我們的優(yōu)勢
公司銷售的進(jìn)口備件從國外生產(chǎn)廠家直接進(jìn)貨，
實(shí)行扁平化的銷售模式，給客戶節(jié)約了時(shí)間和成本。
我們的目標(biāo)就是國內(nèi)用戶采購國外備件遇到困難和疑難時(shí)都能找到我們。
我們能夠及時(shí)地報(bào)出優(yōu)惠的價(jià)格和迅捷的交貨期；國內(nèi)用戶采購國外備件受到獨(dú)家代理壟斷價(jià)格時(shí)，我們會(huì)給用戶提供一個(gè)比較的機(jī)會(huì)，并且為客戶提供=的解決方案。由于我們的訂單集中，訂貨量大，因此我們能提供頗具競爭力的價(jià)格并能夠迅速交貨，我們長期以來致力于解決國內(nèi)用戶采購國外備件中的疑難問題，并為廣大用戶提供電氣及工控自動(dòng)化成套設(shè)備的購銷、現(xiàn)場調(diào)試等全面周到的服務(wù)。

選擇深圳長欣，選擇放心，售后無憂大量現(xiàn)貨，當(dāng)天順豐發(fā)貨！
主營：本特利，英維思，伍德沃德，?？怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂，ACSO，力士樂等各大品牌的DCS系統(tǒng)配件，機(jī)器人系統(tǒng)配件，大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊”（不管能不能看懂，先了解個(gè)大概，以便學(xué)習(xí)編程時(shí)查找）；
2、由位控邏輯入手，逐漸增加定時(shí)、計(jì)數(shù)等條件，把或、與、非關(guān)系理順；
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換；
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解（最好是有個(gè)物理回路驗(yàn)證，比如變頻器+電機(jī)+測速傳感器）；
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制（盡量避免跳轉(zhuǎn)，非跳不可時(shí)也是跳的越近越好）；
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列，GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌，由于PLC的基本框架大同小異，學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡單了。
