>>>型號:1769-NPKSDN 模塊 執(zhí)行多任務(wù)和程序互換
【功能描述】
1769-NPKSDN模塊是PLC（可編程邏輯控制器）的一個關(guān)鍵組成部分，展現(xiàn)了PLC基礎(chǔ)技術(shù)的顯著進展。這種進展主要體現(xiàn)在兩個核心方面：執(zhí)行多任務(wù)和程序互換。
1769-NPKSDN多任務(wù)執(zhí)行能力允許在一個PLC系統(tǒng)中同時裝載多個CPU模塊，每個CPU模塊都負責(zé)執(zhí)行特定的任務(wù)，并控制與其任務(wù)相關(guān)的I/O模塊的存取。按照IEC 61131-3的概念，
這可以被視為通過多配置來執(zhí)行多任務(wù)。這些CPU模塊可以有多種用途，包括邏輯控制、順序控制、運動控制以及過程控制。在Windows操作系統(tǒng)的環(huán)境下，這些模塊還能執(zhí)行PC機任務(wù)，為用戶提供更多的選擇。
1769-NPKSDN模塊還體現(xiàn)了PLC軟件模型從傳統(tǒng)模式向更靈活、更混合式的控制系統(tǒng)的轉(zhuǎn)變。傳統(tǒng)的PLC軟件模型通常只包含一個資源，運行一個任務(wù)，并控制一個程序，且這些都在一個封閉系統(tǒng)中運行。然而，
在1769-NPKSDN模塊中，一個“資源”內(nèi)可以定義一個或多個任務(wù)，這些任務(wù)在被配置后可以控制一組程序或功能塊，從而提供了更高的靈活性和擴展性。
總的來說，1769-NPKSDN模塊是PLC技術(shù)發(fā)展的重要里程碑，它以其多任務(wù)執(zhí)行能力和靈活的軟件模型，為工業(yè)自動化領(lǐng)域的用戶提供了更高效、更可靠的解決方案。

【英文介紹】
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.
