PROFIBUS Communication Solutions
PROFIBUS (Process Field Bus) was initially a bus developed
by Siemens for fieldbus communication in automation technology. In 1987,
companies and institutions joined forces with the goal of creating a standard
for field-suitable and bit-serial buses. Initially (1989), the PROFIBUS was
promoted by the BMBF (Federal Ministry for Education and Research). Nowadays,
the PNO (PROFIBUS User Organization) is the main body.
The standardization of the fieldbus interface should be the
basis for propagation of the fieldbus in manufacturing and automation
engineering. For this, a common technological concept was agreed upon, as well
as a uniform communication model. The PROFIBUS was then standardized in the
international standard series IEC 61158.
PROFIBUS is a multi-master system and permits common
operation of actuators/sensors, engineering systems, and visualization devices
on a common, real-time capable bus. Because of its low costs, the real-time
capacity, the standardization, its technological stability, and its universal
applicability, it has already become a leader on the world market. The protocol
architecture is based on the OSI layer model (ISO 7498).
