Valve controller communications

Emerson has extended the Fisher® FIELDVUE™ digital valve controller family with the addition of the FIELDVUE DVC6200p PROFIBUS PA digital positioner.

The Fisher FIELDVUE DVC6200p digital valve controller is built on Fisher’s highly successful and innovative linkage-less, non-contact sensor technology. PROFIBUS users can now experience the performance and reliability demanded in today’s process control environment.

For throttling control applications, the unit offers an Analogue Output function block, while a Digital Output function block is available for on/off applications. Utilising the best of PROFIBUS PA, the DVC6200p provides a wealth of alerts, trends, and diagnostics to allow for process visibility and control not previously available in a PROFIBUS PA digital valve controller.

A quick set-up and calibration, including performance tuning, can be performed locally in a matter of minutes. For more extensive parameterisation, leading PROFIBUS configuration tools such as Siemens PDM can be used. The DVC6200p supports enhanced device description (EDD) files that allow for quick and easy configuration.

This digital valve controller is certified to Profile 3.02 for PROFIBUS PA devices by the PROFIBUS Nutzerorganisation a.V (PNO).

CSA, IEC Ex, and FM approvals are available now for the DVC6200p. Emerson’s growing portfolio of PROFIBUS-supported interoperable products includes the DeltaV™ digital automation system, AMS Suite asset management software, Fisher® control valves, Rosemount® flow, pressure, and temperature transmitters, Rosemount Analytical transmitters, and Micro Motion® Coriolis mass flowmeters
