This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.

Cimatron E 7.0教程 使用Cimatron E 起草应用，建立部分或者组装图图表是可能的，由2D 风景组成。在画的每一个内有一条或更多床单，起草的符号和注释可能被增加并且编辑。 这些画图表包含象 起草标准那样的具体的特性，意见归因于，框架，模板等等。在各种各样的起草的概念将的这个练习过程中沿着边讨论Cimatron E的动态的能力。 1、打开一份起草的资料 Open up the Drafting application within Cimatron E. 2、现在起草应用的Cimatron 打开 资料在Cimatron E里使用起草被叫为一张画。 有一条床单的一张画被创造一份起草的资料自动创 造。 3、建立床单 一条床单包含一个一个模型，部分或者会议的2D 意见的布局。 除2D之外几何学建立使用 sketcher，起草符号，注释能被增加给床单。 无限的床单的数量能被归入一张画允许一象要求 的那样安排许多意见。
