PLC，本质上是监控附加装置的外部传感活动，他们接受数据，这些数据提供广泛的活动，如机器性能、能量输出和加工障碍。它们也控制相连的马达启动器、导航灯、阀门和许多其他装置。所有的功能都对应一个惯例，实用程序。
工厂的装配线机械用一个 PLC 就能操纵和监控，过去需要数百的计时器和继电器才能完成这项工作。这台机器或系统用户，如果有的话，很少直接与 PLC 的程序交互。当有必要编辑或创建PLC程序时仅需将个人计算机（但不总是）连到 PLC 上。
8. The processes of sequencing control and interlock logic needed for automobile manufacturing was a time consuming and arduous task, which required manual updating of relays, timers and dedicated closed-loop controllers. When a new year’s model was coming off the drawing board, skilled electricians were called on to reset the production line.(What is a PLC?) （P61）
将数控系统装入一个非常标准的机床，它在控制手柄上有位置感应和马达。这基本上是一个机械师。你能使用一个旋转切削刀具切掉不是你设计的所有金属。具有计算内插的三维金属蚀刻成型可以使得圆被加工得更光滑。
6. They (CNC machine) are complicated machines, full of servomechanisms, and measuring technology that can measure to 0.005mm (0.0001”) while covered in oil. A CNC machine has a minimum of 6 motors (including some to change tools, and one or more to pump oil and coolant various places). This translates to running costs that may be well over $1/minute. (The computer is not a significant part of the cost any more.) (CNC Machining) （P10）
检测传感器部分包括各类传感器、信号检测电路，它的功能是检测机电系统自身工作的工程，在外部环境下的相关参数的改变，将其信息传给电子控制单元。电子控制单元通过检查信息，送出相应的指令到执行机构。
4. Electronic control unit, also known as ECU, is the core of mechatronic systems, responsible for the external commands and the signals output by sensors. It centralizes stores, computes and analyzes the information. Based on the results of information processing,instruction are issued according to a certain extent andpace to control the destination for the entire system. (Mechatronics System) （P7）
相关的基本原理是使用压缩气体，通过气缸内的活塞将闸块压在车轮起作用。之间传输；工程师控制其在同一时间释放到所有独立的闸块单元。
2. Machinery ontology including mechanical rack, mechanical connections and mechanical transmission, which is the basis of mechanical-electrical integration, plays a role in supporting the other functional units of the system and transmitting motion and power. Compared to purely mechanical products, the performance and functionality of integration technology in electrical and mechanical systems have been improved a lot, which requires mechanical ontology to adapt its new status in mechanical structure, materials, processing technology, as well as the areas of geometry. Accordingly, the new ontology is with high efficient, multi-functional, reliable and energy-saving, small, light-weightedand aesthetically pleasing characteristics. (Mechatronics System) （P7）
汽车制造所需的时序控制、互锁逻辑的处理是一项耗时、费劲的工作，它需要手工更新继电器、计时器和特定的闭环控制器。当一个新年度模型脱离制图板，熟练的电工被要求从装生产线。
9. PLCs, in essence, monitor external sensory activity from additional devices.They take in the data which reports on a wide variety of activity, such as machine performance, energy output, and process impediment. They also control attached motor starters, pilot lights, values and many other devices. Both functions respond to a custom, user-created program.(What is a PLC?) （P62）
3. Detecting sensor detecting sensor part includes a variety of sensors and signal detection circuit, and its function is to detect the process of mechatronic systems in the work itself and the changes of relevant parameters in external environment and transmit the information to the electronic control unit. Electronic control unit check the information and sends the corresponding control issues to the actuator. (Mechatronics System) （P7）
机械体包括机架、机械联接和机械传动，它是机电一体化的基础，作用是支撑系统其他功能单元，传递运动和动力。和纯机械产品相比，一体化技术的性能和功能在机电系统中大幅提高，它要求机械本体适应在机械结构、材料、加工技术以及这些领域中的几何学下的新环境。相应的，新的一体化具有高效、多功能、可靠、节能、小轻和美学的令人赏心悦目的特征。
电子控制单元，也被称为控制单元（ECU）控制，是机电系统的核心，负责外部命令和传感器的信号输出。它集中、存储、计算并分析信息。基于信息处理的结果，按照一定的范围和步调发出命令来实现控制整个系统的目标。
5. It is put into a fairly standard machine tool that has had position sensing and motors on the control knobsinstalled. This is basically just a robot machinist. You usea rotating cutting tool to cut away all the metal that isn’t your crank. 3D metal etch-a-sketch, with the computer interpolating, so the circles come out to be pretty smooth. (CNC Machining) （P9）
1. The fundamental principle involved is the use of compressed air acting through a piston in a cylinder to set block brakes on the wheels. The action is simultaneous on the wheels of all the cars in the train. The compressed air is carried through a strong hose from car to car with couplings between cars; its release to all the separate block brake units, at the same time, is controlled by the engineer. (Braking Systems)（P5）
数控机床是复杂的机器，具有伺服机构和检测技术，它能在覆盖油膜状态下检测到0.005mm。数控机床至少有 6个马达（包括一些用来换刀具，一个或多个用来泵油和冷却液的各地方）。这些化成运行成本可能大大超过1美元/分钟。（电脑不再是成本的一个重要部分.）
7. Factory assembly line machinery is activated and monitored by a single PLC, where in the past hundreds of timers and relays would have been required to do the task. The machine orsystem user rarely, if ever, interacts directly with the PLC’s program. When it is necessary to either edit or create the PLC program, a personal computer is usually (but not always) connected to it. (What is a PLC?) （P61）
