CPU固件CPU固件包含的基本操作说明。固件由GE产品工程团队开发。它存储在EPROM或闪存中，具体取决于特定的CPU。CPU固件升级更新新固件的更新时间。新固件版本y包含对新功能的支持或对现有功能的改进。一旦增加了新版本的CPU固件，所有新CPU都将随该版本一起销售。GE Web si的支持部分列出了CPU版本号和相关功能。有关GE Web si的信息，请参阅apr。可以从新固件中受益的用户可以选择通过安装新固件来升级其CPU。根据要升级的CPU类型，在两个堡垒中升级e。本页中的CPU固件和PROM配置选项卡显示每个CPU的固件存储设备类型。这两种类型是：EPROM对于在EPROM中存储固件的CPU，升级是通过更换CPU的EPROM ipss来完成的。升级套件包含新的EPROM ips upda标签和安装说明。升级嵌入式CPU系统中的EPROM，必须拔掉插槽中的插头，才能访问上的PROM插槽。如果是小型CPU，则必须拔下并拆卸CPU。闪存对于固件在闪存中存储的CPU，升级是通过将新固件复制到CPU的闪存中完成的。可以从GE购买升级套件。升级套件包含必要的更新标签和说明。此方法不需要拆卸。fi下载可以通过Q apr CPU上的电源端口进行，也可以通过CPU前面的端口（如果有）进行。applicab方法将记录在升级工具包说明中。下载固件升级文件也可在GE Web si的支持区域找到。有关Web si信息，请参阅apr。订购一个升级套件，从dermine侧面的识别标签上写下您当前固件版本的完整目录号，然后致电您的发行版。如果您不确定当前的固件版本，请参阅下一页的标题“删除CPU修订版本”。闪存固件升级程序通过将PC机连接到应用程序串行端口并运行固件软盘附带的PC Loader软件，操作系统固件可升级。用于此任务的pur应该是一台IBM AT patib或更高的PC，其RAM至少为1。或高密度。软盘驱动器MSDOS版本。或一个硬盘驱动器和一个RS串行端口。此外，还需要一个微型转换器串行驾驶室。以下微型转换器串行驾驶室套件可用：ICACC微型转换器套件RSRS，带驾驶室和引脚适配器。本产品记录在附录D中。删除CPU修订版本如果您计划更改系统，您需要知道您的CPU是否支持这些更改。您的CPU的特性和功能由其修订版硬件和固件决定。本节讨论可以使用dermine CPU的修订级别以及相关特性和功能的方法。直接方法从CPU附带的重要产品信息IPI表中获取信息。但是，如果您的CPU固件已升级，IPI将不会指示当前版本级别。确定CPU固件版本级别的最可靠方法是使用程序员从CPU读取固件版本。您的编程器必须连接并处于在线或监控模式，并且必须通电。例如，在Logicsr STATUS and CONTROL（逻辑状态和控制）屏幕上有一个改进的软件版本。该字段中显示的数据如。是固件版本级别。有关更多详细信息，请参阅Logicsr编程软件或您使用的编程软件。间接方法检查侧面标识标签上的目录号。
CPU Firmware The CPU firmware contains the basic operating instructions for the . Firmware is developed by a GE product engineering group. It is sred in either EPROM or Flash memory depending on the particular CPU. CPU Firmware Upgrade Upda From time time new firmware is reased. A new firmware version y contain support for new features or improvements existing features. Once a new version of CPU firmware is reased all new CPU s will be sold with that version. The Support section of the GE Web si lists CPU revision hisries ting version numbers associad features. See apr for infortion on the GE Web si. Users who could benefit from a new firmware rease y oose upgrade their CPU by installing new firmware. Upgrades e in two forts depending on the type of CPU be upgraded. The CPU Firmware and PROM Configuration tab in this apr shows whi type of firmware srage device ea CPU has. The two types are: EPROM For CPUs with firmware sred in EPROM the upgrade is done by replacing the CPU’s EPROM ipss. The upgrade kit contains new EPROM ips upda labels and installation instructions. upgrade the EPROM in an embedded CPU sysm the in slot must be unplugged gain access the PROM socket on the . In the case of a lar CPU the CPU must be unplugged and disassembd. Flash For CPUs with firmware sred in Flash the upgrade is done by copying a new firmware fi the CPU’s Flash memory. An upgrade kit y be purased from GE. The upgrade kit contains the necessary fis upda labels and instructions. This method does not require disassembling the . The fi downloading is done either through the port on Q apr CPUs the power supply or through a port on the front of the CPU if it has one. The applicab method will be documend in your upgrade kit instructions. Downloadab firmware upgrade fis are also found in the Support area of the GE Web si. See apr for Web si infortion. order an upgrade kit wri down the full catalog number of your from the identification label on the side of the dermine your current firmware revision vel then call your distribur. If you are not sure what firmware version you currently have see the heading on the next page Dermining CPU Revision vels Versions. Flash Firmware Upgrade Procedure The operating sysm firmware is updad by connecting a PC patib pur the applicab serial port and running the PC Loader software included with the firmware floppy disk. The pur used for this task should be an IBM AT patib or betr PC with a minimum K of RAM one . or high density . floppy drive MSDOS version . or lar a hard drive and an RS serial port. In addition a miniconverrserial cab is required. The following miniconverrserial cab kit is ailab: ICACC Miniconverr Kit RSRS with cab and pin pin adapr. This product is documend in Appendix D. Dermining CPU Revision vels Versions If you plan ke anges your sysm you will need know if your CPU can support those anges. The features and capabilities of your CPU are dermined by its revision vels hardware and firmware. This section discusses methods that you can use dermine your CPU’s revision vels and associad features and capabilities. Direct Methods Obtain the infortion from the Important Product Infortion IPI sheet that came with your CPU. However if your CPU firmware has been upgraded the IPI will not indica the current revision vel. The surest way dermine a CPU’s firmware revision vel is read it from the CPU by using your programmer. Your programmer must be connecd the and be in Online or Monir mode and the must be powered up. For examp on the Logicsr STATUS and CONTROL screen is an im cald SOFTWARE REVISION. The data displayed in that field su as . is the firmware revision vel. See the Logicsr Programming Software or the for the programming software you use for additiol details. Indirect Method eck the catalog number prind on the identification label on the side of the .
