Glossary

ASIC
Application-Specific Integrated Circuit is an integrated circuit (IC) customized for a particular
use, rather than intended for general-purpose use.
EMC
Electromagnetic compatibility (EMC) is the branch of electrical sciences which studies the
unintentional generation, propagation and reception of electromagnetic energy with reference
to the unwanted effects (Electromagnetic Interference, or EMI) that such energy may induce.
The goal of EMC is the correct operation, in the same electromagnetic environment, of different
equipment which use electromagnetic phenomena, and the avoidance of any interference
effects.
HART
HART Communication is a bi-directional industrial field communication protocol used to
communicate between intelligent field instruments and host systems. HART is the global
standard for smart process instrumentation and the majority of smart field devices installed in
plants worldwide are HART-enabled. HART technology is easy to use and very reliable
IP
An IP (Ingress Protection) number is used to specify the environmental protection of enclosures
around electronic equipment. These ratings are determined by specific tests. The IP number is
composed of two numbers, the first referring to the protection against solid objects and the
second against liquids. The higher the number, the better the protection. For example, in IP67
the first Number (6) means that the device is totally protected against dust, and the second (7)
that it is protected against the effect of immersion between 15cm and 1m
MODBUS
MODBUS is a serial communications protocol intended for use with programmable logic
controllers (PLCs). MODBUS allows for communication between many devices connected to the
same network, for example a system that measures temperature and humidity and
communicates the results to a computer. MODBUS is often used to connect a supervisory
computer with a remote terminal unit (RTU) in supervisory control and data acquisition systems.
NAMUR
Normenarbeitsgemeinschaft für Meß- und Regeltechnik in der Chemischen Industrie (NAMUR).
NAMUR is a group representing the interests of the chemical industry which create standards for
instrumentation and electrical devices used in industrial plants.
