Emerson has enhanced the software for its Fisher FIELDVUE DVC6200 series digital valve controllers, which are now available for use by process industries with PLCs and PROFIBUS communications as the dominant protocol. The digital valve controller with Device Type Manager (DTM) software supports control valve startup, commissioning, and diagnostic activities. It has also been tested and integrated for use with multiple Field Device Tool (FDT) host systems.
The device is suited to a range of industries including food and beverage, water and wastewater, pharmaceutical, pulp and paper, and metals and mining. Available in a variety of materials including stainless steel, the device comes with mounting kits to accommodate different actuators. These mounting kits can be re-used in upgrades to existing FIELDVUE instruments, and for control valves located in critical or hazardous areas, the device may be remotely mounted to enhance its performance in conditions such as high heat or vibration.
Utilising Human-Centred Design concepts, the product also has several features that simplify control valve set-up and monitoring. Its intuitive setup, auto-calibration and simple tuning features save time during commissioning, according to the company. And with the failsafe option, users can set the instrument to hold its last value or position to actuator fail, based on control valve process needs. By incorporating control logic, module assignment, and linkage-less, non-contact sensor technology, the digital valve controllers and DTM are easy to install, provide “plug and play” capabilities, and perform reliably even in harsh environments.
