The Allen-Bradley 2711-B6C16L1 is an operator terminal that is part of the PanelView Standard terminal series. This operator terminal is part of the earliest Human Machine Interface (HMI) products of Allen-Bradley which is typically paired with an Programmable Logic Controller (PLC). Though this product is a obsolete discontinued, it is still capable of communicating with modern controllers including Programmable Automation Controllers (PLC) provided that an appropriate communication interface is provided.

To operate the 2711-B6C16L1, it must be wired to a power supply that provided a supply voltage range of 18-32 VDC. It has a power consumption of 34 Watts or 1.9 A @ 24 VDC and maximum power consumption of 60 VA. This terminal has physical measurement of 192 (h) x 290 (w) x 116 (d) mm or 7.55 (h) x 11.40 (w) x 4.57 (d) in and approximately weighs 2.0 kg or 4.4 lbs.

The 2711-B6C16L1 has a diagonal screen size of 5-inches with display area of 115 (w) x 86 (h) mm (4.54 (w) x 3.4 (h) in. and display resolution of 320 x 234 pixels. This screen is of colored type where animations and static graphics may be implemented with color coding display, increasing the level of information the HMI is able to provide. Users can interact to the connected PLC or PAC device via the touchscreen or keypad interface. The touchscreen section has actuation lifespan of 1 million presses while the keypad input are rated for 2 million operation. To communicate with partner PLC or PAC, this terminal is provided with One (1) ControlNet port. Additionally, an RS232 interface is available however, this port is exclusively used for printer communication.

The discontinued Allen Bradley Panelview 600 2711-B6C15L1 is an operator terminal that enables the user to interface with their machine. This HMI has a 5 in. Color Display. This PanelView allows the user to connect to the machine or process via the ControlNet interface and an RS-232 for printer communication. The user is able to control the HMI using the Keypad/Touchscreen to input information and data. This unit is powered using 18-32 VDC power. It has an internal memory composed of 240 KB Runtime memory and 170 KB non-volatile memory. The approximate shipping weight and dimensions are 6 lbs. and 14 x 11 x 8 in. The ControlNet terminals can connect to a single or multiple controllers on a ControlNet network. They support scheduled and unscheduled access to controller data They also support redundant cabling. The ControlNet terminals support symbolic CIP addressing when communicating to a ControlLogix system. Every terminal features a Network Access port for local access to the ControlNet network.
