Appendix F Device Description Installation

Overview

Several support files are required for the DVC6200f digital valve controller. They are:
D Device Description (DD) files—These files define the data interface to the digital valve controller (file extensions
.sym and .ffo).
D Capabilities File—These files allow a host to configure the control system off‐line (e.g., without having a device
physically attached to the host) (file extension .cff).
D DeltaV Registry File—This file is used by DeltaV to define the device interface (file extension .reg)
D DeltaV fhx File—This file is used by DeltaV to define the device and the data interface to the device (file extension
.fhx).
D DeltaV Windows Resource File—These files define the user interface for the device for DeltaV and include the
definitions for the transducer block interface and the resource block interface (file extension .dll).
The directory structure defined by the Fieldbus Foundation for device descriptions is as follows:
....\xxxxxx\yyyy\rrddcc.eee
where:
....\
is the path to the DD structure as implemented by the host system. This is typically defined as the base path
to the DD since access to the specific device DD is predefined from the base folder. For a DeltaV system, the
DDs are included with the support files and are located in a folder named "amsdevices." For other hosts, the
Fieldbus Foundation defines a folder named "release" that is included with the CD‐ROM, however, you do not
need to retain this folder name.
xxxxxx is the 6‐digit hexadecimal equivalent of the manufacturer's identification number as defined by the Fieldbus
Foundation. Fisher Controls' ID number is 5100 (or in the folder format 005100). This number is also stored in
the instrument Resource Block in the parameter Mfg ID (parameter name MANUFAC_ID).
yyyy
is the 4‐digit hexadecimal equivalent of the device type, as defined by the manufacturer. For example, the
device type for the DVC6200f digital valve controller is 4602. This number is stored in the instrument
Resource Block in the parameter Device Type (parameter name DEV_TYPE).
rr
is the 2‐digit hexadecimal equivalent of the device revision, as defined by the manufacturer. It is stored in the
instrument Resource Block in the parameter Device Revision (parameter name DEV_REV).
dd
is the 2‐digit hexadecimal equivalent of the device description (DD) revision that applies to the device, as
defined by the manufacturer. The host will always use the latest version of the DD that it finds for a particular
device revision. When part of the name of a capabilities file, this value is always the same as the value of the
DD_REV parameter stored in the Resource Block of the instrument. The value of the DD_REV parameter
represents the earliest version of the DD that is compatible with the device revision of the instrument.
cc
is a 2‐digit hexadecimal equivalent for the capabilities files (.cff) revision, as defined by the manufacturer. The
latest revision of the capabilities files, for a particular device revision, is the file with the largest value for this
number.
eee
is the file extension. At this time, five extensions exist for files, they are:
D .sym—This extension denotes a device description (DD) symbol file as defined by the Fieldbus
Foundation.
