Global PLC market returns to growth in 2017, after two-year contraction
兩年萎縮之后，全球PLC市場(chǎng)2017年將重拾漲勢(shì)

The global market for programmable logic controllers (PLCs) suffered strong headwinds and contracted by 11.5 percent in 2015, with revenue falling to $8.3 billion, according to the IHS Markit PLCs Annual Intelligence Service. The market will continue to contract through 2016 for several reasons, including an unfavorable economic climate in emerging economies. Other concerns include China’s ongoing economic slowdown and overcapacity in most heavy industries, as well as the end of the commodity super-cycle. However, there is light on the horizon: global revenue from PLCs, with their associated software and services, are forecast to grow at a compound annual growth rate (CAGR) of 3.8 percent from 2017 to 2020, reaching $9.3 billion.

《IHS Markit PLC年度情報(bào)服務(wù)》顯示，2015年全球可編程邏輯控制器（PLC）市場(chǎng)經(jīng)歷強(qiáng)烈的動(dòng)蕩，市場(chǎng)萎縮了11.5%，銷售額下降到83億美元。由于多種原因，包括新興經(jīng)濟(jì)體不利的經(jīng)濟(jì)環(huán)境等，這一市場(chǎng)在2016年將繼續(xù)萎縮。其他問題包括中國(guó)持續(xù)的經(jīng)濟(jì)放緩和大多數(shù)重工業(yè)的產(chǎn)能過剩，以及大宗商品超級(jí)周期的結(jié)束。但是，曙光來了：PLC及其相關(guān)軟件和服務(wù)的全球收入，從2017年到2020年，預(yù)計(jì)將以3.8％的復(fù)合年增長(zhǎng)率（CAGR）增長(zhǎng)，達(dá)到93億美元。

Europe, the Middle East and Africa (EMEA) will continue to be the largest regional market for PLCs, accounting for over one third of the 2020 global revenues. The Asia-Pacific market will grow the fastest over the next five years -- especially from 2018 to 2020 – driven by the fast-growing Indian and Southeast Asian markets and a recovering Chinese market tied to South Korean and Taiwanese markets. The American region is expected to be the second-fastest growing market, with a strong recovery starting in 2017.  

歐洲，中東和非洲地區(qū)（EMEA）將繼續(xù)是PLC的最大區(qū)域市場(chǎng)，占2020年全球收入的三分之一以上。由于印度和東南亞市場(chǎng)增長(zhǎng)較快，同時(shí)與韓國(guó)和臺(tái)灣市場(chǎng)息息相關(guān)的中國(guó)市場(chǎng)復(fù)蘇，亞太市場(chǎng)將在未來五年內(nèi)增長(zhǎng)最快，特別是從2018年到2020年。美國(guó)地區(qū)預(yù)計(jì)將是第二快的增長(zhǎng)市場(chǎng)，從2017年開始強(qiáng)勁復(fù)蘇。

Of course, the performance of the PLC market depends largely on the underlying growth in the discrete and process-manufacturing sectors where PLCs are mainly applied. Machine tools, packaging machinery and automotive sectors were the three largest markets for PLCs. However, these markets, -- especially the machine tool sector -- are forecast to grow more slowly from 2015 to 2020 than the market average. The machine-tool sector suffered a big decline in 2015 in China and the United States, which are the leading national markets for machine tools.

當(dāng)然，PLC市場(chǎng)的表現(xiàn)在很大程度上取決于主要應(yīng)用PLC的離散和過程制造行業(yè)的潛在增長(zhǎng)。機(jī)床、包裝機(jī)械和汽車行業(yè)是PLC的三大市場(chǎng)。然而，這幾個(gè)市場(chǎng)，特別是機(jī)床行業(yè)，預(yù)計(jì)從2015年到2020年增長(zhǎng)速度要低于市場(chǎng)平均水平。2015年，機(jī)床行業(yè)在中國(guó)和美國(guó)市場(chǎng)大幅下滑，而這兩個(gè)國(guó)家正是全球領(lǐng)先的機(jī)床市場(chǎng)。

In discrete-manufacturing sectors, robotics is still the fastest growing for PLCs. Currently robots are widely used in automotive manufacturing, the electrical and electronics industries, and other fast-growing industrial production industries. As core components of robots, PLCs are expected to benefit greatly from the global robot boom.  Food, beverage and tobacco machinery will be the second-fastest growing sector from 2015 to 2020. In process manufacturing sectors, water and wastewater, pharmaceutical and power-generation sectors are forecast to grow most quickly.

在離散制造行業(yè)，機(jī)器人仍然是PLC發(fā)展最快的領(lǐng)域。目前機(jī)器人廣泛應(yīng)用于汽車制造、電氣電子工業(yè)等快速增長(zhǎng)的工業(yè)生產(chǎn)行業(yè)。作為機(jī)器人的核心部件，PLC預(yù)計(jì)將從全球機(jī)器人熱潮中受益匪淺。食品、飲料和煙草機(jī)械將是2015年至2020年增長(zhǎng)速度第二快的行業(yè)。在過程制造行業(yè)，水處理、制藥和發(fā)電行業(yè)預(yù)計(jì)增長(zhǎng)最快。
