PACSystems™ RX7i CPUs
IC698CPE010-EJ (300 MHz), CPU Firmware Version 3.11
IC698CPE020-EJ (700 MHz), CPU Firmware Version 3.11
Release 3.11 of the RX7i CPU fixes the following issues:
In earlier versions, EGD continues to produce exchanges when the CPU is in a STOP-HALT condition.
In version 3.11, Ethernet Global Data (EGD) will stop producing exchanges when the CPU enters a
STOP-HALT condition.
In earlier versions, if the user did not supply a value for the Bit value parameter (B1) of the SHIFT-LEFT
and SHIFT-RIGHT functions, this parameter was not initialized. In version 3.11, if the user does not
provide a value for the Bit Value parameter (B1) the Bit value used will be 0.
For additional information, see “Problems Resolved by Version 3.11” on page 6.
This update applies only to the CPU firmware. The current Ethernet firmware version remains 3.00.

SRTP and EGD Performance
Differs from Series 90-70
SRTP and EGD performance in the RX7i differs slightly from the Series 90-70. Each
RX7i Ethernet Interface supports a greater number of SRTP connections and EGD
exchanges.
Please also note that the RX7i currently has several SRTP and EGD operational
restrictions when compared to the Series 90-70. When migrating Series 90-70 Ethernet
applications to the RX7i, please carefully read the "Ethernet Operational Notes” section
on page 20.
Series 90-70 LAN Interface
Modules (IC697CMM741 and
IC697CMM742) not Supported
by RX7i
Please note that the Series 90-70 LAN Interface Modules (IC697CMM741 and
IC697CMM742) are not supported by the RX7i and should not be placed in an RX7i
rack. The RX7i CPU contains an embedded Ethernet Interface. If additional Ethernet
Interfaces are required, the RX7i Ethernet Module (IC698ETM001) should be used.

CPU Problems Resolved by Version 3.11
Subject
Description
EGD continues to produce when
the CPU is in STOP-HALT
mode.
In earlier versions, EGD continues to produce exchanges when the CPU is in a
STOP-HALT condition. This problem has been corrected in version 3.11 so that
EGD production stops when the CPU is in STOP-HALT.
As of release 3.11 when the CPU goes to STOP-HALT (error sweep), the
hardware watchdog timer is tripped and the CPU will be unresponsive. The CPU
should be power cycled to recover. In most cases the fault table will be preserved
when power cycled with a battery.
Bit Value parameter for ShiftRight and Shift-Left function
blocks not initialized.
In earlier versions, if the user does not provide an input value for the Bit value
parameter (B1), the value used for the shift would be random (0 or 1).
There is no problem when a value is specified for theB1 parameter.
This problem has been corrected so that, if a value is not specified for B1, a 0 will
be shifted into the resulting open bits.
Ethernet Problems Resolved by Version 3.00
Subject
Description
IO Fault Table Web Page
Display Problem
The I/O Fault Table web page now displays correct values for various parameters such as
I/O Bus, and Bus Point.
IO Fault Table Web Page
Restriction
The I/O Fault Table web page now supports the field of ‘fault description’.
%L on Reference Table Web
Page
%L data is now displayed on reference table web page.
Javascript Error
The following Javascript error is no longer seen when accessing the I/O and PLC Fault
Table web pages using Internet Explorer: “ ‘self.document.reform.log_textbox’ is null or
not an object”
SNTP Error Logged When Not
Configured
The Ethernet Interface no longer logs an SNTP event in the Ethernet exception log (Event
= 29H, Entry 2 = 01H) even though Ethernet time synchronization is configured as None
instead of SNTP.
Station Manager “EGDCMD
st” May Report Incorrect Data
The EGD sample due time and EGD exchange state as reported by the “EGDCMD st”
command are now accurate.
Avoid Too-rapid ARP Cache
Flushing
The Advanced User Parameter “fflush” can now be set lower than 5 seconds (down to 1
second).
Older Network Devices And
Nuisance Faults
The Ethernet interface no longer gives nuisance faults when connected to certain network
devices, specifically those hubs that do not complete speed negotiation in 500 ms or less.
“Internal Error” Exception
when Duplicate EGD Producer
IDS
An exception (Entry = 28, Entry 2= 24) will no longer appear in the exception log if there is
another EGD producer on the network using the same Producer ID as the Ethernet
interface.
EGD Tally Inconsistency
The EGD consumption transfer tally “DataRx” no longer increments if the incoming EGD
message is discarded due to signature mismatch.
Blink Code “2-8” on Ethernet
Interface After Multiple Rapid
Power Cycles
The Ethernet Interface no longer displays a blink code of “2-8” after rapid multiple power
cycles. Resetting the Ethernet Interface returned it to normal operation.
Don’t “Loopback” EGD
The loopback IP address 127.0.0.1 may now be used to produce and consume EGD.
Incorrect COMMREQ Status
Word for Invalid Read
Exchange EGD command
When an EGD Read Exchange command references out-of-range local PLC reference
memory, the Ethernet interface now returns COMMREQ status word 9085H and does not
write any data to local PLC reference memory, as would be expected.
Incorrect Value in SRTP Error
PDU Message
When the SRTP Server detects an internal SRTP processing the SRTP Destinations
response, it now inserts a correct error code value into the resulting SRTP Error PDU
message (i.e. the internal SRTP error value is now less than 40 (= 28H)).

New Ethernet Features and Enhancements (Version 3.00)
Release 3.00 of the RX7i Ethernet interfaces provides the following features and enhancements.
Support for up to 32 SRTP Channels:
SRTP (Client) Channels provides communication from PLC to PLC, or from the PLC to a host application
SRTP server, over an Ethernet Network using the SRTP/TCP/IP protocol.
Up to 80 SRTP/TCP connections total, consisting of up to 48 SRTP Server connections and up to 32 Client
Channels.
PACSystems Ethernet Interfaces support the same set of Channel commands as Series 90 Ethernet
Interfaces, and use identical Command Block formats. Please refer to the PACSystems TCP/IP Ethernet
Communications Manual, GFK-2224C or later) for details. Note that specifying a Remote PLC or Host
Application SRTP Server by name is not supported in PACSystems. The Channel Commands are:
Establish Read Channel (2003). Requests that a channel be established between the Local
PLC (client) and a Remote PLC (server) and that data be read from the Remote PLC and
transferred to the Local PLC.
Establish Write Channel (2004). Requests that a channel be established between the
Local PLC and a Remote PLC and that data from the Local PLC be transferred to the
Remote PLC (read from the client and written to the server).
Send Information Report (2010). Requests that a specified block of memory within the
Local PLC be transferred to a Host Application SRTP Server (rather than a Remote PLC).
Abort Channel (2001). This is a local command: communication occurs only between the
Local PLC and the local Ethernet Interface. It requests that the Ethernet interface stop and
disconnect a specific channel from the Remote PLC. The interface also allows for a way to
specify all channels be aborted.
Retrieve Detailed Channel Status (2002). This is a local command: communication occurs
only between the Local PLC and the local Ethernet Interface. It requests that the current
Detailed Channel Status Data (DCSD) words be returned for the specified channel number.
The DCSD consists of two words that contain the last channel status codes that occurred
and an active/inactive channel indicator.
Support for Modbus/TCP Server
Supports Modbus Conformance classes 0, 1, and 2. The Modbus/TCP Server supports up to 16
simultaneous connections. These connections are not shared with any other applications. Other TCP-based
application protocols such as SRTP Server use a different set of TCP Connections.

CPU Restrictions and Open Issues
Subject
Description
Battery installation
When installing a new battery, when there currently is no battery installed, the battery must be
installed while the CPU has power. Failing to follow this procedure could result in the CPU not
powering up.
If a battery is installed while power is off (and there was no battery previously installed), and
the CPU fails to power up, simply remove the battery, power cycle the CPU and then install
the battery.
Ethernet Disconnect
During Word for Word
Change
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. If this occurs, you should go offline and then back
online again.
Non-GE Fanuc VME
Modules Operating as
VME Masters
Non-GE Fanuc VME modules operating as VME bus masters have not been tested with the
RX7i. Users interested in integrating this type of functionality should contact technical support.
Store of Hardware
Configuration with
Multiple GBCs
Storing a hardware configuration containing two or more GBCs twice may cause one GBC to
fail configuration. Clearing the hardware configuration between stores will prevent this fault
from being generated.
Simultaneous Clears,
Loads and Stores Not
Supported
Currently, the RX7i does not support multiple programmers changing CPU contents at the
same time. The programming software may generate an error during the operation.
Power Cycle During
Online Edit
If the user stores a folder to flash that is configured to power up from flash and then
subsequently power is cycled in the middle of a Online Edit session, the programmer will still
indicate that the Online Edit session is in progress after the power cycle. The user should
cancel the Online Edit session to continue.
Fault Reporting With
Analog Expanders
For fault reporting when an analog expander is used in a Series 90-70 Expansion Rack, a
special case exists when the ALG230 base module is in slot 2 and an expander module is
present in slot 9. In this case, if any expander module loses communication with the base
module, then the fault reports for all 16 channels for that expander display the slot number as
0. The circuit number will be a value from 9 to 120, as shown in the following table. The I/O
reference address for each channel is displayed as blank.

If the CPU is power cycled during the process of writing to flash, and is configured to power
up from flash, a fault will be generated on power up.

Description
Hardware Configuration
Not Equal After Changing
Target Name
If the user stores a hardware configuration to flash which indicates that “Logic/Config Power
up Source” is set 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
Both PLC and IO fault tables 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.
VME Modules Using
Program Type AM Codes
When Block Transfers are enabled with a VME memory region that uses one of the program
type AM Codes, the Rx7i CPU sometimes generates block transfer (BLT & MBLT) cycles to
access the associated VME memory. Therefore, if you have a VME memory region configured
to use one of the program type AM Codes (AM Codes 3Ah, 3Eh, 0Ah, or 0Eh), be sure to
follow at least one of these two rules:
a) The memory region's Interface Type parameter must not be set to "Qword Access (64-bit)",
and the VME Block Transfer parameter must be set to "Disabled".
-ORb) The system may not contain any "program" and "data" VME memory regions with
overlapping VME addresses. (If more than one VME module were to respond to a BLT or
MBLT cycle, a system error could result.)
Setting Force On/Off by
Storing Initial Value
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.
CMM Comm_req
Restriction
Due to an issue in the CMM firmware, the SNP COMM_REQ Read System Memory (7202)
executed on a CMM module does not execute correctly for lengths greater than 760 words.
Incorrect data is written to the SNP Master. Users should not use lengths greater than 760
words.
Number of Active
Programs Returned as
Zero
The SNP request Return Controller Type and ID currently returns the number of active
programs as zero.
Serial I/O Failure at 115K
During Heavy Interrupt
Load
Rare data corruption errors have been seen on serial communications when running at 115K
under heavy interrupt load on the PLC. Under heavy load applications, users should restrict
serial communications to 57K or lower.
RAND_MAX and rand()
Function Incompatible
In the C Toolkit, the RAND_MAX system variable is defined as a 32-bit integer. However, the
rand() function returns a 16-bit integer. By definition, rand() should return an integer between
0 and RAND_MAX.
Incorrect Commreq Status
For Invalid Program Name
The program name for PACSystems is always "LDPROG1". When another program name is
used in a commreq accessing %L memory, the error that is generated is a 05D5, which is an
invalid block name.
Unable To Communicate
Through Some Third Party
Serial Cards
PACS Systems serial ports do not work with some third party serial cards.
SNP ID Not Always
Provided
Unlike the Series 90, the PACSystems CPU’s SNP ID will not appear in the Machine Edition
programmer Show Status display. Service Request 11 will always return zeros.
Bus Read or Write May
Return Status of 5 Instead
of 4.
In some cases, the Bus Read/Write Status Word returned may be 4 instead of 5 when the
ending address is out of range.
Must Have Logic If
Powering-Up From Flash
If the application will configure the CPU to retrieve the contents of flash memory at power-up,
be sure to include logic along with hardware configuration when saving to flash memory.

Description
PACSystems C Toolkit
Definition For Unpacked
BCD 4 Digit Year Structure
Wrong
The definition of unpacked_bcd_tod_4_rec in release 1.0 and earlier of the PACSystems C
Toolkit is incorrect. The definition should be:
struct unpacked_bcd_tod_4_rec{
T_WORD huns_year;
T_WORD tens_year;
T_WORD month;
T_WORD day_of_month;
T_WORD hours;

};
GBC COMMREQ status
address
Do not specify %I or %Q memory for the status address location for a COMMREQ to the
GBC70. Memory types %R, %AI, and %AQ work properly. In the %I and %Q case, the
COMMREQ completes with a status of 0.
Powering Up
Unconfigured Expansion
Racks During Run Mode
Powering up an expansion rack that is currently not configured will cause the sweep time to
increase significantly (approximately 30-40 ms for each rack) for one sweep. If the PLC is in
run mode, and multiple expansion racks are powered up at the same time, the software
watchdog timer may go off. The user should ensure that all expansion racks are configured
before being powered up, or power up the expansion racks while the PLC is in stop mode, or
increase the software watchdog timeout appropriately, in order to avoid this problem.
CPU may not detect lowbattery condition
PACSystems CPUs may not detect a low-battery condition early enough to provide a
meaningful warning to the user to replace the battery. A battery with very low capacity may
still have a terminal voltage high enough to report that it is a good battery. In this case, when
the battery starts supplying the memory power (battery backup), the battery voltage would
quickly drop to unacceptable levels, with little warning to the user before failure. To insure
against data loss, users should replace batteries in accordance with the guidelines provided in
the CPU Reference Manual, GFK-2222. Additionally, users could save logic and hardware
configuration to flash.
Extended Memory Types
for IO Triggers
%R, %W and %M cannot be used as IO triggers.
GBC in Expansion Rack
May Fail to Power Up
Occasionally, a IC697BEM731 module located in an expansion rack may fail to power up
when power to that rack is cycled off/on. The module’s OK light will flash and then all module
lights will go off. Power cycle the rack again to recover.
Possible Machine Edition
software inability to
connect
Infrequently, an attempt to connect a programmer to a PLC via Ethernet will be unsuccessful.
The normal connection retry dialog will not be displayed. Rebooting the computer that is
running the programmer will resolve the behavior.
Repeated store of folder
containing C blocks
After many stores of a folder that contains C blocks, the PLC CPU and/or Ethernet module
may cease operation. Power-cycle the main PLC rack to recover. The possibility of undesired
th
operation may be avoided completely by power-cycling the main PLC rack after every 5
store of a C block folder.

If an Update Datagram message requests 6 or less bits or bytes of data, the PLC will return a
Completion Ack without Text Buffer. The protocol specifies that the returned data will be in the
Completion Ack message, but it may not be.
“Clear All” operation may
time out
A Clear All to a system with a very large hardware configuration may timeout, with the error:
Error 8097: Server Error - Transfer Error: Host driver timed out. [0x6A][0x01]
The selected memory could not be cleared
Machine Edition software does not disconnect when the error occurs and a retry is usually
successful.
Don’t use multiple targets
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, Machine Edition software reports hardware configuration and
logic "not equal".
Nuisance Faults (GBC in
configuration)
Four “Non-critical CPU software event” faults may appear when some hardware
configurations that contain GBC modules are stored. These faults may be ignored.

Description
Sequence Store Failure
In systems with very large hardware configuration, it is possible to encounter a “PLC
Sequence Store Failure” error when writing the configuration to flash. To work around this
error, either:
1. Perform an explicit clear of flash prior to performing the write.
2. Increase the operation timeout used by Machine Edition software prior to performing
the write.
Service Request 6:
rounding of length
parameter
Processing for Service Request 6 Change/Read Number of Words to Checksum incorrectly
rounds the specified length to the next largest multiple of 8 bytes, rather than 8 words.
Consequently, each sweep may checksum fewer words than expected.
PID algorithm
See “Documentation Errata” on page 23. For the case that bit 2 is set to 1 and bit 0 is set to 1,
the product will operate in a manner opposite to the description. The derivative term is added
when it should be subtracted.
High Speed Counter
Module Fails to Power Up
Correctly
Rarely, after some extreme power loss events, a High Speed Counter with interrupts enabled
may fail to power up successfully. After failure, the HSC may continue to function but will
cease to communicate with the PLC. There are no module fault indicators for this event and
the HSC ready bit will remain ON. The user should power cycle again to restore normal
function.
Thermocouple Module
Fails to Power Up
Correctly
After some power loss events, the Horner Thermocouple module (HE697THM160) may fail to
power up successfully. After failure, the %AI data will not be updated correctly and will
continue to return zero values. There are no module fault indicators for this event. The user
should power cycle again to restore normal function.
Fault Contacts on
Modules in Expansion
Rack
When an expansion rack powers up, the slot fault contacts will prematurely indicate that the
modules in the expansion rack are not faulted before they complete their power up. Use I/O
point fault contacts to verify validity of the I/O.
Fault Contacts on Remote
I/O Station
If multiple faults exist in a Series 90-70 Remote I/O Station and one of them is corrected, a
FAULT contact that uses the Remote I/O Station’s module reference will incorrectly indicate
that no faults exist at the Remote I/O Station.
BIT_SEQ Function Block
DIR Parameter
The BIT_SEQ Function Block should require the user to flow BOOLEAN logic into the DIR
parameter, but currently does not. If no DIR parameter is present, the BIT_SEQ will increment
by default.
Ethernet Restrictions and Open Issues
Subject
Description
Number of SRTP Requests
Tallied May Vary
When running multiple SRTP client channels, the number of requests, as reported by the
client and the server, may differ between the connections.
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. If quicker recovery of the SRTP connection is needed, modify the
“wkal_idle” Advanced User Parameter to reduce the TCP keep alive timer down to the
desired maximum time for holding open the broken connection. Refer to TCP/IP Ethernet
Communications for PACSystems, GFK-2224, for details.
Reporting of Duplicate IP
Address
The RX7i does not log an exception or a fault in the PLC Fault Table when it detects a
duplicate IP address on the network.
REPP Does Not Save
Results of Aborted PING
The station manager REPP command does not retain the results of a PING that is aborted
due to error. The PING results are reported when the PING is aborted, but subsequent REPP
commands give the results of the last successfully terminated PING.
Multiple Log Events
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.
Intermittent SNTP Loss of
Synchronization
Under moderately heavy EGD traffic load, the Ethernet Interface may occasionally lose
synchronization with its SNTP time server and generate exception log event 29, entry 2=bH.

Description
Reduced EGD
Consumption with Large
Numbers of Produced
Exchanges
When large numbers of EGD exchanges are produced at a rapid rate, some consumed EGD
exchanges may exhibit lower rates of consumption than expected. To better balance
produced and consumed EGD exchange performance, reduce the number or frequency of
the produced exchanges configured at this Ethernet Interface.
SRTP Communication
Delays
Average latency of communications on SRTP channels may vary considerably due to TCP
retransmissions. SRTP client applications should be designed to take this variance into
account. In particular, SRTP client applications migrating from Series 90-70 SRTP Servers to
RX7i may need to lengthen SRTP timeout parameters.
PLC Fault Table Last
Update Date and Time
The PLC Fault Table web page does not display the correct data for the PLC date and time
field. The date and time displayed are the PCs local date and time, not the PLCs date and
time.
Spurious ‘Ethernet Failure’
Error
On rare occasions, the error “Module hardware fault” may be reported on the Ethernet
daughterboard. The corresponding fault in the exception log is Event = 1, followed by text
"Ethernet failure". This fault is a nuisance fault and may be ignored.
Web Server Failure Under
Heavy Load
After several hours of heavy load on the web server, the web server may fail to return pages
and may cause a LAN system-software fault to be logged. The web server will resume
serving pages when the load is reduced.
Pushing Ethernet Restart
Button Multiple Times
Pushing the Ethernet Restart button multiple times rapidly without letting the Ethernet module
complete the restart may cause the PLC to go lights out. The user should power cycle the
CPU to recover.
Reference Table Web Page
Restriction
After the user selects a user defined table, if the user then tries to go back to the pre-defined
table of %R1-%R60, an error message may be displayed stating “An error was detected
when trying to retrieve setting from PC cookie”.
Fault Table Web Page
Restriction
On both the I/O and PLC Fault Table web pages, the PLC program name is not currently
displayed in the area provided.
Cannot Set FTP Password
The CHPARM TPASSWORD Station Manager command fails. Processing an AUP File
containing parameter “tpassword” generates an error.
Reference Table Web Page
Format
When using Netscape 4.7 to view the reference table web page, the size of the columns is
incorrect. The first column is much wider than the others.
Spurious Ethernet Fault
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.
Release 2.00 PLC Faults
Are Not Identified on Web
Page
When any PLC Fault Table entries defined for Release 2.00 are displayed using the Ethernet
interface web server, the PLC Fault description contains only a generic message instead of
the proper fault text.
Cannot send EGD
Commands to Self
EGD Commands return COMMREQ Status 8F90H (= invalid IP address) when addressed to
initiating Ethernet Interface’s own IP address. If you wish to send an EGD command to
yourself, please use the loopback IP address (127.0.0.1).
Unexpected EGD
Commreq Status
EGD Commands may return COMMREQ Status 9590H (= internal error) instead of the
expected B190H (= Can’t locate remote node) when unable to locate a remote device on the
network.
Too many EGD Commands
Reported as Internal Error
The Ethernet Interface supports 10 simultaneous EGD commands. When an 11 EGD
Command COMMREQ is issued, the CSW value 9590H (= internal error) is returned.
EGD Command Passwords
Are Not Supported.
Optional passwords are not allowed within EGD Command COMMREQs.
Very Heavy EGD
Production/Consumption
at Server May Cause EGD
Command Timeouts
Very heavy EGD production and/or consumption at a server device may cause EGD
command timeout errors when another device attempts to send EGD commands to that
server. If EGD commands must preempt normal production, you may set the “gcmd_pri”
Advanced User Parameter to 2 (see GFK-2224, Appendix A). Note that by doing so, EGD
exchange production may be delayed.
SRTP Server Errors Can
Cause Timeouts at
Channels Client
The SRTP Server in the PACSystems Ethernet Interface can encounter various errors when
the remote Series 90 PLC client takes down an SRTP connection and then establishes a new
connection. This can cause unexpected channel timeout errors 0190H or 0290H at the client.
The SRTP server errors in the Ethernet exception log are identified as Event = 2; Entry 2 may
be 001cH, or 0021H.

Description
EGD Command Range
Failure Can Write Partial
To PLC Bit Memory
When an EGD Command attempts a write operation to a bit-mode PLC reference memory
range (%I, %Q; %T, %M, %SA, %SB, %SC) where the amount of data be written exceeds
the configured size of that reference memory, the command will return failure status but
partial data may be written into the reference memory. The amount of partial data written
depends upon the starting bit memory location and the data length as follows:
If data starts on a byte boundary (location = (8*n) + 1), no partial data is written.
If data does not start on a byte boundary (location = (8*n)+1) and data exceeds the
configured reference memory by 8 or more bits, partial data is written from the starting
location to the next byte boundary after the starting location.
If data does not start on a byte boundary (location = (8*n)+1) and data exceeds the
configured reference memory by less than 8 bits, partial data is written from the stating
location to the end of configured reference memory.
For a Write PLC Memory command, this can occur when writing data into the target PLC. For
Read PLC Memory or Read Exchange commands, this can occur when writing data received
from the target PLC into the local PLC memory. The logic application must not use any data
returned to the local PLC if the EGD command status indicates failure.
To avoid writing partial data to the local or remote PLC, be sure that bit memory data
transfers do not exceed the configured reference memory sizes at the appropriate PLC.
Usage of New IP/Subnet
Mask Configuration
Because the Ethernet interface operates using a retained set of IP address + subnet mask
information, a change to these values does not take effect until a restart of the module or
power cycle of the rack containing the module. The user should be aware when altering these
configuration values that their effect is not immediate.
Cannot Change EGD Class
2 UDP Port Number
Processing an Advanced User Parameter File containing parameter “gctl_port” does not
actually change the value.
COMMREQ Length Error
The COMMREQ Status Word value 8190H (="COMMREQ is too short") may also be
reported for EGD Command COMMREQs that are too long (contain more words than
expected).
Producer ID of Zero in
Capabilities Response
Producer ID is set to zero in the EGD Capabilities response if the IP address is set up by the
“setIP” utility. Afterwards, any subsequent Hardware Configuration store will have the
producer ID reported correctly.
No CPU fault logged when
Ethernet Interface in fatal
blink code
The CPU does not log any PLC or I/O Faults when the Ethernet Interface has a fatal blink
code. The user’s application should monitor the LAN interface OK status bit to detect loss of
module.
EGD I/O has unexpected
variability under heavy
load
EGD I/O has intermittent unexpected variability under heavy load. For a Produced Exchange,
EGD samples may occasionally be delayed by as much as a production period.
Ethernet Interface time
drift
If time synchronization is not configured for the Ethernet Interface, it loses time at a rate of
approximately 0.3 seconds per hour.
Clear of large hardware
configurations may cause
log event 08/20
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.

Description
User Memory Accounting
Corrected
Some user memory was not correctly accounted for in releases previous to Release 2.56.
Due to this issue being corrected, it is possible that extremely large folders (>9Mb), which
stored with PACSystems Release 1.0, 1.5 and 1.6 may not store with Release 2.56. In
addition, if such a folder is resident in flash during the firmware upgrade to Release 2.56,
the folder will not be read to RAM successfully. Users with large folders should insure that a
current copy of the stored folder is archived using the programmer application software so
that it can be modified and re-stored after the firmware upgrade, if necessary.
Only one BTM is allowed in the main rack. Multiple BTMs in the main rack will result in
undefined operation.
Only One BTM Allowed in
Main Rack
Logic Executed in Row
Major Instead of Column
Major
Logic execution in PACSystems RX7i is performed in row major order (similar to the Series
90-30) instead of column major (similar to the Series 90-70). This means that some
complicated rungs may execute slightly differently on PACSystems RX7i and Series 90-70.
For specific examples, see the programming software on-line help.
Upgrading Firmware with
Modules in Rack
The process of upgrading the CPU firmware with the WinLoader utility may fail when
multiple IO modules are in the main, remote or expansion racks, due to the time it takes to
power cycle the rack system. If the upgrade process fails, move the CPU to a rack without
IO modules and restart the upgrade process.
NaN Handled Differently
Than in 90-70
The PACSystems RX7i CPU may return slightly different values for Not A Number as
compared to Series 90-70 CPUs. In these exception cases (e.g., 0.0/0.0), power flow out of
the function block is identical to Series 90-70 operation and the computed value is still Not
A Number.
PID Algorithm Improved
The PID algorithm used in PACSystems RX7i has been improved and therefore PID will
function slightly differently on PACSystems RX7i than on the Series 90-70. The differences
are:
The elapsed time is computed in 100 µS instead of 10 mS units. This smooths 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 Request 13
Command Block Must
Contain Zero
When the Service Request function block is used to invoke Service Request #13, the first
word of the command block sets the number of last scans to be executed. If the value of
that word is -1 (or 0xFFFF), then the number of last scans is set to the value in the
configuration.
Changing IP Address of
Ethernet Interface While
Connected
Storing a hardware configuration with a new IP address to the RX7i while connected via
Ethernet will succeed, then immediately disconnect because the RX7i is now using a
different IP address than the Programmer. You must enter a new IP address in the Target
Properties in the CME Inspector window before reconnecting.
Stack Allocation for
Folders Converted from
Series 90-70 Must be
Increased
Series 90-70 folders are converted to PACSystems RX7i with the same stack allocation.
PACSystems RX7i uses more stack space than the Series 90-70, so some folders may not
run after conversion. To increase the stack space, right click the _MAIN block and select
Properties. Stack Size is listed at the bottom of the Properties page. The default stack size
in new PACSystems RX7i folders is 64KB. Folders with a large number of nested calls may
need more stack space. As a general rule, the stack for the converted PACSystems RX7i
folder should be set to approximately three times the stack size of the Series 90-70 version
of the folder. A diagnostic fault will be displayed if the folder runs out of stack space.
Duplicate Station Address
for Modbus Will Conflict
with Other Nodes
The default serial protocol for the RX7i is Modbus RTU. The default Station Address is 1. If
the PLC is added to a multi-drop network, care must be taken that the PLC is configured
with a unique Station Address. Nodes with duplicate Station Addresses on the same
network will not work correctly.
FST_EXE No Longer
Represented by %S121
The PACSystems RX7i implementation of #FST_EXE is different from the Series 90-70
implementation. #FST_EXE is no longer stored in %S (%S121) memory. Instead, it is
stored in a local memory that is not accessible to the user. You can reference #FST_EXE
only by using its name (similar to referencing a symbolic variable).
The #FST_EXE system variable can be accessed (read) in the logic of any block. Just as in
the Series 90-70, PSB blocks and C blocks inherit the #FST_EXE value of their calling
block. Again, as in the Series 90-70, #FST_EXE cannot be written.

Format for Fault Locating
References Changed
Compared to the Series 90-70 CPU, syntax for the fault locating references has changed as

#RACK_00r is now #RACK_000r.
#SLOT_rss is now #SLOT_0rss.
#BUS_rssb is now #BUS_0rssb.
#M_rssbmm is now #M_rssbmmm (adds support for 256 modules).
Existence of old style (Series 90-70) fault locating references will cause errors to be
generated during logic validation. The error generated will have the following format: “Error
9618: Invalid reference type for operand [LD Block,’_MAIN’: Rung 7]”
Slot Restrictions for
Analog Expander Module
in RX7i Rack
The following restrictions apply to Analog Expansion Modules in a PACSystems RX7i rack:
The base module must be in a slot no lower than Slot 4.
The expander module must be in a slot no higher than Slot 11.
No expander module may be in a slot lower than the base module.
Because of these restrictions, and because the 90-70 modules occupy two slots in the
PACSystems RX7i rack, a maximum of three expanders are possible. (Base in Slot 4,
Expanders in Slots 6, 8, and 10 or Base in Slot 5, Expanders in Slots 7, 9, and 11.) Please
note that these restrictions do not apply to Analog Expansion Modules in Series 90-70
Expansion Racks.
Genius Bus Controller
Restrictions
The following restrictions apply to GBCs in PACSystems RX7i:
The minimum CPU sweep time will be gated by the time it takes the GBC to refresh its
outputs and collect its inputs + 500 microseconds. To obtain a smaller sweep time, use
the SUSIO function block or place the GBCs in a scan set that has non-default
characteristics.
If a %W reference address is used for COMM_REQ status or return data, it must be in the
range %W00001 - %W65536.
Storing or clearing a hardware configuration containing two GBCs attached to the same
Genius network may cause a Loss of Device fault for one of the GBCs. This is caused by
the GBCs clearing their SBAs asynchronously. The user can safely ignore the Loss of
Device fault.

PCM (to CPU)
Communications Timeout
The PCM has a default backplane communications timeout value of 5 seconds. After the
PCM has sent a request to the CPU, the PCM applies this timeout while waiting on a
response back from the CPU. In most cases, the CPU will respond well within the 5–second
timeout; however, in certain instances the CPU can take longer than 5 seconds to respond.
These cases are limited to LOADs or STOREs of program and/or configuration -especially if
blocks in the program are larger than 8 KBytes. Folders containing EXE blocks (again with
*.EXE files >8 KBytes) are most likely to cause problems. To ensure that the PCMs do not
observe backplane timeouts, a file must be loaded (using termf) to the PCM. The file must
be a binary file named CPU.ENV. The contents of this file are as below (all values are
specified in hexadecimal):
Once the binary file CPU.ENV (below) is created, use termf to load CPU.ENV to the PCM.
Then execute a soft reset of the PCM. After executing the soft reset, the PCM’s backplane
communications timeout should be 10 seconds.
Note: A copy of the above CPU.ENV file can be obtained from
http://www.geindustrial.com/cwc/gefanuc/support/ControllersIO/s9070-d.htm.
CAUTION
The CPU.ENV file will not be used when a hard reset is performed on the PCM. With
the CPU.ENV file resident in the PCM, a soft reset must be performed after every hard
reset of the PCM. Be aware that it is possible to issue a soft reset COMMREQ from
the Ladder Diagram application; therefore, the application can be modified to handle
the required reset of PCMs after a power cycle of the PLC system.

rack). If the rack jumper is not changed the PLC CPU will not recognize the rack at all and
may not properly identify the error.

Description
Expansion Rack Cable
Connection and disconnection of an expansion rack cable while the CPU is running should
not be attempted. This will cause the PLC to go to the STOP/HALT state.
Expansion Rack Power
Expansion racks should be powered up at the same time the main rack is powered up or
they should be powered up after the main rack has completed its power up initialization. Do
not power up an expansion rack while the PLC CPU is running power-up diagnostics.
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 milliseconds greater than the
normal sweep time to avoid any over-sweep conditions when monitoring or performing online changes with the programmer. Window completion faults will occur if the constant
sweep setting is not high enough.
Large Number of
COMM_REQs Sent to
Module in One Sweep
Causes Faults
A large number of COMM_REQs (typically greater than 8) sent to a given board in the
same sweep may cause Module Software faults to be logged in the PLC fault table. The
fault group is 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, COMM_REQs issued to a given board should be
spread across multiple sweeps so that only a limited number (typically 8 or less) of
COMM_REQs 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 COMM_REQ 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.
Loss of VDD100 or
VAL132 After Multiple
Power Cycles
In rare instances, a VDD100 or VAL132 module may not configure after power has cycled
repeatedly in a very brief period of time. A Loss of IO Module fault will be generated.
In extremely rare instances, this may also cause other modules to fail to configure, without
generating additional loss of module faults. These additional failures may cause
communication with the Ethernet Interface to fail.
The user can recover from either of these cases by turning off power for at least 5 seconds
and then restoring power. This will provide sufficient "off-time" to ensure that all modules
can powerup properly.

Configuration of IP Address is
Required Before Using Ethernet
Communications
Description
A label on the rear wall inside the CPU’s
battery compartment identifies the MAC
address assigned to the CPU’s embedded
Ethernet Interface. The label is visible when the
battery is removed from its compartment. (The
battery does not need to be disconnected to
temporarily remove it from the compartment.)

The Ethernet Interface within the CPU module cannot operate on a network until a
valid IP address is configured. The necessary Ethernet addressing information must
be configured prior to actual network operation, or to recover from inadvertent
changes to the Ethernet addressing data at the Ethernet Interface. Use one of the
following methods to initially assign an IP address:
■
Connect a serial terminal to the Station Manager port of the PACSystems
RX7i . Then use the CHSOSW command to enter the desired IP address.
For details, see the PACSystems TCP/IP Communications Station Manager
manual, GFK-2225.
■
Temporarily assign an IP address to the module using the SetIP tool over
the Ethernet network. For details, see TCP/IP Ethernet Communications for
PACSystems, GFK-2224.
■
The Ethernet Interface automatically obtains a temporary IP Address from a
BOOTP server on the network. For details, see TCP/IP Ethernet
Communications for PACSystems, GFK-2224.
Once a temporary IP address has been set up, the Ethernet Interface can be
accessed over the network (such as by the Machine Edition programming software).
The programmer should then be used to configure the proper IP address for the
Ethernet Interface.
Proper IP Addressing is Always
Essential
The PACSystems RX7i CPU’s embedded 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 RX7i
and other nodes on the network. Refer to TCP/IP Ethernet Communications for the
PACSystems RX7i, GFK-2224 for important information on IP addressing. When
storing a new HW configuration to the RX7i, be sure that the HW configuration
contains the proper Ethernet addressing data (IP Address, Subnet Mask, and
Gateway IP Address) for the RX7i.
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 CME Inspector window. Storing a HW Configuration whose
Ethernet addressing data contains an IP Address that is different from the RX7i
target IP address will change the IP address used by the target RX7i 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 CME 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 default (0.0.0.0) or incorrect Ethernet
addressing data to the PACSystems RX7i will result in loss of the Programmer
connection and will require manual corrective action as described above.
Default IP Address (0.0.0.0)
Attempts to Set IP Address via
BOOTP
The default IP address value (0.0.0.0), whether obtained from HW Configuration or
backup configuration, causes the Ethernet Interface to request a temporary IP
address from a BOOTP server device on the network.

Description
LAN Must be Tree, Not Ring
The two Ethernet network ports on the PACSystems RX7i Ethernet Interface must
not be connected, directly or indirectly, to the same network device. 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 RX7i Ethernet modules will continually reset.
Reporting of Duplicate IP Address
The PACSystems RX7i does not log an exception or a fault in the PLC Fault Table
when it detects a duplicate IP address on the network.
Multiple Zero Period EGD
Exchanges May Not Produce
Similar Numbers of Samples
If more than one EGD produced exchange is configured for a production period of
zero, the exchanges may not produce similar numbers of samples. Due to the way
that scheduling occurs when multiple exchanges are scheduled “as fast as
possible,” some zero period exchanges may produce significantly more samples
than others. For more consistent EGD production, configure the produced EGD
exchanges with non-zero production periods.
Changing IP Address While SRTP
Connection Open May Generate
Log Events
Open SRTP Server connections established with a remote SRTP client are not
terminated as expected when the RX7i’s IP address is changed (typically by storing
a new HW Configuration to the RX7i). A Series 90 SRTP client (“SRTP channels”)
reports either a 9690H or 0190H status; the SRTP connection may remain open
until the connection is terminated as a result of a client timeout.
Series 90-70 Datagrams are Not
Supported
Series 90-70 datagrams are not supported. This means that Series 90-70 - format
variable list requests from Host Comm Toolkit applications will fail. (Series 90-30 –
format datagrams are supported, but cannot access %P or %L memory in the RX7i.)
AUP Parameter Should Not be
Changed
The Advanced User Parameter “wsnd_buf” should not be changed by the user.
Changing the value of this parameter may cause the LAN LED to go out and the
Ethernet Interface to drop connection.
Heavy Load Can Block Station
Manager
As explained in TCP/IP Communications for PACSystems Station Manager Manual,
GFK-2225, Chapter 1, a heavy EGD and/or SRTP load can block Station Manager
operation.
One-time delay of EGD Production
(and possibly Consumption) if
more than 24 SRTP Server
Connections are started
simultaneously
If more than 24 SRTP Server connections are established simultaneously, EGD
th
Production may be briefly delayed for each connection after the 24 when the
connections are first made after power is applied. If EGD consume acceleration has
been disabled, then EGD Consumption will also be delayed. The delay only occurs
once when the SRTP Server connection is established for the first time after
Powerup. No delay is experienced for the first 24 SRTP Server connections.
Web Server Browser Restrictions
Internet Explorer version 4.0 running on Windows 98 will give an error when the
reference table web page is accessed. Web Server operation has been verified with
Internet Explorer version 5.0
Very Heavy EGD
Production/Consumption at Server
May Cause EGD Command
Timeouts
Very heavy EGD production and/or consumption at a server device may cause EGD
command timeout errors when another device attempts to send EGD commands to
that server. If EGD commands must preempt normal production, you may set the
“gcmd_pri” Advanced User Parameter to 2 (see GFK-2224, Appendix A). Note that
by doing so, EGD exchange production may be delayed.
AUP Parameter Name Change
Beginning with Release 2.00, the following Advanced User Parameters have been
renamed to match the Ethernet hardware port identification:
“lduplex1” is changed to “lduplex1a” (Ethernet Port 1A duplex state)
“lduplex2” is changed to “lduplex1b” (Ethernet Port 1B duplex state)
“lspeed1” is changed to “lspeed1a”
(Ethernet Port 1A network speed)
“lspeed2” is changed to “lspeed1b”
(Ethernet Port 1B network speed)
The old parameter names are no longer supported; use of an obsolete parameter
name will result in a configuration processing error and an Ethernet exception (Entry
= 2, Entry 2 = 06).
Existing AUP files using the obsolete parameter names will have to be changed to
use the new parameter names.

Description
SRTP Application Timeouts Must
Accommodate Network Connection
Overhead
The application timeouts within SRTP Channels also include the time needed to
establish and maintain the underlying network and SRTP connection. Examples are
establishing the TCP connection for a new channel, establishing communication
with the remote device, and TCP retransmissions during Channel operations. If the
time needed for TCP connection establishment or maintenance exceeds the userspecified channel application timeout values, an application timeout will occur.
Channel application timeouts are temporary errors; the channel continues to run.
Client Channels TCP Resource
Management
The OS Network stack hangs on to the TCP resources associated with a connection
for a period of time after the connection is closed. It applies to the initiator of the
close, which is almost always the client side. This time is referred to as the “TCP
Linger Period”. Once the TCP Linger Period expires (60 seconds in the current OS
implementation), the TCP resources are released. Application developers using
client channels need to be aware of this behavior when designing their logic. A finite
number of TCP resources are allocated to client channels, and if channel
connections are brought up and down so fast that these resources are depleted,
then the application may have to wait until a TCP resource frees up in order to
establish another client channel (a COMMREQ Status of 0xA890 is returned if no
TCP resources are currently available; application should wait and try again).
SRTP Client Channels provides features that help the user preserve TCP
connections. These include a period time where one can establish an SRTP
Channel and specify the channel to run at a given interval, or run as fast a possible.
One can also specify a number of iterations, or allow the channel to run forever.
Additionally, SRTP Channels allows channel re-tasking of an active channel to the
same remote device, where the parameters of an active channel, such as changing
the channel command type (Read/Write), number of repetitions, time periods, local
memory address, remote memory address, etc. can be changed. SRTP Channels
also allows channel re-tasking of an active channel to a different remote device
(changing the remote device’s IP address, etc.). However, re-tasking to a different
remote device will neither conserve TCP connections, nor save on the time it takes
to create a channel.
Idle Modbus/TCP connection
between a Series 90 and a
PACSystems may be prematurely
terminated
An idle Modbus/TCP connection between a Series 90 and a PACSystems may be
prematurely terminated. There is an incompatibility between the TCP "Keep-Alive"
timer values on the PACSystems Ethernet Interfaces and Series 90 Ethernet
Interfaces. The issue is that the default value of the keep-alive timer for the Series
90 modules is set to a much higher value than for the PACSystems.
To keep TCP connections open between a Series 90 Ethernet Interface and a
PACSystems Ethernet Interface, the Series 90 Interface Advanced User Parameter
wkal_time should be set to the value 750 to match that of the PACSystems. With
this change, TCP connections remain open indefinitely. Note that this same issue
occurs for SRTP Client Channels that have infrequent traffic and can be resolved by
using the same technique.
Attempt to open 17 or more
Modbus server connections may
appear successful
If more than the maximum 16 supported Modbus Server Connections are attempted,
the TCP connection may succeed, but no data may be subsequently transferred.

Selection (PIDISA or PIDIND) and Gains”
The description of the Derivation term should be replaced/augmented with this text:
The Derivative term is the time rate of change of the Error term in the interval since the last
PID solution.
Derivative = ∆Error / dt = (Error – previous Error) / dt,
where
dt = Current PLC elapsed time - PLC elapsed time at previous PID solution.
In normal mode (that is, without Reverse-Action mode), this is the change in the error term.
(Error – previous Error) = (SP – PV) – (previous SP – previous PV)
= (previous PV – PV) – (previous SP – SP)
However, when the Reverse-Action mode bit in the Config Word is set, the sign of the
change in the error term is reversed.
(Error – previous Error) = (PV – SP) – (previous PV – previous SP)
= (PV – previous PV) – (SP – previous SP)
The change in the error term depends on changes in both the Set Point and the Process
Variable. If the Set Point is constant, the difference between SP and the previous SP is zero
and has no effect on the output. However, Set Point changes can cause large transient
swings in the derivative term and hence the output. Loop stability may be improved by
eliminating the effect of Set Point changes on the derivative term. Set the third bit (bit 2) of
the Config Word to 1 to calculate the Derivative based only on the change in PV. For bit 2
set in normal mode (bit 0=0).
(Error – previous Error) = (previous PV – PV),
and with bit 2 set in Reverse-Action mode (bit 0 = 1),
(Error – previous Error) = (PV – previous PV).
