PROFINET

PROFINET
PROFINET is an open standard (IEC 61158/61784) for industrial automation based on
Industrial Ethernet. PROFINET uses existing IT standards and allows end-to-end
communication from the field level to the management level as well as plant-wide engineering.
PROFINET also has the following features:
● Use of TCP/IP
● Automation of applications with real-time requirements
– Real-Time (RT) communication
– Isochronous Real-Time (IRT) communication
● Seamless integration of fieldbus systems
You configure PROFINET in "System > PROFINET (Page 208)".
PROFINET IO
Within the framework of PROFINET, PROFINET IO is a communications concept for
implementing modular, distributed applications. PROFINET IO is implemented by the
PROFINET standard for programmable controllers (IEC 61158-x-10).

VLAN

Network definition regardless of the spatial location of the nodes
VLAN (Virtual Local Area Network) divides a physical network into several logical networks that
are shielded from each other. Here, devices are grouped together to form logical groups. Only
nodes of the same VLAN can address each other. Since multicast and broadcast frames are
only forwarded within the particular VLAN, they are also known as broadcast domains.
The particular advantage of VLANs is the reduced network load for the nodes and network
segments of other VLANs.
For the identifier which frame is assigned to which VLAN, the frame is expanded by 4 bytes
(VLAN tagging). Apart from the VLAN-ID this expansion also includes priority information.
