EMERSON 1C31179G02 遠(yuǎn)程輸入/輸出模塊
1C31179G02圖形式指令結(jié)構(gòu)：程序由圖形方式表達(dá)，指令由不同的圖形符號(hào)組成，易于理解和記憶。系統(tǒng)的軟件已把工業(yè)控制中所需的獨(dú)立運(yùn)算功能編制成象征性圖形，用戶根據(jù)自己的需要把這些圖形進(jìn)行組合，并填入適當(dāng)?shù)膮?shù)。1C31179G02在邏輯運(yùn)算部分，幾乎所有的廠家都采用類似于繼電器控制電路的梯形圖，很容易接受。如西門子公司還采用控制系統(tǒng)流程圖來表示，它沿用二進(jìn)制邏輯元件圖形符號(hào)來表達(dá)控制關(guān)系，很直觀易懂。較復(fù)雜的算術(shù)運(yùn)算、定時(shí)計(jì)數(shù)等，一般也參照梯形圖或邏輯元件圖給予表示，雖然象征性不如邏輯運(yùn)算部分，也受用戶歡迎
明確的變量常數(shù)：圖形符相當(dāng)于操作碼，規(guī)定了運(yùn)算功能，操作數(shù)由用戶填人，如：K400，T120等。PLC中的變量和常數(shù)以及其取值范圍有

Instruction structure in graphical b: the program is expressed in graphical b, and the instructions are composed of different graphical symbols, which is easy to understand and remember. The software developer of the system has compiled the independent operation functions required in industrial control into symbolic graphics. Users combine these graphics according to their own needs and fill in appropriate beters. In the logic operation part, almost all manufacturers adopt ladder diagram similar to relay control circuit, which is easy to accept. For example, Siemens also uses the flow chart of the control system, 1C31179G02which uses the graphical symbols of binary logic elements to express the control relationship, which is very intuitive and easy to understand. More complex arithmetic operations and timing counting are generally represented with reference to ladder diagram or logic element diagram. Although they are not as symbolic as logic operations, they are also popular with users
Explicit variable constant: the graphic symbol is equivalent to the operation code, which specifies the operation function, 1C31179G02 and the operands are filled in by the user, such as k400, T120, etc. The variables and constants in PLC and their value ranges are
