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通道数据采集器
