L
LAN (Local Area Network)
A LAN is a spatially limited, local network for permanently linking com-
puters over shorter distances. Data transfer can take place via
ETHERNET
,
Token Ring and FDDI, as well as wireless (WLAN).
Library
Collection of Modules available to the programmer in the WAGO I/O PRO
CAA programming tool for creating control programs in accordance with
IEC61131-3.
LON (Local Operating Network)
LON is used as a
fieldbus
for building automation. It was developed 1990 by
Echelon and enables, as does KNX, the communication between different
devices, independent of the manufacturer and active application.
M
MIB (Management Information Base)
MIB is a collection of information about all parameters, which can be
handed over to the management software with a request via
SNMP.
This en-
ables remote maintenance, monitoring and control of networks to be per-
formed via SNMP protocol.
MODBUS
MODBUS is an open protocol based on the Master/Slave principle. The
MODBUS links the master with several clients, via either serial interface or
ETHERNET.
Three data transmission types are available: MODBUS/RTU (binary data
transmission), MODBUS/TCP (data transmission using TCP/IP packets) and
MODBUS/ASCII (ASCII code transmission).
Module
Modules consist of functions,
function blocks
and programs.
Every module is made up of a declaration part and a body. The body is writ-
ten in one of the IEC programming languages AWL (statement list - STL),
ST (structured text), AS (process structure), FUP (function plan) or KOP
(contact plan).
