Emerson Adds Secure Bluetooth Technology to Fisher FIELDVUE DVC7K-H Valve Controller for Wireless Diagnostics 

MARSHALLTOWN, Iowa — June 30, 2026 — Emerson (NYSE: EMR), the global automation leader, has added secure Bluetooth wireless technology to its Fisher FIELDVUE DVC7K-H Digital Valve Controller through its latest firmware release, enabling maintenance teams to configure and diagnose field instruments without physical communication connections. Emerson has added Bluetooth wireless technology to its Fisher FIELDVUE DVC7K-H Digital Valve Controller with the latest firmware release, providing maintenance teams with secure, wireless connectivity for configuration and diagnostics.

The enhancement targets industrial process operations, where reducing reliance on cabled connections can improve field efficiency and worker safety in demanding plant environments. 

The Bluetooth capability on the DVC7K-H is supported across Windows and mobile platforms, allowing technicians to configure and diagnose the controller wirelessly. The addition of Bluetooth capability to the DVC7K-H is supported by Windows and mobile platforms, allowing technicians to configure and diagnose the DVC7K-H wirelessly.

Emerson said the update complements its recently redesigned AMS Trex Device Communicator and its ValveLink Pro monitoring software, both of which now support Bluetooth communication, creating a unified ecosystem for managing devices in the field. Emerson recently launched a redesigned AMS Trex Device Communicator with features that support Bluetooth technology, and ValveLink Pro monitoring software also supports communication via Bluetooth technology.

Key Highlights: 

• New DVC7K-H firmware adds secure Bluetooth wireless connectivity for cable-free configuration and diagnostics. New firmware for the Fisher FIELDVUE DVC7K-H digital valve controller delivers secure wireless access and simplifies valve configuration workflows.

• Functionality is supported on both Windows and mobile platforms, extending technician flexibility in the field. The Bluetooth capability is supported by Windows and mobile platforms.

• Devices with the Advanced Diagnostic (AD) tier can run offline diagnostics such as step response tests and valve signatures. Devices purchased with the Advanced Diagnostic tier can run offline diagnostics like step response tests and valve signatures.

• Bluetooth functionality requires DVC7K-H Firmware 2 or later and is subject to country-specific approvals. The functionality is available only on devices running DVC7K-H Firmware 2 or later and is subject to country-specific approvals.

Analyst Insight: 

NMSC analysts note that the integration of secure Bluetooth wireless technology into industrial valve controllers reflects the broader migration of the Bluetooth 5 Market beyond consumer audio into industrial automation, where extended range, low power consumption and robust security are increasingly prioritized. According to analysts at Next Move Strategy Consulting, the Bluetooth 5 Market is projected to reach USD 22.6 billion by 2035, supported by expanding adoption across the industrial Internet of Things. 

Industry Outlook: 

As process manufacturers pursue predictive maintenance and remote diagnostics, wireless-enabled field instruments are expected to gain traction, positioning Bluetooth as a connectivity layer for the industrial automation sector. Continued adoption will likely hinge on security assurances and region-specific regulatory approvals, both of which Emerson has referenced for its DVC7K-H deployment.
