Introduction to XML (2)
XML is not a programming language !
XML is not a data base !
XML does not include semantics or services !
Applications like IEC standards include semantics or services
IEC 61970 (CIM) defines a XML scheme representing a power systemmodel
IEC 61850-6 defines a XML scheme representing substation and IED configuration model

SCL files: ICD and SCD
With SCL, all relevant information can be written into a text file in accordance with a standardized structure based on XML:
Each IEC 61850-compliant device now has to provide such a file, the so-called device description (ICD). This file defines the configuration of the device as well as its functioning and communications capabilities.
Analogously, the station description contains information on the network structure of a station, the assignment of the devices to the primary technology and the station-internal communication (SCD).

Ethernet Basics
Ethernet:Ethernet is a large, diverse family of frame-based computer networking technologies that operates at many speeds for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the physical layer, through means of network access at the Media Access Control (MAC)/Data Link Layer, and a common addressing format.
MAC-Adresse (Media Access Control)Worldwide unique physically hardware address of a NIC (network interface card). Will be provided by the manufacturer. The first three octets (in transmission order) identify the organization that issued the identifier and are known as the Organizationally Unique Identifier (OUI). The following three octets are assigned by that organization in nearly any manner they please, subject to the constraint of uniqueness.
DHCP (Dynamic Host Configuration Protocol)DHCP is a protocol used by networked computers (clients) to obtain IP addresses and other parameters such as the default gateway, subnet mask, and IP addresses of DNSservers from a DHCP server. It facilitates access to a network because these settings would otherwise have to be made manually for the client to participate in the network.This service is out of scope in IEC 61850.

Ethernet Basics
Unicastdata packets will be transmitted from one sender to one receiver,e.g. Inforeport
Multicastdata packets will be transmitted from one sender to one or more receiver ,e.g. GOOSE packets use multicasting
Broadcastdata packets will be transmitted from one sender to all receivers in the same subnet,e.g. DHCP or ARP

Ethernet Basics
IP-Address:An IP address (Internet Protocol address) is a unique address that certain electronic devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address. Any participating network device—including routers, computers, time-servers, printers, Internet fax machines, and some telephones—can have their own unique address.Continuous IP-Addresses are grouped to subnets. A subnet is a specified partof the IP-address. The choice is done by the subnetmask
Subnetmask:The subnetmask determine which part of the IP-address is the network portionand which part is the host portion. Subnet masks consist of a series of 1s in binary followed by 0s. The 1s designate that part of the address as being part of the network portion and the 0s designate that part as being part of the host address (logical AND interconnection).Subnet masks do not have to fill a given octet. This allows a classful network to be broken down into subnets

IP-address and Subnetmask
IP-address consists of subnet-address and host-address.
With the subnetmask the max. amount of hosts is determined for thissubnet.
05/2007 38
Power Transmission and Distribution
Power AutomationProgress. It‘s that simple.
IP-address and Subnetmask
example:
device 1: IP-address 192.168.1.23subnetmask 255.255.0.0
device 1 is part of subnet 192.168 (mask255.255.0.0) and has host-address 1.23
device 2:IP-address 192.168.1.24 subnetmask 255.255.0.0
device 2 is part of the same subnet and has host-address 1.24
device 3 is part of subnet 192.168.2 (mask 255.255.255.0) and has host-address 34 and is therefore not in thesubnet of device 1 and 2
device 3:IP-address 192.168.2.34
subnetmask 255.255.255.0
Important: the subnet part of the IP-address has to be identical within the same subnet(192.168). The host address(1.23 / 1.24) has to be unique.
05/2007 39
Power Transmission and Distribution
Power AutomationProgress. It‘s that simple.
network classes
In former times the classes were distinguished via the 1st block of the IP-address (without subnetmask)
1 … 127 class A network, 16.777.214 hosts (Block 2 -4)128 … 191 class B network, 65.534 hosts (Block 3 and 4)192 … 223 class C network 256 hosts (Block 4)224 … 255 class D/E network Multicast/reserved
Private address-ranges are still preserved and won‘t be routed in the internet. They can be used by yourself without restrictions.
class A: 10.0.0.0 bis 10.255.255.255class B: 172.16.0.0 bis 172.31.255.255class C: 192.168.0.0 bis 192.168.255.255

Redundancy in Layer 2 networks
Layer 2 redundancy algorhythm: RSTP (Rapid SpanningTree)
RSTP works with prioritiesThe switch with the highest bridge-priority (lowest value) is theso-called root-bridge. At the root-bridge the station master SicamPAS should be connected. All other switches are the so-called„Designated Switches“ .The determination of the logical cut in the ring will be done via the pathcosts (parameter „cost style“). The way with the lowestpathcosts will be chosen to the root bridge.

Power AutomationProgress. It‘s that simple.
Redundancy in Layer 2 networksGeneralThe switches are connected to each other in ring configuration. Thus it is assured that in case of failure a redundant switch over occurs. Logically those rings are open to prevent cycling telegramswithin a ring.Via the priority of the switches the data flow within the configuration can be managedand the traffic load be influenced.
1.) Approachsame priority for all switches (no changes)the order of the priorities will be choosen automatically by the MAC-addresses-> random allocation of the priorities-> unbalanced network load
2.) Approachdetermine the root-bridgebridge priotity will be set to zero (high Prio)
-> what happens in case of failure, where is the new root ?
3.) Approach (recommendation)Each switch gets its own priority depending on locationAdvantage:The complete network is known and data flow can be managed secretly.Disadvantage:Each switch has to be set individually. If you change the configuration, all switches must beparametrized.

EN100-Module electric
Ethernet module EN100 with RJ45 interfaces forinternal installation
Ethernet module EN100 with DSUB interfaces forsurface installation
The socket of each of the two channels Ch1 and Ch2 has one yellow and onegreen LED to indicate the status of the channel. The yellow LED indicates thetransmission rate of the link. If the LED is on, the transmission rate is 100 Mbps, otherwise it is 10 Mbps. The green LED indicates that the link is up on the datalink layer. The green LED switches on and off with each telegram received.

Internal switch:EN100-module optical
Ethernet module EN100 with ST interfaces for internalinstallation
The module with optical interface has the interfaces shown as above. The interface design conforms with IEEE802.3, 00Base-FL. It provides two channels, each with one transmitter and onereceiver. The connectors are made of metal and conform withthe ST standard. The module has no LEDs but uses the devicedisplay for visualization.
