NI PXIe-4141通道數(shù)據(jù)采集器中文資料：
NI PXIe-4141通道數(shù)據(jù)采集器Series 90-30 PLC的CPU類型Series 90-30可編程邏輯控制器有多種CPU型號，其速度、I/O容量、用戶內(nèi)存大小和高級功能各不相同。這種模型的多樣性使系統(tǒng)設(shè)計者在選擇最適合所設(shè)計系統(tǒng)的模型時具有相當(dāng)大的靈活性。CPU有兩種基本類型，嵌入式和模塊化。嵌入式類型滿足了良好的低成本PLC的需求，NI PXIe-4141通道數(shù)據(jù)采集器但缺乏模塊化系統(tǒng)的功率、可擴(kuò)展性和通用性。在嵌入式類型中，CPU內(nèi)置在基板中。在模塊化類型中，CPU包含在插件模塊中。嵌入式CPU嵌入式CPU是嵌入式CPU底板的一部分。在這些產(chǎn)品中，CPU和存儲器集成電路芯片被焊接到基板的背板上。本章討論這些產(chǎn)品的CPU功能。NI PXIe-4141通道數(shù)據(jù)采集器
英文資料
CPU Types for Series 90-30 PLCs There are numerous CPU models available for the Series 90-30 PLC which differ in speed, I/O capacity, size of user memory, and advanced features. This variety of models gives a system designer considerable flexibility in choosing the one best suited to the system being designed. There are two basic types of CPUs, Embedded and Modular. The embedded types fulfill the need for a good low cost PLC, but lack the power, expandability, and versatility of the modular systems. In the embedded types, the CPU is built into the baseplate. In the modular types, the CPU is contained inside a plug-in module. Embedded CPUs The embedded CPUs are part of an embedded CPU baseplate. In these products, the CPU and memory integrated circuit chips are soldered to the backplane board of the baseplate. This chapter discusses the CPU features of these products.NI PXIe-4141通道數(shù)據(jù)采集器
