9.2 Determining the MAC address
To determine the MAC adress of the evaluation unit several options are available .
1 . Finding the MAC address on the type label
The type lable is located on top of the evaluation unit above the AUX connector .
2 . Scanning the MAC address with a data matrix code reader
The code is located on the type label and can be read with any data matrix code scanner .
9.3 Connection concept of the EtherCAT interface
The evaluation unit can be integrated in an EtherCAT network over the connectors "EtherCAT In" and
"EtherCAT Out" . The integrated EtherCAT switch allows to build a line structure . An external switch is not
required . The evaluation unit has only one MAC address, enabling the system to address the evaluation
unit with a single IP address . Both Ethernet ports have the same functionality .
