The 2711P-T6M20D is a Allen-Bradley PanelView Plus 600 terminal. This operator interface offers HMI applications, control, and visual solutions of applications in industrial environments. It has a 5.5-inch grayscale passive matrix film compensated super-twisted nematic display with a resolution of 320 x 240 pixels and a typical brightness of 300 cd/m². This terminal's area is 10.47 inches x 6.58 inches and has an effective area of 4.4 inches x 3.3 inches. The terminal is equipped with a resistive analogue touchscreen interface. The display consists of integrated CCFL backlight as well as a lithium battery with 50,000 and 43800 hours of lifespan, respectively. The terminal operates with an input voltage ranging from 18 to 30 VDC, a typical voltage of roughly 24 VDC, and a maximum energy demand of 25 watts. The 2711P-T6M20D incorporates an RS-232 port, a USB port, an Ethernet port, and a network interface for the communication module on the base unit. This module improves communication to isolated RS-323, DH+, DH-485, and ControlNet networks. Third-party point-to-point communication, DF1 full-duplex communication with controllers through direct/modem connection, and DH-485 communication via serial connection are all supported via the RS-232 port. Ethernet/IP communications, third-party Ethernet communications, including network connections, all are facilitated by the Ethernet port. Both ports allow for application uploads/downloads as well as printing. The terminal has an NEC VR5532A MIPS (million instructions per second) CPU with a computational efficiency of 350 MHz, internal storage of 64 MB, and 64 MB PC100 SDRAM. It features a CompactFlash card slot that can hold up to 512 MB of external storage.
