1.1功能概述 
1.1 Function Overview 

GCAN-PLC-320/321/322系列是集成总线控制功能并支持双网口网络交换的可编程逻辑控制器（PLC）。其不仅具有外观简约、高性价比的特点，还可以方便的连接入CAN总线系统及Modbus系统等，并可通过插片式模块进行扩展。 
The GCAN-PLC-320/321/322 series is a programmable logic controller (PLC) that integrates bus control functionality and supports dual port network switching. It not only has the characteristics of simple appearance and high cost-effectiveness, but also can be easily connected to CAN bus systems and Modbus systems, and can be expanded through plug-in modules. 

GCAN-PLC-320/321/322产品由一个可编程的主控模块（GCAN-PLC-320/321/322等）、若干GC系列IO模块（GC-1008、GC-3804等）以及一个终端电阻模块（GC-0001）组成。GCAN-PLC-320/321/322主控模块可连接所有的GC系列IO模块，用户可根据现场实际需求自行选择扩展IO模块，IO模块数量最多可扩展16个，主控模块可根据插入IO模块的前后位置自动分配地址，实现自动组态，用户无需在PC上创建组态界面及设置参数。 
The GCAN-PLC-320/321/322 product consists of a programmable main control module (GCAN-PLC-320/321/322, etc.), several GC series IO modules (GC-1008, GC-3804, etc.), and a terminal resistor module (GC-0001). The GCAN-PLC-320/321/322 main control module can connect all GC series IO modules, and users can choose to expand IO modules according to their actual needs on site. The maximum number of IO modules can be expanded by 16. The main control module can automatically allocate addresses according to the front and rear positions of the inserted IO modules, achieving automatic grouping. Users do not need to create a configuration interface or set parameters on the PC. 

GCAN-PLC-320/321/322可使用OpenPCS软件对其编程，也可使用Codesys V3.5 SP16及以上版本软件对其编程。软件支持符合IEC-61131-3标准中规定的五种标准编程语言，这使得程序的可移植性和复用性很强，而且软件还具有多种调试功能（断点、单步等），调试程序更加方便。 
GCAN-PLC-320/321/322 can be programmed using OpenPCS software or Codesys V3.5 SP16 and above software. The software supports five standard programming languages specified in the IEC-61131-3 standard, which makes the program highly portable and reusable. Additionally, the software has multiple debugging functions (breakpoints, single steps, etc.), making debugging programs more convenient. 

GCAN-PLC-320/321/322不仅可完成各种数字/模拟量的输入/输出，还集成了多种常用的工业现场总线，如：CAN总线（GCAN-PLC-321/322支持）、RS485总线、RS232总线、以太网总线，并支持常见的通信协议如：CANopen（GCAN-PLC-321/22支持）、Modbus RTU、Modbus TCP等。 
GCAN-PLC-320/321/322 not only can complete various digital/analog input/output, but also integrates multiple commonly used industrial field buses, such as CAN bus (supported by GCAN-PLC-321/322), RS485 bus, RS232 bus, Ethernet bus, and supports common communication protocols such as CANopen (supported by GCAN-PLC-321/22), Modbus RTU, Modbus TCP, etc. 

GC系列IO模块包括：开关量输入及输出模块、模拟量输入及输出模块、脉冲输入及输出模块等。详细选型列表请参阅本手册第7章。 
The GC series IO modules include switch input and output modules, analog input and output modules, pulse input and output modules, etc. Please refer to Chapter 7 of this manual for a detailed selection list.
