2.4 Configuration
General instructions on commissioning
Configuration of the CPX terminal demands a very accurate
procedure, as different configuration specifications are some
times necessary for each slave, i.e. for each device and each
Box" on the EtherCAT network, due to the modular
structure.
Note here the specifications in the sections which follow
(asfrom section 2.4.1 regarding the configuration, and
insection 2.3 as well as 2.4.2 regarding the addressing).
2.4.1 Registering slave properties (XML file") in the configuration
program
When you commission a new EtherCAT slave, i.e. an EtherCAT
device the first time, you must inform your configuration and
programming software about certain properties of the slave.
The properties of the various slaves are usually administered
by the configuration program in a configuration file, i.e. the
EtherCAT Device Description File (in Beckhoff TwinCAT
referred to as System Manager Tree Item Description).
Device Description File
(XML file") This file or their corresponding contents have been made
available using the Extensible Markup Language" (XML).
Therefore, the EtherCAT Device Description File is commonly
known as XML file".
The XML file is used to identify the bus node in the EtherCAT
network. Using the XML file, basic properties of the EtherCAT
device as well as information concerning the manufacturer
are provided to the configuration program.
