GFK-2123G February 27, 2004 IMPORTANT PRODUCT INFORMATION READ THIS INFORMATION FIRST Product: IC693CPU374 CPU Module with Ethernet Interface IC693CPU374-BG (and later) with CPU Firmware Release 11.10 This document contains information that is not available in any other publication; therefore, we recommend you save it for future reference. This release of the Series 90™-30 PLC CPU374 is a maintenance release that addresses several issues in CPU and Ethernet TCP/IP firmware. See page 3 for details. Hardware Identification The following table shows the revision level of the circuit boards used in this version of the IC693CPU374. CPU Model (Version) Circuit Board ID CY3A1 (CPU) IC693CPU374-BG and later E35A1 (Ethernet) Firmware Identification Revision CPU Catalog Number CPU Firmware Ethernet Daughterboard Firmware IC693CPU374-BG and later Main: 11.10 (45A1) Boot: 11.00 (10A2) Main: 1.02 (03A1) Boot: 1.00 (15A2) Note: The new firmware is compatible with all previous firmware and hardware versions of the IC693CPU374. Firmware Upgrade To upgrade a CPU374 to the latest firmware version (11.10), you must purchase the field upgrade kit 44A751579-G05 or download it at no charge from the web (http://www.gefanuc.com/support/plc/rs9030.htm). Firmware upgrades require the IC690ACC901 Miniconverter and Cable Kit. Documentation GFK- 0356, Installation and Hardware Manual GFK-0467, PLC CPU Instruction Set Reference Manual GFK-1541, TCP/IP Ethernet Communications for the Series 90 PLC User’s Manual, GFK-1186, TCP/IP Ethernet Communications Station Manager Manual 2 Important Product Information GFK-2123G CPU Functional Compatibility HHP Compatibility The CPU374 does not support the Hand Held Programmer. Programmer Version Requirements CIMPLICITY® Machine Edition Logic Developer version 2.60 or later, VersaPro version 2.03 or later, or CIMPLICITY Control version 2.50 or later must be used to configure and program the CPU 374. C Toolkit Compatibility Version 4.00 or later of the C toolkit must be used for C programming. IC693CMM321 Ethernet Option Module Version Requirements All Series 90-30 Ethernet Interface (IC693CMM321) modules used with this CPU should be updated to IC693CMM321 firmware release 1.10 or later. FBC Compatibility FIP Bus Controller version 3 or later is required for this CPU. Power Supply Compatibility and Requirements The CPU374 is compatible with any of the Series 90-30 power supplies, except Revisions A through J, Revision W, and Revision X of Power Supply IC693PWR321. If the IC693PWR321 is used, it must be Revision K through V, or Revision Y or later. ■ If a Release 11.01 or later CPU374 is used with Revision X or W of the IC693PWR321, it will always power up in a cleared state – Program, Configuration, Stored Values, Override Tables, and Fault Tables are all cleared. ■ If a Release 11.00 CPU374 is used with Revision X or W of the IC693PWR321, it may fail to power up properly, or may power up with a Corrupted user memory and/or a Program block checksum failure fault. A High Capacity Power Supply (IC693PWR330, IC693PWR331 or IC693PWR332) is strongly recommended. Power consumption of the CPU374 and its supporting devices are listed below: ■ CPU374 requires 1.48A @ +5VDC (= 7.4 Watts). ■ If used, the converter in the IC690ACC901 serial cable assembly requires 100mA at 5VDC (=0.5 Watts). ■ If used, the IC690ACC900 RS-422/RS-485 to RS-232 converter requires 170 mA at 5 VDC (=0.85 Watts). IC693ALG220/221 Analog Input Module Version Requirements Series 90-30 CPUs 35x/36x/37x are not compatible with versions F and earlier of the IC693ALG220/221 Analog Input Modules. Version G or later of the IC693ALG220/221 must be used with these CPUs. If a version F or earlier IC693ALG220/221 module is used with a 35x/36x/37x CPU, the %AI values reported by the module may exhibit erratic behavior. IC693PBM200 PROFIBUS Master Module Version Requirements All IC693PBM200 modules used with a CPU 374 MUST be updated to firmware version 1.16 or later. When earlier IC693PBM200 versions are used with CPU374, backplane communications errors and PLC faults occur frequently while the CPU is in RUN mode. IC693PBS201 PROFIBUS Slave Module Version Requirements All IC693PBS201 modules used with a CPU 374 MUST be updated to firmware version 1.28.1 or later. Earlier IC693PBS201 versions have issues similar to IC693PBM200 versions earlier than 1.16. Important Product Information 3 GFK-2123G Ethernet Functional Compatibility The following features on the CPU364 are not supported in the CPU374: ■ SRTP Channels (COMMREQs for Ethernet messages.) ■ Name Resolution ■ BOOTP ■ AAUI Port CPU Problems Resolved by this Upgrade Configurable Reference Tables Filled with Random Values after Size Change In previous firmware versions, the configurable reference memory tables (%AI, %AQ, and %R) could be filled with random data values after storing a hardware configuration that changed any of their sizes to a nondefault value. This issue was partially corrected in version 11.04 and is completely corrected in version 11.10. Displayed Value of Free Memory Is Incorrect In previous firmware versions, downloading a very large combination of logic and hardware configuration could cause a connected programmer to display an incorrect Free Memory value (Target | Online Commands | Show Status or PLC | Status). This issue has been corrected in version 11.10. CPU Error if Larger Reference Memory Configuration Stored after Maximum Size Program In previous firmware versions, a CPU 374 allowed users to download a hardware configuration in which the total size of the reference memory allocation plus the previously stored logic was slightly larger than the CPU installed memory. After the configuration download, the CPU stopped communicating and the OK LED would blink at a 50% duty cycle with a 1 second period. In version 11.10, the CPU prevents users from downloading hardware configurations when insufficient memory is available. Ethernet Problems Resolved by this Upgrade EGD exchanges duplicated when powering on from flash. In previous firmware versions, each Ethernet Global Data exchange defined in the Hardware Configuration was started twice when the CPU was powered on if the CPU was configured for Logic/Configuration From PROM and the configuration was stored to flash. The station manager stat g command showed two different exchange indices with the same Exchange ID. This issue has been corrected in version 11.10. Ethernet interface may display fatal blink codes. In previous firmware versions, the Ethernet interface could occasionally experience a fatal fault during heavy network traffic and/or use of the station manager trace command. The interface would become inoperative, and the Ethernet LEDs would display blink code 3-1 or 3-3. This issue has been corrected in version 11.10. Ethernet communications may fail after using Setip utility to assign IP address. In previous firmware versions, when the Setip utility was used to change the IP address of a CPU 374, the backup subnet mask and gateway addresses were retained and could prevent Ethernet communications. See Appendix D of the TCP/IP Ethernet Communications Station Manager Manual, GFK-1186, for information on using Setip. In version 11.10, a valid subnet mask is created from the specified IP address, and the gateway address is reset to This assures that a programmer on the same subnet as the CPU (that is, with no router/gateway between them) can always connect to the IP address installed by Setip. 4 Important Product Information GFK-2123G Open CPU Problems Serial Line Noise During SNP-X Communications May Stop CPU When operating with SNP-X on the power supply serial port, noise on the serial line may cause the CPU to transition to Stop Faulted mode with an Illegal Boolean opcode fault in the PLC fault table. When this fault occurs, the CPU rack should be powered off and on to force an immediate integrity check of the application logic. If a Program block checksum failure PLC fault occurs on power up, the program must be downloaded to the CPU to restore correct operation. To prevent this issue from occurring in a noisy environment, ensure that the serial cable is properly shielded and grounded. To minimize the impact of this issue if it should occur, configure the CPU for Logic/Configuration From PROM and store the application to CPU flash memory. CPU Cleared / Hardware Fault Received when Using EZ Program Store Device to Update RAM and Flash The user program, configuration, stored values, overrides, and fault tables are cleared and a CPU Hardware Fault is logged when the Memory Protect/Run Stop key switch is set to the ON/RUN position and the EZ Program Store Device is used to program the CPU if the EZ Program Store hardware configuration option is set to RAM & FLASH. CPU does not Revert to Backup Ethernet Configuration After Interrupted Store from EZ Program Store Device The CPU retains its current Ethernet configuration instead of reverting to the backup configuration when a push-button store from the EZ Program Store Device is interrupted. (The interruption can take multiple forms, however one example is disconnecting the EZ Program Store Device during the store.) Watchdog Timeout / CPU RAM Memory Cleared when Using C Blocks The user program, configuration, stored values, overrides, and fault tables are cleared and a PLC watchdog timer timed out fault is logged if a C Block compiled for hardware floating point (compiled using the mk3plc7.bat function) attempts a floating point divide by zero. (This problem does not occur if the C Block was compiled for software floating point using the mk3plc.bat function.) Power Supply Serial Port does not Respond to SNP/SNPX Requests The Power Supply Serial Port does not respond to SNP or SNPX requests including the break character if an attach message is received that is missing the last character before the BCC, or a message is received that has an invalid BCC or is corrupted so the calculated BCC doesn’t match the BCC specified in the message. Power to the CPU must be cycled to regain communications. EZ Program Loader not able to Update OEM Protection Locked Machines A CPU 374 cannot be updated with the EZ Program Loader if the CPU has its OEM protection locked even if the EZ Program Loader has the OEM password programmed into it. Important Product Information 5 GFK-2123G Open Ethernet Problems Number of SRTP Requests Tallied May Vary When running multiple SRTP channels, the number of requests, as reported by the client and the server, may differ between the connections. Reporting of Duplicate IP Address The CPU374 does not log an exception or a fault in the PLC when it detects a duplicate IP address on the network (unlike the CPU364). The duplicate IP address is reported in the STAT F output only. TCP Connections May Remain Half-Open on CPU374 Server if Client is Lost If an SRTP client with open connections to a CPU374 server is power cycled or reset, the server’s TCP connection may remain open for a long time (until the TCP keep-alive timer expires) once the client is restarted and attempts to reopen the communication. If quick recovery of the connection is needed, the AUP for TCP keep alive should be used to adjust the keep alive timer down to the desired maximum time for holding open the broken connection. Large Number of IP Re-assembly Failures on Large PING Between CPU374s When sending PINGs large enough to require more than one IP packet (1466 bytes or larger), a larger number than expected of IP ReasmFai tallies will be seen on the client and a corresponding number of no timely response errors will be seen in the PING results. Large SRTP transfers do not exhibit the same behavior. EGD messages always fit in a single packet and thus are not subject to this kind of problem. 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. STAT C Command Reports Invalid Rack/Slot Location The station manager STAT C command reports the CPU374 as being located in Rack 0 Slot 15 instead of Rack 0 Slot 1. 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. 6 Important Product Information GFK-2123G CPU Operational Notes Battery Backup Limitations The expected life of a standard Series 90-30 3-volt lithium battery used to back up a CPU 374 is 1.2 months when used continuously. If a longer battery backup period is required, the external battery module (IC693ACC302) is available. The external battery module provides a battery backup period of 15 months for the CPU374. For additional information, see the External Battery Pack datasheet, GFK-2124. Overrides Not Stored to Flash or EZ Program Store Device When storing reference data to flash or the EZ Program Store Device, overrides are not stored. This means that after the reference data is read back from flash or the EZ Program Store Device and subsequently the PLC is put into Run Mode, the logic may execute differently. Therefore, overrides should not be used if reference data is stored to flash or to the EZ Program Store Device. If overrides are used, particular care should be taken to prevent loading reference data from flash at power up. If this precaution is not observed, unexpected operation may occur upon power cycle. Writing Flash Using a Serial Programmer When writing very large programs to flash memory, you may need to increase the request timeout value in the programming software to avoid receiving a request 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 in Ethernet Operational Notes on page 7. Storing Large Configurations A Series 90-30 PLC using a CPU 374 supports a maximum of 32 DSM314 modules. This number is reduced when other intelligent modules are used in the PLC, such as APM and GBC modules. It may also be reduced when: ■ The number of racks in the PLC increases; ■ The total size of logic, motion and AUP files increases; ■ The application uses C logic blocks or a C logic program; and ■ Connected programmers or HMI devices are used to read reference memory or fault tables. In some cases it may be possible to increase the number of DSM314 modules that the CPU 374 will accept in the hardware configuration by storing logic first and then storing the configuration separately. Simultaneous Load and Store When operating with multiple programmers attached, initiating a store operation from one programmer during a load operation from another programmer will cause the load to fail. Transition Tables are not Cleared when the Reference Tables are Cleared The transition tables are not cleared upon clearing the reference tables through the programmer. Upgrading Firmware with Many Modules in Rack The process of upgrading the PLC firmware with the WinLoader utility may fail when multiple IO modules are in the main, remote or expansion racks, due to the extra time it takes to restart the PLC CPU. If the upgrade process fails, wait until the OK LED on the power supply stops blinking and then click the Retry button on the Winloader Firmware Update Failed dialog box. If the upgrade fails again, move the PLC CPU to a rack without IO modules and restart the upgrade process. PID Integral Contribution The PID Integral Contribution is not calculated correctly with an integral rate of zero or one. Important Product Information 7 GFK-2123G Ethernet Operational Notes Configuration of IP Address 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. Use one of the following methods: ■ Perform the initial configuration using a PLC Programmer connected through the PLC power supply serial port. ■ Connect a serial terminal to the station manager port of the CPU374. Then use the CHSOSW command to enter a temporary IP address. The Ethernet Interface can then be accessed over the network (such as by an Ethernet PLC Programmer). For details, see the TCP/IP Ethernet Communications Station Manager Manual, GFK-1186. ■ Temporarily assign an IP address to the module using the Ethernet network. For details, see the TCP/IP Ethernet Communications Station Manager Manual, GFK-1186, Appendix D. Proper IP Addressing is Always Essential The CPU374’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 CPU374 and for other nodes on the network. Refer to the TCP/IP Ethernet Communications for the Series 90 PLC User’s Manual, GFK1541 for important information on IP addressing. CPU374 May Unexpectedly Consume EGD Exchanges Produced To a Group Address The CPU374 consumes EGD exchanges based solely on their producer ID and exchange ID. Unlike other GE Fanuc products, the CPU374 does not filter consumed exchanges based on the IP multicast group address. Group numbers must not be used as the means of distinguishing EGD consumers when using the CPU374. 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 changed configuration values. When the Ethernet interface restarts, an Ethernet PLC Programmer briefly reports a loss of communications. 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 CPU374 is turned off to indicate posting of faults to the PLC fault tables. In some cases, a 10-second delay may occur before loss of communications is detected. Normal operation resumes once the Ethernet Interface restarts. The STAT LED can be reset using the Station Manager OK command. When the PLC configuration is stored from an Ethernet PLC Programmer, the communications loss occurs immediately after successful completion of the store. Attempts to store configuration plus logic and/or reference tables in one operation can fail. However, storing configuration separately from logic or reference tables always succeeds. 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 or to the EZ Program Store device, Ethernet data communications may be lost. Normal data transfers are temporarily suspended during a Flash or EZ Program Store device store operation. In these cases, Ethernet data transfers (such as used by an Ethernet PLC Programmer connection) will fail when the store exceeds the 16-second maximum period allowed for completion. Upon completion of the store operation, normal operation will resume. If a timeout occurs during a store to Flash or EZ Program Store 8 Important Product Information GFK-2123G device, the timeout value should be increased in the programming software being used. See the User’s Manual for the programming software for more details. Ethernet Flash Test Failure The Ethernet daughter board continually tests the integrity of its flash memory. In the extremely unlikely event that corrupted flash is detected, a Module software corrupted; requesting reload fault is posted to the PLC Fault table, and the daughter board enters firmware loader mode. However, attempting to reload the firmware always fails when a hard failure of a flash memory device has occurred. Invalid Ethernet Restart Event After power is applied, the restart event (event 1H) in the Ethernet Station Manager exception log may occasionally contain 000cH in entry 3, erroneously indicating that a time-out of the Ethernet watchdog timer occurred. This condition does not produce a PLC fault or turn off the Ethernet STAT LED, and it has no effect on subsequent operation. It is unlikely to occur when a power supply recommended in Power Supply Compatibility and Requirements on page 2 of this document is used. Note that an actual watchdog time-out produces a Reset of daughter board fault in the PLC Fault table. YATS32 SNTP Server Configuration Users of the YATS32 SNTP server should either configure the server for broadcast mode or multicast mode, but not for both. If the server is configured for both modes, two time messages will be sent to the PLC either simultaneously, or within a short period of time. First PING Response Lost after Restart of Ethernet Interface Immediately after restarting the Ethernet Interface, the first response to a PING large enough to require more than one IP packet (1466 bytes or larger) is not generated. 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. EGD Performance Information Users requiring detailed EGD performance information should contact their Application Engineer and ask about the EGD Performance Application Note for the CPU374. Multicast Data Not Filtered The CPU374 does not do hardware filtering of multicast data over Ethernet. This means that extraneous multicast messages on the network add an additional load on the CPU374 PLC, and may significantly degrade performance. Sufficient load can cause the CPU374 to reset its communication processor. Changing IP Address While SRTP Connection Open May Generate Log Events SRTP connections established to the client are not terminated gracefully when the CPU374's IP address is changed. SRTP channels report either a 9690H or 0190H status, and possibly remain open until the connections are terminated as a result of client timeouts. Heavy Load Can Block Station Manager A heavy EGD or SRTP load can block Station Manager operation.
