提示

下载代码请复制以下命令到终端执行

为确保你提交的代码身份被 Gitee 正确识别,请执行以下命令完成配置

git config --global user.name userName 
git config --global user.email userEmail

初次使用 SSH 协议进行代码克隆、推送等操作时,需按下述提示完成 SSH 配置

1 生成 RSA 密钥

2 获取 RSA 公钥内容,并配置到 SSH公钥中

在 Gitee 上使用 SVN,请访问使用指南

使用 HTTPS 协议时,命令行会出现如下账号密码验证步骤。基于安全考虑,Gitee 建议配置并使用私人令牌替代登录密码进行克隆、推送等操作

简介

一款工业级轻量级组态软件 1.轻量级工控网关: 支持当前几种主要的工业协议如西门子的Profinet、AB的EtherNetIPs、施耐德的Modbus和OPC。采用类OPC接口网关。 2.数据采集、归档、预警及配置工具支持实时数据采集、历史数据归档、变量触发预警,并使用TagConfig工具简单的配置实现。 3.人机界面(设计时和运行时)。
