April 4, 1995 GFK-1177 IMPORTANT PRODUCT INFORMATION READ THIS INFORMATION FIRST Product: Programming and Configuration Software Package, Version 5.02 IC641SWP736A – 3.5-inch 2DD (Standard Serial COM Port Version) IC641SWP733A – Demonstration Package (Standard Serial COM Port Version) CE641SWP731B – Sequential Function Chart (SFC) Programmer Read this document before installing or attempting to use the IC641 programming and configuration software with your programmable controller system. For more information, refer to the Programming Software User’s Manual, the Programmable Controller Reference Manual, the Sequential Function Chart Programming Language User’s Manual, or the README.TXT file on the master diskette. Release 5.02 of the programming and configuration software provides logic programming and configuration for programmable logic control systems. Release 5.02 is compatible with Release 5.0 and earlier CPUs. If a Bus Controller (IC66*) is used with this release of IC641 software, the Bus Controller must be Release 3.0 or later. In addition, Release 5.02 corrects problems that existed in Release 5.00 or earlier software. These problems are listed in section 5, “Problems Resolved by Release 5.02.” Operational Notes 1. System Requirements: A. The IC641 programming and configuration software requires either a minimum of 590K (604,160) bytes of available MS-DOS application memory, or 545K (558,080) bytes of MS-DOS application memory plus an additional 49K of High Memory Area (HMA), Upper Memory Blocks (UMB), or Expanded Memory (EMS) for the communications driver. For more information, refer to the Programming Software User’s Manual. A minimum 1024K of Lotus/Intel/Microsoft Expanded Memory (LIM EMS 3.2 or higher) is required for optimum performance. If additional MS-DOS application memory is required, system software error ID: 0000 EX: 0000 will occur. Check the AUTOEXEC.BAT and CONFIG.SYS files to remove any device drivers and Terminate and Stay Resident (TSR) programs in order to make more application memory available. For example, the IC641 software does not require the ANSI.SYS driver. B. The IC641 software will occupy approximately 4 Mbytes of disk space. Please make sure you have adequate space on your disk before attempting to install the software. C. MS-DOS 5.0 or higher. D. An 80386 or higher computer with a serial COM port serviced by the National Semiconductor 16550 UART chip is recommended. 2 Important Product Information GFK-1177 2. Installation: For detailed instructions on installing the IC641 software, refer to the Programming Software User’s Manual. The software is licensed to run on a single computer. You may encounter problems during the installation if you try to install the package on multiple computers. The INSTALL disks are copy-protected. Since backup copies of these disks cannot be made, they should be used to install the software and then put in a safe place. If you have over 537 MB of free hard disk space and you have the statement DEVICE= C:\DOS\EMM386.EXENOEM S in your CONFIG.SYS, you will receive the following error, (00032) An unknown error occurred during install initialization. To prevent this error. from occurring, you must specify Expanded Memory in your CONFIG.SYS, e.g., DEVICE= C:\DOS\EMM386.EXE 1024 RAM. If you are using a commercial memory manager, such as QEMMt or 386MAXt, this precaution may not be necessary, and if you have less than 537 MB of free hard disk space, this precaution is unnecessary; however, you may still want to specify Extended Memory as discussed in the “IC641 Software Performance” section below. 3. Demo Version (IC641SWP733): The demo version of the IC641 software will install into the LM90DEMO directory on the hard disk specified during the INSTALL procedure. For example, if you specify that the demo version of software be installed on the C: drive, it will be installed in the C:\LM90DEMO directory. To run the demo software, enter the following at the MS-DOS prompt: C:>CD LM90DEMO C:>LM90DEMO The demo version is fully functional. However, the program size is limited to 750 bytes for _MAIN and 750 bytes per program block. 4. IC641 Software Performance: The IC641 software requires a CONFIG.SYS file with BUFFERS set to at least 15 (BUFFERS=15). To increase performance, the buffers should be increased. If you have MS-DOS 5.0 (or higher) and load DOS High, you should be able to set buffers up to 48. This will help the performance of program searches, program loads, program stores, and other disk operations. The variable tables that were once in memory have been moved to disk. While up to 5000 nicknames are now allowed in the _MAIN variable declaration table, the performance of the software may be affected. For best performance, Lotus/Intel/Microsoft Expanded Memory (EMM) Version 3.2 or higher of at least 1024K bytes and SMARTDRV should be provided. A memory manager is provided with MS-DOS 5.0 (or higher) for a 386 or higher computer. However, some computers or PC configurations will require a memory manager such as 386MAXt, produced by Qualitas, or QEMM-386t or QRAMt, produced by Quarterdeck, to provide the maximum amount of memory for the IC641 software as well as other applications. The following configuration will assist you in setting up your computer system to run the software optimally: IC641 Software (Standard MS-DOS Version 5.0) Configuration CONFIG.SYS DEVICE=C:\DOS\HIMEM.SYS DOS=HIGH ,UMB DEVICE=C:\DOS\EMM386.EXE 1024 RAM FILES=20 BUFFERS=48 t 386MAX is a trademark of Qualitas, Inc. t QEMM-386 and QRAM are trademarks of Quarterdeck Office Systems. Important Product Information 3 GFK-1177 5. Using MS-DOS to Copy Folder Files: WARNING Do not use MS-DOS to copy individual files from one program folder to another or to delete files. Doing so may result in corrupted folders. MS-DOS may only be safely used to copy an entire program folder to another program folder of the same name. 6. Serial Printing: The serial ports, COM1 and COM2, can be used for serial printers. Beginning with Release 5, the serial printer port must be configured with the MS-DOS mode command to match the printer settings. For more information, refer to the Programming Software User’s Manual. 7. Interaction of the IC641 Software with Closed Programming Window: If you intend to change the PLC sweep modes or timers (e.g., Constant Sweep Time, Program Window Times, etc.) while the program window is closed, use Service Request #1 – #4. The PLC Sweep Control and Monitor screen in the IC641 software cannot be used. CAUTION To change PLC modes (e.g., STOP, RUN, etc.) while the programming window is closed, use the CPU switch rather than the IC641 software. 8. Running the IC641 Software from a Disk That Does Not Contain the IC641 Software: If you need to run the IC641 software from a disk that does not contain the IC641 software, set up the $PLCROOT environment variable in your AUTOEXEC.BAT file to point to the location of the IC641 software: SET $PLCROOT=(drive ID):\LM90 4 Important Product Information GFK-1177 9. IC641 Software under Windows 3.x: The IC641 software can run under Windows 3.x. With Windows 3.1, the IC641 software may be run in WINDOWED or FULL SCREEN mode. To run the IC641 Software under Windows successfully, observe the following guidelines: A. At least 49K in Expanded Memory (EMS), an Upper Memory Block (UMB), or the High Memory Area (HMA) must be available for the serial communications driver. If EMS memory is used for the IC641 software, you must ensure that no other device driver or TSR is also using EMS memory. B. The IC641 software should be run using a PIF file. A default PIF file is provided in the program directory. Example screens of the default settings are shown below: Important Product Information 5 GFK-1177 C. Do not attempt to run more than one session of IC641 software at the same time. Doing so may result in corrupted program folders. D. You may, however, bring up the programming and configuration software at the same time as long as one of them is offline, or they both use different COM ports. Be careful not to change the CPU model configured from the configurator while you are in the program editor or reference tables in the programming software. To access the same folder from both the programming and configuration software packages, be sure that SHARE.EXE is not used in the AUTOEXEC.BAT file, or you will receive the message “File System Error.” E. For some display adapters and drivers, you may find that the IC641 software is not displayed in color in WINDOWED mode. However, the software will be displayed in color in FULL SCREEN mode. You may switch between WINDOWED and FULL SCREEN mode by pressing ALT-Enter. Problems Resolved by Release 5.02 1. Greater than 127 Program Blocks and ID: 01255 EX: 00000: If more than 127 program blocks are created and a CALL exists to one above 127, an error log ID: 1255 EX: 0000 would occur when attempting to view the rung with the CALL instruction. This problem has been corrected. 2. ID: 3235 EX: 0015 Error Log During Printing: While printing a program, the error log ID: 3235 EX: 0015 could occur. This problem has been corrected. 3.
