Installing and Upgrading ENVOX r Configuration Software on DEC VAX and DEC AXP Systems (Revision B — May 1998)
Group
A PROVOX point type. A group point
controls as many as 8 DCD points so that
they work in unison. A Group point uses
a Group templa te which contains up to
16 setpoints for driving DCD point
setpoints. the user defines group
templates as p art of system
configuration.
Group Display
A set of 12 point templates that appear
together on a PROVOX console screen,
so that an operator can see at a glance
the most important information about 12
different points. During system
configuration, the user establishes the
number of group displays, as well as
which point faceplates make up each
group display.
HART In strument Loca tor Tool (HILT)
The HART Instrument Locator Tool (HILT)
is a standalone utility run from the
ENVOX command line. The utility gathers
information about smart field devices
connected to a PROVOX system through
configured controllers. HILT stores the
collected information in a Comma
Delimited Values (CDV) file specified by
the user so that Asset Management
Solutions (AMS) can correctly address
the instruments when the need arises.
HP-UX

into an ENVOX database from CDV file
forma t.
Information stream

PROVOX instrumentation system, that
handles from one to eight control loops.
ISQL
SYBASE’s stand-alone utility program for
database queries.
IO or I/O
Acronym: Input/Output
Item
A general term for an ENVOX database
entity. Items include device definitions,
points, and templates.
LCP

Load
A software-initiated action on a database.
The term refers to the SYBASE database
load function and not the Open Database
load utilities embedded in ENVOX
software.
Locks
