Allen-Bradley 1784-U2DHP USB-To-Data Highway Plus Adapter

Allen-Bradley 1784-U2DHP USB-to-Data Highway Plus Adapter is a USB interface that bridges a PC with Allen-Bradley DH+ networks, enabling direct communication with PLC-5 and SLC 500 devices on the Data Highway Plus backbone. The adapter provides a USB connection on the host computer side and a DH+ interface on the network side, allowing programming, diagnostics, and data exchange with DH+-enabled controllers without requiring a legacy serial port setup. As part of Rockwell Automation’s 1784 USB-to-DH+ product family, the 1784-U2DHP serves as a dedicated USB-to-DH+ cable solution designed to simplify access to DH+ networks for development, testing, and maintenance tasks in industrial automation environments. Typical applications include ladder logic verification, module configuration, and troubleshooting of DH+ networks in factories that rely on PLC-5 or SLC 500 controllers, where engineers need reliable PC connectivity for programming software and device monitoring. This model is cataloged under Allen-Bradley 1784-U2DHP and is used to interface modern PCs with legacy DH+ fieldbus segments, providing a streamlined bridge between USB-equipped workstations and the Data Highway Plus ecosystem.
