Management of Change
Management of Change (MOC) is a procedure used to proactively manage changes
that have the potential to impact safety or the process within a plant. Evaluating
new techniques for improving MOC approval procedures can have an impact on
plant efciency. Historically, upgrading obsolete products or replacing existing
process control equipment had been delayed or abandoned due to the extensive
paperwork involved in completing a complex MOC approval sheet.
Displayed in the following sections are design comparisons between the current
DVC6200 HW2 and legacy HW1 products. These comparisons demonstrate how
the design of Fisher instrument technologies users to efciently transition to newer
Fisher™ FIELDVUE™ products.
Background
In order to continue to increase the usefulness and value of the DVC6200 digital
valve controller, additional features and functions have been implemented within
the electronics hardware (HW) and rmware. These changes include a new
auto travel calibration button, simplied wiring terminals, and HART 7 device
registration.

FIELDVUE DVC6200 HW1 and DVC6200 HW2 Instrument Comparison
There are four elements of the DVC6200 instrument which have changed with this
HW2 enhancement:
Terminal Box
Two push buttons have been added to the terminal box to improve ease of use.
The “CAL” button allows the user to perform an auto travel calibration routine
locally at the valve without the need for additional tools. This button is disabled
