1. Function Introduction 

1.1功能概述 
1.1 Function Overview 

GCAN-205模块是集成1路标准以太网接口和1路标准CAN接口的ModbusTCP从站转CAN的协议转换模块。采用GCAN-205模块，用户可以轻松完成CAN总线网络和以太网网络的互连互通，进一步拓展CAN总线网络的范围。 
The GCAN-205 module is a protocol conversion module that integrates one standard Ethernet interface and one standard CAN interface from Modbus TCP slave station to CAN. By using the GCAN-205 module, users can easily achieve interconnection and intercommunication between CAN bus network and Ethernet network, further expanding the scope of CAN bus network. 

GCAN-205可以将以太网网络与CAN总线网络桥接，用户可以将此智能协议转换模块集成到自己的系统中，从而使本不具备相互通信能力的以太网网络与CAN总线快速具备通信能力，从而节省开发时间、降低开发成本、快速抢占市场先机。 
GCAN-205 can bridge the Ethernet network with the CAN bus network. Users can integrate this intelligent protocol conversion module into their own system, enabling the Ethernet network and CAN bus, which do not have mutual communication capabilities, to quickly have communication capabilities. This saves development time, reduces development costs, and quickly seizes market opportunities. 

GCAN-205模块现已被广泛应用于构建现场总线实验室、工业控制网络、智能小区监控等网络环境中。同时该设备具有体积小巧、即插即用等特点，且模块使用DIN导轨的安装方式，使其特别适用于工业现场或机柜中与其他设备配套使用。 
The GCAN-205 module has been widely used in building network environments such as fieldbus laboratories, industrial control networks, and intelligent community monitoring. At the same time, the device has the characteristics of small size, plug and play, and the module uses a DIN rail installation method, making it particularly suitable for industrial sites or cabinets to be used in conjunction with other devices. 

GCAN-205模块上已集成CAN接口电气隔离保护模块，使其避免由于瞬间过流/过压而对设备造成损坏，增强系统在恶劣环境中使用的可靠性。用户可以通过附带的“Gan205 EtherCanConfigv3”软件对GCAN-205模块进行配置。目前该配置软件仅支持Modbus TCP-CAN协议之间转换的配置，对于以太网端或CAN端的其他标准或自定义协议，暂时不支持用户自己对其配置，如需要，我公司可为用户提供任意协议之间的配置服务。 
The GCAN-205 module has integrated a CAN interface electrical isolation protection module, which prevents equipment damage caused by transient overcurrent/overvoltage and enhances the reliability of the system in harsh environments. Users can configure the GCAN-205 module through the included "Gan205 EtherCanConfigurav3" software. At present, this configuration software only supports the conversion configuration between Modbus TCP-CAN protocols. For other standard or custom protocols on the Ethernet or CAN side, it does not currently support users to configure them themselves. If necessary, our company can provide configuration services between any protocol for users.
