Allen-Bradley 2711C-CBL-AB03 Programming Cable

The Allen-Bradley 2711C-CBL-AB03, also cataloged as the 2711C-CBL-AB03 Operating/Programming Cable, operates as a dedicated hardware component for serial communications and point-to-point data exchange between PanelView Component terminals and SLC 5/01, 5/02, and 5/03 controllers. It establishes direct physical/electrical signal routing converting between 5-pin RS-485 terminal blocks and RJ45 modular jack connectors.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility

The cable assembly provides physical layer continuity for DH-485 deterministic network communications between HMI terminals and target controllers. Maintaining firmware flash compatibility across connected HMI hardware and SLC 500 processor series, the double-shielded twisted-pair construction suppresses high-frequency electromagnetic interference (EMI) and prevents noise transients from degrading point-to-point register exchange across serial communication loops.

Frequently Asked Questions

Q: What are the specific connector types on the 2711C-CBL-AB03 cable assembly?

A: One end terminates in a 5-pin RS-485 removable terminal block designed for PanelView Component ports, while the opposite end features an RJ45 modular plug for connecting directly to the DH-485 port on SLC 5/01, 5/02, or 5/03 processors.

Q: Can this cable be used for both runtime operations and application programming?

A: Yes, the cable supports both runtime controller-to-HMI data exchange and programming communications over DH-485 serial connections.

Q: Does the 2711C-CBL-AB03 require an external power supply or inline converter?

A: No, the 2711C-CBL-AB03 is a passive pin-to-pin signal adapter cable requiring no external supply voltage or active signal conversion.

Field Installation Guidelines

1. Power down the controller and HMI terminal prior to attaching or disconnecting serial communication cables.
2. Insert the 5-pin RS-485 terminal block connector firmly into the matching serial communications port on the PanelView Component terminal.
3. Plug the RJ45 connector into the designated DH-485 channel port on the SLC 5/01, 5/02, or 5/03 processor until the retention tab latches securely.
4. Route the cable through grounded panel wire ducts, keeping it physically separated from AC line power cables and VFD output wires.
5. Secure any cable drain wire directly to the main cabinet protective earth (PE) ground bar to preserve noise immunity.
