1756-A7/B邏輯順序模塊

工業(yè)以太網(wǎng)（Industrial Ethernet）以及現(xiàn)場總線（fieldbus）技術(shù)的確是一個(gè)非常好的選擇，為生產(chǎn)效益提升所貢獻(xiàn)的綜效（synergy），這是每一位制造業(yè)的朋友們都有目共睹的。在汽車制造行業(yè)中，由于近幾年來國際的大型投資項(xiàng)目進(jìn)入到中國市場，尤其是日本的三大汽車公司的項(xiàng)目。身為汽車行業(yè)應(yīng)用解決方案的領(lǐng)頭品牌，歐姆龍系統(tǒng)方案正在各個(gè)項(xiàng)目中展開，包括生產(chǎn)執(zhí)行系統(tǒng)（MES），設(shè)備監(jiān)控管理系統(tǒng)(FMCS)，情報(bào)訊息系統(tǒng)(RFID, 2-Dimension Code, BCR)，無線生產(chǎn)資料通訊系統(tǒng)(WT30,WD30)等。拿歐姆龍的現(xiàn)場總線來說，它是基于DeviceNet的平臺而構(gòu)建起來的。當(dāng)然，以DeviceNet身為一個(gè)符合中國國家現(xiàn)場總線標(biāo)準(zhǔn)的解決方案的立場而言，對于各個(gè)相關(guān)的工業(yè)領(lǐng)域的應(yīng)用，包括汽車，半導(dǎo)體，液晶，化工，鋼鐵，石油，食品等等行業(yè)，DeviceNet的確扮演著非常重要的角色。DeviceNet的解決方案（產(chǎn)品）除了PLC之外，還有相當(dāng)多的傳感器，控制元件，運(yùn)動單元，配合著歐姆龍的Control Link 控制方案，可以非常整體（integrated）地來滿足所有工業(yè)界應(yīng)用的需求。二、工業(yè)控制網(wǎng)絡(luò)將向有線和無線相結(jié)合方向發(fā)展。有線局域網(wǎng)以其廣泛的適用性和技術(shù)價(jià)格方面的優(yōu)勢，獲得了成功并得到了迅速發(fā)展。然而，在某些工業(yè)的生產(chǎn)現(xiàn)場，由于工業(yè)環(huán)境禁止、限制使用電纜或很難使用電纜，有線局域網(wǎng)很難發(fā)揮作用，因此無線局域網(wǎng)技術(shù)得到了發(fā)展和應(yīng)用。隨著微電子技術(shù)的不斷發(fā)展，無線局域網(wǎng)技術(shù)將在工業(yè)控制網(wǎng)絡(luò)中發(fā)揮越來越大的作用。因此，關(guān)于無線方案的應(yīng)用，在目前的市場需求環(huán)境之中是非常巨大的，包括個(gè)人的生活需求，商業(yè)環(huán)境需求，和生產(chǎn)制造環(huán)境的需求。由于無線應(yīng)用解決方案的出現(xiàn)，為大家?guī)砹藷o數(shù)的方便性和靈活性。但是，特別是在工業(yè)生產(chǎn)的需求領(lǐng)域之中，假如無線的需求方案無法提供一個(gè)可信賴的，安全的操作實(shí)用性的時(shí)候，無線的解決方案就會變成一種危險(xiǎn)的問題狀況。無線網(wǎng)絡(luò)的方案，在制造行業(yè)的生產(chǎn)現(xiàn)場里，可以讓一個(gè)工廠變得更靈活，更方便。譬如說：在工廠的設(shè)備安裝的平面規(guī)劃時(shí)的柔性，在工廠的設(shè)備安裝面積利用率的提升，在工藝流程改造和移動時(shí)的簡單性……等等。當(dāng)然，無線通訊的安全完全被保證，必須根據(jù)國家規(guī)范來加以限制，這是基本的條件。歐姆龍的工業(yè)領(lǐng)域無線方案在汽車制造行業(yè)中應(yīng)用廣泛，特別是，例如用于生產(chǎn)情報(bào)的安東（Andon）系統(tǒng)，和其他的汽車生產(chǎn)現(xiàn)場的特別應(yīng)用場所。此外，歐姆龍的工業(yè)級無線應(yīng)用方案（WT30，WD30），可方便地、快速地構(gòu)建起“無線DeviceNet現(xiàn)場總線”的系統(tǒng)。目前，各大日本汽車生產(chǎn)工廠已經(jīng)都采用了歐姆龍公司的方案。三、PLC的發(fā)展方向和其他特殊應(yīng)用方案趨勢。長期以來，PLC始終處于工業(yè)控制自動化領(lǐng)域的主戰(zhàn)場位置，為各種各樣的自動化控制設(shè)備提供非?？煽康目刂品桨福c
DCS
和工業(yè)PC形成了三足鼎立之勢。目前，國內(nèi)PLC市場仍以國外產(chǎn)品為主，如歐姆龍、Siemens、Modicon、A-B、三菱、GE的產(chǎn)品。雖然國內(nèi)也有大約30家的生產(chǎn)廠商，但是目前都尚未到達(dá)足夠的生產(chǎn)規(guī)模。據(jù)專家估計(jì)，從2000年P(guān)LC的國內(nèi)市場銷量為15~20萬套（其中進(jìn)口占90%左右），約25~35億元人民幣，年增長率約為12%。預(yù)計(jì)到2005年全國PLC需求量將達(dá)到25萬套左右，約35~45億元人民幣的規(guī)模。同時(shí)，PLC市場的變化也反映了全世界制造業(yè)的狀況，2000后大幅度下滑。但是，按照Automation Research Corp的預(yù)測，盡管全球經(jīng)濟(jì)下滑，PLC市場將會復(fù)蘇，估計(jì)全球PLC市場在2000年為76億美元，到2005年底將回到76億美元，并繼續(xù)略微增長。基本上，體積微型化、網(wǎng)絡(luò)化、PC化和開放性是PLC未來發(fā)展的幾個(gè)主要的方向。但是，隨著軟PLC（Soft PLC）控制組態(tài)軟件的進(jìn)一步完善和發(fā)展，安裝有軟PLC組態(tài)軟件和PC-based控制的市場份額也將逐步得到增長。Industrial Ethernet and fieldbus technology are indeed a very good choice. It is obvious to everyone in the manufacturing industry that they contribute to the improvement of production efficiency. In the automobile manufacturing industry, as large international investment projects have entered the Chinese market in recent years, especially the projects of the three major automobile companies in Japan. As a leading brand of application solutions in the automotive industry, Omron system solutions are being developed in various projects, including production execution system (MES), equipment monitoring management system (FMCS), information information system (RFID, 2-Dimension Code, BCR), wireless production data communication system (WT30, WD30), etc. Take Omron's fieldbus as an example. It is built on the platform of DeviceNet. Of course, from the standpoint of DeviceNet as the first solution conforming to China's national field bus standard, DeviceNet does play a very important role in the application of various related industrial fields, including automobile, semiconductor, liquid crystal, chemical, steel, petroleum, food and other industries. In addition to PLC, DeviceNet's solutions (products) also have quite a few sensors, control elements, and motion units. Together with Omron's Control Link control scheme, DeviceNet can meet the needs of all industrial applications in a very integrated way. 2、 The industrial control network will develop towards the combination of wired and wireless. Wired LAN has been successful and developed rapidly because of its wide applicability and advantages in technology and price. However, in some industrial production sites, because the industrial environment prohibits or restricts the use of cables or it is difficult to use cables, wired LAN is difficult to play a role, so wireless LAN technology has been developed and applied. With the continuous development of microelectronics technology, wireless LAN technology will play an increasingly important role in industrial control networks. Therefore, the application of wireless solutions is very huge in the current market demand environment, including personal living needs, business environment needs, and production and manufacturing environment needs. The emergence of wireless application solutions has brought us countless conveniences and flexibility. However, especially in the demand field of industrial production, if the wireless demand solution cannot provide a reliable, safe and practical operation, the wireless solution will become a dangerous problem. The wireless network solution can make a factory more flexible and convenient in the production site of the manufacturing industry. For example, flexibility in plane planning of equipment installation in the factory, improvement in utilization of equipment installation area in the factory, simplicity in process flow transformation and movement, etc. Of course, the security of wireless communication is completely guaranteed and must be restricted according to national regulations, which is the most basic condition. Omron's industrial wireless solutions are widely used in the automobile manufacturing industry, especially, for example, the Anton system for production intelligence, and other special application sites in automobile production sites. In addition, Omron's industrial wireless application solutions (WT30, WD30) can easily and quickly build a "wireless DeviceNet fieldbus" system. At present, all major Japanese automobile manufacturers have adopted Omron's plan. 3、 The development direction of PLC and the trend of other special application schemes. For a long time, PLC has always been the main battlefield position in the field of industrial control automation, providing a very reliable control scheme for various automatic control equipment
DCS
It has formed a tripartite confrontation with industrial PC. At present, the domestic PLC market is still dominated by foreign products, such as Omron, Siemens, Modicon, A-B, Mitsubishi and GE products. Although there are about 30 manufacturers in China, they have not yet reached a sufficient production scale. Experts estimate that from 2000, the sales volume of PLC in the domestic market was 150000~200000 sets (about 90% of which were imported), about 2.5~3.5 billion yuan, with an annual growth rate of about 12%. It is estimated that by 2005, the demand for PLC in China will reach about 250000 sets, about 3.5~4.5 billion yuan. At the same time, the changes in the PLC market also reflected the situation of the world's manufacturing industry, which declined significantly after 2000. However, according to the prediction of Automation Research Corp, despite the global economic downturn, the PLC market will recover. It is estimated that the global PLC market was US $7.6 billion in 2000, and will return to US $7.6 billion by the end of 2005, and continue to grow slightly. Basically, miniaturization, networking, PC and openness are the main development directions of PLC in the future. However, with the further improvement and development of the soft PLC control configuration software, the market share installed with the soft PLC configuration software and PC based control will gradually grow.
