③ 摘要
在一个可编程序的控制器系统,中央处理单元(CPU)提供了成功和实时性完成控制系统施行所必需的大脑和中枢系统。它快速并高效率地扫描所有系统输入信号,检查并处理可应用的逻辑部件,并且更新所有的系统输出信号。另外,它本身也也有自检功能来扫瞄以确保,它的构造是原封的。在这整个系统中,包括CPU的各种各样的功能模块,典型的扫瞄技术,I/O 接口和应用存储器、电源和系统诊断。
In a programmable controller system, the central processing unit (CPU) provides both the heart and the brain required for successful and timely control execution. It rapidly and efficiently scans all of the system inputs, examines and solves the application logic, and updates all of the system outputs. In addition ,it also gives itself a checkup each scan to ensure that its structure is still intact. Included will be the various functional blocks in the CPU, typical scan techniques, I/O interface and memory uses, power supplies, and system diagnostics.
