September 26, 2000 GFK-1512H IMPORTANT PRODUCT INFORMATION READ THIS INFORMATION FIRST Product: IC693 CPU Modules IC693CPU350-CE with Firmware Release 10.00 IC693CPU360-CF with Firmware Release 10.50 Introduction This document contains information that is not available in any other publication; therefore, we recommend you save it for future reference. This document discusses IC693CPU360 firmware release 10.50, which corrects the problems listed in the section “Problems Resolved in this Release (10.50).” This document also discusses the features of firmware version 10.00, which is currently the latest firmware available for the IC693CPU350 (this CPU is scheduled to be updated to release 10.50 later). Feature Highlights of Firmware Release 10.50 for CPU360 Only No new features. Feature Highlights of Previous Firmware Release 10.00 Note: The following CPU features will be documented in VersaPro 1.1 (when released) on-line help. • Support was added for the IC693DSM314 servo module. • Add support for storing Local Logic Programs. These programs are stored to the CPU from the programmer (VersaPro 1.1 is required to use this feature). These programs will automatically be stored from the CPU to the appropriate smart option module. The limit on the size of all Local Logic Programs is 65280 bytes. • Reboot after Fatal Fault – If activated, this feature enables the IC693 PLC system to automatically resume normal operation after a fatal fault has occurred. Following the fatal fault, the PLC will automatically reset and resume execution. If fatal faults are present following the power up, the PLC will still be allowed to transition to run mode. The user can enable this feature through a configuration parameter, and can identify the maximum number of retries and the time period these retries may occur within through new Service Request #48. New Service Request 49 may then be used to determine the number of fatal faults and retries that have occurred. This feature requires VersaPro 1.1 to configure. • Addition of the Drum Sequencer function block. This function block operates in the same manner as it does on the IC200 CPU. VersaPro 1.1 is required to use this feature. Feature Highlights of Previous Firmware Release 9.00 The following features were introduced in release 9.00. • Software Floating-Point. The CPU350 and CPU360 support all of the floating-point function blocks that are currently supported by the CPU352. They are implemented in firmware using floating point emulation. These Floating-Point math function blocks are described in the IC693 PLC Reference Manual. • CPU360 user memory increased to 240K bytes. %R, %AI, and %AQ references are configurable up to 16K of %R, 8K of %AI and 8K of %AQ memory using the MS-DOS PLC programming software, version 9.02. These MS-DOS and Windows are registered trademarks of Microsoft Corporation 2 Important Product Information GFK-1512H three references are configurable up to 32K version 2.2 of the Windows PLC programming software and version 1.0 of the VersaPro programming software. Configuration instructions for this feature are described in the MSDOS IC693 Programming Software User’s Manual, and are included in on-line help in both Windows PLC programming software packages. Note that the CPU350 does not support configurable user memory. Its user memory is set at a fixed value of 32K bytes. • Sequential Event Recorder. The Sequential Event Recorder function block can be used to record up to 1024 samples of 32 individual discrete (bit) references. Both of these CPUs support this function block. Instructions on programming the Sequential Event Recorder are found in the IC693 PLC Reference Manual. • Break-free SNP. The SNP protocol no longer requires a break to operate. This allows SNP to work over a wider variety of modems. Hardware Identification The following table shows the revision level of the circuit boards used in the current version of these CPUs.

Important Product Information 3 GFK-1512H • The MS-DOS PLC Programming Software Version 9.02 or later must be used to take advantage of the features introduced in firmware release 9.00. These features are listed in the section “Feature Highlights of Previous Firmware Release 9.00.” Operating Notes Hardware Update to Enhance EMC Performance A hardware update to version CE (from version BE) of these CPUs was made to allow them to provide enhanced EMC performance. The update will also allow faster backplane I/O data transfers to be implemented in the future, while still meeting all EMC requirements. This update is fully compatible with all existing products. To realize the maximum EMC benefit, this version of the CPU must be used with the latest 90-30 baseplates. Radiated emissions (EN 55011) of the 90-30 system are reduced with this update. NOTE: The first letter of the version designator indicates the hardware revision level. For example, in version CE, C indicates the hardware version, and E indicates the firmware version. Therefore, any version whose first letter is C or later will have this EMC performance enhancement. User Information Cleared when Upgrading Firmware User information, consisting of program, configuration, CPU ID (used for SNP communications), and status tables 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, if required, must be set separately using the programming software or the Hand-Held Programmer (HHP). Firmware Upgrade Hardware Requirements Note: The Model 350 and 360 CPU operating firmware is stored in FLASH memory. The firmware upgrade is provided on a floppy disk 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” floppy drive, MS-DOS version 3.3 or later (or Windows 95 or later), a hard drive, and one RS-232 serial port is required. In addition, a serial cable and RS-232/RS-485 converter are required. The following serial cable/converter kit is available from GE Fanuc: IC690ACC901 Mini Converter (RS-232/RS-485) Kit with serial cable Option Module Revision Requirements • Ethernet Interface Module Compatibility. All IC693 Ethernet Interface (IC693CMM321) modules used with these CPUs 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 programming software. During a Run Mode Store (Alt + S hot key combination) of a large program block (greater than 14 kilobytes), the Ethernet module may time out, causing communications to fail. Changing the Communications Window to Run-to-Completion mode, or storing the program in Stop mode, will allow the store to take place successfully. • FBC Compatibility. FBC version 3 or later is required for these CPUs. Writing to Flash Using the Windows PLC Programming Software When writing very large programs to flash memory, it may be necessary to increase the Windows PLC programming software request timeout value to avoid receiving a request timeout message. An upper bound of 25 seconds is typically satisfactory 4 Important Product Information GFK-1512H Storing Large Configurations The IC693 PLC will normally support 20 DSM314 modules in a system. This number may be reduced by other modules in the system, such as APM and GBC modules. It may also be further reduced if using datagrams that read the reference or fault tables. If the configuration and user program are stored at the same time, the presence of either C blocks within the LD program, or a C logic program may also affect the number of DSM314 modules that may be included in a system. If the store fails, it may be possible to work around this problem by first storing the logic program and then storing the configuration on a separate store request. The number of modules supported may be further reduced by the size of CPU user memory. No Model Number Checking with DOS-based programmer The No Model Number Checking feature does not support storing a 311, 313, 321, 323 or 331 configuration to a Release 9.0 or later CPU. Minimum Sweep Time for the CPU 360 Reduced in Release 10.50 The minimum sweep time (while in run mode) for Release 10.50 of the CPU360 has been reduced about 1 ms from that of Release 10.00 Simultaneous Load and Store When operating with multiple programmers attached, if a store operation is initiated by one programmer, while a load operation is already in progress, the load request will 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. Problems Resolved in this Release (10.50) for CPU360 Only Rotate Right and Rotate Left functions do not handle error condition correctly In releases prior to 10.50, the Rotate Right and Rotate Left functions do not correctly handle rotating a string with a rotation request greater than 16 times the length (in words) of the array. These functions should only be used with the rotation request less than 16 times the length (in words) of the array. These function blocks will now treat any request to rotate more than the length of the array as a copy request. Time of Day clock at powerup may not operate In releases prior to 10.50, this would result in a Fatal PLC CPU HW FAULT being logged. The supercap had to be shorted to restore the board to normal operation. Error when run-mode storing, loading, or verifying exactly 50 blocks in run mode. In releases prior to 10.50, if a programmer attempts to verify with a CPU containing exactly 50 subroutines (not including main), the operation will fail. If the programmer attempts to load from a CPU containing exactly 50 subroutines, the operation may fail, or the programmer may appear to succeed, but incorrectly load the data. If an attempt to do a run-mode store on a CPU with exactly 50 subroutines is attempted, the operation will fail. Fatal Fault retry does not work correctly for some faults. In releases prior to 10.50, the fatal fault retry feature will not work correctly for faults which reoccur on powerup (such as system configuration mismatch). The CPU will go into a loop where it consistently powers up, experiences the fault and retries. This will continue indefinitely. Important Product Information 5 GFK-1512H Problems Resolved in Firmware Release 10.00 User Flash Write and Erase Failure User Flash Write/Erase operations were failing when the Flash Memory was subjected to significant temperature variations. This failure is now detected correctly, an error message is displayed to the user, and the user can retry the operation. IC693 PLC can Automatically go to run Mode. The IC693 PLC could automatically go to run mode if a configuration enabling the keyswitch is stored to a PLC with the keyswitch in the ON position whose initial configuration had disabled the keyswitch. Retentive Contact Previous Values Table not Being Cleared The previous values tables for retentive contacts was not being cleared out on a Stop to Run transition Problems Resolved in Firmware Release 9.10 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. This has been corrected in release 9.10 so that these higher references will now work the same as the lower references. 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. Problems Resolved in Firmware Version 9.01 SNP Master mode on CPU Ports With some very large configurations and version 9.00 firmware, after a power-cycle, CPU ports set up for SNP Master would need to have their configuration re-stored for the protocol to accept COMM_REQs. This is corrected in version 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 corrected in version 9.01. 350 and 360 9.00 Upgrade After upgrading to version 9.00 on a 350 or 360 PLC, the user flash area would need to be written to or cleared afterwards with an HHP, DOS, or Windows programmer. Otherwise, the RAM contents would be cleared on a powercycle. This is no longer necessary when upgrading to 9.01 or later. 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. 6 Important Product Information GFK-1512H Restrictions and Open Issues Timing Issue with ALG220/221 Modules May Result in 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 (catalog module revisions F and earlier may show this problem; revision G has fixed this problem). Certain 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. (NOTE: CPUs 341, 331, 321, 313, and 311 have not exhibited this timing problem reading %AI values.) The IC693 PLC will generate a fatal fault if a ladder containing DOIO function block calls to a smart module is repeatedly placed in RUN then STOP mode A problem was found with the CPU where a ladder containing a call to a DOIO function block would cause the PLC to run out of system memory. This is caused when the PLC transitions to run mode and back to stop mode several times. If the configuration is stored, the system memory will be freed, and the PLC will resume normal operation. IC693 PLC CPU may Develop Fatal Fault During Store of Folders with Large Configurations The IC693 PLC CPU may generate a fatal fault during a store of a folder with an especially large configuration. This may be made worse by storing a program and configuration at the same time, or by having datagrams from a programmer present during the store. PID Integral Contribution The PID Integral Contribution is not calculated correctly with an integral rate of 0 or 1. A CPU360 Configuration Stored to CPU352 may Cause Fatal Fault If a CPU360 configuration file is stored to a CPU352, the PLC may generate a fatal fault when transitioning to run mode. Reading from an Invalid Flash Part may Cause a Watch Dog Timeout If a corrupted flash part is read, the Watch Dog Timer on the PLC may be triggered. This can be fixed by completing a valid flash store. Fatal Fault Occurs when Configuring a Module with the HHP Following a Maximum Size PLC Store The IC693 PLC CPU may generate a fatal fault while attempting to configure a module with the Hand-Held Programmer (HHP) following a maximum size store to the PLC. Firmware Update Fail Following Power-up with Clear M/T and a Write to Flash Firmware update may fail following a power-up with Clear M/T pressed on the Hand-Held Programmer and a write to flash. Cycling power on the PLC will enable the upgrade to proceed.
