As a common solution for the industrial communication, the PROFIBUS International organisation introduced
the PROFINET Industrial Ethernet standard. PROFINET is the next step for building on the current:
•
•
PROFINET is the innovative and open standard for Industrial Ethernet. PROFINET satisfies all requirements for
automation technology. With PROFINET, solutions can be implemented for factory and process 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
Distributed field or I/O Devices are integrated through PROFINET IO. This uses the usual IO view of
PROFIBUS DP, whereby 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, consisting of insertion (slots) and
groups of I/O channels (subslots). The characteristics of the field devices are described via a General Station
Description (GSD) on an XML basis.
The installation, monitoring and maintenance of PROFINET IO will be familiar to engineers accustomed to
PROFIBUS DP. 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.
PROFINET based on a component model is described using a PROFINET Component Description (PCD),
which is XML-based.
PROFIBUS DP, the well-known and established fieldbus;
Industrial Ethernet.
