描述
除了前述的系統(tǒng)平臺(tái)外，硬件架構(gòu)也需要妥善考慮，才能建構(gòu)出智能工廠。首先是聯(lián)機(jī)的基本需求，通信協(xié)議應(yīng)該要盡量選擇市場(chǎng)現(xiàn)有的，盡量減少自行開(kāi)發(fā)，以免設(shè)備之間的聯(lián)機(jī)產(chǎn)生問(wèn)題。
其次是選擇儀控設(shè)施，目前的儀控設(shè)施接口，非常多樣化，除了有目前盛行的Ethernet外，過(guò)去的RS232／422／485仍然還是有在使用。其實(shí)智能工廠也不一定非Ethernet不用，因?yàn)榭紤]建置成本，過(guò)去的投資不一定要舍棄，但不同的儀控設(shè)施接口，會(huì)影響通信線路的配置，包括設(shè)備、距離、速度及成本等，工廠在導(dǎo)入解決方案時(shí)，要做好取舍規(guī)劃。
而在計(jì)算機(jī)設(shè)備的選用方面，包括聯(lián)機(jī)計(jì)算機(jī)數(shù)量與配置、工作環(huán)境、計(jì)算機(jī)規(guī)格及外圍裝置，都要做好充分考慮。專(zhuān)家認(rèn)為，選用的關(guān)鍵完全取決于系統(tǒng)的承受度，該用服務(wù)器就得用服務(wù)器，不要因?yàn)楣?jié)省采購(gòu)成本，而選擇較為便宜的計(jì)算機(jī)設(shè)備，因?yàn)橐坏┻x擇錯(cuò)誤，導(dǎo)致設(shè)備常常故障或當(dāng)機(jī)，維護(hù)成本未必劃算。
至于監(jiān)控網(wǎng)絡(luò)架構(gòu)的考慮方面，要考慮的項(xiàng)目包括工作站的任務(wù)分配、網(wǎng)絡(luò)架構(gòu)規(guī)劃、網(wǎng)絡(luò)流量控制及網(wǎng)絡(luò)安全考慮。在架構(gòu)規(guī)劃時(shí)，可以依照控制責(zé)任區(qū)分、人機(jī)接口規(guī)劃及網(wǎng)絡(luò)功能配合等方向來(lái)考慮。
以控制責(zé)任為例，可以分為控制器及圖控計(jì)算機(jī)，前者重視的是實(shí)時(shí)性、高可靠性，適用低階邏輯性／模擬性之控制，后者則是要求強(qiáng)大的數(shù)據(jù)處理能力，適用高階控制。至于每一個(gè)交換器要裝幾個(gè)控制器，則是取決于對(duì)于速度的要求。人機(jī)界面規(guī)劃方面，一定要導(dǎo)入人因工程的觀念，不管是使用習(xí)慣或是圖形大小，都能符合使用習(xí)慣及現(xiàn)場(chǎng)狀況，如旋鈕的方向、大小及顏色等，要達(dá)到直覺(jué)、簡(jiǎn)易、防誤等要求，其他項(xiàng)目如操作流程、展示方式及安全管制，也都要以符合使用者習(xí)慣為主要考慮。
