PROFINET IO

3 PROFINET IO
PROFINET IO is an industrial communication network based on Ethernet
that is accepted worldwide. It is based on the widely used transport protocols
TCP/IP and UDP/IP (standard). This is an important aspect for fulfilling the
requirements for consistency from the management level down to the field
level.
PROFINET IO enhances the existing Profibus technology for such
applications that require fast data communication and the use of industrial IT
functions.
