DHPLUS Protocol Driver

The DHPLUS Protocol driver from Rockwell supports communication between Windows-based industrial software and compatible Data Highway Plus (DH+) equipment. It is intended for technicians, maintenance teams, and system integrators who need the appropriate communication components for an existing Rockwell automation setup. Successful operation also depends on compatible interface hardware and correctly configured industrial software.

Key Features

• DH+ communication support: Provides a software component used in compatible configurations to connect industrial applications with equipment on a Data Highway Plus network.
• Legacy Windows coverage: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; verify that the specific package supports your Windows edition and architecture.
• Industrial system integration: Helps supported Rockwell software work with the communication interface required by your automation environment.
• Maintenance and recovery: Installing a suitable driver can help restore missing communication components after a system rebuild or software change. It does not replace network or hardware troubleshooting.

How to Install DHPLUS Protocol Driver

1. Check your configuration. Identify your Windows version, 32-bit or 64-bit architecture, communication interface, and Rockwell software requirements. For Windows 10/11 systems, note that Windows 11 is not included in the supplied compatibility list; do not assume support.
2. Select a compatible package. Before starting a DHPLUS Protocol driver download for Windows, review the package documentation and supported hardware. Choose the latest version approved for your setup rather than simply the newest available release.
3. Verify the download. Use a trusted source and check the publisher information where available. A free download does not necessarily include licenses for associated industrial software.
4. Install the driver. Follow the package instructions, using administrator permissions if required. Some communication components are installed through their accompanying software rather than through Device Manager. Schedule changes during an approved maintenance window.
5. Restart and test. Restart Windows if prompted, then configure the communication interface in the relevant software. Confirm connectivity to the intended equipment without interrupting active operations.

Keep the driver updated when a compatible update addresses a documented issue or meets a system requirement. Before changing a working industrial installation, review release notes, save configuration details, and prepare a rollback option so you can restore the previous setup if necessary.
