h Draws your attention to interesting tips and
supplementary information.
For greater clarity, the name of the current chapter is shown in the
header of the left-hand page and the name of the current section
in the header of the right-hand page. This does not apply to pages
at the start of a chapter and empty pages at the end of a chapter.
The manual provides the essential information required for the
access of an IEC station, such as an XC200, to other stations in the
easyNet network. The access of the IEC stations is executed by the
program containing the functions for sending and receiving data.
The functions contain structure variables, and both are described
briefly in chapter 2 and chapter 3.
The relationship between the functions and structures, as well as
their integration in the program, are shown in the chapter 4.
The possible data transfer options are described in chapter 2.
This manual is divided into the following chapters:
The easyNet network
Provides an introduction to the easyNet network,
a chapter 1, page 5.
Functions
Describes the functions and their properties,
a chapter 2, page 7.
Structures
Describes the structures, a chapter 3, page 9.
Application
Shows the possibilities for data transfer between the IEC
stations and easy stations, e.g. easy800, in the form of
examples. The functions and structures are used in these
examples, a chapter 4, page 15.
Additional information on accessing easy stations on the
network is provided in the manuals of the relevant easy
stations.
Network configuration
Describes how to configure easy stations via the first station
(Net ID 1) on the easyNet, a chapter 5, page 27.
Combination of easyNet with CAN/CANopen
Provides information on combinations of easyNet – CANopen,
CAN Direct, CAN network variables,
a chapter 6, page 31.
Routing
Shows the possibility of indirect communication between the
PC and stations via the easyNet, a chapter 7, page 33.
Bus topology
Shows different topologies, a chapter 8, page 35.
