9、ernal I / O port expansion I / O interface and the memory addresses of three major components, CPU core is formed by one or more accumulators, which have the logical math capabilities, and can read the contents of the program memory to drive through the calculation of the corresponding memory and I

10、/ O interface; I / O port to the internal accumulator and external input and output systems together, and the relevant data stored in the program memory or data memory; memory can be I / O port input data stored in memory and transferred to the accumulator at work, and I / O interfaces, memory sub-R

11、OM program memory and data memory RAM, ROM data can be permanently stored in memory, CPU and RAM only as a temporary calculated using the calculation buffer space. PLC immunity is extremely good, we do not have to care about the life and work of its harsh occasions, all of these issues are no longer

12、 the subject of our failure, and left us is concerned with how to take advantage of the PLCs internal resources to strengthen our ability to control the device, so that our equipment is more flexible.PLC language is not what we imagine the assembly language or C language programming, instead of usin

13、g the existing relay control of the ladder, making an electrical engineer in the preparation of the program is very easy to understand the language of the PLC, and many non- Electrical professionals and in-depth understanding of the PLC quickly. PLC communication has become increasingly reflect its

14、value, in the communication between the PLC and the PLC, through information, communication and data sharing to ensure coordination between devices, has reached a complementary effect. PLC data transfer only the internal data to the other side of a consecutive addresses, we called it a table, the ot

15、her PLC by reading data in the table to operate. The transmission of information has serial and parallel port lines of the points: the usual PLC is 8 machine, of course, there are 16 machines. When we send the data transmission can be a one to the other, you can also eight 8-bit send data to each ot

16、her, one and eight difference is what we call the serial port and parallel port to send data to send data. Serial port speed is relatively slow, but as long as two or three port lines will solve the problem, and can use the phone line for remote control. The parallel port transmission speed is very

17、fast, which is 256 times the serial port, a short distance advantage, because it is TTL level, generally limited to one meter range, it does not apply to long-distance data transmission, so the cost is too expensive.Many cases, we always like to use string and conversion chip for transmission, in wh

18、ich case we do not need to be overly complex register set, and direct data transfer instruction through the exchange of data, but not a very viable communication approach, because the transmit data when the PLC must have been waiting for the other side of your data output, it can not do other work.W

19、hen you are reading a book, when you hear someone knocking at the door, you stop the hands of things, play to open the door, and knock on the door with a dialogue, this time the phone rings, you answer the phone schematically in take calls, back to knock on the door to continue with the dialogue, ha

20、s been completed, you then continue to read your book, in which case we call it an interrupt, it has authority, also has priority, PLC have this kind of functionality. It is characterized by the operation of the device is that we may encounter during emergency incidents, we have to stop immediately

21、the task at hand, to deal with more important things, this situation is that we often encounter, PLC to perform tasks in an emergency, always first save the current state, such as the programs address, CPU accumulator data, like when we went to open the door to note we are looking at the first few p

22、ages of the book or simply to make a sign, because we will have to continue to be followed to see the back of the book.CPU always in accordance with the wishes we should do, but you give it a wrong thing, it will do the same, which we must pay attention.Interrupt is not the only one, sometimes exist

23、 several interrupt, the interrupt priority level with them according to the persons request to perform higher-level interrupts. This will form the interrupt interrupt interrupt nesting. Of course, the level of disruption inside the PLC CPU based on a variety of resource-related, but also with the ca

24、pacity of the stack size are also related.When we finished work a workpiece, a signal to the PLC, the PLCs internal counter is incremented by one to calculate the workload of our day, a simple counter to solve the problem, of course, they can also be kept in case of power failure data , prompting th

25、e data is not lost, it is our desire.PLC also has advanced features counter, when we accept some of the high-speed data, high speed mentioned here is in the microsecond-level data, such as bar code scanners constantly scan data, high-speed signal processor (DSP) calculated and so on, we will adopt t

26、o advanced counters to help us count. It is in the PLC program is executed once found senior counter corresponding interrupt, it will immediately put his work. After re-programming of the ladder program that we advanced in the implementation of the program counter will automatically perform the corr

PLC has been around for a

29、 full impact on the generations, we have the experience from the previous generation to get more knowledge and lessons learned, to continue the development of PLC technology, to bring it to a higher tide.中文资料可编程控制器技术讨论与未来发展随着时代的发展,当今的技术也日趋完善、竞争愈演愈烈;单靠人工的操作已不能满足于目前的制造业前景,也无法保证更高质量的要求和高新技术企业的形象.人们在生产实

30、践中看到,自动化给人们带来了极大的便利和产品质量上的保证,同时也减轻了人员的劳动强度,减少了人员上的编制.在许多复杂的生产过程中难以实现的目标控制、整体优化、最佳决策等,熟练的操作工、技术人员或专家、管理者却能够容易判断和操作,可以获得满意的效果.人工智能的研究目标正是利用计算机来实现、模拟这些智能行为,通过人脑与计算机协调工作,以人机结合的模式,为解决十分复杂的问题寻找最佳的途径PLC的最大特点在于：电气工程师已不再电气的硬件上花费太多的心计，只要将按钮开关或感应器的输入点连接到PLC的输入点上就能解决问题，通过输出点连接接触器或继电器来控制大功率的启动设备，而小功率的输出设备直接连接就可以

31、。PLC的内部包含了具有中央处理器的CPU，并带有外部I/O口扩展的I/O接口地址和存储器三大块组成，CPU的核心是由一个或者多个累加器组成，它们具有逻辑的数学运算能力，并能读取程序存储器的内容通过计算后去驱动相应的存储器和I/O接口；I/O口将内部累加器和外部的输入和输出系统连接起来，并将相关的数据存入程序存储器或者数据存储器中；存储器可以将I/O口输入的数据存入存储器中，并在工作时调转到累加器和I/O接口上，存储器分程序存储器ROM和数据存储器RAM,ROM可以将数据永久的存入存储器中，而RAM只能作为CPU计算时临时计算使用的缓冲空间。PLC的抗干扰是极其优秀的，我们根本不用去关心它的使

32、用寿命和工作场合的恶劣，这些所有的问题已不再成为我们失败的主题，而留给我们的是关心如何来利用PLC的内部资源为我们加强设备的控制能力，使我们的设备更加的柔性。PLC的语言并不是我们所想象的汇编语言或C语言来进行编程，而是采用原有的继电器控制的梯形图，使得电气工程师在编写程序时很容易就理解了PLC的语言，而且很多的非电气专业人士也对PLC很快认识并深入。PLC的通信已经愈来愈体现它的价值，在PLC与PLC之间的通信，能够通过信息的沟通和数据的共享来保证设备之间的相互协调，已达到互补的效果。PLC的数据传送只是将内部的数据传送到对方的一块连续的地址中，我们把它称为一个表，对方的PLC通过读取表中的

33、数据来进行操作。信息的传送口线有串口和并口之分：通常的PLC是8位机，当然也有16位机。我们在发送数据的时候可以是一位一位的发送给对方，也可以8位8位的将数据发送到对方，一位和8位区别也就是我们所说的串口发送数据和并口发送数据。串口速度比较慢，但只要两条或者三条口线就能解决问题，并能借用电话线来进行远程控制。而并口的传送速度是极快的，它是串口的256倍，在短距离占有优势，由于是TTL电平，一般限于1米的范围，它并不适用于长距离的数据传送，这样成本太昂贵了。很多的情况下我们总喜欢采用串并转换芯片来进行传输，这种情况下不需要我们进行过于复杂的寄存器设置了，而直接通过数据传送指令进行数据交流，但在通

34、信中并不是一个十分可行的办法，因为在发送数据的时候对方的PLC必须一直等待你的数据输出，它不能去做其他的工作。当你在看书的时候，你听到有人敲门、你停下手上的事情、去打开门、并同敲门者对话、这个时候电话响了、你示意接个电话、在接完电话后、回过头来同敲门者继续对话、对话完毕后、你再继续看你的书，这种情况我们把它称为中断，它具有权威性，也具有优先性，PLC具备了这样的功能。它的特点在于我们在设备的操作过程中可能会遇到紧急的突发事件，我们要立刻的停下手上的工作，去处理更重要的事情，这种情况是我们经常所遇到的，PLC在去执行紧急的任务时，总会先保存目前的状态，比如程序的地址，CPU的累加器数据等，就像我

35、们去开门时要记下我们看的书在第几页了或者干脆作个记号，因为我们待会还要继续接着看后面的书。CPU总是按照我们的意愿去做应该做的事情，但你错误的给它一件事情，它也会同样的去做，这一点我们必须注意。中断并不是只有一个，有时会同时存在几个中断，中断具有优先的级别，他们会根据人的要求去执行更高级别的中断。这种中断中的中断也就形成了中断嵌套。当然中断的级别根据各种PLC内部CPU的资源有关，同时也跟堆栈的容量大小也有关系。当我们在工作完一个工件时，给PLC一个信号，将PLC的内部计数器加1来计算我们一天的工作量时，一个简单的计数器能解决问题，当然它们也能够在掉电的情况下保持数据，促使数据不丢失，这也是我

36、们所渴望的。PLC还具有高级计数器的功能，当我们在接受一些高速的数据时，这里所说的高速是在在微秒级的数据，比如条码扫描机在不断的扫描数据，数据处理器DSP计算的高速信号等，我们就要采用到高级计数器来帮助我们进行计数。它在PLC执行程序时一旦发现高级计数器对应的中断，就会立即放下手上的工作。经过再次编程的梯形图程序说明我们在执行程序时高级计数器会自动的执行对应的工作，从而将高级计数器的级别升至高一级别。PLC的发展已经从单一的模式进入了通信的网络时代，并同其它的工控网板和I/O卡板轻易的进行共享。组态软件可以将所有的这些硬件连接起来，通过更直观的动画图片来进行控制，并可以通过互联网在异地进行控制

37、，像神舟五号的发射就是采用这种办法来使飞船升空。更高层次的发展需要我们不断的努力来取得。PLC的出现已经足足影响了几代人，我们也从上一辈的经验中获取了更多的知识和教训，来不断的发展PLC技术，将它推向更高浪潮。公司档案管理制度一、总则1、为加强本公司档案工作，充分发挥档案作用，全面提高档案管理水平，有效地保护及利用档案，为公司发展服务，特制定本制度。2、公司档案，是指公司从事经营、管理以及其他各项活动直接形成的对公司有保存价值的各种文字、图表、声像等不同形式的历史记录。公司档案分为受控档案和非受控档案。3、公文承办部门或承办人员应保证经办文件的系统完整(公文上的各种附件一律不准抽存)。结案后及
