PROFINET IO
Heterogeneous communication and engineering model for real-time
communication between PROFINET components. PROFINET IO, for example,
provides protocol elements for cyclic transfer of productive data.
PROFINET component
With PROFINET CBA: Software representation of a technological module with
defined functionality. An automation system is made up of several PROFINET
components.
A PROFINET component always includes a technological function and the
corresponding device.
SIMATIC IMap
