10.1 PND Functional Overview
PROFINET is the communication standard for automation of PROFIBUS and
PROFINET Intenational (PI). Many years of experience with PROFIBUS and the
widespread use of Industrial Ethernet are all rolled into PROFINET.
With its integrated, Ethernet-based communication, PROFINET satisfies a wide
range of requirements, from data intensive parameter assignments to extremely
fast I/O data transmission which enables automation in real-time.
