Configuration
Compatibility
Always configure sixteen bits of module status when using this module. Configuring zero bits of
module status will result in invalid data in the ESCP status bits of the module.
For new installations using AC power supplies, the CPE330 requires an IC695PSA040H or
IC695PSA140D (or higher) revision power supply to ensure compatibility.
For retrofit installations using AC power supplies, the CPE330 may require an IC695PSA040H or
IC695PSA140D (or higher) revision power supply depending on the total current load in the
backplane. If the total current load exceeds the minimum current threshold of the existing power
supply, no power supply change is required.
The CPE330 may be interchanged with a corresponding CPU320 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 or a CPE330. 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 or a
CPE330 configuration to be stored to the CPE330. When a CPE330 is configured as a CPU320,
Ethernet properties cannot be configured however, the embedded Ethernet ports may be used with
the default IP Addresses.
Migration of
CPU315 &
CPU320 Serial
Applications to
CPE330
Applications using the embedded serial ports of the CPU315 or CPU320 should move serial
functionality to the IC695CMM002 or IC695CMM004 Serial Communication Modules when migrating
to the CPE330 since it does not have embedded serial ports.
Ethernet AUP
File Support
The CPE330 does not support Advanced User Parameter (AUP) files for its Embedded Ethernet
interfaces. AUP files are supported for external IC695ETM001 Ethernet modules.

Firmware
Update
The IC695ACC402 Energy Pack automatically saves all user memory to flash when the CPE330 is
powered off, and restores it to RAM when the CPE330 is powered on. Consequently, the CPE330
does not support Service Requests 56 & 57 logic-driven Read/Write to Flash. The ENO output of the
function block returns no power flow if these service requests are executed.
When migrating a CPU320 application that uses Service Requests 56 & 57 to a CPE330, the
IC695ACC402 Energy Pack needs to be attached.
The CPE330 supports secure firmware update over Ethernet using a web browser. Supported
browsers are listed below along with the minimum required version:
 Firefox: 31.0

CIMPLICITY
OPC UA Client
CPE330 vs
CPU320 Power
Requirements
Description
When using CIMPLICITY OPC UA Client with the CPE330, ensure the total number of subscriptions
does not exceed the maximum number of subscriptions per session supported by the CPE330. (The
CPE330 supports up to 5 sessions, 7 subscriptions per session, and up to 12,500 variables.)
CIMPLICITY OPC UA Client is configured to create one subscription for every 500 items by default. If,
for example, a project contains 1000 monitored items, CIMPLICITY will create two subscriptions. The
number of items per subscription may be modified from the Device Configuration Panel
/ OPC UA DA Configuration / Subscriptions / Max. Number of Monitored Items.
When migrating a CPU320 application to a CPE330, the power consumption must be recalculated to
ensure adequate power is available in the new system. The maximum power consumption of a
CPE330 is 18W whereas the maximum consumption a CPU320 is 9.3W. Depending on the total
power available in the CPU320 system, it is possible that additional RX3i power supplies will be
required. Users may view the combined power consumption of an RX3i rack in PME by right-clicking
the power supply whose icon has a power usage indicator and selecting properties.

The only energy pack compatible with the IC695CPE330 is the IC695ACC402.
The CPE330 is not compatible with the ICRXIACCEPK01 RXi Controller Energy Pack or the
IC695ACC400 CPE305/310 Energy Pack.
 It is not physically possible to connect the CPE330 and the IC695ACC400 CPE305/310 Energy
Pack together.
 However, it is possible to connect the CPE330 and the ICRXIACCEPK01 RXi Controller Energy
Pack. Connecting the CPE330 to the RXi Energy Pack is not harmful. However, if power is
applied, the CPE330 will continuously reset and not power up. Should this occur, turn the
CPE330 off and disconnect the RXi Energy Pack.
 It is possible to connect the ICRXIACCCPK01A RXi Capacitor Pack to the IC695ACC402 Energy
Pack Base. If this occurs, the capacitor pack may take longer to charge and a battery fault may
be logged. Do not use the CPK01A RXi Capacitor Pack with the ACC402 Energy Pack Base.
 It is also physically possible to connect the IC695ACC402 CPE330 Energy Pack and
IC695ACC412 Capacitor Pack to an ICRXICTL000 controller. If this occurs no errors are logged.
However the capacitors will reach their end-of-life threshold faster than the RXi Capacitor Pack
ICRXIACCCPK01. Do not use the CPE330 Energy Pack or Capacitor Pack with the RXi Controller.

New Features and Enhancements






Initial release of the IC695CPE330 1GHz 64MB CPU w/Ethernet – The PACSystems RX3i CPE330 is a
programmable controller CPU equipped with a 1GHz dual-core microprocessor, 64Mbytes of built-in program
memory and two independent high-speed Ethernet ports. Its metal housing provides superior noise immunity. The
CPE330 is programmed and configured over Ethernet via GE’s Proficy Machine Edition (PME) software. It resides in
the RX3i main rack and supports all RX3i I/O and Intelligent Option modules.
Two Embedded Gigabit Ethernet LANs – Two independent 10/100/1000 Ethernet LANs with three autonegotiating, full-duplex 10/100/1000 Ethernet Ports allow support of two IP Addresses. LAN1 attached via a
dedicated RJ-45 connector (upper connector in Figure 1). LAN2 attaches via a pair of internally-switched RJ-45
connectors (lower connectors in Figure 1). The embedded Ethernet interface is supported by a dedicated processor
core. This significant dedicated processing capability permits the CPU to support these two LANs with:
o OPC UA Server with support for up to 5 sessions, 7 subscriptions per session, and up to 12,500 variables
o SRTP Server with support for up to 48 simultaneous connections
o Modbus/TCP Server with support for up to 16 simultaneous server connections (April 2015)
o SRTP and Modbus/TCP Client with support for up to 32 clients; each may be SRTP or Modbus/TCP (April 2015)
Battery-less User Memory Data Retention – The CPE330 preserves user memory using an energy pack without
the need to periodically replace batteries. The sole battery on each module is a user replaceable coin type battery
(5 year expected life) required to support Time-Of-Day clock operation. The conditional power-up from flash feature
works the same as previous RX3i CPUs, that is if the configuration is set to Conditional – Flash and the energy pack
is disconnected or has failed, the contents of flash will loaded into RAM at power up.
CPU315 & CPU320 Configuration Compatibility – The CPE330 may be interchanged with a corresponding CPU320
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 or a CPE330. Migration of CPU315 applications to the CPE330 is
possible with no upgrade to PME by converting them to a CPU320 application, then storing the project to the
CPE330. Versions of PME with native CPE330 support allow either a CPU320 or a CPE330 configuration to be stored
to the CPE330. When a CPE330 is configured as a CPU320, Ethernet properties cannot be configured however, the
embedded Ethernet ports may be used with the default IP Addresses.
Removable Data Storage Device (RDSD) – The CPE330 allows user programs and data to be stored to an RX3i CPU
using a USB 2.0 memory device in situations where PME software is not available at the end user’s site. OEMs can
load the folder data into a USB 2.0 memory device from a PLC which already contains the correct folder data, send
or take the device to the end user, then download that same folder data into one or more other PLCs at the end
user’s site. If a CPU320 configuration is stored to a CPE330, the USB port will be enabled to allow customers to
transfer CPU320 projects between CPE330 units without using PME. The USB port may be disabled for customers
who do not want to allow use of a USB device in their system. To disable the USB port, navigate to the CPE330 HWC
Settings tab in PME, then disable the Universal Serial Bus function. It is enabled by default.
Ethernet Firmware Update – The CPE330 supports secure firmware update over Ethernet using a web browser.

Restrictions and Open Issues
Subject
ID code
Description
Delaying more than two
minutes before initiating a
firmware download causes
web page problems when
another login is required
DE196
DE205
A delay of more than two minutes from the time login page appears and
pressing the Upload File button on the Firmware Update page will result in
the presentation of another Login page. Depending on how quickly the
login credentials are submitted, you could then see one of the following:

The upgrade page will appear and the upgrade status can be seen.

The web browser will lose connection with the CPE330 because it
automatically reset after upgrading firmware. To continue, refresh the
browser.
Running applications with
fatal faults from flash
DE86
If an application that generates a fatal fault (such as a watchdog timeout)
is stored to flash, the controller is configured to power-up from flash and
go to RUN, and the RUN/STOP switch is disabled, the application may
become stuck in an endless loop. (Power-up from flash, go to RUN,
watchdog timeout, repeat.) Return the CPE330 to the factory if this
condition is encountered. It is recommended that users thoroughly test
their application before writing it to flash.
Clear All clears PLC_BAT
and masks Energy Pack
failures
DE715
A Clear All operation clears the values of all %S bits. After this operation
the PLC_BAT status bit value may not reflect the actual status of the
Energy Pack. For example, an Energy Pack in a failed state prior to the
Clear All operation will remain in the failed state after the Clear All.
Nonetheless, the PLC_BAT bit will indicate a good state as a result of the
Clear All operation. Remove the Cap Pack and reinstall it in order to
reassert the PLC_BAT status bit.
Using OEM Passwords with
Enhanced Security
Disabled
DE755
Single character OEM passwords are not supported when enhanced
security is disabled.
PME cannot display
reference tables with
Enhanced Security Enabled
and OEM Locked
DE781
When Enhanced Security is enabled and OEM protection is engaged, only
reference areas specified within the Access Control List can be viewed by
a programmer, or HMI, regardless of privilege level. For example, if viewing
%R memory from words 1 to 400 then the Access Control List must include
read access to %R words 1 to 400. A custom reference view table with
smaller reference sizes may also be used.
Controller Communication
Window Timer settings
below 10 ms are ignored
DE845
Normal sweep allows the configuration of the Controller Communications
Window Timer for Limited operation and a time range from 0 to 255 ms
(default 10 ms). However, the system is currently ignoring settings in the 0
to 9 ms range which results in an effective window time of 10 ms for this
configuration range. This means a sweep impact of up to 10 ms may
occur for some complex Controller Communication Window operations. If
this operation is undesired then it is recommended to use a different
sweep mode such as Constant Sweep or Constant Window.
Selecting Variable Publish
State = Internal causes
variable to be published in
Address Space
DE1330
PME allows users to select a Variables Publish State to Internal. In some
cases, this will cause the variable to be published to the OPC-UA address
space. The manual states users should select External Read/Write or
External Read-Only to publish to the address space. This is the
recommended approach.

OPC-UA Server Restart
Fails to complete
DE1326
The OPC-UA server may fail to restart after a large number (~200) of
restart sequences are attempted without an intervening power cycle. A
restart sequence will occur with the following operations: Run Mode or
Stop Mode Store when published variables change and OPCUA server is
running. Whenever this occurs, the server restart bit will stay on
indefinitely. The issue is contained to OPC-UA server operation only. Power
cycling the controller is the only way to address the issue.
CPE330 Firmware Update
and IE 11.0
DE2038
CPE330 firmware may be updated using Internet Explorer 11. In rare
instances, however, it is possible that the web page may not show
firmware update status. If this occurs, wait until the CPE330 OK LED is on
solid green indicating that the firmware update is complete, then click
refresh button in IE. The web page should refresh and show the new
firmware version.
Abrupt Power-down Fault
DE2256
An Abrupt power-down detected at power-up fault is recorded in the
CPE330 PLC Fault Table if both the Logic/Configuration Power-up Source
and Data Power-up Source in the hardware configuration are set to
Always Flash or Conditional Flash and the CPE330 is turned off without an
energy pack connected. This fault indicates that user memory was not
preserved across the power cycle and does not interfere with normal
operation because the application is already configured to power up from
flash if there is no energy pack connected.
Power Supply Loss of
Module Fault After
Configuration Download
DE2257
CR-6257
A Loss of, or missing option module fault may appear for any RX3i power
supply configured in the main rack whenever a hardware configuration
download is performed after a BOC update occurs. (A BOC update occurs
during a firmware update when switching between different CPU models
in a single backlpane and also the first time a particular CPU model is
placed in a backplane. BOC updates are indicated by the RUN and Output
Enabled LEDs blinking in unison briefly during power up.)
This issue does not affect normal operation and may be cleared by power
cycling the CPU.
Missing Addition of IOC
event, when ECM850
module restarts due to
reason like reset pushbutton and SVC_REQ 24
DE1248
When ECM850 module RESET is triggered using SVC_REQ 24 or via Reset
pushbutton, PLC CPU do not report Addition of IOC fault message in
Controller fault table, after successful reset of module.
Blink Code 1-2-1-8 After
Power On
DE2017
Rarely, after powering on, the CPE330 may display blink code 1-2-1-8 on
its LEDs. If this occurs, cycle power to the CPU to clear the condition.
Loss of IO Modules in
Expansion Rack
DE2336
Rarely, IO modules in an expansion rack may fail to reconfigure if the
expansion rack is turned off and back on while the main rack remains
powered on. If this occurs, turn the expansion rack off and back on again
or, download hardware configuration using PME.
ALG616, ALG626, & ALG628
Terminal Block Present
Status Bit
DE2422
IC695ALG616-Fx, IC695ALG626-Fx, and IC695ALG628-Fx (and later
hardware revision) analog modules may not set the terminal block present
status bit in their module status after a CPE330 firmware update
completes, even if the terminal block is installed. Normal operation of the
terminal block present status bit may be restored by performing one of the
following operations: removing and reinstalling the terminal block,
resetting the analog module using Service Request #24, or power cycling
the rack.

Description
Ethernet COMMREQs not
always delivered on the
first logic sweep
ISS183540
In certain instances where User Logic is of sufficient size and a COMMREQ
is issued on first logic sweep, a race condition existing between
determination of the CPU Run/Stop state and logic-driven issuance of a
COMRREQ which may cause the COMMREQ to be aborted before its
transmission is attempted. To the user, it would appear as if the
COMMREQ was never issued. The condition is much more observable on
COMMREQs issued from the CPU’s embedded Ethernet port. To avoid the
possibility of encountering this condition, users should avoid issuing
COMMREQs on first logic sweep.
PMM335 loss is
occasionally detected on
power down of the
CPU. (Module is not lost on
power up.)
ISS182714
The PMM335 monitors power loss, independently of the CPU. The CPE305,
CPE310, CPU315, CPU320, CRU320, and CPE330 are fast enough that they
can occasionally detect and log the loss of the PMM335 just before the
CPU itself powers down.
No corrective action is required; This situation can be verified in two ways:
(1) by inspecting the timestamp in the loss-of-module report one can
correlate it with the power-down event, and (2) by performing a PME Show
Status Details report one can see that the PMM335 is present after power
up.
Hot Swapping some Analog
modules slowly result in
modules not being
recognized
CR-7365
Occasionally during a hot insertion (hot swap) of IC695 Non-Isolated
Analog Input Modules, input channels may take up to 2 seconds to reflect
actual input values after the module ok bit is enabled in the module status
word. This has only been seen when the hot insertion has been done
slowly (i.e. approximately 1.5 seconds to insert the module).
Ethernet Disconnect
During Word for Word
Change
CR-2234
If the Ethernet connection is broken during a word–for-word change, the
programmer may not allow a subsequent word-for-word change after
reconnecting due to the fact that it thinks another programmer is
currently attached. To correct the issue, go offline and then back online
again.
Simultaneous Clears,
Loads and Stores Not
Supported
CR-3118
CR-3300
Currently, PACSystems CPUs do not support multiple programmers
changing CPU contents at the same time. The programming software may
generate an error during the operation. Simultaneous loads from a single

CR-3181
If the user stores a hardware configuration to flash that sets Logic/Config
Power up Source to Always Flash or Conditional Flash and then
subsequently changes the name of the target in the programming
software, the hardware configuration will go Not Equal and will not Verify

PLC and IO Fault Tables
May Need to be Cleared
Twice to Clear Faulted
State
CR-3191
Both PLC and IO fault tables may need to be cleared to take the CPU out of
Stop/Fault mode. If one of the tables contains a recurring fault, the order
in which the tables are cleared may be significant. If the CPU is still in
Stop/Fault mode after both tables are cleared, try clearing the fault tables
again.
Setting Force On/Off by
Storing Initial Value
CR-3317
Once a force on or force off has been stored to the PLC, the user cannot
switch from force on to force off or vice-versa directly by downloading
initial values. The user can turn off the force by doing a download, and
then change the force on or off by another download.

CR-5666
As power is applied to a 90-30 High-Speed Counter, the module ready bit
in the status bits returned each sweep from the module may not be set for
as long as 20 seconds after the first PLC sweep, even though there is no
loss of module indication. I/O data exchanged with the module is not

CR-5850
Intermittently during power-up, an Informational non-critical CPU software
fault may be generated with fault extra data of 01 91 01 D6. This fault will
have no effect on the normal operation of the PLC. But, if the hardware
watchdog timer expires after this fault and before power has been cycled
again, then the outputs of I/O modules may hold their last state, rather

CR-6207
When configuring a 3rd Party Module in PME, a non-zero reference length
must be assigned to at least one reference type. For example, assign eight
bits of %I. Do not specify a length of 0 for all reference types since this will
cause the module to not function properly in the system.
Power supply status after

Sequence Store Failure
CR-6586
ISS176888
When downloading projects with very large hardware configuration or
which use large amounts of user memory, it is possible to encounter a PLC
Sequence Store Failure error when writing the project to flash. To work
around this error, either or both of the following actions may be helpful:
1. Perform an explicit clear of flash prior to performing the write.
2. Increase the operation timeout used by PME prior to performing the
write. This is done by expanding the Additional Configuration in the
Inspector window for the target controller, and adjusting the Request
Timeout. The timeout may need to be increased to as much as
60000 ms, depending on the amount of memory used and the
condition of the flash memory.

CR-6689
A configuration store operation will fail if a channel is configured for 3-wire
RTD and Lead Resistance Compensation is set to Disabled. A Loss of
Module fault will be logged in the I/O Fault table at the end of the store
operation. To recover the lost module, the configuration must be changed
to enable Lead Resistance Compensation and module must be power

ISS168431
If the Hardware Config from Target 1, with Logic/Configuration Power-up
Source and Data Source both set to Always from Flash, is stored in Flash,
then Logic and Hardware Config from Target 2, with Logic/Configuration
Power-up Source both set to Always from RAM, are stored to RAM and
there is a good battery, then when power is cycled the programmer may
show that Logic and Hardware Config are not equal. The remedy is to
clear Flash and re-store the Logic and Hardware Config from Target 2.
SRTP Connections Remain
Open After IP Address
Changed
CR-1434
The Ethernet Interface does not terminate all open SRTP connections
before changing its IP Address. Thus, once the local IP Address has
changed, the privileged connection may not be available until the SRTP
keep-alive timeout (60 sec) has expired.
Multiple Log Events
CR-2014
The Ethernet Interface sometimes generates multiple exception log events
and PLC Fault Table entries when a single error condition occurs. Under
repetitive error conditions, the exception log and/or PLC Fault Table can be
completely filled with repetitive error messages.
Spurious Ethernet Fault
CR-4104
In rare instances, after power cycle, the Ethernet Interface may log the
following fault, Event = 28H, Entry 2 = 000eH. This fault can be safely
ignored.

when IP Addresses are
not Known
If the IP Addresses of the CPE330 embedded LAN1 and LAN2 Ethernet interfaces are not
known, communication may be established using these methods to set new IP Addresses:

Set a temporary IP Address using the Set Temporary IP Address tool in Proficy Machine
Edition. (PME) After setting the temporary address, connect to the CPE330 using PME and
download a new hardware configuration with the desired permanent IP Addresses. (The IP
Address set by the Set Temporary IP Address tool is temporary and is reset to match the
stored configuration after a power cycle. After using the tool, a permanent IP Address
must be set by storing a hardware configuration.)

Connect to the CPE330 with PME using an IC695ETM001 module with a known IP Address.
Download a new hardware configuration with the desired IP Addresses for the CPE330
embedded Ethernet interfaces.
Ethernet Event Log Not
Preserved Across
Power Cycle
The CPE330 Ethernet event log for its embedded Ethernet interfaces is not maintained across a
power-cycle. Ethernet log events will be reported in the PLC Fault Table as with other RX3i
CPUs. The PLC Fault Table entries will be preserved if an energy pack is attached.
Station Manager

When deleting an OEM key from a project, you must remove the Energy Pack and cycle power
before writing to the RDSD. If this procedure is not followed there are rare occasions where
the OEM key that had been deleted may be restored on the RDSD device and therefore could
be unexpectedly downloaded to the CPU on a subsequent RDSD download.
Indirect Module
Firmware Update
This release of the CPE330 does not support indirect module firmware update via the RX3i
backplane. If a backplane module needs a firmware update, move the module to a system
using a CPE305, CPE310, or CPU320, perform the update, then move the module back to the

CPE330 Power-up Time
The CPE330 requires more time to power up than the CPU320:

When an IC695ACC402 Energy Pack is not connected, the CPE330 requires approximately
30 seconds to complete power-up. The CPU OK, RUN, and OUT EN LEDs remain off for up
to 30 seconds after power is applied.

When an energy pack is connected, the CPE330 requires up to 90 seconds to complete
power up. The power up sequence of the CPE330 begins after the energy pack is fully
charged. Charging may require up to 60 seconds depending on the capacitor pack’s initial
charge. (The energy pack’s STAT LED blinks green while it is charging and turns solid green
when charging is complete.)
Hot swap of Cap Pack
during firmware
update results in RXi
controller fatal
indication (i.e., blink
code)
Insertion or removal of the Energy Pack Cap Pack during an Energy Pack firmware update will
cause the CPE330 to become non-responsive. In order to recover from this condition user must
cycle power to the CPE330. The CPE330 controller will enter a fatal blink trap with code
0x2825.
Insertion of Cap Pack
during controller
power-up could cause
failed battery fault
If the Energy Pack is powered on without a Cap Pack and a Cap Pack is then inserted during
power-up of the CPE330, the CPE330 could log a failed battery fault. The CPE330 expects the
Energy Pack to report fully charged within a certain amount of time. This time limit may not be
met if the Cap Pack is absent at power up.
Avoid Overlapping IP
Subnets when
Configuring CPE330 IP
Address and Subnet
Mask
The CPE330 contains two LAN interfaces, each one supporting a unique IP Address. Care must
be taken when assigning IP Addresses and subnet masks to each LAN so that an overlapping
IP subnet is not created. Intermittent or no Ethernet communication may result if an
overlapping IP subnet is created and the two interfaces are NOT connected (cabled) to the
same physical network.
By default PME prohibits configuring both LAN interfaces on an overlapping IP subnet. (This
may be changed by going to Controller General Options and changing the CPE330 – LAN1,
LAN2 On Same Subnet to Show as Warning.)
Avoid Overlapping
Remote IP Networks
when Configuring
CPE330 IP Address and
Subnet Mask
The CPE330 network interface behaves like a single ETM001 with two LANs / IP Addresses. (It is
a multi-homed device.) Care must 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. Intermittent or no Ethernet communication may result if the local networks on
the CPE330 overlap a remote subnet.
CPE330 Ethernet
Gateway Operation
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:
 If a gateway is configured on only one of the two LAN interfaces and the other is not
configured (0.0.0.0) then, the single gateway is shared by both interfaces.
 If a gateway is configured on both LAN interfaces, then the LAN1 gateway is given priority
over the LAN2 gateway as long as LAN1 is functional. If, for example, the LAN1 cable is
disconnected then the CPE330 will use the LAN2 gateway as a backup.
LAN1 and LAN2 LED
Network Speed
Indicators
The LAN1 and LAN2 network speed indication LEDs embedded in the RJ-45 Ethernet ports of
the CPE330 use different colors to indicate 1 Gbps data rate. The LAN1 LED is Amber to
indicate a data rate of 1 Gbps; the LAN2 LED is Green.

Embedded Ethernet communication is managed by a dedicated processor core. Applications
using Ethernet communication should be validated to ensure adequate throughput is available
to meet the needs of the application. Additional IC695ETM001 Ethernet modules may be added
to the system if additional throughput is required.
The following apply generically to any RX3i CPU:

Loaded in Flash
WARNING: Passwords loaded to Flash (including OEM Password) cannot be cleared using clear
Flash or by downloading new firmware. Users MUST document the password as it is not
possible for the user to restore a unit to the default, no passwords condition (NULL).
OEM Protection not
enforced on power-up
from User Flash unless
engaged before power
cycle.
The OEM Protection Lock must be explicitly set before power down in order to ensure the OEM
lock will be set on power-up regardless of the type of security being used.
When passwords are
set with Enhanced
Security, connecting
with PME or
establishing SRTP
connections can cause
a temporary increase
in sweep times.
Due to the complex math involved with Enhanced Security authentication, creating SRTP
connections and changing privilege levels will take additional sweep time (several milliseconds)
not required when passwords are set with legacy security. If consistent sweep time is
important to the application, then it is recommended to configure the sweep mode for
Constant Sweep. Alternately, Constant Window or a Normal Sweep with both Limited
Backplane Window and Limited Controller Comm Windows can be configured. These sweep
modes will limit the sweep impact of Enhanced Security authentication and result in
authentication processing across multiple sweeps.
C Toolkit Application
Compatibility
Beginning with Rel 7.00 of the C Toolkit, writes to %S memory will now fail to compile where in
previous releases a compilation warning was issued. This affects use of the GE-supplied
C Toolkit macros Sw(), Si(), and Sd().
For firmware version 6.70 and later, the RUN LED for remote/expansion racks will reflect the
current IO enable/disable state (even when there are no output modules in the expansion
rack).

RUN LED for remote/expansion rack with input modules only will work as follows for All
versions prior to version 6.70:
When a remote or expansion baseplate is used with the RX3i, the RUN LED on the Series 90-30
power supply for that baseplate is illuminated when the system is in Run mode only if the rack
contains at least one output module. If the rack contains input modules only, the RUN LED is
not illuminated. This is due to the way input modules are managed in the PACSystems design
and does not indicate an error.
In Release 5.00 or later, if an attempt is made to download a C block containing undefined
symbols, the download will fail. Machine Edition will display the following message in the
Feedback Zone: Error 8097: Controller Error – Controller aborted the request [0x05][0xFF]
Prior to Release 5.00, C blocks containing undefined symbols could be successfully
downloaded, but if they were executed the CPU would transition to Stop/Halt mode.

Description
1. The A/C Power-Supply (IC695PSA040) for the RX3i is a doublewide module whose connector
is left justified as viewed when installed in a rack. It cannot be located in Slot 11 of a 12-slot
rack nor Slot 15 of a 16-slot rack. No latch mechanism is provided for the last (right-most)
slot in a rack, therefore it is not possible to place the power-supply in the second to last slot.
2. The doublewide RX3i CPUs are modules whose connector is right justified as viewed when
installed in a rack. They are referenced for configuration and by user logic applications by
the leftmost slot that it occupies. For example, if one of these modules has its physical
connector inserted in to slot 4, which means it occupies slots 3 and 4, the CPU is referenced
as being located in slot 3. The referenced location of the CPU is not determined by what slot
the physical connector is located in, but rather by the left most slot occupied by the entire
module.
3. Due to item #2 above, a doublewide RX3i CPU may be located in Slot 0 of a rack (physical
connector in Slot 1). In addition the CPU cannot be located in Slot 11 of a 12-slot rack nor Slot
15 of a 16-slot rack, since doing so would require the physical connector to be located in the
slot reserved for an expansion module.
4. When migrating a Series 90-30 CPU system to a PACSystems RX3i CPU, be aware that to
maintain the Slot 1 location of the CPU, only a singlewide power-supply may be used in Slot
0. Either DC power supply can be used (IC695PSD040 or IC695PSD140). Therefore, if the
application using an existing Series 90-30 system must maintain a Slot 1 CPU and uses an
AC power-supply, the RX3i system must have the RX3i AC power-supply located in a slot to
the right of the RX3i CPU in Slot 1.
5. In deciding to place the CPU in slots other than Slot 1, the user should be aware of the
possible application migration issues that could arise. The following lists the areas that could
be affected when migrating an application from one CPU slot to another.

External
Devices
Item Affected
Service Request #15
(Read Last-Logged Fault
Table Entry)
Service Request #20
(Read Fault Tables)
Communications Request
(COMMREQ)
How Affected
Location of CPU faults will not be the standard 0.1
location, but will reflect the slot the CPU is located in. User
logic that decodes fault table entries retrieved by these
service requests may need updating.
COMMREQs directed to the CPU (e.g. those directed to the
serial ports of the CPU) will need to be updated with the
correct CPU slot reference.
CPU Slot location
Slot location of the CPU must be updated in the HW
Configuration to reflect the CPU’s true location.
Faults logged for the CPU
The location of faults logged for the CPU in the fault table
will not be the standard 0.1 (rack.slot) location, but will
reflect the CPU’s actual slot.
Series 90 PLCs
Remote Series 90 PLCs that use SRTP Channels COMMREQs expect the CPU to be in slot
1. In order to support communications with Series 90 SRTP clients such as Series 90
PLCs using SRTP Channels, the RX3i internally redirects incoming SRTP requests
destined for {rack 0, slot 1} to {rack 0, slot 2}, provided that the CPU is located in rack 0
slot 2 (and the remote client has not issued an SRTP Destination service on the
connection to discover the rack and slot of the CPU). This special redirection permits
Series 90-30 applications that expect the power supply to be located leftmost and the
CPU to be located to the right of the power supply to function. Attempts to establish
channels with CPUs in slots other than 1 or 2 will fail if initiated from Series 90 PLCs.
HMI and External Communication Devices
All external communication devices that interact with the CPU should be checked for
compatibility with CPU slot locations other than slot 1. Problems may arise with, but are
not limited to, initial connection sequences and fault reporting. Machine Edition View
customers should select GE SRTP as their communications driver – it can communicate
with a CPU in any slot.
Host Communications Toolkit (HCT)
Applications that utilize the Host Communications Toolkit may require updated drivers.

Logic Executed in Row
Major Instead of
Column Major
Logic execution in PACSystems RX3i is performed in row major order (similar to the Series 9030). This is different from the Series 90-70 that executes in column major order. This means
that some complicated rungs may execute slightly differently on PACSystems RX3i and Series
90-70. For specific examples, see the programming software on-line help.
NaN Handled
Differently Than in
S90-30
The PACSystems RX3i CPU may return slightly different values for Not A Number as compared
to Series 90-30 CPUs. In these exception cases (e.g., 0.0/0.0), power flow out of the function
block is identical to Series 90-30 operation and the computed value is still Not A Number.
PID Algorithm
Improved
The PID algorithm used in PACSystems has been improved and therefore PID will function
slightly differently on PACSystems RX3i than on the Series 90-30. The differences are that the
elapsed time is computed in 100 μS instead of 10 mS units. This smoothes the output
characteristic, eliminating periodic adjustments that occurred when the remainder
accumulated to 10mS.
Also, previous non-linear behavior when the integral gain is changed from some value to 1
repeat/second was eliminated.
 Service Requests 6, 15, and 23 have slightly different parameters. Refer to PACSystems
RX7i & RX3i CPU Programmer's Reference Manual, GFK-2950.
 PACSystems PLCs support Service Request 26/30 functionality via fault locating
references.
 Service Request 13 requires a valid value in the input parameter block (Refer to
PACSystems RX7i & RX3i CPU Programmer's Reference Manual, GFK-2950 for details). On
the Series 90-30 and Series 90-70 the parameter block value was ignored.
 Service Requests 48 and 49 are no longer supported (there is no auto-restart) because
most faults can be configured to be not fatal.
IL and SFC are not available.
Some Service Requests

DO I/O Instruction
The Series 90-30 Enhanced DO I/O instruction is converted to a standard DO I/O instruction

END Instruction
The Series 90-30 END instruction is not supported. Alternate programming techniques should
be used.
Non-nested JUMP,
LABEL, MCR, &
ENDMCR Instructions
Non-nested JUMPs, LABELs, MCRs, & ENDMCRs are translated to the corresponding nested
JUMPs, LABELs, MCRs, & ENDMCRs when converting from Series 90-30 to PACSystems RX3i.
Changing IP Address of
Ethernet Interface
While Connected
Storing a hardware configuration with a new IP Address to the RX3i while connected via
Ethernet will succeed, then immediately disconnect because the RX3i is now using a different
IP Address than the Programmer. You must enter a new IP Address in the Target Properties in
the Machine Edition Inspector window before reconnecting.
Timer Operation
Care should be taken when timers (ONDTR, TMR, and OFDTR) are used in program blocks that
are NOT called every sweep. The timers accumulate time across calls to the sub-block unless
they are reset. This means that they function like timers operating in a program with a much
slower sweep than the timers in the main program block. For program blocks that are inactive
for large periods of time, the timers should be programmed in such a manner as to account for
this catch up feature.
Related to this are timers that are skipped because of the use of the JUMP instruction. Timers
that are skipped will NOT catch up and will therefore not accumulate time in the same manner
as if they were executed every sweep.
Constant Sweep
Constant Sweep time, when used, should be set at least 10 ms greater than the normal sweep
time to avoid any over-sweep conditions when monitoring or performing on-line changes with
the programmer. Window completion faults will occur if the constant sweep setting is not high
enough.

Large Number of
COMMREQs Sent to
Module in One Sweep
Causes Faults
Description
A large number of COMMREQs (typically greater than 8) sent to a given board in the same

MOD_OTHR_SOFTWR (16t, 10h) and the error code is COMMREQ_MB_FULL_START (2). When
this occurs, the FT output of the function block will also be set. To prevent this situation,
COMMREQs issued to a given board should be spread across multiple sweeps so that only a
limited number (typically 8 or less) of COMMREQs are sent to a given board in each sweep. In
addition, the FT output parameter should be checked for errors. If the FT output is set (meaning
an error has been detected), the COMMREQ could be re-issued by the application logic.
C Block Standard Math
Functions Do Not Set
errno
In C Blocks, standard math functions (e.g. sqrt, pow, asin, acos) do not set errno to the correct
value and do not return the correct value if an invalid input is provided.
Hot Swap
Hot Swap of power supplies or CPUs is not supported
Run Mode Store of EGD
RX3i peripheral Ethernet modules (IC695ETM001) must be running firmware version 6.00 or
greater to utilize the Run Mode Store of EGD feature.
Proper IP Addressing is
Always Essential
The PACSystems Ethernet Interface must be configured with the correct IP Address for proper
operation in a TCP/IP Ethernet network. Use of incorrect IP Addresses can disrupt network
operation for the PACSystems and other nodes on the network. Refer to PACSystems RX7i &
RX3i TCP/IP Ethernet Communications User Manual, GFK-2224 for important information on
IP Addressing. When storing a new HW configuration to the RX3i, be sure that the HW
configuration contains the proper Ethernet addressing data (IP Address, Subnet Mask, and
Gateway IP Address) for the RX3i.
Note: Machine Edition programming software maintains the target IP Address (used to
connect the programmer to the target) independent of the contents of the HW Configuration
for that target). The target IP Address is set in the Target Properties in the Machine Edition
Inspector window. Storing a HW Configuration whose Ethernet addressing data contains an IP
Address that is different from the RX3i target IP Address will change the IP Address used by the
target RX3i as soon as the Store operation is completed; this will break the Programmer
connection. Before attempting to reconnect the Programmer, you must change the target IP
Address in the Target Properties in the Machine Edition Inspector window to use the new IP
Address. To regain communication at the former IP Address, use the manual corrective action
described above.
Storing a HW Configuration containing an incorrect Ethernet addressing data to the
PACSystems RX3i will result in loss of the Programmer connection and will require manual
corrective action as described above.
Network Architecture
and Overload
The hub or switch connections in an Ethernet network must form a tree and not a ring;
otherwise duplication of packets and network overload may result. In this situation, the RX3i
Ethernet modules will continually reset.
Caution
The hub or switch connections in an Ethernet network must form a
tree and not a ring; otherwise duplication of packets and network
overload may result
Reporting of Duplicate
IP Address
The PACSystems RX3i does not log an exception or a fault in the PLC Fault Table when it
detects a duplicate IP Address on the network.
SRTP Connections
Remain Open After IP
Address Changed
The Ethernet Interface does not terminate all open SRTP connections before changing its
IP Address. Once the local IP Address has changed, any existing open TCP connections are
unable to normally terminate. This can leave SRTP connections open until their underlying TCP
connections time out.

Description
Send Information Report COMMREQ requests with a minimum interval between host accesses
of 200 ms or less may fail if issued from the CPU’s embedded Ethernet port. A COMMREQ
Status Word value of 0290H, Period expired before transfer completed; still waiting on transfer
indicates this condition occurred. To work around this issue, the user can set the minimum
interval between host accesses to a value greater than 200 ms if issuing a Send Information
Report COMMREQ from the CPU’s embedded Ethernet port.
Modbus/TCP Client
Channels require at
least a 10 ms delay
between bulk channel
close and bulk channel
open processing
On CPUs with embedded Ethernet ports, a delay of at least 10 ms must occur between logicdriven attempts to close sixteen Modbus/TCP Channels simultaneously and then re-open
sixteen Modbus/TCP Channels. This delay is necessary to provide external Modbus/TCP
Servers sufficient time to close all channels before the Client issues channel open requests.
Lengthy CPE Backplane
Operations
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.
The program name for PACSystems is always LDPROG1. When another program name is used
in a COMMREQ accessing %L memory, an Invalid Block Name (05D5) error is generated.

Scansets on the master do not work properly for the first operation of the scanset after

After downloading a new hardware configuration and logic, a power cycle may be required to
resume FANUC I/O operation.
Use PLCs of similar performance in FANUC I/O networks. If a master or slave is located in an
RX3i system, the other PLCs should be RX3is or Series 90-30 CPU374s.
Repeated power up/down cycles of an expansion rack containing FANUC I/O slaves may result
in failure of the slaves’ operation, with the RDY LED off.
The Serial IO Processor (IC693APU305) will lose the first count after every power up or every
time the module receives a config
In previous releases, the CPU allowed configuration of COMMREQ Status Words in bit memory
types on a non-byte-aligned boundary. Even though the given reference was not byte-aligned,
the firmware would adjust it the next-lowest byte boundary before updating status bits,
overwriting the bits between the alignment boundary and specified location. To ensure that
the application operates as expected, release 3.50 requires configuration of COMMREQ Status
Words in bit memory types to be byte-aligned. For example if the user specified status bit
location of %I3, the CPU aligns the status bit location at %I1. Release 3.50 firmware requires
the user to specify the appropriate aligned address (%I1) to ensure that the utilized location is
appropriate for their application. Note that the actual reference location utilized is not
changed, but now is explicitly stated for the user.

Description
The PACSystems CPU receives requests to change between stop and run mode from many
different sources. These include (but are not limited to) Proficy Machine Edition, HMIs, the user
application, and the RUN/STOP switch. Since there are many potential sources for a mode
change request, it is possible to receive a new mode change request while another is already
in progress. When this scenario occurs, the CPU evaluates the priority of the new mode
change request with the mode change that is in progress. If the new mode change request
has an equal or higher priority than the one already in progress, the CPU transitions to the new
mode instead of the one in progress. If, however, the new mode change request has a lower
priority than the one in progress, the new mode request is discarded and the CPU completes
the mode change that is in progress. The sweep mode priorities are (listed from highest to
lowest priority) STOP HALT, STOP FAULT, STOP, and RUN. (NOTE: The IO ENABLED/DISABLED
state is not part of the mode priority evaluation.) For example, a CPU is in RUN IO ENABLED
mode and a Service request 13 function block is executed to place the CPU into STOP IO
DISABLED mode. Before the transition to STOP IO DISABLED is completed, the RUN/STOP switch
is changed from RUN IO ENABLED to RUN IO DISABLED. In this case, the CPU ignores the new
request from the RUN/STOP switch to go to RUN IO DISABLED mode because it is already
processing a request to go to STOP IO DISABLED mode and STOP mode has a higher priority
than RUN mode.
In a 9070 the SUSPEND_IO function block suspends EGD in addition to IO Scan. In PACSystems
controllers the SUSPEND IO only suspends IO Scan.
If a power supply is missing or has some fault that makes it appear to be missing, the CPU may
improperly report (upon download of configuration) more than one fault. Such additional
faults may be safely ignored and will not occur in a properly configured rack (with no
mismatches or missing modules),
Controller Supplemental Files uploaded from the CPU are time stamped as 8/1/1980 12:08AM
regardless of PC or PLC time.
