Term Definition
Negative
Acknowledgment
This refers to a response over a remote communication device, such as a
PING. Basically, saying, "I don’t acknowledge your request!" This is the
opposite of ACK. NAK is a slang term that means that you disagree or do
not acknowledge something.
NEMA
National Electrical Manufacturers Association.
Noise
An undesirable electrical signal. Noise comes from external sources such
as the AC power line, motors, generators, transformers, fluorescent lights,
soldering irons, CRT displays, computers, electrical storms, welders, radio
transmitters, and internal sources such as semiconductors, resistors, and
capacitors. Unwanted disturbances superimposed upon a useful signal
that tends to obscure its information content.
Normally Closed
Designation which states that the contacts of a switch or relay are closed
or connected when at rest. When activated, the contacts open or
separated.
Normally Open
Designation which states that the contacts of a switch or relay are
normally open or not connected. When activated the contacts close or
become connected.
Norsok
Norwegian Certification Bureau
NPT
National Pipe Thread.
NRTL
Nationally Recognized Testing Laboratory.
NX-19
American Gas Association Report referring to a specific method to
calculate the Supercompressibility factor.
OCV
See Open Circuit Voltage.
ODBC
See Open Database Connectivity.
OHM
The unit of resistance usually shown as the symbol "R". One thousand
ohms is written "k" and one million ohms is written "M". Resistance is
measured with a multimeter, set to the "ohms range".
OLE
Object Linking and Embedding. A set of system services that provides a
means for applications to interact and interoperate. Based on the
underlying Component Object Model, OLE is object-enabling system
software. Through OLE Automation, an application can dynamically
identify and use the services of other applications, to build powerful
solutions using packaged software. OLE also makes it possible to create
compound documents consisting of multiple sources of information from
different applications.
Ole for Process Control
This is a data interchange format and supporting software. Typically,
vendors (such as ABB) write OPC server drivers which can talk to their
devices. SCADA system vendors (again like ABB) write OPC clients that
can gather data from OPC Servers. The idea is to provide a universal way
to collect data into a SCADA system regardless of the equipment vendor.
This standard was developed and is maintained by the OPC Foundation.
The Totalflow Driver, TDS32, supports OPC.
