The Allen-Bradley PanelView 2711P-T12C4D9 is a user-controlled operator panel that uses a state-of-the-art touch screen as its primary input mechanism. The touch screen can be used to specify functions for machine applications and trigger these functions based on the user’s requirements. These panels can be used to monitor, control, and display information graphically through a versatile user interface. The human-machine interface allows the user to study the system performance and understand the status of applications being processed by the industrial automation system.

The Allen-Bradley 2711P-T12C4D9 operator panel can be configured depending on the control system requirements preferred by the operator. The terminal package is shipped as a closed desktop system by default. The start-up option can be changed to an open desktop configuration by requesting desktop access. This improves the versatility of the terminal and ensures that it can be used in a wide range of automation systems.

The 2711P-T12C4D9 is an Allen-Bradley PanelView Plus 6 series 1250 terminal. The terminal is equipped with a 10.4-inch color display screen that has a resolution of 640 x 480 pixels. The display screen also supports 18-bit color graphics. The display screen is lit by a cold-cathode fluorescent lamp (CCFL). The terminal requires an input voltage of 24 VDC. To increase the performance of this terminal, the speed of the processor has been increased from 350 MHz to 1 GHz and the operator interface touch screen has a 70% faster response than previous models. The 2711P-T12C4D9 unit is made up of the display module, input touch module, and logic module. The RS-232 port on this operator terminal is used to connect a PC or handheld terminal for programming purposes and to describe tags in the terminal memory to be later used by the PLC program. The internal memory is 512 MB RAM and 512 MB nonvolatile memory, with approximately 79 MB of free user memory. The RS-232 port on this terminal gives operators the ability to connect the module to external devices, printers, keyboards, etc. The terminal operating temperature is 0 to 55 degrees Celsius (32 to 131 degrees Fahrenheit).

The 2711P-T12C4D9 is an operator terminal that was created by the company known as Allen-Bradley. This terminal belongs to Allen-Bradley's PanelView Plus 6 - 1250 series of terminals. This particular terminal has a 10.4 inch display size with a 640 x 480 resolution. The screen also utilizes 18-bit color graphics. The input voltage required to power this terminal is 24 volts direct current (DC). To increase the performance of this terminal, the processor speed has been improved from 350 MHz to 1 GHz. Also, the touchscreen interface on this terminal has a 70% faster response time compared to previous models.

There are three (3) primary components when it comes to this terminal. These components include the input touch, logic, and display modules. These components are organized in ways that allow them to be upgraded, migrated, or even interchanged with other units, should the need arise. There are also numerous embedded communication ports within this Allen-Bradley terminal. These communication ports include one Ethernet port, one RS-232 port, and two USB ports. These communication ports allow this terminal to be connected to other devices, machines, or controllers, thus, allowing for a more efficient network between each device. Additionally, this unit can be connected to numerous other external devices, such as printers and keyboards to name a few. The internal memory of this terminal is 512 MB (megabytes) of RAM and 512 MB (megabytes) of nonvolatile (ROM), with approximately 79 megabytes of ROM being saved and used for free user memory. This terminal is capable of being operated within a temperature range of 32 to 131 °F.
