Tab: EtherCAT Slave – EoE Settings

This tab is used to configure the communication settings for the individual slaves that support Ethernet over EtherCAT (EoE).

Requirement:

When using EtherCAT, the Microsoft Loopback Adapter has to be installed as a virtual Ethernet adapter. Installation instructions can be found online.

Table 36. Settings

Virtual Ethernet Port	: Enables the EOE functionality of the slave. A unique Virtual MAC ID has to be defined.
Virtual MAC ID	Input field for the Virtual MAC ID
Switch port	: The device acts as a switch. No additional network settings are required.
IP port	: The device acts as an IP port. The IP Settings have to be configured.

Table 37. IP Settings

The Ethernet communication parameters have to be set according to the parameters of the virtual Ethernet adapter.
IP address	IP address of the slave in the network (length: 4 bytes) The IP port has to be in the same range as the virtual Ethernet adapter. For example, if the address of the network adapter is 192.168.1.1 and the subnet mask is 255.255.255.0, then the IP port has to be in the range from 192.168.1.2 to 192.168.1.254.
Subnet mask	Subnet mask (length: 4 bytes)
Default gateway	Default gateway (length: 4 bytes)
DNS server	IP address of the DNS server
DNS name	Name of the DNS server

Supported operating systems and CODESYS controllers:

Microsoft Windows: CODESYS Control RTE: Full support with multiple network adapters. A separate EoE access is automatically available for each EtherCAT Master.
Microsoft Windows: CODESYS Control Win: Usage via Microsoft Loopback Adapter. There is only one EoE access, which means that only one EtherCAT Master can use EoE.
Linux usage via Linux Tap Device: There is only one EoE access, which means that only one EtherCAT Master can use EoE.
Other operating systems are currently not supported. Therefore, there is no EoE option here.
