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. 圖Figure 1.

Cimatron E 7.0教程 使用Cimatron E 起草應(yīng)用，建立部分或者組裝圖圖表是可能的，由2D 風景組成。在畫的每一個內(nèi)有一條或更多床單，起草的符號和注釋可能被增加并且編輯。 這些畫圖表包含象 起草標準那樣的具體的特性，意見歸因于，框架，模板等等。在各種各樣的起草的概念將的這個練習過程中沿著邊討論Cimatron E的動態(tài)的能力。 1、打開一份起草的資料 Open up the Drafting application within Cimatron E. 2、現(xiàn)在起草應(yīng)用的Cimatron 打開 資料在Cimatron E里使用起草被叫為一張畫。 有一條床單的一張畫被創(chuàng)造一份起草的資料自動創(chuàng) 造。 3、建立床單 一條床單包含一個一個模型，部分或者會議的2D 意見的布局。 除2D之外幾何學建立使用 sketcher，起草符號，注釋能被增加給床單。 無限的床單的數(shù)量能被歸入一張畫允許一象要求 的那樣安排許多意見。
