Product Overview

The Allen-Bradley 1747-C10 Programming/Communication Cable is a replacement cable designed for communication between SLC 500 controllers and compatible peripheral devices. Manufactured for the Allen-Bradley SLC 500 automation platform, this cable provides a physical connection for programming, data access, and communication-related operations during system installation, commissioning, and maintenance.

In industrial automation systems, reliable communication between a programmable logic controller and its programming or operator interface equipment is essential. Engineers use compatible cables to connect controllers with programming interfaces, handheld terminals, and other supported peripherals. The 1747-C10 provides a 6-foot connection, equivalent to approximately 1.8 meters, for installations where a short-distance connection is required.

The cable is associated with the SLC 500 family and is used in processor-to-peripheral connections. Typical applications include connecting compatible interface converters, Data Table Access Modules, and handheld terminals to an SLC 500 controller. It can also serve as a replacement for an existing cable in a legacy control system.

The 1747-C10 should not be confused with the 1747-C11. Although both belong to the SLC 500 cable family, they serve different connection purposes. The 1747-C10 is the 6-foot processor-to-peripheral cable, while the 1747-C11 is a shorter cable used to connect an SLC 500 processor to an isolated link coupler.

The 1747-C10 is now discontinued by Rockwell Automation. It may still be required for maintaining installed SLC 500 systems, particularly where existing programming and peripheral communication arrangements need to be preserved.

Technical Specifications

Note: The 3 kg figure is the supplied shipping weight, not a confirmed net cable weight. Actual connector details and cable condition should be checked against the physical item before installation.

Function and Working Principle

The 1747-C10 provides the physical communication connection between an SLC 500 controller and compatible peripheral equipment. It does not perform signal processing or control logic independently. Instead, it carries the communication signals required by the connected devices.

1. Controller-to-Peripheral Communication

An SLC 500 controller exchanges information with programming and peripheral equipment during configuration, monitoring, and maintenance. The 1747-C10 provides the cable connection required for supported devices.

This connection allows engineers to access controller information through compatible equipment without changing the controller’s installed control program or hardware configuration.

2. Programming Interface Connection

During commissioning or troubleshooting, engineers may need to connect programming equipment to an SLC 500 controller. The 1747-C10 can be used as part of a compatible programming interface arrangement.

The cable itself is not a USB converter or a standalone computer interface. If a modern computer is being used, the required interface converter and software compatibility must be checked separately.

3. Peripheral Device Connection

The cable is associated with supported SLC 500 peripherals, including the 1747-PIC Personal Interface Converter, 1747-DTAM-E Data Table Access Module, and 1747-PT1 Hand-Held Terminal.

These devices provide different functions, but all require a suitable physical connection to communicate with the controller.

4. Signal Transmission

The cable provides the electrical path for communication signals between compatible equipment. Reliable communication depends on the correct cable type, connector condition, wiring integrity, and compatibility of the connected devices.

Damaged conductors, loose connectors, or incorrect cable selection may cause communication interruptions or prevent the connected equipment from recognizing the controller.

Role in Industrial Control Systems

The 1747-C10 supports maintenance and programming activities in industrial systems built around Allen-Bradley SLC 500 controllers.

PLC Programming and Maintenance

SLC 500 controllers are used to manage machine sequences, process logic, and industrial equipment. During maintenance, technicians may need to access controller information, inspect program operation, or perform configuration-related tasks.

The 1747-C10 provides the required cable connection when used with compatible programming peripherals.

Communication with Operator Devices

Some SLC 500 installations use handheld terminals or data access devices for local operation and troubleshooting. The 1747-C10 can connect compatible peripherals to the controller, supporting access to controller information.

Commissioning and Troubleshooting

During system commissioning, technicians may need to verify controller operation and communication. A suitable replacement cable helps restore the physical connection when the original cable is damaged, missing, or unreliable.

Legacy System Support

Many industrial facilities continue to operate SLC 500 equipment as part of established production systems. Replacing a failed cable with the correct model can help preserve the existing hardware arrangement and reduce unnecessary changes to the control architecture.

Industrial Applications

The 1747-C10 is primarily used in installations that retain Allen-Bradley SLC 500 controllers and compatible peripheral equipment.

1. Manufacturing Automation

Manufacturing lines often use SLC 500 controllers to coordinate motors, sensors, actuators, and machine sequences. The 1747-C10 can support maintenance access through compatible programming and peripheral devices.

2. Packaging Machinery

Packaging systems may use legacy SLC 500 controllers to manage product feeding, sealing, labeling, and conveying operations. The cable can be used when technicians need to connect supported programming or data-access equipment.

3. Material Handling Systems

Conveyors, transfer stations, and other material-handling equipment may contain SLC 500 controllers. During troubleshooting, a compatible communication cable allows technicians to connect supported peripherals for controller access.

4. Process Automation

Older process-control installations may use SLC 500 hardware to manage pumps, valves, motors, and auxiliary equipment. The 1747-C10 can support maintenance activities where the original controller and peripheral communication arrangement remains in service.

5. Industrial Equipment Maintenance

Maintenance departments may keep replacement communication cables as part of their spare-parts inventory. Having the correct cable available can reduce delays when an existing connection is damaged or unavailable.

Installation and System Integration

The 1747-C10 is a connection accessory rather than a powered control module. Correct identification and handling are important for reliable communication.

1. Confirm the Required Cable Model

Before installation, verify that the equipment requires a 1747-C10. Do not substitute a 1747-C11 simply because both cables belong to the SLC 500 product family.

The 1747-C10 is approximately 6 feet long and is intended for processor-to-peripheral connections. The 1747-C11 is a shorter processor-to-isolated-link-coupler cable.

2. Check Peripheral Compatibility

Confirm the exact peripheral device and its required cable arrangement. The 1747-C10 is associated with compatible SLC 500 programming and communication peripherals, including the 1747-PIC, 1747-DTAM-E, and 1747-PT1.

Do not assume that every SLC 500 communication module uses this cable. Some modules and network accessories require different cable catalog numbers.

3. Inspect the Cable and Connectors

Before connecting the cable, inspect its outer insulation, connector housing, contacts, and strain-relief areas. Look for cuts, deformation, corrosion, loose contacts, or signs of previous repairs.

A cable with damaged insulation or unreliable connectors should not be used in a critical control installation.

4. Connect the Equipment Correctly

Follow the connection instructions for the specific controller and peripheral. Confirm the correct ports and connector orientation before insertion. Avoid applying excessive force to connectors or pulling the cable by its wires.

5. Verify Communication

After connection, use the supported peripheral or programming interface to confirm that communication can be established. If communication fails, check the cable model, connector condition, peripheral compatibility, and controller status before replacing other system components.

6. Maintain Proper Cable Routing

Keep the cable away from sharp edges, excessive heat, moving machinery, and sources of electrical interference. Avoid tight bends, excessive tension, and unnecessary mechanical stress.

When the cable is not in use, store it in a clean and dry location to protect the connectors and insulation.

Compatible System Components

The 1747-C10 is intended for use with compatible SLC 500 controllers and peripheral devices.

Compatibility should always be checked against the controller model, peripheral device, and original wiring arrangement. The 1747-C10 is not a universal cable for every Allen-Bradley PLC family.

Alternative Models and Replacement Considerations

The 1747-C10 has been discontinued, and Rockwell Automation has not announced a planned direct replacement. When sourcing a replacement, the original connection requirements should be identified before considering other cable models.

When choosing an alternative, check:

• The controller model and communication port.
• The peripheral device being connected.
• The cable’s intended connection function.
• Cable length and connector arrangement.
• Compatibility with the installed interface converter.
• Programming software and operating-system requirements.
• Whether the replacement is an original Allen-Bradley product or a third-party alternative.

A cable with a similar connector does not necessarily have the same internal wiring or communication function. Always confirm the connection specification before substitution.
