Operating Notes
User Flash Contents
User informa ti on, con si sting of program, configurat i on, CPU ID (u sed for SNP comm uni ca ti on s), and stat u s ta bles in
RAM memory, will automatically be cleared if the CPU firmware in flash memory is changed. You will need to restore
these if upgrading firmware. A recommended procedure is to first back up your user information from RAM memory
to Flash memory. Then write your new firmware to Flash memory (firmware is stored in a different location in Flash
memory than that used for storing user information such as program, configuration, etc.). Finally, write your user
information back out of Flash into RAM memory. As an alternative, your user information (program, configuration,
etc.) can be restored from a computer-based backup program folder using your PLC programming software. The SNP
ID must be set separately, using the programming software or the Hand-Held Programmer (HHP).

Firmware Upgrade Procedure
The Model 364 CPU operating firmware is stored in flash memory. The firmware upgrade is provided on a diskette and
must be serially downloaded from a Personal Computer. An IBM AT personal computer or better PC with a minimum
640K of RAM, one 3.5” diskette drive, MS-DOS version 3.3 or later (or Windows 95 or later), and one RS-232 serial
port is required. In addition, two serial cables are required. The following serial cable kit is available:
•
IC690ACC901, Mini Converter Kit with cable (RS-232/RS-485)
This cable can be assembled from the following parts:
IC690ACC900, RS-232 to RS-485/422 Converter Unit
IC693CBL303, 15 Pin RS-485 Serial Cable
IC690CBL705, 25 Pin RS-232 Serial Cable or IC690CBL702, 9 Pin RS-232 Serial Cable (Only one
of th ese cables is r eq uired. Selection depends on PC Serial Port C onnector.)
•
An additional diskette and an additional cable, IC693CBL316, is required to serially download the Ethernet
firmware from the PC to the CPU.
Option Module Revision Requirements
•
All IC693 Ethernet Interface (IC693CMM321) modules used with this CPU should be updated to IC693CMM321
firmware release 1.10 or later. This is also a requirement of the TCP/IP Ethernet version of the MS-DOS
pr ogram mi ng software.
•
FBC version 3 or later is required for this CPU.
Writing Flash Using a Serial Programmer
When wri ting very large progra ms to flash memory, it ma y be necessar y to increas e th e Windows pr ogr amming
software request timeout value to avoid r eceiving a req u es t timeout message. An upper bound of 25 seconds is typically
satisfactory. For further details, see the item “Store of Program or Reference Tables to Flash may Cause Loss of
Ethernet Communications” later in this section.
Power Supply Requirements
The CPU364 requires one of the three following PLC power supplies: IC693PWR321 (Rev. K or later),
IC693PWR322, IC693PWR330, or IC693PWR331. Power consumption of the CPU364 and its supporting devices are
listed below:
•
CPU364 requires 1.1A @ +5VDC (= 5.5 Watts) .
•
If used, the external AAUI transceiver will require a maximum of 400 mA, or 2.0 Watts (limited by the AAUI
standard). Consult the transceiver documentation to obtain its exact power requirements. The IC649AEA103
transceiver requires 380 mA at 5 VDC (=1.9 Watts).
•
If used, the converter in the IC690ACC901 serial cable assembly requires 100 mA at 5 VDC (=0.5 Watts).
•
If used, the IC690ACC900 RS-422/RS-485 to RS-232 converter requires 170 mA at 5 VDC (=0.85 Watts).
Unreliable AAUI 10Base2 Ethernet T ran scei ver (IC649AEA1 01A)
The external AAUI 10Base2 Ethernet transceiver, available as catalog number IC649AEA101A, has been discovered to
operate unreliably under some conditions. This part is no longer offered. Instead, please use catalog number
IC649AEA103.
Configuration via Serial Port is Required Before Using Ethernet Communications
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. Two methods are
available:
1. Perform the initial configuration using a PLC Programmer connected through the PLC power supply serial
port.
4 Important Product Information
GFK-1490C
2. Connect a serial terminal to the station manager port (port 1) of the CPU364. Then use the CHSOSW
comman d to enter a temporary IP ad dress. The Ethernet Int erface can then be accessed over the network (s u ch
as by an Ethernet PLC Programmer). See TCP/IP Ethernet Communications for the IC69* Station Manager
Manual for details.
Proper IP Addressing is Always Essential
The CPU364’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. Refer to TCP/IP Eth ernet
Communications for the IC69* User’s Manual for important information on IP addressing.
AAUI Cable Attach ment
Power to the PLC must be turned off whenever the transceiver (AAUI) ca ble is conn ected or dis connected at the
CPU364 or at the transceiver. Sudden changes in power supply loading caused by connecting or disconnecting the
transceiver with power on may result in unexpected operation of the CPU364 or other modules.
Connecting th e tr ansceiver with power on may also blow the protect ive Ethernet interface fuse. A blo wn fuse can be
repla ced in the fi el d. Refer to TCP/IP Ethernet Communications for the IC69* User’s Manual for instructions.
SQE Enable
The Ethernet Interface within the CPU364 requires that the SQE test signal be enabled on the transceiver connecting it
to the Ethernet LA N. If you are using an external tr ansceiver , make sure your trans cei ver has SQE enabled.
COMMREQ Operation
The CPU364 receives E thernet Communications Requ est (COMMREQ) funct ion blocks at a uni que Rack /Slot and Ta s k
address. Each COMMREQ sent to the CPU364 must be addressed to SYSID = 0001 (= Rack 00 / Slot 01, the location
of the CPU364) and to TASK = 21 decimal (Note: TASK = 0 is used in COMMREQs sent to the IC693CMM321
Ethernet module). Please refer to the TCP/IP Ethernet Communications for the IC69* User’s Manual for furth er
COMMREQ function block deta ils.
Serial Load/Store of Register Table Causes Loss of Comm unications to Ethernet Programmers
A load or s tore of the PLC Register (% R) ta ble from a PLC P rogrammer connected th rough the CPU serial p ort (using
the connector on the PLC Power Supply) can cause Ethernet applications that use the PLC programmer communications
window to lose communications. This condition occurs when the load/store operation requires more than 10 seconds to
complete (called a “timeout”). For example, transferring a large %R table to the CPU (even at 19,200 baud) may cause
a timeout. If this occurs, the Ethernet Interface will post two or more PLC faults with the text “LAN system-software
fault; resuming”, and fault-specific data starting with 080008 and/or 080042. In addition, faults with text “Bad remote
application request; discarded request” (1B0021) and “Local request to send rejected; discarded request” (110005) may
occur. When these faults occur, the STAT LED on the CPU364 will be turned off to indicate posting of faults to the
PLC fault tables. Normal operation will resume once the transfer completes. The STAT LED can be reset using the
Station Manager OK command.
Ethernet Programmer May Briefly Lose Communications When Configuration Stored
Storing a PLC configuration containing Ethernet configuration values may require the Ethernet Interface to restart itself
in order to use any chan ged config ur ation values. When th e Ethernet In terface r estarts, an Ethernet PLC Programm er
will briefly report a loss of communications. PLC faults similar to those listed under “Serial Load/Store of Register
Table Causes Loss of Communications to Ethernet Programmers” above will occur; and the STAT LED on the CPU364
will be turned off to indicate posting of faults to the PLC fault tables. In some cases, a ten second delay may occur
before loss of communications is detected. Normal operation will resume once the Ethernet Interface restarts. The
STAT LED can be reset using the Station Manager OK comman d.
Important Product Information 5
GFK-1490C
When the PLC configuration is stored from an Ethernet PLC Programmer, the communications loss occurs immediately
after s u cces sful comp l etion of the store. Attempts to st ore configur ation plus logic and/or r eference t ables in on e
operation can fail. However, storing configuration separately from logic or reference tables will always succeed.
Store of Program or Reference Tables to Flash May Cause Loss of Ethernet Communications
While storing the PLC program, configuration, and/or reference tables from PLC RAM memory into Flash memory,
Ethernet data communicat ions may be lost . Normal da ta transfer s are temporarily suspended during the Fla sh store
operation. Ethernet data transfers (such as used by an Ethernet PLC Programmer connection) during a Flash store
operation will fail when the Flash store exceeds the 10-second maximum period allowed for completion. Upon
completion of the store to Flash operation, normal operation will resume.
RUN Mode Pro g ram Store
A stor e of a fol d er conta in ing large (greater th an 14kb) program blocks fr om a P LC Programm er con nected through th e
Ethernet port on the CPU364, or through an IC693CMM321 Ethernet module, may fail and result in momentary loss of
communications. This condition has been observed only when attempting to store a large program to a PLC which is in
RUN mode, and which is configured to use a limited communications window. These conditions cause the store
operation to take the maximum possible period to complete. The failure may occur if this period exceeds 10 secon d s for
an individual program block. If this problem does occur, one of the following options may be used to complete the
store operati on s u cces sfully:
1. Change the PLC configuration to use Run-to-Completion mode instead of a Limited Communications Window for
the st ore operati on.
2. Change the PLC from RUN to STOP mode to complete the store.
3. Str uctur e the folder being st ored to el iminat e larg e progra m blocks or subr outin e block s. This will min imiz e the
chance that any single block will take longer than the maximum 10-second period allowed for storage of that block.
Store of Large Program Blocks from Older Ethernet Programmers
If an attempt is made to store a folder which contains large (greater than 14kb) program blocks or subroutine blocks
using the IC693 MS-DOS programming software, Ethernet Version 6.6 or earlier, the store attempt may fail with the
message “(S83) Program size too large for PLC or invalid user program” displayed. If this problem is observed, the
following options may be used to complete the store operation successfully:
1. Update the IC693 MS- DOS pr ogra mm ing softwar e, Eth ern et Ver sion , to a mor e r ecen t ver sion tha t can be r un in a
DOS box under the Microsoft Windows NT/95 operating system. IC693 MS-DOS programming software,
Ethernet Version 9.02 or later is recommended. (Note: In order to configure the CPU364, Version 9.02 or later is
req uired. ) This opt ion req uire s Micros oft Win dows NT or Micr osoft Win dows 95 to be in stall ed on th e PC that
executes the pr ogramming software.
2. If the ladder contains large (greater than 14kb) program blocks or subroutine blocks, then restructure the ladder to
use sm alle r blocks , eith er by sim plif ying th e progra m or by ma king u se of mor e su broutin e block s th at ar e each
smaller than 14kb in size.
3. If neither of the previous options is practical, the following work-around for the problem may be successful.
Modify the CONFIG.SYS fil e on the MS-DOS programmer PC to decrease the maximum TCP segment si ze used
by the Beame & Whiteside driver. This may be accomplished by changing the values used on the line containing
the following:
DEVICE=C:\BWTCP\TC PI P. SYS 1 460 2920 20
Change the value 1460 to 1024, and change the value 2920 to 2048.
Managing Channels and TCP Connections
In certain conditions, the supply of TCP connections can be totally exhausted. When you issue a COMMREQ to
establish a read or write channel, a TCP connection is created, the transfer(s) are made, then upon completion of all the
6 Important Product Information
GFK-1490C
transfers, the TCP connection is terminated. If an application is constructed so that it rapidly and repeatedly establishes
a channel with only one repetition (one transfer), the available TCP connections for the Ethernet Interface may be
totally exhausted.
Specifically, if your ladder program for issu ing COMMREQs is constructed so it does the followin g , all available TCP
connections can quickly be used up: The number of repetitions (Word 9) in an Establish Read or Write Channel
COMMREQ is set to 1, and a new COMMREQ is issued repeatedly and immedia t el y upon completi on of the prior one.
It is recommended you use “Channel Re-tasking” to avoid exhausting TCP connections. Re-tasking is described in the
TCP/IP Ethernet Communications for the IC69* User’s Manual.

Problems Resolved in Firmware Version 9.10 (Ethernet Version 1.10)
AI & AQ Above Default Values
Release 9.00 provided support for configuring %AI and %AQ above their default values. These new references would
previously only work as extra program memory, and could not be used as actual inputs or outputs on physical modules
in the configuration. Thi s has been corrected in rel ease 9.10 so th a t these high er referen ces n ow w ork the sam e as the
lowe r ref ere nce s.
Load File of Size 1528 Bytes
Loads of a user program where the file was of this specific size would fail. This has been corrected in release 9.10.
C Program with Code Area Greater Than 64K Bytes
Before release 9.10, C Program blocks with code areas greater than 64k bytes would not store. In release 9.10 and later,
‘C’ program blocks code sizes are limited only by available memory.
Ethernet Status Bits
If the Ethernet portion of the 364 module had a watchdog or flash checksum failure, its status bits would be held in the
previous state. In release 9.10 the status bits are cleared in this case.
Handling of heavy network loading conditions
Handling of three types of network errors under temporary heavy network load conditions has been improved.
Error Condition Recorded as MAC Tally Exception Log Event
Lost Carrier LostCarr event c, entry 2 = 102H
Maxim u m Ret r ies Exceeded Frtry event c, entry 2 = 10aH
Late Collision LateColl event c, entry 2 = 10bH
For all these errors, the LLC wi ll tolerat e u p to four consecu tive occurrences of an error before restarting th e LLC.
During an LLC restart, the Ethernet Interface cannot communicate on the network, so fewer LLC restarts result in less
disruption to communications.
Also, the Maximum Ret r ies Exceeded condition is now logg ed in the Eth ernet Interface’s excep t ion log an d the PLC’s
fault table only after a fourth consecutive occurrence, th u s r ed ucing nuisance faul t r eports.
SRTP channel management
An SRTP Channel will now be properly retasked while in the AWAIT_DRSP or AWAIT_CRSP states.
Large PING
PINGing the Ethernet Interface with more than 32739 data bytes no longer causes the Interface to restart.
Time of day clock
The time of day clock maintained by the Ethernet Interface no longer runs about 15 seconds fast per day
%S32 & %S20 in Periodic Subroutine
These status bits could be changed if used in a periodic subroutine. This has been corrected in release 9.10.
Update Mode
When the Ethernet (daughterboard) firmware is in update mode, no fault is logged on the PLC to indicate this. The
firmware update mode is indicated by the flashing of the EOK, LAN, and STAT LEDs. The LEDs flash in unison.

Problems Resolved in Firmware Version 9.01
SNP Master mode on CPU Ports
With some very large configur at i on s and versi on 9.00 firm ware, after a power -cycle, CPU ports set up for SNP Master
would need to have their configurat ion re-stored for the pr otocol to accept COMM_ RE Qs. This is corrected in versi on
9.01.
Online Changes to Reference Tables
Making online changes with the programmer to reference tables could result in a watchdog timeout. This has been
corr ected in version 9.01.
Read from Flash
In version 9.00, reading a folder from flash memory could result in the PLC going into a faulted state. This is corrected
in version 9.01.
CPU364 Restri ctions and Open Problems
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.
DDP2 Name Not Used
In systems u s ing mor e th an 75 Ethernet Global Data exchanges, th e Eth er net Interface may n ot in itialize with the u s erconfigured DDP name (i f any), but rather use the default DDP name. Attempts by remote st a ti on s to communicate with
the Interface using the user-configured name will fail. Possible workarounds include:
1. Reconfigure the application to use less than 75 exchanges, or
2. Have remote stations refer to the Interface by its default DDP name
Same IP Address
Use of the same IP Address by the CPU364 and by another device on the same network results in the PLC Fault Table
message “Bad remote application request; discarded request”. This condition should be identified more precisely.
Trace LZ
While a local Stat ion Manager “TRACE LZ” tr ou bl eshooting comman d i s in effect at an Ethernet In terface, d o n ot is su e
Station Manager “REM <node> TEST” commands to it from a remote Interface. Doing so can cause errant behavior,
including module lockup and loss-of-module in the PLC fault table.
EGD status code
The status code of an EGD exchange is not updated to “16” while performing Name Resolution as described in the
manual. The first status code update occurs when the Name Resolution is complete, either “0” if successful or “4 ” if
unsuccessful.
Write Channel Retasking Error
When retasking a Write Channel, the Ethernet Interface may very intermittently generate exception log event 1c, entry
2 = 5. The channel stops with status code 9590 (= internal error). The application program may issue another Write
Channel COMMREQ to start thi s channel.
Important Product Information 9
GFK-1490C
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.
Timing Issue With ALG220/221 Modules May Result i n Incorrect %AI Values Read by CPU
A problem was found with the IC693ALG220/221 where the actual %AI values reported by the card may exhibit erratic
behavior (ca t alog m odule revisions F and earli er may show this pr oblem; revi s ion G has fix e d this problem). Ce rtain
current or voltage levels within the input range applied to the card could cause the %AI values to report incorrectly.
The problem stems from the use of particular optocouplers, which may exhibit timing issues with these CPU35x/36x
modules.
CPUs 341, 331, 321, 313, and 311 have not exhibited this timing problem reading %AI values.
