DESCRIPTION
This workshop is for engineers and technicians who need a practical and extensive knowledge of the design and troubleshooting of Industrial Ethernet networks, as well as the selection, installation, and configuration of components such as routers and switches. It deals in-depth with the underlying TCP/IP protocols, and specifically addresses both design and configuration issues related to IPv4 and the more recent IPv6. It also covers the more advanced aspects and applications of Ethernet such as advanced switching and routing, CCTV over IP, OPC and Modbus/TCP over Ethernet, industrial security, intrinsically safe applications, switched rings (included the latest IEC 62439-3 redundant ring standard), and highly-deterministic Ethernet-based field buses (e.g. for servo control) capable of 1 millisecond repetition rates and jitter of less than 1 microsecond. A strong practical hands-on focus with real equipment as detailed in the list of practical sessions ensures you apply and test out your knowledge and skills. http://www.idc-online.com/content/advanced-tcpip-based-industrial-networking-engineers-and-technicians-20

Bluebook (V2) versus IEEE 802.3
IEEE 802.3 Ethernet Blue Book 2IEEE 802.3 supports bus and star topology
Supports only bus topology
Supports both baseband and broadband signalling
Supports only baseband signalling
Data Link Layer (DLL) divided into LLC and MAC
No division of DLL
Consists of 7 octets of preamble plus SFD
Consists of 8 bytes with no separate SFD
The Type field of Ethernet V2 is represented here as Length field in data frame
Has a Type field in data frame

Ethernet Addressing and MAC
12-character hexadecimal string (0-9, plus A-F, capitalized)
Uniquely identifies all Ethernet devices which are pre-programmed into the devices
Ethernet network uses two MAC addresses that identify the source and destination of each frame

Variants of Ethernet
10 Mbps Ethernet IEEE 802.3 standard defines a range of cable types that
can be used IEEE 802.3 standard supports various cable media as
follows• 10Base2: thin coaxial cable (RG-58), 10 Mbps and single cable
bus
• 10Base5: thick coaxial cable (RG-8), 10 Mbps and single cable bus
• 10BaseT: UTP cable (Cat3), 10 Mbps and hub topology
• 10BaseF: optical fibre cable, 10 Mbps, twin fibre and point-to-point

Intrinsically Safe (Ex) Ethernet
Intrinsically Safe (Ex) Ethernet systems Offers high speed along with explosion protection Current and voltage are limited to a safe level to prevent
sparks Typically used for 4mA to 20mA signals Also used for field buses such as Profibus PA or
Foundation Fieldbus H1 Isolators isolate the intrinsically safe circuits in zone 1
from the non-intrinsically safe circuits Flameproof enclosures, specially designed cable glands,
and connectors are used

Power over Ethernet (PoE)
PoE splitter (Courtesy: Infomart)
PoE technology Describes how to safely transfer electrical power and
data from a central location to remote devices over standard data cables
A ‘Splitter’ on the receiving side picks the power off the bus to power a non-Ethernet device

Point-to-Point Protocol over Ethernet (PPPoE)
Point-to-Point Protocol (PPP)
A Data Link layer protocol
Mostly used to establish a direct connection between two networking nodes
PPP is used over serial cable, phone line, trunk line, cellular telephone, specialized radio links, fiber optic links and by ISPs for dial-up internet access
