7 Configuration
The EtherCAT master needs to be configured to drive the EtherCAT network.
One major part of the configuration is to specify the EtherCAT slave stations.
There are two ways of documenting the properties of an EtherCAT slave.
1. The basic properties are stored in an EEPROM of the slave, whereas a XML device file (ESI file)
describes the others.
2. All of the properties are stored in an EEPROM of the slave. (This method is not supported by every
OEM supplier.)
The XML device files provide EtherCAT administrators with convenient options.
EtherCAT allows both, a configuration offline and the scanning of station data via an Ethernet line (online
configuration).
The examples below are based around the standard ETG configuration tool (EtherCAT configuration tool
supplied by Beckhoff Automation GmbH) which accesses the XML device files for both offline and online
configuration.
The file to use for Kuhnke FIO is called "KuhnkeEtherCATModulesAll.xml".
Copy file "KuhnkeEtherCATModulesAll.xml" to folder C:\Programs\EtherCAT Configurator\EtherCAT or, if
you are using another tool, to the folder set for that tool.
7.1 CODESYS V3 (CODESYS Configurator)
Offline Configuration
Run CODESYS3, create a new project (default project), and select the device to become the
EtherCAT master (here: "Kuhnke FIO Controller 113 WV").
Highlight the device and pick the 3S "EtherCAT Master" from the right-click menu.
