Description
Run Mode Store (RMS) to User
Flash
Enables the user to make logic changes while in run mode that will be saved to both User
RAM and Flash. User RAM and User Flash equality will be maintained.
SVC_REQ 63 Logic Driven Data
Write to Non-Volatile Storage
Allows logic to write up to four regions of %R, %AI, or %AQ data to non-volatile storage
up to 24 times in a 24-hour period. The data is reloaded to the data tables on power up.
•%S53: #LG_CFG_SRC_RAM
•%S54 #DATA_SRC_RAM
•%S55: #DATA_SRC_NV
•Set to 1 if CPU logic and HWC is retrieved from User RAM at powerup.
•Set to 1 if the CPU reference data is retrieved from User RAM at powerup.
•Set to 1 if the CPU reference data is retrieved from any SVC_REQ 63 NV Storage
locations at powerup.
Audit Trail
The CPU contains a log of user actions performed on the PLC. PACAnalyzer is used to
retrieve the Audit Trail log. The log records events like web page connection,
configuration download, STOP/RUN transition, clearing of fault tables, etc.

https://www.emerson.com/Industrial-Automation-Controls/Support.
Release in line with software license compliance requirements.
PACSystems CPU Upgrade
The RX3i firmware upgrade process may take up to four minutes to complete, depending on the contents
of the update. During the update, the RUN and OUTPUTS ENABLED LEDs blink GREEN in unison and the
CPE400 / CPL410 may automatically reset one or more times. All LEDs will be off during the automatic
reset. The IC695ACC403 Energy Pack (if present) may also be updated. The energy pack blinks all LEDs
GREEN and performs an automatic reset following its update.
Note: Do not manually power cycle the CPE400 / CPL410 or remove the energy pack (if present) or the cap
pack from the energy pack base during the updates as this may place the CPU and energy pack in an
unrecoverable and unusable state.

Hot Standby
Redundancy
CPE400 firmware release 9.30 and CPL410 release 9.55 support Hot Standby Redundancy
with PROFINET IO. Hot Standby Redundancy with Genius IO is supported using the
IC695GCG001 RX3i Genius Communications Gateway. Hot Standby Redundancy with
Ethernet Global Data (EGD) is not supported.
LAN3 restriction
LAN3 is used only to synchronize the Primary and Secondary CPUs in a Hot Standby
Redundancy configuration. No additional hardware may be attached to LAN3. Use of
both ports is recommended when used in this fashion, as this provides a redundant
synchronization link between the two CPUs.
Redundant IP Support
CPE400 firmware release 9.30 and CPL410 release 9.55 support two independent
Redundant IP addresses, one for LAN 1 and one for LAN 2. LAN 2 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.
Ethernet AUP File
Support
The CPE400 and CPL410 do not support Advanced User Parameter (AUP) files for their
Embedded Ethernet interfaces. Instead, use PAC Machine Edition to set the Ethernet
configuration parameters for SNTP and advanced Ethernet Global Data applications.

GFK-3003AA May 2023

Compatibility Issue
Description
Service Request 56 & 57
Logic Driven
Read/Write to Flash
Support
The IC695ACC403 Energy Pack automatically saves user memory to nonvolatile storage
when the CPE400/CPL410 is powered off and restores it to RAM when the
CPE400/CPL410 is turned on. Consequently, the CPE400 and CPL410 do not support
Service Requests 56 & 57 Logic Driven Read/Write to Flash. The service request function
block’s ENO output returns no power flow if these service requests are executed.
Whenever an RX3i application that uses service requests 56 & 57 is being migrated to a
CPE400 or CPL410, an IC695ACC403 Energy Pack should be used to provide equivalent
functionality, since the service requests themselves will have no effect and should ideally
be removed.
HART®Pass Through
CPE400 supports HART pass-through. HART Pass Through entails the usage of PC-based
applications, RX3i Analog modules with HART functionality, and (optionally) supporting
PROFINET products. HART Pass Through operation is described in the PACSystems HART

conditions Do not use the CPE400 Energy Pack or Capacitor Pack with the
RXi Controller.
•It is physically possible to connect the IC695ACC403 CPE400/CPL410 Energy Pack
to an IC695CPE330 controller. If this occurs, no errors are logged. However, it
will not allow any future firmware updates to the ACC403 Energy Pack. Do not
use the ACC403 Energy Pack with the RX3i CPE330 Controller.
•It is physically possible to connect the IC695ACC402 CPE330 Energy Pack and
IC695ACC412 Capacitor Pack to an IC695CPE400 or CPL410 controller. If this
occurs no errors are logged. However, it will not allow any future firmware
updates to the ACC402 and the capacitors will reach their end-of-life threshold
faster than the RX3i Capacitor Pack IC695ACC413. Do not use the ACC402
Energy Pack or ACC412 Capacitor Pack with the RX3i CPE400 or CPL410
Controller.
•It is physically possible to connect the ICRXIACCEPK01A RXi Energy Pack to an
IC695CPE400 or CPL410 controller. If this occurs no errors are logged. However,
it will not allow any future firmware updates to the EPK01A and user memory
may not be preserved under all conditions. Do not use the EPK01A RXi Energy
Pack with the RX3i CPE400 or CPL410 Controller.
Ethernet Station
Manager Compatibility
Ethernet Station Manager Utility Version 1.3 Build 2 or later is recommended for use with
the CPE400 and CPL410. Earlier versions are compatible; however, they may not display
all the Ethernet parameters after issuing a parm all command. Should this issue occur,
pressing enter, or issuing another command will cause the station manager to display
the remaining parameters.
Set Temporary IP
Address not supported
Since the configured IP Addresses may be viewed using the CPE400/CPL410 OLED
display, the Set Temporary IP Address tool in PME is not required for CPE400/CPL410 and
is therefore not supported for CPE400 and CPL410.

Supported Primary and
Secondary CPUs
The Primary and Secondary CPUs in a redundant system must be the same model. For
example, two CPE400s may be paired together as the Primary and Secondary CPUs.
Likewise, two CPL410s may be paired together. Pairing CPE400 and CPL410 as Primary
and Secondary CPUs in a redundant system is not permitted.
Display Port is not
operational
The Display port, located on the underside of the CPE400 and CPL410 is not operational.
USB Ports
The CPE400’s left USB port is assigned to PACEdge. The right USB port is reserved.
The CPL410’s left USB port is assigned to PACEdge. The right USB port is reserved.
Micro SD Card
The Micro SD Card Slot is reserved and not available for use.
Serial IO Protocol
Serial IO Protocol is supported on the CPE400 effective with firmware release 9.40 and
the CPL410 effective with release 9.55.
Cimplicity and RX3i
Subscription Size
Incompatibility
The RX3i OPC UA server supports up to 10 subscriptions with up to 12,500 monitored
items each. Cimplicity OPC UA driver supports an unlimited number of subscriptions with
a default limit of 500 monitored items per subscription, and a hard limit of 32,767 bits of
data in a subscription. This means that it is not possible to subscribe to all 12,500
variables of the RX3i PLC with a Cimplicity HMI. The effective monitored item limit in
Cimplicity is dependent on the size of the data being subscribed to. Other OPC UA clients
with a larger monitored item per subscription limit can subscribe to the entire address
space of variables, such as UA Expert.
Network and Memory

DE196
DE205
DE2626
The CPU enforces a 2-minute login activity timeout on the Firmware Update
web page. Selecting an update package on the Firmware Update page and
pressing the Upload File button after the timer expires initiates a firmware
update. However, instead of displaying the firmware update status, one of
these scenarios may occur:
•Another login page is presented. After entering the user name and
password the update status is displayed.
•The web browser loses connection with the CPE400 and is unable
to display the update status because the CPU is automatically
resetting while applying the firmware update. After the reset
completes, pressing the refresh button in the browser shows the
installed firmware version.
•An error message is displayed indicating the firmware update was
not successful however, returning to the firmware update home
page shows that the new firmware version was installed.
These timeout issues may be avoided by having the firmware file ready so
that the firmware update can be initiated immediately after logging in.
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.) It is recommended that users thoroughly test their
application before writing it to flash and disabling the RUN/STOP switch.
RX3i CPUs that experience this issue must be returned to Emerson
Automation Solutions for repair.

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.
Dual Hardware
Configuration Not
Created When
Uploading Redundant
CPE400/CPL410
Application
DE3052
A dual hardware configuration is not automatically created in PME when
uploading a redundant CPE400/CPL410 application. Before uploading the
primary application, dual hardware configuration must be manually
enabled by setting the CPE400 or CPL410’s Enable Redundancy target
property to True. The secondary application may then be uploaded.
Memory Not Preserved
After Turning
CPE400/CPL410 Off
with Power Button
DE3975
The CPE400 and CPL410 do not preserve user memory when the Power
Button is used to turn the CPU off while an energy pack is connected. At
this time, it is recommended to turn off power to the circuit powering
either the CPE400 / CPL410 or its associated Energy Pack to allow for
orderly shutdown procedures to occur.
Multibit ECC Memory
Error Causes Hardware
Watchdog
DE4181
The CPE400 and CPL410’s hardware watchdog timer expires and the CPU
reboots into STOP HALT mode if an uncorrectable (multi-bit) ECC memory
error is detected. Correctable (single-bit) errors are automatically repaired
as expected. No ECC memory faults are logged in the fault table whenever
either occurs.
Sequence Store Failure
Downloading
Redundant Hardware
Configuration
DE4254
It is possible to download a redundant hardware configuration with a non-
zero %W transfer list length to a CPE400 or CPL410 which has no %W
memory configured. The downloaded configuration is not valid since no
%W memory is configured, so none should be allowed in the transfer list.
If this occurs, the CPU enters STOP / FAULT Mode and a Sequence Store
Failure is listed in the PLC Fault Table. PAC Machine Edition’s Feedback Zone
shows Error 8097: Controller Error - Controller program reference exceeds
configured reference [0x05][0x90] [0x80310015]
This issue may be resolved by correcting the hardware configuration to
either remove %W memory from the transfer list or allocate %W memory in
the CPU corresponding to the length configured in the transfer list. Once
corrected, place the CPE400 or CPL410 into STOP / NOIO Mode by clearing
the PLC Fault Table and downloading the hardware configuration again.

DE5687
SRTP and Modbus TCP Client COMMREQs may require multiple TCP retries
to establish a connection when a gateway is configured on both LAN 1 and
LAN 2. Once a TCP connection is established, client operations proceed
normally. Client communications occur without multiple retries if only one
of the LANs has a gateway configured or if there are no gateways
configured.
PLC Fault Table Empty
After Restart Due to
Fatal Error
DE6573
PAC Machine Edition may not display any faults in the PLC fault table if it is
connected to a controller when it encounters a fatal error that results in an
automatic restart. (STOP/HALT) Should this occur, the fault table is empty
and the PME Fault Table Viewer indicates zero faults out of X number of
faults displayed. (EX: Displaying 0 of 11 faults, 11 Overflowed) Closing and
re-opening the PME Fault Table View displays the faults correctly.
PLC Fault Table Faults
Not Shown in
Chronological Order
DE6574
Faults in the PLC Fault Table may not be listed in chronological
order following an automatic controller restart due to a fatal error.
PME Error Programmer
already attached
DE8016
When connected to a target, there is a field called the request timeout,
which can be up to 240s. If you are connected to PME via a LAN2 port, and
you remove the ethernet cable and then re-attach it to a LAN2 port,
reconnect to PME, and try to enter programmer mode, the operation will
fail. To enter programmer mode, you must wait for the request timeout
amount of time to be able to enter programmer mode. You will see the
following error in PME when trying to enter the programmer before the
request timeout has expired:
Error 8085: Programmer already attached [{PC name}\{user name}]
To recover, you can wait for the request timeout amount of time, or you
can restart the PLC.
To avoid this issue, make sure you press "Disconnect" before removing the
ethernet cable from the LAN2 port, or else, you will have to wait for the
configured request timeout before you can re-enter the programmer
mode.

DE8313
The OPC UA Server in PACSystems controllers with firmware versions 10.10
and later, on controllers that are configured for OPC UA Non-Transparent
Redundancy (IC695CPE330, IC695CPE400, and IC695CPL410) and in a
redundant server pair, do not populate the information necessary to
automatically connect to the remote OPC UA server using the built-in OPC
UA FindServers service. If configuring an OPC UA Client for Non-
Transparent Redundancy to communicate with the PACSystems OPC UA
servers on a redundant system, the DiscoveryURLs for both servers must
manually be configured into the OPC UA Client. The default method of
configuration with Cimplicity software is to manually configure both
DiscoveryURLs for local and remote redundant servers and is not impacted
by this defect. Some OPC UA clients may not offer manual configuration of
both DiscoveryURLs and will have a compatibility issue when configuring
for OPC UA Non-Transparent Redundancy with a PACSystems OPC UA
server.
Failure To Publish All
Expected Variables to
OPC UA Address Space
DE9888
SFDC02016
781
Variables with their "Publish" property set to "Internal" are incorrectly
counted against the CPU's OPC UA address space limit but not actually
published. This causes some variables with their "Publish" property set to
"External Read/Write" or "External Read-Only" to not be present the OPC
UA address space. If variables do not have their "Publish" property set to
"Internal", or if an internally published variable comes alphabetically after
any externally published variables, then this issue does not occur.

DE9900
In the OPC UA address space folder "Application Information" the "Address

If the PLC Clock is set to a day prior to the year 2010, the OPC UA server will
negotiate session timeouts during session creation, but if the attached OPC
UA client stops responding to the OPC UA protocol the session timeout will
not be enforced, consuming a session incorrectly. Restarting the OPC UA
server will reclaim the abandoned sessions. If the PLC clock is set to any
date in the year 2010 or later, including the correct time/date, the problem
will not occur.

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 the first logic sweep, a race condition exists between the
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 the
first logic sweep.
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 since 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
PLC are allowed.
Hardware
Configuration Not
Equal After Changing
Target Name
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 as equal.
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 in 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 Force Off by another download.
Second programmer

Description
Do not attempt to store
logic and configuration
to a PLC from multiple
targets
CR-6450
In a system in which the hardware configuration is stored from one target
and logic is stored from a different target, powering up from flash will not
work. The observed behavior is that, following a power-up from flash, PME
reports hardware configuration and logic are not equal.
Sequence Store Failure
CR-6586
ISS176888
When downloading projects with very large hardware configurations 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 before performing the write.
2. Increase the operation timeout used by PME before 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.
C Toolkit PlcMemCopy
Documentation
Incorrect
CR-7082
This routine does allow the destination and source pointers to be outside of
reference memory. If the destination points to discrete reference memory,
overrides and transitions will be honored. Note that the header for
PlcMemCopy has been updated in Release 3.50 of the C toolkit.
Logic and HWC are not
equal after the power
cycle
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.
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
filled with repetitive error messages.
Spurious Ethernet Fault
CR-4104
In rare instances, after the power cycle, the Ethernet Interface may log the
following fault, Event = 28H, Entry 2 = 000eH. This fault can be safely
ignored.
Clear of large hardware
configurations may
cause log event 08/20
CR-6577
A Log event 08/20 may occur when very large hardware configurations are
cleared, and transfers are active on other Server connections. This log
event can be safely ignored.
PLC response timeout
errors (8/08) in Ethernet
exception log under
extremely heavy SRTP
traffic
ISS010006
Under extremely heavy SRTP traffic conditions, the Ethernet Interface may
log an event in the Ethernet exception log (Event 8, Entry 2 = 08H)
indicating an overload condition. This error terminates the SRTP
connection. If this event appears, either the traffic load should be reduced,
or the application should use an alternate communications method to
verify that critical data transfers were not lost due to the overload.
