Industrial Ethernet’s Role Becoming Ever More Important in China

工業(yè)以太網(wǎng)在中國(guó)市場(chǎng)的地位愈加重要

The Chinese market for industrial Ethernet & Fieldbus Technologies grew by 18 million nodes in 2012. More than 3 million nodes used Ethernet and the remainder used Fieldbus technology。

2012年，中國(guó)市場(chǎng)的工業(yè)以太網(wǎng)和現(xiàn)場(chǎng)總線技術(shù)增加了1800萬(wàn)個(gè)節(jié)點(diǎn)，其中超過(guò)300萬(wàn)個(gè)節(jié)點(diǎn)應(yīng)用了以太網(wǎng)技術(shù)，其余的則是現(xiàn)場(chǎng)總線技術(shù)。

Although Fieldbus has a large base of new connected nodes in China, the usage of Fieldbus is not as common as in developed countries such as Germany or the United States. This is mainly because Chinese customers are encountering networking technology much later than those developing countries.

盡管現(xiàn)場(chǎng)總線在中國(guó)的新增連接節(jié)點(diǎn)數(shù)量較多，但現(xiàn)場(chǎng)總線的應(yīng)用還是沒(méi)有德國(guó)或者美國(guó)等發(fā)達(dá)國(guó)家普及。這主要是因?yàn)橹袊?guó)用戶應(yīng)用網(wǎng)絡(luò)技術(shù)遠(yuǎn)遠(yuǎn)晚于其他發(fā)展中國(guó)家。

However, the growing speed of Ethernet is quite considerable in China and we think it is a great opportunity for Chinese customers to upgrade their automation system under current market condition. Customers will just jump from old Fieldbus Technologies direct to Ethernet now and actually many of them are doing right now.  The Chinese market is currently engaged in extensive upgrading and new infrastructure construction， and that will require a great deal of Ethernet applications.

然而，以太網(wǎng)在中國(guó)的發(fā)展速度非常迅速，我們認(rèn)為，這是中國(guó)用戶在目前的市場(chǎng)條件下，升級(jí)自動(dòng)化系統(tǒng)的良機(jī)。 用戶將直接從舊的現(xiàn)場(chǎng)總線技術(shù)跳到現(xiàn)在的以太網(wǎng)，實(shí)際上，也確有不少的用戶正在這樣做。中國(guó)市場(chǎng)目前正在推動(dòng)產(chǎn)業(yè)升級(jí)以及新一輪的基礎(chǔ)設(shè)施建設(shè)，這也將產(chǎn)生大量的以太網(wǎng)應(yīng)用。

In China, international brands are quite influential. This is also true for industrial networking protocols because most of them having their supporting companies. For example, the most popular Fieldbus protocols in China are PROFIBUS and CC-Link, which are developed and promoted by Siemens and Mitsubishi separately, which command large market share in China.

在中國(guó)，國(guó)際品牌都相當(dāng)有影響力。這也適用于工業(yè)網(wǎng)絡(luò)協(xié)議，因?yàn)樗麄兇蟛糠侄加懈髯缘闹С制髽I(yè)。比如，在中國(guó)應(yīng)用最廣的現(xiàn)場(chǎng)總線協(xié)議是PROFIBUS 和CC-Link，分別由西門子和三菱這兩家在中國(guó)市場(chǎng)份額較大的公司開(kāi)發(fā)和推廣。

On the other hand, some open protocols also have a large number of nodes connected, and the most representative ones are CANOpen, Modbus and HART. However, all three protocols don’t deliver strong functionality, and they are more likely to be used in low-end applications for easy connections.

另一方面，一些開(kāi)放協(xié)議也有大量的關(guān)聯(lián)節(jié)點(diǎn)，最有代表性的是CANOpen， Modbus和HART。不過(guò)，這三個(gè)協(xié)議在功能上均不算太強(qiáng)，往往被用于易于連接的低端應(yīng)用。

With the upgrading of old facilities and the construction of new plants in China, customers also are being compelled to upgrade their systems using Ethernet. However, this move will not only be implemented by the customers, but also by the industrial automation vendors as well.

隨著中國(guó)市場(chǎng)舊工廠的升級(jí)改造和新廠的投建，用戶也將被迫使用以太網(wǎng)來(lái)升級(jí)他們的系統(tǒng)。而且，不僅僅是用戶采取這一措施，工業(yè)自動(dòng)化供應(yīng)商也將如此。

Most protocols have Ethernet variants. Because of this, many Fieldbus users will turn to the Ethernet of the application, for example, PROFIBUS to PROFINET, CC-Link to CC-Link IE. And the new automation products will also support those new Ethernet connections.

大多數(shù)協(xié)議有其以太網(wǎng)變體。正因?yàn)槿绱?，許多現(xiàn)場(chǎng)總線用戶將應(yīng)用轉(zhuǎn)向以太網(wǎng)，例如，PROFIBUS到PROFINET，CC-Link到CC-Link IE。而新的自動(dòng)化產(chǎn)品也將支持這些新的以太網(wǎng)連接。
