Access to process data from different levels of the factory is supported by PROFINET
communication. By using Industrial Ethernet, standard mechanisms of communication and
information technology such as OPC/XML can now be used along with standard protocols
such as UDP/TCP/IP and HTTP in automation engineering. This allows transparent access
from company management level directly to the data from the automation systems at the
control level and production level.
