users of a CPE330 with PME versions 8.60 SIM8 or later do not need to change this compatibility setting.
PME versions 8.60 SIM8 or later allow for storing a CPU320 or CRU320 project without the need to change
this setting. By factory default, the CPE330 identifies as a CPU320.
Note that CPE330s with firmware versions 8.45 through 8.60 support compatibility with the CPU320 and
CPU315 only. The compatibility setting using the RDSD buttons (described above) is not supported for
these firmware versions. Beginning with firmware version 8.70, CPE330s support compatibility with the
CPU320, CPU315, and CRU320 using the RDSD buttons to set the compatibility setting.

Serial Ports
These ports provide serial interfaces to external devices and can be used for firmware upgrades. For
serial port pin assignments, electrical isolation, and details on serial communications, refer to Chapter 5.
CPE302/CPE305: one RS-232 port (using RJ-25 connector).
CPE310: one RS-232 port (COM1) and one RS-485 port (COM2).
The RS-232 port does not supply the 5Vdc power offered by other RX3i and Series 90-30 CPUs.
Use cable IC693CBL316 to connect to the serial RJ-25 port on the CPE302/CPE305. This 3m shielded
cable provides a 9-pin D-connector on the other end.
Ethernet Port
The embedded Ethernet interface connects via one RJ45 Ethernet port that automatically senses the
data rate (10 Mbps or 100 Mbps), communication mode (half-duplex or full-duplex), and cabling
arrangement (straight-through or crossover) of the attached link.
The embedded Ethernet interface supports communications with the Proficy Machine Edition (PME)
programming and configuration software using the proprietary SRTP protocol. The CPE302/CPE305
/CPE310 CPUs provide two SRTP-server connections.
Refer to Establishing Initial Ethernet Communications, Section 3.4.1.

Real-Time Clock Battery CPE302/CPE305 & CPE310
The CPE302, CPE305 and CPE310 are shipped with a
real-time clock (RTC) battery (IC690ACC001) installed
(Figure 25), and with an isolation barrier on the
battery. Remove the isolation barrier via its pull-tab
before installing the CPE302, CPE305 or CPE310
module; otherwise the battery will not function.
There are no diagnostics or indicators to monitor RTC
battery status.
The RTC battery has an estimated life of 5 years and
must be replaced every 5 years on a preventative
maintenance schedule.
If the RTC battery fails, the CPU date and time is reset
to 12:00 AM, 01-10-2000 at startup. The CPU operates
normally with a failed or missing RTC battery; only the
initial CPU TOD clock information will be incorrect.
Note: Battery replacement on CPE330 is

Backwards Compatibility of CPE310 with CPU310
The CPE310 may be swapped with a CPU310 with no upgrade to the Proficy Machine Edition Logic
Developer-PLC programming software. Logic and configuration equality in the programming software is
maintained when storing the same project to either a CPU310 or a CPE310. Proficy Machine Edition
versions that recognize the CPE310 (7.0 SIM3 and newer), allow either a CPU310 configuration or a
CPE310 configuration to be stored to the CPE310. For all programming software versions (both current
and legacy) a CPU310 device can accept only a CPU310 configuration.
Legacy CPU310 Projects
The CPE310 supports CPU310 projects. Proficy Machine Edition versions earlier than 7.10 SIM 3 interpret
the CPE310 as a CPU310. The CPE310 can be configured as a CPU310 using Proficy Machine Edition
versions as old as 5.5, Service Pack 1.
RDSD Port
If a CPU310 configuration is stored to a CPE310, the RDSD port is enabled to allow you to transfer
CPU310 projects to CPE310 models without using Proficy Machine Edition.
Fault Behavior
Faults related to the embedded CPE310 Ethernet interface may be generated on power-up, as detailed
in the following section.
Replacing a CPU310 with a CPE310
▪ A CPE310 that is configured as a CPU310 logs the following faults in the Controller fault table:
- A LAN Transceiver Fault is generated because the RX3i system detects that the embedded
Ethernet module does not have a network connection.
- An Extra Option Module fault is generated because the embedded Ethernet module is detected
as an unconfigured module.
- If the Energy Pack capacitor pack is disconnected or fails, the legacy faults for a missing or failed
battery are logged.
▪ When a CPE310 is configured as a CPU310, Ethernet properties cannot be configured and there
should be no cable connected to the Ethernet port.
▪ When a CPE310 is configured as a CPU310, the Show Status dialog box in Proficy Machine Edition
displays CPU310A.
Page 89
Chapter 2. CPU Features & Specifications
78 PACSystems* RX7i, RX3i and RSTi-EP CPU Reference Manual GFK-2222AD
CPE310 versus CPU310 Performance Differences
The following differences should be considered when converting legacy applications or developing new
applications.
▪ Some exceptionally lengthy CPE backplane operations, such as MC_CamTableSelect, Data Log and
Read Event Queue functions, will take longer to complete compared to other RX3i CPU models, and
may delay backplane operations to IC695 modules.
For example, when an MC_CamTableSelect function block is executed on the PMM335 module, the
CPU’s acknowledgement of the PMM355 module interrupt may be delayed. In this situation, you may
see the following fault in the I/O Fault Table, even when the interrupt has not been dropped: Error
initiating an interrupt to the CPU.
▪ Performance specifications for many features, such as power-up time, function block execution
times and I/O module sweep times have changed. For details, refer to Appendix A.
▪ The RS-232 port on the CPE310 does not provide 5Vdc power on pin 5.
CPU305 Performance Differences vs. CPE310 and Legacy RX3i CPUs
The CPE302/CPE305 exhibits the same performance differences as listed above for the CPE310.
The CPE305 supports legacy CPU310 projects that fit within 5 Mbytes of user memory. The CPE302
supports legacy CPU310 projects that fit within 2 Mbytes of user memory. The project configuration
must be changed to support any such conversion.
Because the CPE302/CPE305 has less user memory than the other RX3i CPUs, operations that involve
transferring large files could fail.
For example, depending on the number and sizes of Data Log files already stored, the Get_DL (Get Data
Log) command could fail with a C10 hex (file transfer failure occurred while sending the data log file to
the CPU) error. To correct this error
1. Upload the data logs to Machine Edition and delete the logs from the CPU.
2. Take steps to reduce the size of the log file, such as reducing the number of samples, the sample
rate, or the number of parameters logged.

2.3.1 CPE030/CRE030 and CPE040/CRE040
Serial Ports CPE030/CRE030 & CPE040/CRE040
Each CPU has three independent, on-board serial ports, accessed by connectors on
the front of the module. COM1 and COM2 provide serial interfaces to external
devices; either can be used for firmware upgrades. The third serial port is a dedicated
Ethernet Station Manager port. For serial port pin assignments, electrical isolation
and details on serial communications, refer to Chapter 5.
Ethernet Ports CPE030/CRE030 & CPE040/CRE040
Two RJ45 ports support Ethernet communications. Refer to RX7i Embedded
Ethernet Interface for details.
Indicators CPE030/CRE030 & CPE040/CRE040
Seven CPU LEDs indicate the operating status of various CPU functions.
Two Comm LEDs indicate activity on COM1 and COM2.
