  1. Plc, robot and cad / cam are called the three major pillars in the modem factory automation. plc, as the head of the three, has become the leading basic automatic equipment in the field of the industry control in the early 1980s " but as a matter of fact, plc being with the lack of friendly man machine interface, rnakes no close relationship between human and machineometimes it even can not be promoted and applied in some fields aiming at the situation mat those imported products are too expensive while domestic products are of rare famous brands, a plc man - machine interface - plc monitor is developedthis paper systemically introduces the developing procedure for the whole system, including how to design hardware and software system. especially emphasizing plc communication protocol. real time message accessing, lcd controller instruction set, definition of data construction for message & tag screens and how to display thern, assignment of internal resource of cpuealization in software among plc & manitor, file format defining a nd download of user data, etcplc monitor will compensate some weakpoints of plc, and extend the application rangeimultanneously enhance the performance of plc and increase the attached value of mechanical machines, undoubtedly it will see hight market prospect

    針對人機界面進口產品的高昂價格和國產品牌稀少的這一現狀，研製開發了一種plc人機界面? plc監控器。本文系統地介紹了整個系統的開發過程，包括硬體系統、軟體系統的設計及實現，重點介紹了plc通信協議，監控器的基本工作原理以及期望實現的功能，監控器電源電路、 sram存儲器掉電保護電路、 cpu監控器電路、按鍵輸入電路的設計及按鍵狀態的讀入，時鐘信息的設定與讀取， cpu液晶顯示器指令系統，信息畫面及標簽數據結構的定義及顯示方法， cpu內部資源的分配，監控器與plc通信的軟體實現，文件格式的定義以及畫面數據的下載等。 plc監控器彌補了plc一些方面的不足，可以擴大plc的應用范圍，提升機械設備的檔次，增加設備的附加價值，具有一定的市場前景。
  2. In computing, ( a ) a complete set of machine code instructions for a computer, or family of computers ; ( b ) a set of types of instruction for a high level language

    在計算技術中， （ 1 ）計算機或計算機系列的一套完整的機器代碼指令集， （ 2 ）一套高級語言的各類指令集。
  3. Abstract : some main problems of the superhigh speed nc machine tools, such as superhigh speed spindle vector controller, servo system of quick - response, reduced instruction set and other auxiliary functions in superhigh speed cutting are introduced in the paper

    文摘:介紹了超高速數控機床控制系統的幾個主要方面：超高速主軸矢量控制器、快速響應的伺服系統、精簡指令集計算機系統及超高速切削中的其他輔助功能。
  4. The filter in bpf was implemented by a pseudo machine, which consists of an accumulator, an index register, a scratch memory store, and an implicit program counter. bpf can be directly programmed via ioctl system call and the pseudo machine instruction set, it can also be programmed by using libpcap function library, which can access many kinds of packet capture facilities provided by oses ( bpf is the important one in them )

    Bpf的過濾器是由假想的過濾器虛擬機實現的，對bpf的編程，可以通過ioctl系統調用和過濾器虛擬機的指令集來直接編程，也可以通過libpcap提供的庫函數來編程，它能訪問許多種操作系統內核提供的包過濾設施（ bpf是其中重要的一種） 。
