2. Ethernet Basics History
First Drawing by Bob Metcalfe
1980 Digital, Intel and XEROX (DIX) publish the specification of a network technology called Ethernet I
IEEE publishes the first standard that contains parts of the DIX procedure in 1982
1984: DIX passes Ethernet II, since Ethernet I and IEEE were incompatible
Today‘s components are based on IEEE 802.3

3. Ethernet Basics Ethernet in the ISO / OSI reference model
The Ethernet specification encompasses Layers 1 and 2 of the reference model:
Data Link Layer:
Logical Link Control (LLC)
Connection to higher sub-layers

Grouping of the data (into frames)
Error checking (CRC)

5. Ethernet Basics Network access procedures CSMA/CD
CS - Carrier Sense
MA - Multiple Access
CD - Collision Detection
Collision

6. Ethernet Basics Network access procedures CSMA/CD
CS – Carrier Sense
Every node checks to see if the transmission medium is free
MA – Multiple Access
Every node has equal access to the transmission medium and transmits when the line is identified as free
A message frame propagates equally in all directions
CD – Collision Detection
If two nodes transmit simultaneously, the two message frames collide
In physical terms, this means an increase in voltage caused by overlap of the two frames
All nodes register this collision
The transmitter immediately aborts by destroying the frame
Access begins again after a statistical waiting time

7. Ethernet Basics CSMA/CD consequences
Collision
This is provided for in the procedure and therefore not a fault
Reduces the effective data throughput
When do collisions cause faults?
If too many nodes are on the network
If the nodes send too many packets or packets that are too long
Marginal conditions for the functioning of CSMA/CD
A message frame propagates evenly across the entire network
Since the transmitting node has to invalidate the frame following a collision, the packet must not be transmitted fully when a collision occurs.
Minimum length for a message frame: 51.2 ms
This results in the following length for the shortest Ethernet message frame: ms at 10 Mbit/s = 512 bits = 64 bytes
Restricted expansion: collision domain

8. Ethernet Basics Collision domain
The collision domain
describes the range of expansion in the network within which the CSMA/CD access procedure functions securely.
is an area in which all nodes share the performance of the network
has 1024 nodes
Decisive factors
Propagation speed of the signal (approximately 5ns/km)
Length of the shortest message frame (64 bytes)
Maximum expansion (e.g. 4520m at 10 Mbit/s)
Actually achievable network expansion depends on
The medium used
Type of active components (delays in throughput)
Network configuration
Observance of signal runtime
Observance of rules

Load decoupling: restriction of local traffic (transport decision based on the MAC address)
Filtering: faults limited to collision domain Invalid packets (FCS error, frame length) are rejected
Propagation of number of stations and expansion
Redundancy through Spanning Tree protocol
Nominal data rate at every port making parallel communication relationships possible
Address table per port, self-learning

18. Industrial Ethernet Ethernet/Fast Ethernet comparison
Ethernet/Fast Ethernet differences
Network span of a hub-based Fast Ethernet is significantly smaller Ethernet: m Fast Ethernet: m
No Fast Ethernet specification for coaxial cables
Different configuration rules (e.g. fewer repeaters/hubs permitted)

19. Ethernet Basics Ethernet/Fast Ethernet in comparison
Ethernet/Fast Ethernet similarity
same frame format
same medium access method CSMA/CD
same cables (twisted-pair and fiber optic)
easy migration to higher performance
existing Ethernet knowledge can still be used
wide acceptance of Fast Ethernet

20. Ethernet Basics Autonegotiation/autosensing
Automatic calculation of the data rate (10 or 100 Mbit/s)
Unification of other features (e.g. duplex mode) according to priorities (best shared performance)
Connection only if compatible

23. Ethernet Basics Switching procedures
Cut-through switching
Transport decision is made as soon as the target address is read in, so extremely fast (typically 40 usec)
Invalid frames are not filtered (not till the terminal devices)
Store & forward switching
Data packets first stored temporarily then switched
Storing enables filtering of invalid frames or broadcasts -> clean networks

Data traffic
Switched LAN
Each individual segment has the full performance/data rate
Simultaneous data traffic in several segments; several message frames
Filtering: Local data traffic remains local; only selected data packets cross segment boundaries
Shared LAN
All nodes on the network share network performance/data rate
All data packets go through all segments
Only one message frame on the network at any one time
Collisions reduce the efficiency of the network to approximately 40%

26. Ethernet Basics Half duplex/full duplex
The nodes either send or receive data at any one time, e.g. classic walkie-talkie radio
Full duplex:
The nodes can send and receive data simultaneously, e.g. classic telephony
Requirement for full duplex
Medium with separate send and receive lines: fiber optic or twisted-pair (not coax)
Nodes can store data packets temporarily
Collision-free operation

Other competitor systems have chosen an optimized UDP stack for real-time applications. However, this solution goes outside the UDP standard without being able to decisively reduce the tremendously large program stack.
Our PROFInet solution, however, is a slimmed-down solution based on PROFInet's own performance capability which builds directly on Layer 2. This approach creates an integrated solution with the performance capabilities needed for both production automation and motion control.
