Description

The USB-1761-1747-CP3 is a USB-to-PLC programming cable designed to facilitate
communication between a PC and Allen-Bradley programmable logic controllers (PLCs) from
the MicroLogix and SLC 500 families. This cable is a modern alternative to traditional serial
cables, allowing USB connectivity for easier setup and operation.
Key Features:
1. Connection Type:
USB-A connector for the PC side.
DB9 female connector for connection to the PLC.
2. Compatibility:
Specifically designed for Allen-Bradley MicroLogix series (e.g., 1000, 1100, 1200, 1400,
1500) and SLC 500 series PLCs.
Replaces traditional RS232 1761-CBL-PM02 and 1747-CP3 cables.
3. Built-in USB-to-RS232 Converter:
Integrated USB-to-RS232 chip for seamless communication between modern PCs and
PLCs that use serial communication protocols.
4. Driver Support:
Compatible with most Windows operating systems (Windows 7/8/10/11, 32-bit and 64-
bit).
Drivers are often required for initial setup, typically included with the cable or
downloadable online.
5. Cable Length:
Usually around 3 meters (10 feet), providing flexibility in positioning the PC and PLC.
6. Applications:
Used for uploading, downloading, monitoring, and editing PLC programs.
Suitable for maintenance, troubleshooting, and commissioning tasks.
7. Durability:
Sturdy construction with industrial-grade materials to withstand frequent use in harsh
environments.
8. Plug-and-Play:
Simplifies setup and eliminates the need for older computers with serial ports.
Important Notes:
• Ensure you install the correct driver before connecting the cable to the PC for proper
functionality.
• Confirm compatibility with your PLC model before purchasing.
• Follow proper handling and connection procedures to avoid damaging the cable or the PLC’s
communication port.
