The Physical Layer defines the physics of getting a message from one device to another. Is responsible for an error free transmissionConverts bits into signals for outgoing messages and signals into bits for incoming onesThis is the most important area in terms of troubleshooting and operations

Fiber Optic transmissionFiber optic cable has huge advantages over copper

It’s immune to Electromagnetic InterferenceSupport of long distances

Fiber is made fromGlass – High quality, used for long distances or high speedPlastic – Cheaper, used for short distances and low speedGlass core + plastic cladding – compromize, fieldbusses only

There are 3 basic light sourcesLEDs – low cost, used for MMFELEDs - medium cost, used for SMF, cheaper than LDs, no Laser protection measures neededLaser, Laser Diodes LD – used with SMF over long distances


Fiber types 1: Multimode FiberBecause of the high dispersion, multimode fiber is only used for short distances.LEDs for glass fiber use either 850 nm or 1300 nm wavelength for transmission

Cladding diameter 125 µm

Core diameter 50µm or 62.5µm


Fiber types 2: Singlemode FiberCapable of transmission rates of several Tbit/sUse of ELEDs at 1300 nm wavelength till about 30 km, for longer distances lasers/LDs with 1550 nm as transmittersQuoted as between 8/125 µm and 10/125 µm cable, depending on manufacturer

Cladding diameter 125µm Core diameter 8µm or 10µm


Ethernet Data Link Layer


OSI Reference Model (Data Link)The Data Link Layer provides the rules for converting electrical signals to data, error checking, physical addressing and media access control.Handles the delivery of frames from sender to receiver through the physical layer.

SwitchesThe switch is a device in layer 2 of the ISO/OSI reference model. Each port of a switch can

operate in half-duplex or full-duplex mode. This means each port comprises its own segment (collision domain).

Erroneous packets or collisions in connected segments are not forwarded by a switch and do not reach other connected segments.

Industrial Ethernet


ETHERNET: The PresentETHERNET today is not the same when it was invented 30 years ago

What’s the improvements?

- Higher bandwidth -10Mbit/100Mbit/1Gbit/10G

- Full-duplex communication → without collisions

- Switching

- Prioritization and flow control

- VLANs - Virtual Local Area Networks


Why Industrial ETHERNET?• The fieldbuses available on the market use different types of physical

transmission; as a result bus-specific infrastructure components are necessary and the interface to the higher level networks requires so-called “gateways”.

• Ethernet offers a dramatic increase in bandwidth compared to fieldbuses (e.g. Profibus DP up to 12 Mbit/s – Ethernet up to 10Gigabit/s).

• Ethernet makes vertical integration possible(From ERP down to the station controller).

• Ethernet is an open protocol.

• The majority of fieldbus manufacturers have developed their own protocols that build on standard Ethernet: Modbus/TCP, EtherNet/IP, ProfiNet, FF HSE, Powerlink.
