NI PXI-4060數(shù)字萬用表卡要訂購升級套件，請從模塊側(cè)面的模塊標(biāo)識標(biāo)簽上寫下模塊的完整目錄號，確定當(dāng)前固件版本級別，然后致電PLC分銷商。如果您不確定當(dāng)前的固件版本，請參閱下一頁的標(biāo)題“確定CPU修訂級別（版本）”。閃存固件升級程序通過將PC兼容計(jì)算機(jī)連接到適用的PLC串行端口并運(yùn)行固件軟盤附帶的PC加載器軟件來更新操作系統(tǒng)固件。用于此任務(wù)的計(jì)算機(jī)應(yīng)為IBM AT兼容或更好的PC，至少具有640K RAM、NI PXI-4060一個(gè)3.5英寸或高密度5.25英寸軟盤驅(qū)動(dòng)器、MS-DOS版本3.3或更高版本、硬盤驅(qū)動(dòng)器和RS-232串行端口。此外，還需要一個(gè)微型轉(zhuǎn)換器/串行電纜。以下微型轉(zhuǎn)換器/串行電纜套件可用：IC690ACC901，微型轉(zhuǎn)換器套件（RS-232/RS-485），帶電纜和9針至25針適配器。（此產(chǎn)品記錄在附錄D中。）確定CPU修訂級別（版本）如果您計(jì)劃對系統(tǒng)進(jìn)行更改，您需要知道您的CPU是否支持這些更改。CPU的功能和功能由其版本級別（硬件和固件）決定。本節(jié)討論可用于確定CPU的修訂級別以及相關(guān)特性和功能的方法。NI PXI-4060
英文資料
To order an upgrade kit, write down the full catalog number of your module from the module identification label on the side of the module, determine your current firmware revision level, then call your PLC distributor. If you are not sure what firmware version you currently have, see the heading on the next page “Determining CPU Revision Levels (Versions).” Flash Firmware Upgrade Procedure The operating system firmware is updated by connecting a PC compatible computer to the applicable PLC serial port and running the PC Loader software included with the firmware floppy disk. The computer used for this task should be an IBM AT compatible or better PC with a minimum 640K of RAM, one 3.5” or high density 5.25” floppy drive, MS-DOS version 3.3 or later, a hard drive, and an RS-232 serial port. In addition, a miniconverter/serial cable is required. The following miniconverter/serial cable kit is available:IC690ACC901, Miniconverter Kit (RS-232/RS-485) with cable and 9-pin to 25-pin adapter. (This product is documented in Appendix D.) Determining CPU Revision Levels (Versions) If you plan to make changes to your system, you will need to know if your CPU can support those changes. The features and capabilities of your CPU are determined by its revision levels (hardware and firmware). This section discusses methods that you can use to determine your CPU’s revision levels and associated features and capabilities.NI PXI-4060
