5. CONFIGURATION
State Machine: The buttons Init, Pre-Op (Pre-Operational), Op (Operational) and Safe-Op (Safe-Operational) can be
used for debugging purposes. They make the slave transition to the respective state.
File access over EtherCAT: If you want to transfer firmware files to or from the Slave, you have to click on the Bootstrap
button to switch the slave in Bootstrap Mode. The Download and Upload of firmware files can be done with the
corresponding buttons. A dialog to save or open the firmware file will open. In this dialog, a string and password are
required to execute the file transfer. This information is provided by the slave device and documented in the datasheet of
the slave.
E2PROM access: The slave configuration can be read from, or written to, the E2PROM. Here, as well as for the firmware
transfer, a dialog to open or save files will open. The command Write E2PROM XML can be used to write the Slave
configuration directly from the XML file to the device. This command is only enabled if there’s configuration data in
the XML file (section <ConfigData>).
5.5.12.4.10. EtherCAT Slave - I/O Mapping
This tab of the EtherCAT Slave configuration editor offers the possibility to assign the project variables to the EtherCAT
inputs or outputs. This way, the EtherCAT Slave variables can be controlled by the User Application.

5.5.12.4.11. Status and Information tabs
The Status tab of the EtherCAT Slave provides status information (e.g. ’Running’, ’Stopped’) and device-specific diagnostic
messages, also on the used card and the internal bus system.
The Information tab, presented in the EtherCAT Slave configuration editor, shows, if available, the following general
information about the module: Name, Vendor, Type, Version, Categories, Order Number, Description, Image.
5.5.13. EtherNet/IP
The EtherNet/IP is a master-slave architecture protocol, which consist of an EtherNet/IP Scanner (the master) and one
or more EtherNet/IP Adapter (the slave). The EtherNet/IP editor provides dialogs for setting parameters and for mapping
inputs/outputs to variables.
The Ethernet/IP protocol is based on CIP (Common Industrial Protocol), which have two primary purposes: The transport
of control-oriented data associated with I/O devices and the transport of other information related to the system being con-
trolled, such as configuration parameters and diagnostics. The first one is done through implicit messages, while the second
one is done through explicit messages.
