>>>>>型号:UNITROL 1020 控制器
【功能描述】
UNITROL 1020是一款功能强大的控制器，通常基于RS485或RS232异步串口通讯协议进行总线方式的通讯。
在应用对象规模上，它主要被用于小型自控场所，如设备的控制或少量模拟量的控制及联锁。尽管这个概念不太准确，但习惯上我们将大于600点的系统称为DCS，而小于这个规模的系统则称为PLC。
UNITROL 1020在系统结构上与DCS相似，控制器与IO站使用现场总线进行通讯，控制器与计算机之间在没有扩展要求的情况下也会使用这种总线通讯方式。
UNITROL 1020具有五个双色LED状态指示灯，可以显示光纤链路以及电源故障等告警信息。它可以作为主单元控制更复杂的系统，为具有多个传感器的大型机械提供保护，也可以作为独立的单元控制
连接多达四个安全装置的小型机械。其安全水平达到了PL e，并且具有SIL 3的安全等级。此外，它还能在-10到55摄氏度的工作温度范围内稳定运行。
UNITROL 1020具有强大的诊断功能。总线背板监控、地址错误、总线超时等错误都可以通过定位红色错误指示器进行诊断。操作员站还提供了更详细的诊断信息，包括CPU指令集测试、CPU看门狗、
总线背板监控等多种系统测试功能。
UNITROL 1020被广泛应用于各种工业场合。例如，在某电厂的七台锅炉中，UNITROL 1020直接作用于主蒸汽支架的parker执行机构，用于生产高达每小时860吨的蒸汽。此外，它还在海水淡化过程
中发挥了重要作用，确保了饮用水的纯净和健康。
UNITROL 1020是一款功能丰富、性能稳定且易于维护的控制器，适用于各种小型自控场所和工业应用。

【英文介绍】
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.
