1-1 Introduction to PROFINET
As a common solution for the industrial communication, the PROFIBUS and PROFINET International
organisation introduced the PROFINET Industrial Ethernet standard.
PROFINET is the innovative and open standard for Industrial Ethernet. PROFINET satisfies all require-
ments for automation technology. With PROFINET, solutions can be implemented for factory and pro-
cess automation, for safety applications and for motion control. PROFINET is now standardized in IEC
61158 and IEC 61784.
The use of PROFINET minimizes the cost of installation, engineering and commissioning.
PROFINET IO
The IO data of field devices are cyclically transmitted to the process image of the PLC.
The PROFINET IO device model is based on the PROFIBUS implementation. The characteristics of
the field devices are described via a General Station Description (GSDML) on an XML basis.
The distributed field devices are allocated to a controller during configuration.
PROFINET CBA
The PROFINET component model has its application in distributed automation systems. This is mainly
used for intelligent field devices with programmable functionality as well as controllers. PROFINET CBA
divides distributed, complex applications into autonomous units of manageable size.
A distributed automation system based on these autonomous units simplifies the modularization of
plants and machines, permitting separate and cross-vendor development.
