【功能描述】
2711-K5A2是一款Allen-Bradley PanelView Standard操作终端，具有集成键盘输入接口、显示区域、通信端口和内部存储器。该电子设备具有紧凑的组件，支持齐平安装到工业级外壳上。
2711-K5A2的键盘输入接口由十（10）个功能键组成，接受本地和全局分配，使任何按钮都可用于特定功能或接受变量分配。除了功能键外，键盘组件还设置了一个数字键，用于输入数字变量和常量;导航键，用于突出显示屏幕中显示的相应对象。
该操作终端还具有5.5英寸单色屏幕，显示区域为120 x 60毫米（4.75 x 2.38英寸），分辨率为256 x 128像素。它配备了一个可更换的内部背光，设计用于运行长达100,000小时。
这缩短并最大限度地延长了工程时间，因为内部测试也可以在不需要物理硬件的情况下完成。
2711-K5A2具有一个170KB的内部随机存取存储器（RAM）和一个240KB的非易失性存储器，用于保存应用程序和系统文件，例如趋势、日志和用户手册。

【英文介绍】
The 2711-K5A2 is an Allen-Bradley PanelView Standard operating terminal with an integrated keyboard input interface, display area, communication port, and internal memory. The electronics feature compact components that support flush mounting onto an industrial-grade housing.
The 2711-K5A2 keyboard input interface consists of ten (10) function keys that accept local and global assignments, making any button available for a specific function or accepting variable assignments. In addition to function keys, the keyboard component also has a numeric key for entering numeric variables and constants; Navigation key, used to highlight the corresponding object displayed on the screen.
The operating terminal also features a 5.5-inch monochrome screen with a display area of 120 x 60 mm (4.75 x 2.38 inches) and a resolution of 256 x 128 pixels. It comes with a replaceable internal backlight and is designed to operate for up to 100,000 hours.
This shortens and maximizes engineering time, as internal testing can also be done without the need for physical hardware.
The 2711-K5A2 has a 170KB internal random access memory (RAM) and a 240KB non-volatile memory for holding application and system files such as trends, logs, and user manuals.
