Other PLC fixed communication data storage addresses are inconvenient for application. S7-1200 can define different data addresses for different sub stations.



Some PLC communication instruction packages such as Omron or delta fix the data read by each communication in a specific register. When you want to use it, you can "transfer" it out of this register for use. This always means that when PLC reads different data of the same equipment or different equipment, you must "plan" to "move" the data you need from the public fixed data register "accurately" and "timely" according to different times, otherwise the public fixed data register may be replaced by "new" data refresh, resulting in data confusion. To complete these tasks, you must have good programming habits and write a lot of programs for timing processing. If the amount of data is large, it is definitely a test for an engineer.



S7-1200 is much more flexible in this regard. You can put the data you read into any defined data background data block, which is very easy and simple. 0近新能源汽车和锂电池生产线的话题非常火爆，国内锂电大厂宁德时代加速布局海外市场，0近宣布了计划投资73.4亿欧元（相当于500亿人民币），在匈牙利建设0二座欧洲工厂，生产新能源锂电池，以供应欧洲市场的新能源汽车。之前也有消息说，宁德时代计划投资50亿美元在北美建厂，因为各种敏感性问题，北美计划暂时被搁置。0对值编码器在新建生产线上可以起到什么作用？

      据了解宁德时代公司目前在全球有十大生产基地，早在2018年宁德时代就宣布0一家海外工厂设立在德国图林根州，但是目前来看德国工厂的反馈意见，就是成本太高和建设周期太长，考虑到目前的国际形势，海外建设周期过长可能到投产时就已经减弱了市场竞争力。

      所以无论是匈牙利建厂还是计划北美建厂，甚至在国内建新厂，因疫情和进口涨价的因素，新建生产线都面临着同样问题：

出差要少，调试周期要短，一次通过率要高，使用维护要简单方便，要快速出产能。 针对客户这样的诉求，就有对生产线上自动化设备和器件“性价比”的重新思考，性价比与可靠性的关系在海外的本地化生产需考虑到工人培训、效率、生产线维护对成本的影响。



      0近小米的雷军在演讲中也有相似的表述，其实产品技术先进性，也是要为提高产品性价比服务的。客户既有对技术先进性的追求，可持续发展，又有对于生产线投入产出成本及今后使用成本的考量。面对太新的技术，却感觉成本太高；面对一些把便宜就当作性价比的产品，对于其稳定性可靠性又难以信任。在“先进技术”与“性价比”这两者之间如何做出选择？

可见“技术为本，性价比为纲”已是科技大佬们共同思考的问题。   无论是海外建厂还是国内新建生产线，生产线上设备如何考虑性价比和可靠性?中国制造的自动化设备在海外的生产线上能占多少比重?如何降低采用进口器件受涨价因素和货期因素的影响?上海0浦编码器已有多年随着设备出口欧洲的经验，也有国内参与自动化生产线建设应用的经验，那么我们的0对值编码器在生产线上起什么样的作用呢?
0对值编码器的加入，就可以帮助客户减少对于“可靠性”与“使用成本”的担忧。

首先就从我们编码器的角度来讲，新建生产线至少有这么几点是需要考虑的：
0一点、性价比

0二点、调试周期

0三点、可靠性

0四点、工人培训

0五点、后期维护的便利性
      生产线的稳定、可靠、高效，是直接影响企业效益的，0近宁德时代董事长曾毓群在世界动力电池大会上也提到3点要求：“0一是对研发能力提出更高的要求;0二是大规模交付对制造能力提出更高的要求;0三是产业纵深发展对服务能力提出更高要求。”这其中0二点就是针对制造能力的，现代的工业生产已经不再是单机设备加工了，是需要整个生产过程实现完全的自动化，任何的自动化生产线无论技术先进与否，都要围绕着稳定、可靠、高效的目标去实行。

那么我们认为，生产线上的性价比应该是如下的理解   接下来以锂电生产线为例，在各类车用锂电池制造设备中，一提到制造能力的先进高效，往往会想到各种伺服电机作为执行元器件的控制系统，但是由于电池的制造工艺，在各种生产工序中并非都是由伺服电机来完成，也有部分是步进电机甚至是气缸，比如辊压就是有气缸定位的。

     在传统的伺服中，编码器是作为电机末端的传感，各个机位同步就需要接收来自编码器实时位置反馈，控制器通过工业总线或者工业以太网串联，逐个扫描位置数据，即使再快的总线和再快的PLC也会存在些许延时，这就需要专业的伺服技术人员现场调试，有时候设备使用时间久了，机械磨损损耗较大，机械磨损后定位位置发生改变，还需要专业技术人员现场调整和维护，在电池生产线大批量产能需求下，使用成本和维护成本就增加了。 在机械终端加0对值编码器，作为前端传感，位置数据直接并联输出到控制器，同步采集，无论有多少个点同时工作，也无论是采用气缸或者步进电机驱动，都可以实现不同执行器间协同工作，而且不需要繁琐的调试，只需要手动校准，把位置值写入控制器，控制器运行时读到数值输出开关点，控制机器，工作效率显著提高，更加稳定可靠，现场调试简单，且后期维护也方便这里提到开关点，有懂技术的会说用光电开关定位，但是在电池生产线上比如焊头、比如压辊是柔性的，只靠一两个开关点显然不能满足0确定位的要求，而且一旦过冲还会损坏设备，所以需要柔性的传感器方案，单圈0对值编码器就被当作“柔性电子凸轮开关”使用。 我们把单圈0对值编码器简单理解为360度里面有很多个位置开关组合，假设把360度分成360个开关点编码，控制设备(比如PLC或单片机)接收到编码，可以根据需要选择这360个位置中任意位置作为电子凸轮的输出开关点，作为“凸轮进-减速”输出和“凸轮出-复归位”输出，来控制机械装置周而复始的往复工作。  这种柔性的电子式凸轮开关0度高、重复性高、可靠性高，在多个位置上可以有多个凸轮开关点，根据需要任意位置编程输出，非常适合只需简单重复而又要求可靠的应用，就如在锂电的焊接和封装生产线上那简单重复的工序要求。

      有了0对值编码器，调试的时候只需要手动锁定几个点的位置，然后在PLC程序里面记入位置值，以后就不会再改变，编程与调试非常简单，后期使用也能保证长期可靠。 关于0对值编码器输出信号，因为大多数工控设备都会用到模拟量接口，模拟量采集模块是同时采集所有输入信号，同步性高、兼容性好，而且现场检查故障只需要一只万用表非常方便，所以4-20mA信号的模拟量信号的单圈0对值编码器具有接线简单、读数简单、调试简单、检修简单诸多优点，在0度要求不高可靠性要求极高的场合下，反而受到现场工程师们的偏好。

      由于锂电生产线空间有限，需要传感器体积小，又是连续高速焊接，一方面周边会产生较高环境温度，另一方面焊机位置靠得近，相互之间会产生较高的电磁干扰，所以对传感器提出以下更高的要求：

1.体积较小
2.抗周边电磁干扰
2.0度较高
3.高重复性
4.高可靠性
5.耐较高温度，较长使用寿命 在当前的自动化设备使用伺服电机控制已经成为一种先进的潮流，设备自动化必须高效，而且简单可靠。如果搞得技术复杂了，调试周期长，维护服务都麻烦。而简单高效、可靠耐用的电子凸轮类型的编码器，在工厂自动化设备上越来越受欢迎，这种简单重复性的自动化加工，就交给0对值编码器与一般PLC，就能轻松搞定了0对值数字码盘，内置信号转换，4～20mA模拟电流与RS485双输出，方便连接各品牌PLC及上位机设备。

非接触式工作原理，耐潮湿、抗振动，高0度数字化，替代增量型编码器和电位器,助力产业升级

通过电脑端EasyPro软件可设定：4mA对应值、20mA对应值任意设定及微调，方向设定，外部置位线设定预设位置(如中点置位)，直接对应单圈角度测量，安装方便，无需找零。

General electric company designed the processor / controller of is220ucsah1amark vie system.



This is a single box assembly with a front panel for communication connection, two screws mounted on the rear edge, and three grille holes for ventilation. The controller is designed to be installed at the bottom of the cabinet. For a small setup that is easy to service a triple redundant system, up to three components can be installed side by side. Sensor output mechanical angle θ The signal enters the CTR main control board from the system interface XIO board, and is converted into θ r. Then at the rotor angular velocity ω R form, directly feed back the speed to the speed regulator.



Torque given (T)_ R will come from SFC of speed regulator_ T_ R performs torque limit processing and di / dt calculation to obtain the final torque reference IQ_ R signal. ID_ R is the magnetic flux given signal, which has the following functions: keep the magnetic flux constant below the base speed, and adjust the speed of the motor with constant torque; Above the base speed, keep the voltage constant, reduce the magnetic flux in a certain proportion, and adjust the speed with constant power.



After the vector calculation control system completes the IGBT trigger signal, the processor main board transmits the trigger pulse to the inverter to control the IGBT on and off, so as to obtain the input voltage and frequency of the required motor approximate to the sine wave, and then adjust the motor speed.

The fl-net network takes Ethernet as the physical layer and adopts the bus topology structure. It is a PLC network standard adopted by Japan. The high layer of the protocol stack is UDP / IP + UDP / IP + single loop communication protocol to ensure the real-time communication.



The data exchange between the PLC system and the transmission system is based on the Ethernet global data processing communication (EGD). The EGD protocol is the data exchange protocol based on the Ethernet technology of Ge automation company of the United States. It realizes the high-speed transmission of 100Mbps data between one sender and multiple senders in the form of data packets, and follows the UDP / IP single loop communication protocol. The data transmission time interval is short, the security is strong, and it is not easy to lose. Each station is a two-way role, which is both a server and a client.



3. System commissioning



It can be seen from Fig. 5 that this is a typical double closed loop control system. Tmd-10e2 provides a variety of debugging means, from static motor self-test to load debugging, with the purpose of ensuring the stability and rapid response of the system.



3.1 fully meet the requirements of real-time acquisition and control





Other PLC fixed communication data storage addresses are inconvenient for application. S7-1200 can define different data addresses for different sub stations.





Some PLC communication instruction packages such as Omron or delta fix the data read by each communication in a specific register. When you want to use it, you can "transfer" it out of this register for use. This always means that when PLC reads different data of the same equipment or different equipment, you must "plan" to "move" the data you need from the public fixed data register "accurately" and "timely" according to different times, otherwise the public fixed data register may be replaced by "new" data refresh, resulting in data confusion. To complete these tasks, you must have good programming habits and write a lot of programs for timing processing. If the amount of data is large, it is definitely a test for an engineer.





S7-1200 is much more flexible in this regard. You can put the data you read into any defined data background data block, which is very easy and simple. Recently, the topic of new energy vehicles and lithium battery production lines has been very hot. Ningde times, a large domestic lithium battery manufacturer, has accelerated the layout of overseas markets. Recently, it announced that it plans to invest 7.34 billion euros (equivalent to 50 billion yuan) to build a second European plant in Hungary to produce new energy lithium batteries to supply new energy vehicles in the European market. It has also been reported that Ningde times plans to invest US $5 billion to build a plant in North America. Due to various sensitive issues, the North American plan has been temporarily shelved. What role can absolute value encoder play in the new production line?



It is understood that Ningde times currently has ten production bases in the world. As early as 2018, Ningde Times announced that its first overseas factory was set up in Thuringia, Germany. However, at present, the feedback of German factories is that the cost is too high and the construction cycle is too long. Considering the current international situation, the long overseas construction cycle may have weakened the market competitiveness when it is put into production.



Therefore, whether it is a factory in Hungary, a factory in North America, or even a new factory in China, the new production line is faced with the same problems due to the epidemic and import price rise:



Less business trips, shorter commissioning cycle, high one-time pass rate, simple and convenient use and maintenance, and rapid production. In response to such demands of customers, there is a rethinking of the "cost performance" of automation equipment and devices on the production line. The relationship between cost performance and reliability. The impact of worker training, efficiency and production line maintenance on costs needs to be considered in overseas localization production.





Lei Jun of Xiaomi also made a similar statement in his speech recently. In fact, the progressiveness of product technology is also to improve the cost performance of products. Customers not only pursue the progressiveness technology and sustainable development, but also consider the input-output cost of the production line and the future use cost. Facing too new technology, they feel that the cost is too high; It is difficult to trust the stability and reliability of some products that regard cheap as cost-effective. How to choose between "advanced technology" and "cost performance"?



It can be seen that "technology-based, cost-effectiveness oriented" has been the common thinking of science and technology leaders. Whether it is an overseas factory or a new domestic production line, how to consider the cost performance and reliability of the equipment on the production line? What is the proportion of automation equipment made in China in overseas production lines? How to reduce the impact of price rise and delivery time on the use of imported devices? Shanghai Jingpu encoder has many years of experience in exporting equipment to Europe, as well as domestic experience in the construction and application of automatic production lines. What role does our absolute value encoder play in the production line?

The addition of absolute value encoder can help customers reduce their worries about "reliability" and "use cost".



First of all, from the perspective of our encoder, there are at least the following points to consider for the new production line:

First, cost performance



Second, commissioning cycle



Third, reliability



Fourth, worker training



Fifth, convenience of later maintenance
