>>>型号:1769-NPKSDN 模块 执行多任务和程序互换
【功能描述】
1769-NPKSDN模块是PLC（可编程逻辑控制器）的一个关键组成部分，展现了PLC基础技术的显著进展。这种进展主要体现在两个核心方面：执行多任务和程序互换。
1769-NPKSDN多任务执行能力允许在一个PLC系统中同时装载多个CPU模块，每个CPU模块都负责执行特定的任务，并控制与其任务相关的I/O模块的存取。按照IEC 61131-3的概念，
这可以被视为通过多配置来执行多任务。这些CPU模块可以有多种用途，包括逻辑控制、顺序控制、运动控制以及过程控制。在Windows操作系统的环境下，这些模块还能执行PC机任务，为用户提供更多的选择。
1769-NPKSDN模块还体现了PLC软件模型从传统模式向更灵活、更混合式的控制系统的转变。传统的PLC软件模型通常只包含一个资源，运行一个任务，并控制一个程序，且这些都在一个封闭系统中运行。然而，
在1769-NPKSDN模块中，一个“资源”内可以定义一个或多个任务，这些任务在被配置后可以控制一组程序或功能块，从而提供了更高的灵活性和扩展性。
总的来说，1769-NPKSDN模块是PLC技术发展的重要里程碑，它以其多任务执行能力和灵活的软件模型，为工业自动化领域的用户提供了更高效、更可靠的解决方案。

【英文介绍】
The 1769-NPKSDN module is a key component of the PLC (Programmable Logic Controller) and demonstrates significant progress in the underlying PLC technology. This progress is mainly
reflected in two core aspects: multitasking and program interchange.
1769-NPKSDN Multitasking capability allows multiple CPU modules to be loaded simultaneously in a PLC system, each of which is responsible for performing a specific task and controlling
access to the I/O modules associated with its task. According to the concept of IEC 61131-3, this can be seen as multi-tasking through multi-configuration. These CPU modules can be used for
a variety of purposes, including logic control, sequence control, motion control and process control. In the Windows operating system environment, these modules can also perform PC tasks,
providing users with more choices.
The 1769-NPKSDN module also embodies the transformation of the PLC software model from the traditional model to a more flexible and hybrid control system. The traditional PLC software
model usually contains only one resource, runs one task, and controls one program, and all of these run in a closed system. However, in the 1769-NPKSDN module, one or more tasks can be
defined within a "resource" that, when configured, can control a set of programs or functional blocks, thus providing greater flexibility and extensibility.
Overall, the 1769-NPKSDN module is an important milestone in the development of PLC technology, which, with its multi-task execution capability and flexible software model, provides users in
the field of industrial automation with more efficient and reliable solutions.
