1.1功能概述 
1.1 Function Overview 

GCAN-8100 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，其中当扩展模块数量超过16片时，需额外增加一片IO供电扩展模块GC 8012以保证电源供应充足。GCAN-8100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-8100 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. When the number of expansion modules exceeds 16, an additional IO powered expansion module GC 8012 needs to be added to ensure sufficient power supply. The GCAN-8100 bus coupler can connect up to 32 input/output terminal modules through GC bus expansion technology. 

GCAN-8100 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。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-8100 Modbus bus coupler adopts the standard Modbus bus protocol and is a standard Modbus slave device. Supports Modbus TCP and Modbus RTU. In addition, firmware can be upgraded through the network port to meet customers' customized needs. 

GCAN-8100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个寄存器中。 
The GCAN-8100 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 four registers of Modbus. 

GCAN-8100总线耦合器支持自动组态，您无需在PC上设置组态。GCAN-8100总线耦合器通信参数可通过RS-232接口进行配置。 
The GCAN-8100 bus coupler supports automatic configuration, so you don't need to configure it on your PC. The communication parameters of the GCAN-8100 bus coupler can be configured through the RS-232 interface.
