基本单元-32 DI估计运输规模

DSDI452是ABB公司生产的一款多处理器计算机硬件和软件体系。

DSDI452涉及到一个多处理器计算机硬件和软件体系结构，其中两个或多个相同的处理器连接到一个共享的主存储器，对所有输入和输出设备具有完全访问权限，并由一个操作系统实例控制，该实例平等对待所有处理器，不保留任何处理器用于特殊用途。

DSDI452用于20个24V数字输入和12个数字输出的组合单元。

数字输入模块有多种功能，例如可以接收常开或常闭触点信号，可以接收电压或电流信号，可以配置为独立的输入模块或与其它模块组合使用，还具有多种保护功能，例如过压保护、过流保护、短路保护等，以确保安全可靠地运行。

ABB DSDI452项目的最小可加载单元是对象。有可见的项目对象，如资源、任务、程序列表和程序，还有隐藏的对象，如进程图像、功能块、变量和消息。当执行加载>更改的对象时，只加载项目更改的对象。在高级任务或资源上必须注意是否出现副作用。加载对象需要初始化相关的对象。此过程将擦除以前有关该对象的所有信息。DSDI452在其他对象中运行的程序依赖于被加载对象的信息，可能会以在某些情况下可能不可取的方式做出反应。例如，一个变量的导出属性将被更改，然后该变量将被重新加载，其值将被重置为初始值。确保已更改对象的加载不会对被控制的过程产生负面影响。当只发生对象删除时，加载>更改的对象将只删除站点上的对象。

Basic unit -32 DI Estimated transport size

DSDI452 is a multi-processor computer hardware and software system produced by ABB.

DSDI452 refers to a multi-processor computer hardware and software architecture in which two or more identical processors are connected to a shared main memory, have full access to all input and output devices, and are controlled by an operating system instance that treats all processors equally and reserves no processor for a special purpose.

The DSDI452 is used in a combined unit of 20 24V digital inputs and 12 digital outputs.

Digital input module has a variety of functions, such as can receive normally open or normally closed contact signals, can receive voltage or current signals, can be configured as an independent input module or combined with other modules, but also has a variety of protection functions, such as overvoltage protection, overcurrent protection, short circuit protection, etc., to ensure safe and reliable operation.

The smallest loadable unit of an ABB DSDI452 project is an object. There are visible project objects, such as resources, tasks, program lists, and programs, and hidden objects, such as process images, function blocks, variables, and messages. When you do Load > Changed objects, only the objects that the project changed are loaded. Attention must be paid to side effects on high-level tasks or resources. Loading an object requires initializing the associated object. This procedure erases all previous information about the object. DSDI452 programs running in other objects depend on information about the object being loaded and may react in ways that may not be desirable in some cases. For example, the exported properties of a variable will be changed, and then the variable will be reloaded and its value will be reset to its initial value. Ensure that the loading of the changed object does not negatively affect the controlled process. When only object deletion occurs, Loaded > changed objects will only delete objects on the site.
