The 2711P-T12C4D8 is PanelView Plus 6 Human Machine Interface (HMI) terminal manufactured by Allen-Bradley/Rockwell Automation. It belongs to the PanelView Plus 6 product line and allows the operator to interface with their machines, monitor, manage, and display application status data/information. This terminal comes with the 2711P-RP8D logic module and the 2711P-RDT12C display module. Other specifications of the 2711P-T12C4D8 operator interface include a 12.1-inch color display and communications capabilities, including Ethernet and RS-232 communication ports. The users can control the operator interface through touchscreen using the touchscreen to enter information and data into the system. This module runs on a power of 18 - 32 volts DC and has an internal RAM capacity of 512 megabytes. Its shipping dimensions are 20 x 14 x 8 inches and has a weight of about 10 pounds.
This terminal features Ethernet/IP – an open industrial network that provides supports for message exchange and real-time I/O messaging. The Ethernet port helps to connect to the controller over an Ethernet/IP network using both standard Ethernet and network connections. It also supports application transfers and printing. Ethernet/IP screen shows data and also allows the users to configure some Ethernet/IP communication settings for the PanelView terminal. The Allen-Bradley 2711P-T12C4D8 Ethernet communication module can be used with the 700 to 1500 terminals if an additional Ethernet port is required; it also has a unique IP address. The port supports RJ45 for MDI/MDI-X connections and 10/100Base-T connector network communication.

The 2711P-T12C4D8 is a PanelView Plus 6 - 1000 series terminal designed by Allen-Bradley. This device has a touchscreen interface with a display size of 12.1 inches. This touchscreen interface is also able to display color. Additionally, the resolution of the touchscreen is 800 x 600 pixels with 18-bit color graphics. Twenty-four (24) volts DC (direct current) is required for this terminal to operate properly. 

This Allen-Bradley terminal provides significant improvements over the PanelView Plus graphic terminals because of two factors. The first factor is that Allen-Bradley managed to increase the speed of the processor up to 1 GHz. The second factor is that the screen transition rate is faster. To be more specific, the screen transition is up to seventy percent (70%) faster. The result of these two factors is a touchscreen operator interface that is not only fast, but also extremely reliable.

There are several different methods as to how the Allen-Bradley 2711P-T12C4D8 can communicate. Embedded into this device is 1 Ethernet port, 1 RS-232 port, and 2 USB ports. These ports allow the 2711P-T12C4D8 to connect to other devices and controllers. The RS-232 port is used to connect a PC, or handheld terminal, for programming purposes. This terminal can be connected to many other external devices as well, such as printers, keyboards etc. When operating the terminal, the temperature around it should remain within a range of 32 to 131 degrees Fahrenheit. When the unit is not operational, the temperature around it should remain within a range of -13 to +185 degrees Fahrenheit.
