是否有較強(qiáng)的售后服務(wù)與技術(shù)支持。
相對(duì)于自控系統(tǒng)性能的好壞優(yōu)先于價(jià)格的選擇。只是在前面幾項(xiàng)比較接近，又不易選擇時(shí)，才考慮價(jià)格因數(shù)，選擇性價(jià)比比較高的產(chǎn)品。
在實(shí)際選型過程中，往往受到多方面的制約，不一定要考慮以上全部方面，但其中有些項(xiàng)是必須考慮的，而存在的問題也必須通過其它替代方式加以解決。
一般來說通過前5項(xiàng)的比較，已可確定2~3種產(chǎn)品，再考慮到后幾項(xiàng)，便可選中較滿意的PLC。隨著科學(xué)技術(shù)的不斷發(fā)展，PLC產(chǎn)品也一定會(huì)有一個(gè)統(tǒng)一的標(biāo)準(zhǔn)。那時(shí)，挑選PLC將不再是困難的事情。
編程控制器技術(shù)討論與未來發(fā)展
隨著時(shí)代的發(fā)展,當(dāng)今的技術(shù)也日趨完善、競(jìng)爭(zhēng)愈演愈烈;單靠人工的操作已不能滿足于目前的制造業(yè)前景,也無法保證更高質(zhì)量的要求和高新技術(shù)企業(yè)的形象.
人們?cè)谏a(chǎn)實(shí)踐中看到,自動(dòng)化給人們帶來了極大的便利和產(chǎn)品質(zhì)量上的保證,同時(shí)也減輕了人員的勞動(dòng)強(qiáng)度,減少了人員上的編制.在許多復(fù)雜的生產(chǎn)過程中難以實(shí)現(xiàn)的目標(biāo)控制、整體優(yōu)化、佳決策等,熟練的操作工、技術(shù)人員或?qū)＜?、管理者卻能夠容易判斷和操作,可以獲得滿意的效果.人工智能的研究目標(biāo)正是利用計(jì)算機(jī)來實(shí)現(xiàn)、模擬這些智能行為,通過人腦與計(jì)算機(jī)協(xié)調(diào)工作,以人機(jī)結(jié)合的模式,為解決十分復(fù)雜的問題尋找佳的途徑
