2711-K6C5 | Allen-Bradley | PanelView 600 Standard Operator Terminal

Configured for human-machine interface interaction in industrial control networks, the Allen-Bradley 2711-K6C5 (2711-K6C5 Operator Terminal) provides direct physical input and visual process monitoring. This unit utilizes a color active matrix TFT display to render runtime data, managed via an integrated 10-key function keypad array. Communication is facilitated through an RS-232 DH-485 port, supporting deterministic data exchange between the terminal and connected programmable controllers.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility

The integration of the 2711-K6C5 into broader industrial architectures requires strict adherence to communication timing and firmware compatibility. As a standard terminal, this hardware operates on a cyclical polling basis via the DH-485 protocol. Firmware versioning must align with the DH-485 driver requirements to prevent communication time-outs or bus collisions. Users must ensure that the communication cable (2711-NC14) maintains shielded integrity to mitigate signal attenuation over extended runs. When updating application objects or bitmaps, the internal nonvolatile memory capacity is constrained to 240 KB; exceeding this threshold requires memory optimization or the reduction of graphical asset density to prevent runtime execution errors.

Frequently Asked Questions

Q: Is this terminal capable of hot-swapping in an active DH-485 network?

A: No. Disconnecting or connecting the RS-232 DH-485 cable while the terminal is powered can induce electrical transients that may corrupt the communication port logic. Always cycle power or initiate a hard reset following cable reconnection.

Q: How is the internal real-time clock battery maintained during power loss?

A: The time clock utilizes an external backup module (2711-NB3 or 2711-NB4). Ensure these modules are tested for voltage levels during routine maintenance cycles to prevent the loss of time-stamped alarm data.

Field Installation Guidelines

• Panel Mounting: Ensure the enclosure cutout provides adequate clearance for the gasket to meet IP65/NEMA 4X seal requirements. Apply mounting clips evenly to prevent chassis distortion, which may lead to seal degradation.
• Grounding: The unit chassis must be bonded to a low-impedance earth ground. Avoid daisy-chaining ground connections with high-frequency noise-generating equipment like VFDs or heavy contactors.
• Wiring: Maintain a minimum separation of 150 mm between the RS-232 communication cabling and any high-voltage AC power lines to minimize electromagnetic interference (EMI).
• Environment: Although rated for indoor NEMA 4X, the unit must be shielded from direct sunlight to prevent liquid crystal degradation and excessive internal heat buildup beyond the operating threshold of the backlight.
