CP450-T-ETH ABB 控制面板又稱為“觸控屏”、“觸控面板”，是一種可接收觸頭等輸入訊號的感應(yīng)式液晶顯示裝置，當接觸了屏幕上的圖形按鈕時，屏幕上的觸覺反饋系統(tǒng)可根據(jù)預(yù)先編程的程式驅(qū)動各種連結(jié)裝置，可用以取代機械式的按鈕面板，并借由液晶顯示畫面制造出生動的影音效果。

從1974開始出現(xiàn)世界上最早的電阻式觸摸屏以來，隨著科技的發(fā)展和應(yīng)用需 求的增長，各種觸摸技術(shù)相繼誕生以適應(yīng)各種行業(yè)和層次的應(yīng)用。如今，已經(jīng)形成了商業(yè)化的觸摸屏技術(shù)包括：電阻技術(shù)觸摸屏、電容技術(shù)觸摸屏、紅外線技術(shù)觸 摸屏、表面聲波（SAW）技術(shù)觸摸屏等，并已廣泛應(yīng)用到了手機、平板電腦、零售業(yè)、公共信息查詢、多媒體信息系統(tǒng)、醫(yī)療儀器、工業(yè)自動控制、娛樂與餐 飲業(yè)、自動售票系統(tǒng)、?教育系統(tǒng)等許多領(lǐng)域。

CP450-T-ETH ABB 控制面板隨著計算機技術(shù)的發(fā)展，計算機的輸入方式由原來的紙帶輸入到鍵盤輸入、到鼠標輸入、再到觸摸輸入，共經(jīng)歷了四個階段。這個過程是一個從專業(yè)到普及的過程，觸摸屏技術(shù)讓更多的人使用上了計算機。觸摸屏是一種交互輸入設(shè)備，用戶只需用手指或光筆觸摸屏的某位置即可控制計算機的運行。因此，觸摸屏技術(shù)具有操作簡單，使用靈活的特點。

CP450-T-ETH ABB 控制面板和其他計算元件之間的數(shù)字通信(點對點訪問)是DCS的主要優(yōu)勢之一。注意力被適當?shù)丶性诰W(wǎng)絡(luò)上，網(wǎng)絡(luò)提供了所有重要的通信線路，對于過程應(yīng)用，網(wǎng)絡(luò)必須包含特定的功能，例如確定性和冗余性。因此，許多供應(yīng)商接受了IEEE 802.4網(wǎng)絡(luò)標準。當信息技術(shù)進入過程自動化，IEEE 802.3而不是IEEE 802.4作為控制局域網(wǎng)時，這個決定為必要的遷移浪潮奠定了基礎(chǔ)。

CP450-T-ETH ABB control panel, also known as “touch screen”, “touch panel”, is an inductive liquid crystal display device that can receive touch input signals, when touching the graphical button on the screen, the haptic feedback system on the screen can drive various connecting devices according to pre-programmed programs, which can be used to replace the mechanical button panel. And through the LCD screen to create a vivid audio-visual effect.

Since the world’s earliest resistive touch screen appeared in 1974, with the development of science and technology and the growth of application needs, various touch technologies have been born to adapt to various industries and levels of application. Today, commercialized touch screen technologies that have been formed include: Resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, surface acoustic wave (SAW) technology touch screen, etc., and has been widely used in mobile phones, tablet computers, retail, public information inquiry, multimedia information system, medical instruments, industrial automatic control, entertainment and catering industry, automatic ticketing system, education system and many other fields.

CP450-T-ETH ABB Control panel With the development of computer technology, the input mode of the computer has gone through four stages from the original paper tape input to keyboard input, to mouse input, and then to touch input. This process is a process from professional to popular, touch screen technology allows more people to use the computer. Touch screen is a kind of interactive input device, the user only needs to use a finger or light pen touch screen to control the operation of the computer. Therefore, the touch screen technology has the characteristics of simple operation and flexible use.

CP450-T-ETH Digital communication (point-to-point access) between the ABB control panel and other computing elements is one of the main advantages of DCS. Attention is appropriately focused on the network, which provides all the important lines of communication, and for process applications, the network must contain specific functions, such as determinism and redundancy. As a result, many vendors have accepted the IEEE 802.4 networking standard. When information technology moved into process automation, with IEEE 802.3 instead of IEEE 802.4 as the control LAN, this decision set the stage for the necessary wave of migration.
