摘　　要：为减少硬件模块的重复开发,在保留原DCS软硬件系统架构不变的基础上,在以太网通信接口模块硬件上虚拟不同的I/O模块。虚拟I/O模块与硬点I/O模块具有一致的输入、输出及参数属性,且组态方式和产物格式一致。同一以太网通信模块上可在不同的虚拟I/O槽位上配置不同的虚拟I/O模块,如Modbus TCP虚拟I/O模块和GOOSE虚拟I/O模块,进而在同一硬件实现不同的通信功能。虚拟I/O模块的使用一方面减少了DCS系统硬件模块的种类,简化备品备件,另一方面也提高了通信扩展的灵活性和便利性。In order to reduce the repeated development of hardware modules,on the basis of retaining the original DCS software and hardware system architecture,different I/O modules are virtualized on the hardware of the ethernet communication interface modules.The virtual I/O module and the hard point I/O module have the same input,output,and parameter attributes,and the configuration mode and product format are the same.Different virtual I/O modules,such as Modbus TCP virtual I/O modules and GOOSE virtual I/O modules,can be configured on different virtual I/O slots on the same ethernet communication module,so as to implement different communication functions on the same hardware.The use of virtual I/O modules,on the one hand,reduces the types of hardware modules of the DCS system and simplifies spare parts.On the other hand,it also improves the flexibility and convenience of communication expansion.
