Hardware Specifications

Allen-Bradley Industrial Control and Drive Communication Integration

The 2711-K6C8L1 terminal is engineered to integrate directly with industrial control networks using built-in Data Highway Plus (DH+) and RS-232 communication protocols. Designed to handle deterministic token-passing communication across industrial data highways, the internal communication processor executes real-time tag updates with connected programmable logic controllers without inducing network latency. The hardware architecture incorporates channel isolation across serial and network ports to mitigate electromagnetic interference, ensuring data integrity across high-noise industrial plant environments.

Frequently Asked Questions

Q: Does the 2711-K6C8L1 terminal support field replacement of the internal display backlight?

A: Yes. The unit features a service-accessible backlight assembly that allows maintenance personnel to replace worn display lamps without replacing the entire operator terminal assembly.

Q: What are the primary network termination requirements when connecting this terminal to a Data Highway Plus (DH+) trunk line?

A: DH+ installations require proper 150-ohm biasing resistors at both physical ends of the trunk cable to prevent signal reflections and ensure reliable communication framing across the node drop lines.

Field Installation Guidelines

1. Isolate and lock out all 24 VDC control power feeds and DH+ communication cables before performing mechanical panel cutout or wiring tasks.
2. Cut the enclosure panel mounting opening to match the exact dimensional footprint specified for PanelView 600 terminals, ensuring clean deburred edges.
3. Insert the terminal through the front of the enclosure cutout, making sure the integral rubber gasket forms a continuous seal against the panel face.
4. Secure the unit evenly using the provided panel mounting clips, tightening clamping screws sequentially to distribute clamping pressure and maintain NEMA enclosure sealing integrity.
5. Connect the 24 VDC supply lines to the terminal power block and secure the Data Highway Plus shielded cable to the communication port terminals, ensuring proper shield grounding to earth.
