Deterministic Network Backplane & Fieldbus Characteristics
The cable assembly provides deterministic network physical layer stability by maintaining a uniform 75 Ohm characteristic impedance across extended trunk distances up to 1000 m without repeaters. The quad-shielding architecture mitigates high-frequency electromagnetic noise and radio frequency interference in harsh industrial environments. Optimized dielectric foam polyethylene construction minimizes signal attenuation, preserving Manchester-encoded signal edge integrity and reducing bit error rates across multi-drop ControlNet tap connections.
Frequently Asked Questions
Q: Can the 1786-RG6F flexible coaxial cable be intermixed with standard 1786-RG6 trunk cable in the same segment?
A: Yes. The 1786-RG6F maintains identical 75 Ohm electrical impedance and velocity of propagation parameters as the standard 1786-RG6 trunk cable, allowing seamless connection within the same network segment without causing impedance mismatches or signal reflections.
Q: What is the maximum recommended segment length for a ControlNet trunk built with 1786-RG6F?
A: The maximum total segment length is 1000 m (3280 ft) at 5 Mbps, provided no repeaters are used and the cumulative attenuation across all installed taps and connectors remains within the ControlNet physical layer loss budget.
Q: What precautions should be observed regarding termination resistors on 1786-RG6F runs?
A: Every un-tapped physical end of the coaxial cable segment must be terminated with a 75 Ohm BNC termination resistor to prevent high-frequency signal reflections from corrupting deterministic communications.
Field Installation Guidelines
- Minimum Bend Radius: Maintain a bend radius no smaller than 75 mm during installation to prevent deformation of the foam polyethylene dielectric and subsequent impedance changes.
- Shield Grounding: Ensure proper grounding of the coaxial shield system at the dedicated network tap points in accordance with Rockwell Automation ControlNet site guidelines. Do not ground the cable shield at multiple arbitrary field points to prevent ground loops.
- Connector Assembly: Use standard ControlNet-compatible BNC compression or crimp connectors designed specifically for RG-6 quad-shield coaxial cable to prevent crushing the center conductor or tearing the foil layers.
- Cable Separation: Route the cable in dedicated, grounded metallic conduits or cable trays separated from high-voltage AC power lines and variable frequency drive (VFD) output leads by at least 300 mm.
