【功能描述】
UNITROL 1020是一款功能強(qiáng)大的控制器，通?；赗S485或RS232異步串口通訊協(xié)議進(jìn)行總線方式的通訊。
在應(yīng)用對(duì)象規(guī)模上，它主要被用于小型自控場(chǎng)所，如設(shè)備的控制或少量模擬量的控制及聯(lián)鎖。盡管這個(gè)概念不太準(zhǔn)確，但習(xí)慣上我們將大于600點(diǎn)的系統(tǒng)稱為DCS，而小于這個(gè)規(guī)模的系統(tǒng)則稱為PLC。
UNITROL 1020在系統(tǒng)結(jié)構(gòu)上與DCS相似，控制器與IO站使用現(xiàn)場(chǎng)總線進(jìn)行通訊，控制器與計(jì)算機(jī)之間在沒(méi)有擴(kuò)展要求的情況下也會(huì)使用這種總線通訊方式。
UNITROL 1020具有五個(gè)雙色LED狀態(tài)指示燈，可以顯示光纖鏈路以及電源故障等告警信息。它可以作為主單元控制更復(fù)雜的系統(tǒng)，為具有多個(gè)傳感器的大型機(jī)械提供保護(hù)，也可以作為獨(dú)立的單元控制
連接多達(dá)四個(gè)安全裝置的小型機(jī)械。其安全水平達(dá)到了PL e，并且具有SIL 3的安全等級(jí)。此外，它還能在-10到55攝氏度的工作溫度范圍內(nèi)穩(wěn)定運(yùn)行。
UNITROL 1020具有強(qiáng)大的診斷功能?？偩€背板監(jiān)控、地址錯(cuò)誤、總線超時(shí)等錯(cuò)誤都可以通過(guò)定位紅色錯(cuò)誤指示器進(jìn)行診斷。操作員站還提供了更詳細(xì)的診斷信息，包括CPU指令集測(cè)試、CPU看門狗、
總線背板監(jiān)控等多種系統(tǒng)測(cè)試功能。
UNITROL 1020被廣泛應(yīng)用于各種工業(yè)場(chǎng)合。例如，在某電廠的七臺(tái)鍋爐中，UNITROL 1020直接作用于主蒸汽支架的parker執(zhí)行機(jī)構(gòu)，用于生產(chǎn)高達(dá)每小時(shí)860噸的蒸汽。此外，它還在海水淡化過(guò)程
中發(fā)揮了重要作用，確保了飲用水的純凈和健康。
UNITROL 1020是一款功能豐富、性能穩(wěn)定且易于維護(hù)的控制器，適用于各種小型自控場(chǎng)所和工業(yè)應(yīng)用。

【英文介紹】
The UNITROL 1020 is a powerful controller, usually based on RS485 or RS232 asynchronous serial communication protocol for bus mode communication.
In the application object scale, it is mainly used in small automatic control places, such as the control of equipment or a small amount of analog control and interlocking. Although
the concept is not quite accurate, it is customary to refer to systems greater than 600 points as DCS, and systems smaller than this scale as PLC. UNITROL 1020 is similar to DCS in system
structure, the controller and IO station use fieldbus for communication, and this bus communication mode is also used between the controller and the computer in the case of no expansion
requirements.
The UNITROL 1020 has five two-color LED status indicators, which can display alarm information such as fiber link and power failure. It can be used as a master unit to control more complex
systems, providing protection for large machinery with multiple sensors, or as a separate unit to control smaller machinery connected with up to four safety devices. It has a safety level of PLe
and a safety level of SIL 3. In addition, it can also operate stably in the operating temperature range of -10 to 55 degrees Celsius.
UNITROL 1020 has powerful diagnostic functions. Errors such as bus backplane monitoring, address errors, and bus timeouts can all be diagnosed by locating the red error indicator. The operator
station also provides more detailed diagnostic information, including CPU instruction set testing, CPU watchdog, bus backplane monitoring and many other system test functions.
UNITROL 1020 is widely used in various industrial applications. For example, in seven boilers at a power plant, the UNITROL 1020 acts directly on the parker actuators of the main steam support
to produce up to 860 tons of steam per hour. In addition, it also plays an important role in the desalination process, ensuring the purity and health of drinking water.
The UNITROL 1020 is a feature-rich, stable and easy to maintain controller for a wide range of small automation premises and industrial applications.
