產(chǎn)品詳情
是否有較強的售后服務與技術支持。
相對于自控系統(tǒng)性能的好壞優(yōu)先于價格的選擇。只是在前面幾項比較接近,又不易選擇時,才考慮價格因數(shù),選擇性價比比較高的產(chǎn)品。
在實際選型過程中,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項的比較,已可確定2~3種產(chǎn)品,再考慮到后幾項,便可選中較滿意的PLC。隨著科學技術的不斷發(fā)展,PLC產(chǎn)品也一定會有一個統(tǒng)一的標準。那時,挑選PLC將不再是困難的事情。
編程控制器技術討論與未來發(fā)展
隨著時代的發(fā)展,當今的技術也日趨完善、競爭愈演愈烈;單靠人工的操作已不能滿足于目前的制造業(yè)前景,也無法保證更高質量的要求和高新技術企業(yè)的形象.
人們在生產(chǎn)實踐中看到,自動化給人們帶來了極大的便利和產(chǎn)品質量上的保證,同時也減輕了人員的勞動強度,減少了人員上的編制.在許多復雜的生產(chǎn)過程中難以實現(xiàn)的目標控制、整體優(yōu)化、佳決策等,熟練的操作工、技術人員或專家、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正是利用計算機來實現(xiàn)、模擬這些智能行為,通過人腦與計算機協(xié)調(diào)工作,以人機結合的模式,為解決十分復雜的問題尋找佳的途徑
