1747-CP3 | Allen Bradley | SLC 500 PLC Programmer Cable

Product Overview

The Allen Bradley 1747-CP3 serves as the primary physical link for programming and configuring SLC 500 series processors. This high-performance cable enables direct communication between a workstation or terminal and the PLC’s RS-232 port. It supports critical tasks including firmware updates, ladder logic uploads/downloads, and real-time online monitoring. We supply this unit as 100% Brand New and Factory Original, ensuring precise signal timing and secure physical connections for your automation environment.

Technical Specifications

Engineering Advantages

• Industrial-Grade Shielding: The 1747-CP3 utilizes authentic Belden 9463 cabling. This specialized construction provides superior protection against Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), which often cause data corruption during logic downloads in high-noise factory environments.

• Precision 6-Pin Phoenix Interface: The cable features a high-quality 6-pin Phoenix connector. This specific interface ensures a vibration-resistant seating on the processor’s communication port, preventing accidental disconnections that could lead to CPU faults during online editing.

• Optimal 3-Meter Reach: The 3-meter (118-inch) length provides the necessary flexibility for engineers to position their laptops or programming terminals safely outside the arc-flash boundary or away from moving machinery while maintaining a stable connection.

• Broad Processor Compatibility: This cable bridges legacy and modern SLC architectures. It supports the full spectrum of SLC 5/02 through 5/05 processors, making it an essential tool for facilities running diverse generations of Rockwell hardware.

• Thermal Resiliency: The cable jacketing withstands temperatures up to 60 °C. This thermal rating prevents the insulation from becoming brittle or tacky in hot control cabinets, maintaining the physical integrity of the signal path over years of service.

FAQs

• Can I use the 1747-CP3 for permanent HMI communication?

  Yes. While engineers primarily use the 1747-CP3 for programming, it also functions as a permanent serial link between an SLC processor and a PanelView terminal or a PC running RSLinx. The Belden 9463 core ensures the signal remains stable for long-term data acquisition.

• How does this cable differ from a standard RS-232 null-modem cable?

  The 1747-CP3 utilizes a proprietary pinout specifically designed for the SLC 500 serial port. A standard off-the-shelf DB9 cable will not communicate with the SLC hardware and may cause electrical shorts if the pin configurations conflict with the processor's power output pins.

• What software is required to use this cable?

  To communicate via the 1747-CP3, you require RSLogix 500 and RSLinx Classic. Within RSLinx, you must configure the "RS-232 DF1 Devices" driver to recognize the COM port occupied by this cable.

• Is this a brand new Allen Bradley original?

  Absolutely. We guarantee that every 1747-CP3 we ship is 100% Brand New in its original factory packaging. We do not sell used, repaired, or third-party "equivalent" cables, as they often lack the shielding necessary for industrial reliability.
