Basic chemicals made from oil or natural gas liquids feedstocks;
commonly used to manufacture plastics and gasoline. Examples are
ethylene and propylene.
Object-Oriented Programming. The XFC/XRC architecture incorporates
an object-oriented approach.
See Ole for Process Control.
A complete break in a metal conductor path.
The difference in potential between the terminals of a cell/battery when
the circuit is open (no-load condition).
A single NPN transistor with the base connected to the logic driving
circuitry and with the emitter grounded. The collector is the output pin of
the gate.
A widely accepted application-programming interface (API) for
database access. It is based on the Call-Level Interface (CLI)
specifications from X/Open and ISO/IEC for database APIs and uses
Structured Query Language (SQL) as its database access language.
Using ODBC, you can create database applications with access to any
database for which your end-user has an ODBC driver. This allows
access for authorized users to databases over any network, including
the Internet. The SCADA system provides an ODBC driver, making the
database accessible to authorized users anywhere on a corporate
network, or even over the Internet if the network is properly configured.
Base-level software that controls a computer, runs programs, interacts
with users, and communicates with installed hardware or peripheral
devices.
Totalflow enclosure designed to house optional power and
communication devices.
Device to record differential pressure measurement which uses a steel
plate with a calibrated hole or orifice to generate a drop in pressure
between the two sides of the plate. Also the primary element of the
meter run.
A plate of non-corrosive material which can be fastened between
flanges or in a special fitting perpendicular to the axis of flow and
having a concentric circular hole. The primary use is for the
measurement of gas flow.
Boolean algebra logical function. Described as the addition or summing
of switches or inputs, in the case of Boolean elements, the 0 and 1
represent two possible states of a premise or hypothesis: True or False,
On or Off. When adding Boolean elements not real numbers, you will
find these results:
1 or 1 = 1
1 or 0 = 1
0 or 1 = 1
0 or 0 = 0
A flat ring made of rubber or plastic, used as a gasket.
