7.2
Ethernet Connector (LAN)
The standard Ethernet RJ45 connector is galvanically isolated from the other connectors.
7.3
EtherCAT
EtherCAT function is only provided by the device variants SE and LE.
7.3.1
Connectors (X6 and X7)
If connected to a EtherCAT network, the CANnector represents a EtherCAT Slave. The connector
X6 provides the EtherCAT-Slave-OUT function and X7 provides the EtherCAT-Slave-IN function. If
the CANnector is connected to a EtherCAT Master solely, only X7 (IN) is used and X6 remains
unconnected. The EtherCAT interfaces are galvanically isolated from the other interfaces.
7.3.2
LEDs (S1, S2, S3, and S4)
LEDs S1 and S2 indicate the EtherCAT status.
