ABB P4LQA HENF209736R0003是一款1端口以太网适配器，支持多种通信协议，包括PROFINET IO、EtherNet/IP和Modbus TCP。它可以通过参数设置来选择所需的协议，支持PROFINET IO DP-V1通信。FENA-01/-11模块可以用于PROFIdrive配置文件或ABB变频器配置文件。此外，这款适配器还提供两种透明模式——分别针对16位和32位的字。作为EtherNet/IP服务器，FENA以太网适配器支持ODVA AC/DC Drive、ABB变频器和Transparent配置文件。对于不同的配置文件，适配器模块既支持对一类的每个属性分别进行设置的显式报文，也支持使用输入和输出实例的隐式报文。同时，Modbus TCP也支持通用的读/写单寄存器功能代码和多寄存器功能代码。

It is a 1-port Ethernet adapter that supports multiple communication protocols, including PROFINET IO, EtherNet/IP, and Modbus TCP. It can select the required protocol through parameter settings and supports PROFINET IO DP-V1 communication. The FENA-01/-11 module can be used for PROFIdrive configuration files or ABB frequency converter configuration files. In addition, this adapter also offers two transparent modes - for 16 bit and 32 bit words, respectively. As an EtherNet/IP server, the FENA Ethernet adapter supports ODVA AC/DC Drive, ABB frequency converter, and Transparent configuration files. For different configuration files, the adapter module supports both explicit messages that set each attribute of a class separately, and implicit messages that use input and output instances. Meanwhile, Modbus TCP also supports universal read/write single register function codes and multi register function codes.
