随着PLC与计算机技术的迅猛发展,图形化编程方法得到了越来越广泛的应用,尤其是梯形图（LAD）已成为现代PLC编程的主流方法。梯形图程序虽然简单易懂,但不能直观反映PLC程序执行过程,指令表（IL）编程方法则可以深入揭示PLC程序处理流程,为此,结合实例重点解析IL编程方法在PLC程序设计及应用中的基础地位。 相似文献

In this paper, we describe an operational methodology for characterizing the architecture of complex technical systems and demonstrate its application to a large sample of software releases. Our methodology is based upon directed network graphs, which allows us to identify all of the direct and indirect linkages between the components in a system. We use this approach to define three fundamental architectural patterns, which we label core–periphery, multi-core, and hierarchical. Applying our methodology to a sample of 1286 software releases from 17 applications, we find that the majority of releases possess a “core–periphery” structure. This architecture is characterized by a single dominant cyclic group of components (the “Core”) that is large relative to the system as a whole as well as to other cyclic groups in the system. We show that the size of the Core varies widely, even for systems that perform the same function. These differences appear to be associated with different models of development – open, distributed organizations develop systems with smaller Cores, while closed, co-located organizations develop systems with larger Cores. Our findings establish some “stylized facts” about the fine-grained structure of large, real-world technical systems, serving as a point of departure for future empirical work. 相似文献

Automatic software fault detection and repair is made possible by autonomic software recovery. By incorporating this function, the software will run more efficiently and aggressively while requiring much less time and resources for maintenance. The focus of this article is on a suggested automated approach to Software Fault Detection and Recovery. The Software Fault Detection and Recovery (SFDR) procedure identifies when a software component has been damaged due to a fault and then restores the damaged component so that the software can continue functioning normally. During the design process, the SFDR is examined and created independently from the intended program. The proposed technique was implemented into an application that demonstrates the SFDR's performance and effectiveness to guarantee its practicality in real-world scenarios. The results of this experiment were encouraging. Results from experiments and comparisons to prior works show that the proposed methodology is successful. 相似文献

The domain of transition studies has been drawing more and more scholarly attention and, as a result, its body of knowledge is rapidly growing. This raises new challenges as well as opportunities, not the least regarding the methodological and philosophical underpinnings of research in this domain. In this respect, transition research, as a relatively young field of inquiry, has been little concerned with methodological investigation and reflection. We propose a framework that enables this reflection: the so-called ‘transition research onion’. Subsequently, we utilize this framework to systematically assess 217 peer-reviewed papers in the field of transition studies, to distill key methodological patterns and trends of the field. The findings suggest that the methodology of transition studies, in terms of depth and diversity, is underdeveloped. These insights serve to guide future research on transition processes. 相似文献

There are many obstacles to effective open innovation in the public sector context, especially at the “fuzzy front end” (FFE), where the need or opportunity is known but serious resources have not yet been committed to possible solutions. In this paper, we report on a theoretically inspired and practically tested methodology for FFE public sector digital innovation. The methodology was purpose-built for the context and has been progressively refined using reflection-on-practice, but broadly consists of a hybrid of private sector open innovation practices, and agile software development processes. We outline the background, context, principles, stages and artefacts. Then we evaluate the method in terms of barriers and opportunities to FFE public sector innovation. We note that establishing the necessary context: a nurturing environment; cross-agency commitments in cash and in kind; and boundary spanning appointments, is as important to success as is the detailed execution of the method. 相似文献

The bond graph is a modelling and simulation tool, providing many possibilities. A methodology based on causal and behavioral bond graph analysis to build a dynamic icon model library in continuous thermofluid process is presented. The developed approach is implemented using SYMBOLS software and applied to a complex steam generator installation. The methodology given as assistant tool, is proposed so that the industrial designer can easily build a thermofluid model of most technological processes. 相似文献
