為了提高性能，LAN1、LAN2和LAN3由專用微處理器核心提供服務。通過這種方式，以太網端口的服務獨立于控制器邏輯、I/O掃描和現場代理活動。EFA端口由四個微處理器核心中的兩個獨立提供服務。在較高的通信速率下，需要這種卓越的服務水平。任何前面板以太網端口都可以用于使用服務請求傳輸協議（SRTP，一種專有的通用電氣協議，主要用于與編程器通信）與PME編程軟件通信。EFA端口不能用于此目的。LAN2可以配置為嵌入式PROFINET控制器，如第2.1.6節所述。當配置為PROFINET控制器時，LAN2可以同時用于以太網協議。本主題在PACSystems RX3i PROFINET IO控制器用戶手冊GFK-2571F或更高版本中進行了討論。LAN2和LAN3各自支持一對RJ45連接器。通過這種方式，同一局域網上但以不同數據速率運行的網絡設備可以連接到適當配置的端口。要在PME編程和配置軟件與CPU之間建立以太網通信，您首先需要知道目標IP地址。

For improved performance, the LAN1, LAN2 and LAN3 are serviced by a dedicated microprocessor core. In this way, the servicing of the Ethernet ports is independent of the controller logic, I/O scanning and Field Agent activities. The EFA port is independently serviced by two of the four microprocessor cores. This superior level of servicing is required at the higher communications rates. Any of the front-panel Ethernet ports may be used to communicate with the PME programming software using the Service Request Transport Protocol (SRTP, a proprietary GE protocol, used primarily for communication with the programmer). The EFA port cannot be used for this purpose. LAN2 may be configured as an embedded PROFINET Controller, as discussed in Section 2.1.6. While configured as a PROFINET Controller, LAN2 may concurrently be used for Ethernet protocols. This topic is discussed in the PACSystems RX3i PROFINET IO Controller User Manual, GFK-2571F or later. LAN2 and LAN3 each support a pair of RJ45 connectors. In this way, network devices on the same LAN, but operating at different data rates may be connected to a suitably configured port. To establish Ethernet communications between the PME programming and configuration software and the CPU, you first need to know the target IP address.
