2711-NC13 | Allen Bradley | Communication Cable

The Allen Bradley 2711-NC13, also cataloged as the 2711-NC13 Communication Cable, operates as a dedicated hardware component for serial data transmission within PanelView Plus 6 and controller communication networks. This cable provides direct physical/electrical execution of RS-232 signaling between human-machine interface (HMI) terminals and host controllers, utilizing a 9-pin D-shell configuration to establish point-to-point programming or operational links.

Hardware Specifications

PLC and Drive Deterministic Network Connectivity

The 2711-NC13 serves as the physical interface for serial communication tasks within Allen-Bradley control architectures. It facilitates the transfer of configuration data and real-time process monitoring between the operator terminal and the PLC backplane. When managing high-speed data exchanges or firmware flash compatibility updates, the integrity of the RS-232 physical layer is required to ensure that transmission latencies remain within the specified operational windows. This cable is optimized to handle the serial timing requirements defined for PanelView Plus terminals, ensuring consistent handshaking protocols without signal degradation over its 5-meter reach.

Frequently Asked Questions (FAQ)

Q: Is this cable suitable for use in high-EMI environments?

A: RS-232 is an unbalanced signaling standard and is susceptible to electromagnetic interference. In high-EMI areas, ensure the cable is routed in dedicated conduits and separated from high-voltage AC lines to prevent data corruption or communication timeout errors.

Q: Can this cable be used for programming other serial devices?

A: The 2711-NC13 is a point-to-point RS-232 cable. While it may physically connect to other 9-pin D-shell serial ports, ensure the pinout (Tx, Rx, GND) matches the requirements of the third-party hardware before connection.

Field Installation Guidelines

• Connector Engagement: Ensure both ends of the D-shell connector are fully inserted into the respective ports and the retaining screws are tightened to prevent mechanical disconnection due to vibration.
• Cable Routing: Maintain a minimum bend radius of 50 mm to protect the internal conductor geometry. Avoid pulling the cable with excessive force, as this can damage the internal shielding or cause continuity failures in the wire strands.
• Grounding: The RS-232 communication interface relies on a common ground reference. Ensure that the HMI and the connected controller are referenced to a common earth ground to mitigate ground loops that can induce current flow through the cable shield.
• Physical Integrity: Inspect the cable periodically for signs of abrasion or insulation degradation, particularly if the cable is routed through industrial machinery or exposed to hydraulic fluids.
