2.2. Local Area Network (LAN)
A local area network (LAN) is a group of computers and associated devices that
share a common communications line or wireless link. Local area networks are built
with hardware such as Ethernet cables, network adapters, hubs and managed or
unmanaged switches. Wireless LAN and other more advanced LAN hardware
options also exist. LANs connect MicroSCADA workstations and SYS 600
computers and other supported devices like IEDs using IEC 61850 protocol. Each
individual device connected to LAN has its own IP address. They are able to access
data and devices anywhere on the LAN, they can share resources on LAN. Users
can also use the LAN to communicate with each other. There are many different
types of LANs. Our scope is on Ethernet and used protocol is TCP/IP. See detailed
installation instructions from corresponding Windows Operating System manual.
2.2.1. Network interface card
Each computer on the LAN contains a network interface card and software for
handling the card and the used protocols.
Insert the network interface card before installing the Windows operating system.
Most computers are equipped with a built-in network interface card. The LAN
software is installed and configured during the operating system installation.
2.2.2. IP addresses
The communication protocol supported by MicroSCADA is TCP/IP.
Each node or host in a TCP/IP network has an unique identifier, also called an IP
address. The IP address is composed of four numbers in the range from 0 to 255.
The numbers are separated with dots. For example: 192.168.0.1
The smallest LAN can have exactly two computers, a large LAN can accommodate
many thousands of computers. Because every computer on an IP network must have
a unique IP address, careful planning of IP addresses to the whole system is
important. You should remember to take care of the future needs in address areas
when planning large networks.
There are some special IP addresses. 127.0.0.1 is known as the loopback address
and it always refers to the local computer. Hostname used for the address is
'localhost'.
Use static addressing in MicroSCADA networks.
The IP addresses of the MicroSCADA Pro base system and workplaces must
comply with the addresses of other nodes on the network. Consult the local area
network administrator for valid IP addresses and other LAN configuration issues.
This document does not include planning guide for TCP/IP networks. You can find
these guides from Microsoft or other Internet sites.
