GE Ethernet interfaces can communicate with each other in several ways:
TCP/IP Protocol
The TCP/IP protocol is the most commonly used network protocol for communication between different types of devices. The TCP/IP protocol is the most common network protocol used today to communicate between different types of devices. The TCP/IP protocol can be used to transfer data when communicating between GE Ethernet interfaces.

GE Proprietary Protocols
GE also offers a number of proprietary protocols for communication between GE devices. These proprietary protocols can be used to transfer data when communicating between GE Ethernet interfaces.

GE Industrial Ethernet Protocol
The GE Industrial Ethernet Protocol is a set of industrial network protocols developed by GE that can be used for communication in industrial control systems. The GE Industrial Ethernet Protocol can be used to transfer data when communicating between GE Ethernet interfaces.

The specific communication method can be selected according to the specific requirements of the equipment.

The following are some examples of communication between GE Ethernet interfaces:
Communication using the TCP/IP protocol
In this case, both GE Ethernet interfaces need to be configured with IP addresses and subnet masks. Then, data can be transferred using the TCP/IP protocol.

For example, the IP addresses of the two GE Ethernet interfaces are 192.168.1.1 and 192.168.1.2. These interfaces can establish a connection via the TCP protocol, and then transfer data using the IP protocol.

Communicating Using GE Proprietary Protocols
In this case, both GE Ethernet interfaces need to be configured with the parameters of the proprietary protocol. The proprietary protocol can then be used to transfer data.

For example, GE offers a proprietary protocol called EGD. Two GE Ethernet interfaces can establish a connection using the EGD protocol and then use the EGD protocol to transfer data.

Communicating Using the GE Industrial Ethernet Protocol
In this case, both GE Ethernet interfaces need to support the GE Industrial Ethernet protocol. The data can then be transferred using the GE Industrial Ethernet protocol.

For example, GE offers an industrial Ethernet protocol called Profinet. Both GE Ethernet interfaces can establish a connection via the Profinet protocol and then use the Profinet protocol to transfer data.
