1.1 Function Overview 

GCAN-8101 Modbus总线耦合器可以用于连接Modbus总线系统与分布式总线端子模块，这些端子模块可以通过模块化的方式进行扩展。一个完整的节点由一个总线耦合器、1-32个任意数量的端子模块以及一个终端端子模块组成。 
The GCAN-8101 Modbus bus coupler can be used to connect Modbus bus systems with distributed bus terminal modules, which can be expanded in a modular manner. A complete node consists of a bus coupler, 1-32 terminal modules of any number, and one terminal module. 

GCAN-8101总线耦合器通过GC-bus扩展技术，最多可连接32个输入/输出端子模块。 
The GCAN-8101 bus coupler can connect up to 32 input/output terminal modules through GC bus expansion technology. 

GCAN-8101 Modbus总线耦合器采用标准的Modbus总线协议，是一个标准的Modbus从站设备。支持modbus TCP与modbus RTU（485）。除此之外，通过网口还可以对固件进行升级，以满足客户的定制化需求。 
The GCAN-8101 Modbus bus coupler adopts the standard Modbus bus protocol and is a standard Modbus slave device. Supports Modbus TCP and Modbus RTU (485). In addition, firmware can be upgraded through the network port to meet customers' customized needs. 

GCAN-8101总线耦合器可连接所有的总线端子模块。就用户而言，模拟量输入/输出信号的处理方式与其它种类信号的处理方式没有任何区别。控制器过程映像区内的信息映射到modbus的4种寄存器中。 
The GCAN-8101 bus coupler can connect all bus terminal modules. As far as users are concerned, the processing method of analog input/output signals is no different from that of other types of signals. The information in the controller process image area is mapped to the four registers of Modbus. 

GCAN-8101总线耦合器支持自动组态，您无需在PC上设置组态。 
The GCAN-8101 bus coupler supports automatic configuration, so you don't need to configure it on your PC.
