PROFINET is the innovative open standard for Industrial Ethernet. PROFINET satisfies all requirements of automation technology. PROFINET enables solutions to be developed for factory automation, process automation, safety applications, and the entire range of drive technology up to and including isochronous motion control applications.
Besides the real-time capability and the use of IT technology, protection of investment also plays an important
role in PROFINET. PROFINET allows existing fieldbus systems such as PROFIBUS DP, PROFIBUS PA, ASInterface, INTERBUS, and DeviceNet to be integrated without changes to existing field devices. That means that the investments of plant operators, machine and plant manufacturers, and device manufacturers are all protected.
The use of open standards, simple handling, and the integration of existing system components has driven the
definition of PROFINET from the beginning. PROFINET is standardized in IEC 61158 and IEC 61784. The ongoing further development of PROFINET offers users a long-term view for the implementation of their automation tasks.
For plant and machine manufacturers, the use of PROFINET minimizes the costs for installation, engineering, and commissioning. For plant operators, PROFINET offers ease of plant expansion and high system availability due to autonomously running plant units and low maintenance requirements.
