57C411 处理器模块  允许多处理器操作

型号：57C411

特性

•扩展单处理器数据存储

•允许多处理器操作

•提供高级系统看门狗

•电池备份RAM与电池状态字可用

为任务

LED状态指示灯

•OK—普通内存条功能正常

•BAT OK -电池没有问题

57C411当与单个处理器模块一起使用时，Common内存模块提供了额外的64K或128K字用于存储配置任务和系统的内存常见的变量。当大于。时，需要安装公共内存模块同一个AutoMax机架中使用一个处理器模块并允许处理器相互通信通过Multibus P1总线。即使处理器执行完全不相关的任务，也不需要相互沟通，共同记忆模块仍然需要提供总线仲裁信号这样处理器就可以共享总线。通用内存模块用于存储符号表和其他数据结构需要允许任务在处理器模块之间共享。当一个普通人使用内存条时，系统配置任务和a软件运行所需的部分内存系统的数据存储在这个模块上，而不是存储在处理器模块。公共内存上的系统看门狗定时器

模块都比系统保护级别高一级各个处理器模块上的本地监管机构。当

57C411处理器模块停止正常工作，所有I/O机架内模块复位，所有输出清除。机架中的任何其他处理器模块都将检测到处理器通过一个来自Common的信号关闭内存模块和也将关闭。

•BAT OK - Battery is fine

57C411 When used with a single processor module, the Common memory module provides an additional 64K or 128K words for storing configuration tasks and common variables in the system's memory. When greater than. When using a processor module in the same AutoMax rack, you need to install a common memory module and allow the processors to communicate with each other through the Multibus P1 bus. Even if the processors perform completely unrelated tasks and do not need to communicate with each other, the common memory module still needs to provide a bus mediation signal so that the processors can share the bus. Universal memory modules are used to store symbol tables and other data structures needed to allow tasks to be shared between processor modules. When an average person uses memory, part of the memory needed for system configuration tasks and a software to run the system's data is stored on this module rather than in the processor module.

The 57C411 processor module stops working properly, all modules in the I/O rack are reset, and all outputs are cleared. Any other processor module in the rack will detect that the processor shuts down the memory module via a signal from Common and will also shut down.
