S7.Net documentation S7.Net 文档 How to download s7.Net 如何下载s7.Net The official repository is on GitHub ( /killnine/s7netplus) , you can also download the library directly from NuGet (/packages/S7netplus/). 官方存储库位于 GitHub （/killnine/s7netplus ）上，您也可以直接从 NuGet （/packages/S7netplus/ ）下载该库。 What is S7.Net 什么是S7.Net S7.Net is a plc driver that works only with Siemens PLC and only with Ethernet connection. This means that your plc must have a Profinet CPU or a profinet external card (CPxxx card). S7.Net is written entirely in C#, so you can debug it easily without having to go through native dlls. S7.Net 是一个plc 驱动程序，仅适用于Siemens PLC 和以太网连接。 这意味着 您的PLC 必须具有Profinet CPU 或Profinet 外部卡（CPxxx 卡）。 S7.Net 完全用C ＃编写，因此您无需通过本机dll 即可轻松调试它。 Supported PLC 支持的PLC S7.Net is compatible with S7-200, S7-300, S7-400, S7-1200, S7-1500. S7.Net 与S7-200，S7-300，S7-400 ，S7-1200 和S7-1500 兼容。 Getting started with S7.Net S7.Net 入门 To get started with S7.Net you have to download and include the S7.Net.dll in your project. You can do this by downloading the NuGet package, or by downloading the sources and compile them. 要开始使用S7.Net，您必须下载S7.Net.dll 并将其包含在您的项目中。 你可以这样做 通过下载NuGet 软件包，或通过下载源代码并进行编译。 Create a PLC instance, connect and disconnect 创建一个PLC 实例，连接和断 开连接 To create an instance of the driver you need to use this constructor: 要创建驱动程序的实例，您需要使用以下构造函数： public Plc(CpuType cpu, string ip, Int16 rack, Int16 slot) Cpu: this specify what CPU you are connecting to. The supported CPU are: public enum CpuType { S7200 = 0, S7300 = 10, S7400 = 20, S71200 = 30, S71500 = 40, } Ip: this contains the IP address of the CPU of external Ethernet card 包含外部以太网卡CPU 的IP 地址 Rack: this contains the rack of the plc, tha
