Configuring EtherCAT Terminals
Since the PROFIBUS is subject to certain restrictions, EtherCAT Terminals cannot be configured via the
GSD file. Some EtherCAT Terminals would exceed the maximum data length solely on account of the
number of configuration data.
Configuration via the GSD file was deliberately omitted, and the EtherCAT Terminals are configured as
follows:
• Via the web interface (see: Beckhoff device manager [
}
36] ),
• Or via the PROFIBUS DPV1 services (see sample program for a TwinCAT controller: https://
infosys.beckhoff.com/content/1033/ek3100/Resources/zip/4058251659.zip).
Configuring the process image (mapping) of the EtherCAT Terminals
The process image (mapping) of an EtherCAT Terminal is configured via the GSD file, as usual. If an
EtherCAT Terminal has different mappings, the mapping is automatically set by selecting the corresponding
module in the GSD file. If an EtherCAT Terminal is added in TwinCAT, for example, you can choose
between the available mappings.
The GSD file for the EK3100 Bus Coupler must be copied into the TwinCAT directory:
• TwinCAT 2: C:\TwinCAT\Io\Profibus
• TwinCAT 3: C:\TwinCAT\3.1\Config\Io\Profibus
Or: The GSD file for the EK3100 Bus Coupler can be installed retrospectively in TwinCAT when the Bus
Coupler is added in TwinCAT (see:
Adding the EK3100 Bus Coupler in TwinCAT [ } 43] ). A corresponding
prompt appears in TwinCAT, which asks you to install the GSD file.

5.1 EtherCAT configurations
The EK3100 is an EtherCAT master with automatic configuration. This means that all EtherCAT Terminals
must be present when the system is switched on. Since the boot-up of the EK3100 generally takes
considerably longer than the start-up of the EtherCAT slave devices, the latter can be operated on the same
power supply. With decentralized EtherCAT slaves, care must be taken that they are switched on earlier or
at the same time as the supply voltage.
