可重构系统最突出的优点就是能够根据不同的应用需求，改变自身的体系结构，以便与具体的应用需求相匹配。面对市场的千变万化，如何使制造系统快速而经济地响应市场需求的变化，是对当今制造业的一个巨大挑战。传统的机械自动化生产线具有批量生产的效益，但面对市场的变化不能快速响应；而柔性制造系统虽能缩短产品的试制和生产周期，但投资巨大，回收周期长。因此，迫切需要建立一种既具有规模生产的效益，又能快速适应动态多变的制造环境，并能充分利用现有制造资源的新型制造模式。对此，新近提出的可重构制造系统是适应这一需求的一条有效途径。

工控软件的发展同样是自动化技术发展的重要方面。自上世纪90年代起，IBM接连收购了一系列中间件厂商，使中间件成为了企业IT架构的核心，也让人们逐渐认识到软件的重要性及其核心地位。之后，IBM又陆续收购了一些知名的软件企业，如Lotus、DB2．软件开始与硬件齐头并进，而在2004年IBM进一步将PC业务卖给联想，此事件向人们昭示：属于硬件的辉煌时代已成为历史，软件发生高潮的时代已经到来。而在工业控制领域里面，硬件软件化就是一种发展趋势。如嵌入式软PLC的出现等。目前，市场上德国三S软件公司首推的最新版本CoDeSysV3.5软件（基于CoDeSys平台下的嵌入式系统软PLC）。倡导以“可复用”为宗旨的“开放式、可重构的自动化”理念。该软件是靠IEC61131的开发环境，支持梯形图、流程图、结构图、高级ST语言等自动控制工业标准的几种语言。

在过去的15年里，在开发具有新销设计的链条方面取得了进步。一家国内制造商正在生产一种被称为“光滑链环”的链条系列，这种链条具有抛光销，在长期使用后磨损最小。与旧设计相比，一个显著的变化是链条带有一个销，可以旋转到三个不同的位置，每次120度，使正常磨损寿命增加一倍。今天的涂层是普通的、抛光的、锌的、黄锌的以及现在具有更好耐磨性能的不同合金。不锈钢结构也有显著改进，最新的不锈钢链条是X248，取代了早已过时的电缆输送机。这种新的2英寸节距链将处理海拔变化和转弯，比历史上每个吊耳或大约每12英寸磨损一次的锚链好得多。

The most outstanding advantage of reconfigurable system is that it can change its own architecture according to different application requirements in order to match the specific application requirements. Facing the ever-changing market, how to make the manufacturing system respond to the changes of market demand quickly and economically is a great challenge to today's manufacturing industry. The traditional mechanical automation production line has the benefit of mass production, but it can't respond quickly to market changes; Although flexible manufacturing system can shorten the trial production and production cycle of products, it has huge investment and long recovery cycle. Therefore, it is urgent to establish a new manufacturing model that not only has the benefits of large-scale production, but also can quickly adapt to the dynamic and changeable manufacturing environment and make full use of existing manufacturing resources. In this regard, the newly proposed reconfigurable manufacturing system is an effective way to meet this demand.

The development of industrial control software is also an important aspect of automation technology development. Since the 1990s, IBM has successively acquired a series of middleware vendors, making middleware the core of enterprise IT architecture, and making people gradually realize the importance and core position of software. After that, IBM successively acquired some well-known software companies, such as Lotus and DB2．. Software began to go hand in hand with hardware, and in 2004, IBM further sold its PC business to Lenovo. This event showed people that moderns, which belongs to hardware, has become history, and the era of software climax has arrived. In the field of industrial control, hardware software is a development trend. Such as the emergence of embedded soft PLC. At present, the latest version of CoDeSysV3.5 software (based on embedded system soft PLC under CoDeSys platform) first promoted by German Sans Software Company in the market. Advocate the concept of "open and reconfigurable automation" with the purpose of "reusability". The software is based on the development environment of IEC61131, and supports several languages of automatic control industrial standards such as ladder diagram, flow chart, structure diagram and advanced ST language.

The initial value must be set to 0 to ensure that the input variable transmits the value 0 to the user program in case of failure. The 8502-BI-DP module activates the error indicator light on the front panel. The module must be installed on the appropriate connector board to run. If the FTA requires system cables to connect the connector board to the FTA. Connector board, system cable and FTA are not included in the scope of delivery.

In the past 15 years, progress has been made in developing chains with new pin designs. A domestic manufacturer is producing a series of chains called "smooth links", which have polished pins and have the least wear after long-term use. Compared with the old design, a remarkable change is that the chain has a pin, which can rotate to three different positions, 120 degrees each time, so that the normal wear life is doubled. Today's coatings are common, polished, zinc, yellow zinc and different alloys with better wear resistance now. The stainless steel structure has also been significantly improved. The latest stainless steel chain is X248, which has replaced the outdated cable conveyor. This new 2-inch pitch chain will handle altitude changes and turns, which is much better than the anchor chain that has worn every lug or about every 12 inches in history.
