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
22© 2007 Fieldbus Foundation
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
23© 2007 Fieldbus Foundation
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

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.

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
30© 2007 Fieldbus Foundation
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.
