The 2711-T5A8L1 is a human Machine interface (HMI) device that is part of Allen-Bradley's PanelView 550 Standard operating Terminal. It is an electronic hardware designed to be installed near the machine or process being controlled, providing a real-time operator monitoring and control interface. The terminal has built-in features including a visual screen, operator input interface and communication, as well as an integrated memory module and other basic components. Specifically, the integrated screen is a 5.5-inch monochrome display with a screen resolution of 256 x 128 pixels. The touch-sensitive cells are distributed on the screen in 24 columns x 18 rows, with a single touch cell size of 16 x 16 pixels, which equals a total of 128 touch cells. These units give HMI interactions direct access to runtime objects linked to operator actions and specific triggers. Built-in communication ports include one (1) Data Highway Plus (DH+), compatible with 3-wire cable, Belden 9463 cable, or Allen-Bradley's 1771-CD cable for long distance multi-node communication applications. The secondary port is an RS232 interface that is primarily used to communicate with alarm printers for archiving and record keeping purposes. It comes with built-in graphics libraries, alerts, trends, and recipe objects, while also supporting HMI security configuration.

The 2711-T5A8L1 PanelView 550 touchscreen is an electronic operating interface with features such as pixel graphics and a color or monochrome display. It is one of the PanelView Standard 550 terminals and communicates with PLC and SLC controllers over the DH+ network.
