模块一次添加一个到配置中选择参数以应用于模块的所有通道。可以选择逻辑模块来提供HART状态和过程Profibus-DP循环输入电报中的变量。此外,对于需要访问许多HART变量的应用可以使用HART“邮箱”。该技术收集HART变量根据需要;节省电报中的空间数据工作过度。此方法仅在使用时可用参数化。
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。

Modules add parameters to the configuration one at a time to apply to all channels of the module. Logic modules can be selected to provide variables in the HART status and process Profibus-DP loop input telegram. In addition, the HART "mailbox" can be used for applications that need to access many HART variables. This technology collects HART variables as needed; Saving space in telegrams is overworked. This method can be parameterized only when used.
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.
