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 efciency. 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.

Background

The Fisher FIELDVUE DVC6000 series of digital valve controllers have proven to be
the most reliable digital valve controllers produced. Today, the introduction of the DVC6200 and DVC6200f marks a step change in the technology, which will further
improve the reliability of these instruments in the harshest environments. This step change in technology was made possible by utilizing the proven modular technology
of the one million and counting existing DVC6000 units in the eld today.
December 2019 / D351904X012
The design philosophy of the DVC6200 and DVC6200f allows the user the exibility to transition from legacy FIELDVUE products to the current DVC6200, avoiding
lengthy management of change approval documents. This document will highlight
the design of the DVC6200 and DVC6200f, which incorporates linkage-less, non-
contact feedback technology into an intrinsically safe and explosion-proof package.
This feedback technology has been eld-proven in the DVC2000 since 2004 in high vibration and corrosive environments. Over 73,000 FIELDVUE DVC2000 instruments
have been installed with no failures of this feedback technology.
Displayed in the following sections are design comparisons between the current DVC6200 and legacy DVC6000 products. These comparisons demonstrate how
the design of Fisher technologies allows users to efciently transition to new, more
reliable FIELDVUE products.

9
to be operated and, has a new operations list been stated?
A: Yes. The DVC6200 and DVC6200f are operated the same as the
DVC6000 and DVC600f.
Q: Does the proposed modication introduce new equipment items
that require spare parts, training manuals, maintenance procedures
or training to teach the maintenance department how to maintain them?
A: Yes. The standard components that maintenance may be required
on are the same between the old and new equipment, except for
the differing feedback technology. The mounting methodology also varies between the old and new technology.
Q: Does the proposed modication change the spares for existing pieces
of equipment?
A: No.
3
MOC: DVC6200 and DVC6200f Digital Valve Controllers
Q: Does the proposed modication introduce new equipment items that
10
require periodic predictive maintenance?
A: No. The new equipment items that may require periodic maintenance
are the same as the old equipment items, except for the position
feedback element. The new position feedback element (magnet / hall effect sensor) requires no maintenance where the old feedback element was a potentiometer that required periodic evaluation to
conrm no mechanical issues were present.

Comparison of DVC6000 and DVC6200 Instruments

The DV6200 with HART® communication uses the same internal components,
electronics and covers as the DVC6000. This is detailed below in Table 1. The
DVC6000 uses a potentiometer to obtain position feedback, whereas the DVC6200 position feedback utilizes a Hall effect sensor and magnetic array. This is the same technology as used in the DVC2000. The DVC2000 was the rst Fisher instrument released by Emerson that used a Hall effect sensor and a magnet array to measure valve travel. The Hall effect sensor is located in the DVC6200 housing between two “pole pieces” that are used to sense the magnet ux eld of a magnetic array. The magnet array is mounted to the valve stem. As the valve stem moves, the
magnet array also moves (relative to the sensor). The magnet array is composed of
a series of magnets of different strengths, so the sensor can measure the changing magnetic eld. Since there are no touching parts, this feedback is completely non-
contact and does not rely on linkages.

Figure 1. DVC6000 and DVC6200 Instrument Assembly Comparison
The DVC6200 and DVC6200f will utilize a new back housing and mounting as is illustrated in Figures 2 and 3 shown on the subsequent pages. The potentiometer of
the DVC6000 is removed from the back plane and replaced with a Hall effect sensor
that is potted into the new DVC6200 housing design. The terminal box moves to the left of the instrument in the DVC6200 (when viewed from front); this allows for
a tighter t with small actuators and integral mount actuators like the Fisher GX
actuator.

MOC: DVC6200 and DVC6200f Digital Valve Controllers
The eldbus version of the new 6200f features a new printed wiring board and rmware required to transition to a universal Emerson microprocessor platform.
This microprocessor is designed by Emerson and is manufactured exclusively for
the various Emerson divisions. All Emerson divisions having eldbus devices use this
processor; this provides consistent behavior and functionality among all Emerson divisions. This product change will include the following improvements to the DVC6200f instrument:
Back-up LAS - Every eldbus segment has a link active scheduler (LAS). There is
also a designated device that will act as the backup LAS if the primary LAS were to become unavailable. The DVC6200f has the ability to act as the back-up LAS.
Faster block execution - Faster block execution allows the user to schedule a faster macro cycle (better control) and an increased number of loops per segment (reduced wiring).
