Description
Allen-Bradley 1747-CP3 Programming Cable
The Allen-Bradley 1747-CP3, also cataloged as the 1747-CP3 Programming Cable, serves as the primary SLC 500 programming cable utilized to execute RS-232 physical layer communication between a personal computer and SLC 5/03, 5/04, and 5/05 processor ports across SLC 500 controller platforms. The assembly provides DB9 serial electrical linkage for programming, monitoring, and data exchange via RSLogix-compatible interfaces.

EtherNet/IP and RS-232 Programming Link Behavior
The 1747-CP3 implements a shielded RS-232 point-to-point communication path between a PC serial interface and SLC 500 processor communication port. Signal transmission is single-ended, with timing and protocol framing managed by the processor UART and RSLogix driver stack.
Electrical noise immunity is provided by cable shielding and connector grounding continuity. No protocol conversion or isolation is performed within the cable assembly; isolation, where required, is implemented at controller or interface hardware level.
Frequently Asked Questions
Q: Does the 1747-CP3 provide electrical isolation between PC and PLC?
A: No. The cable is a passive RS-232 conductor. Isolation, if required, must be provided by external interface hardware.
Q: Can the cable be used with SLC 5/02 processors?
A: No. The 1747-CP3 is specified for SLC 5/03, 5/04, and 5/05 processors with compatible RS-232 programming ports.
Q: Does the cable support hot-plug connection during active communication?
A: RS-232 signaling is not designed for hot insertion. Connection or removal during active communication may corrupt data frames.
Field Installation Guidelines
- Verify correct DB9 orientation before mating connectors to prevent pin damage.
- Maintain continuous shield integrity and ensure proper chassis grounding at system side.
- Route cable separately from high-noise power conductors to reduce induced coupling.
- Avoid sharp bending at connector junctions to maintain impedance stability.
- Ensure secure fastening of connector screws to prevent intermittent RS-232 contact loss.
