【博图TIA-Api】通过Excel自动新建文件夹和导入FB块

本文主要是介绍【博图TIA-Api】通过Excel自动新建文件夹和导入FB块，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

说明

续上一篇文章，这次是根据Excel表格在程序内新建文件夹和导入FB块。

思路

• 调用TIA的Api接口
• 实现方式为C#的“Windows 窗体应用(.NET Framework)，(默认PC已经装了Visual Studio)
• 文件夹名和FB块名存在Excel文件中，导入时需要选择文档
• 西门子子接口使用文档(中文的) 点击链接进入
• 注意如果文件夹已经存在就不能新建。
• FB块如果存在可以覆盖，方便快速修改。

准备

该文章已提过的准备事项就不再重复，只提及未重复的。链接: 【博图TIA-Api】通过Excel自动快速导入IO变量

获取Excel表格内文件名和FB块名等信息

上述链接可查看。

新建文件夹部分

筛分获取的文件夹数据，去掉重复内容

注意这里并不是去除程序内的重复文件夹，只是对Excel文件内读取的文件名去重。

public static void CreatNewFileGroup(string filepath, PlcSoftware plcsoftware, bool enabled)
{if (!enabled){return;}string[] result = new string[300];int i;int j = 1;bool Mid;string[,] strings = new string[1000, 15];strings = ManualImport.ManualReadExcelFile(filepath);//筛选出所有组名for (i = 1; strings[i, 1] != null; i++){Mid = false;//有重复的就不加入数组foreach (string strmid in result){if (strmid == strings[i, 1]){Mid = true;break;}}//没重复的添加进数组if (!Mid){result[j] = strings[i, 1];j++;}Mid = true;}//调用文件夹新建程序for (i = 1; result[i] != null; i++){ManualImport.CreateBlockGroup(plcsoftware, result[i]);}
}

创建文件夹

注意由于PLC内文件夹可能会有很多层级，我这里默认是三个层级，如果层级更多可以按照这样写。[注]

public static void CreateBlockGroup(PlcSoftware plcsoftware, string FileName)
{//测试用string[] strings = new string[20];int i, j;PlcBlockGroup userblock1, userblock2, userblock3, userblock4;PlcBlockGroup finallyblock;PlcBlockSystemGroup systemGroup = plcsoftware.BlockGroup;//测试用于查看块组名字--程序块#region 已屏蔽//string NameBlock =systemGroup.Name;#endregion//获取程序块下三个大文件夹，第0个是程序块文件夹最下面的一个，也就是需要的#region 获取 根目录i = 0;j = 0;foreach (PlcBlockGroup blockgroup in systemGroup.Groups){strings[i] = blockgroup.Name;if (strings[i] == "根目录名"){j = i;}i = i + 1;}userblock1 = systemGroup.Groups[j];#endregion#region 获取 层级一i = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock1.Groups){strings[i] = blockgroup.Name;if (strings[i] == "层级一名"){j = i;}i = i + 1;}userblock2 = userblock1.Groups[j];#endregion#region 获取 层级二i = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock2.Groups){strings[i] = blockgroup.Name;if (strings[i] == "层级二名"){j = i;}i = i + 1;}userblock3 = userblock2.Groups[j];#endregion#region 获取 层级三i = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock3.Groups){strings[i] = blockgroup.Name;if (strings[i] == "层级三名"){j = i;}i = i + 1;}userblock4 = userblock3.Groups[j];#endregionfinallyblock = userblock4;//确保文件夹不重复j = 0;foreach (PlcBlockGroup blockgroup in finallyblock.Groups){strings[i] = blockgroup.Name;if (strings[i] == FileName){//代表文件夹已经存在j = 100;}i = i + 1;}if (j == 100){return;}else{PlcBlockUserGroupComposition groupComposition = finallyblock.Groups;//新建文件夹名PlcBlockUserGroup myCreatedGroup = groupComposition.Create(FileName);}}

导入FB块

导出FB块的xml文件

注意一般这个功能适合哪些重复的FB块导入，比如说一些标准块。

导出FB块的xml文件可以从版本控制接口导出。

查找需要放置的文件夹

这里就以之前的三个层级位置举例。
这里需要返回需要的文件夹变量PlcBlockGroup

 public static PlcBlockGroup FindMovementFB(string BlockGroupName, PlcSoftware plcsoftware){string[] strings = new string[20];int i, j;PlcBlockGroup userblock1, userblock2, userblock3, userblock4, userblock5;PlcBlockGroup finallyblock;PlcBlockSystemGroup systemGroup = plcsoftware.BlockGroup;//测试用于查看块组名字--程序块#region 已屏蔽//string NameBlock =systemGroup.Name;#endregion//获取程序块下三个大文件夹，第0个是程序块文件夹最下面的一个，也就是需要的OEM#region 获取 根目录i = 0;j = 0;foreach (PlcBlockGroup blockgroup in systemGroup.Groups){strings[i] = blockgroup.Name;if (strings[i] == "根目录名"){j = i;}i = i + 1;}userblock1 = systemGroup.Groups[j];#endregion#region 获取 层级一i = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock1.Groups){strings[i] = blockgroup.Name;if (strings[i] == "层级一名"){j = i;}i = i + 1;}userblock2 = userblock1.Groups[j];#endregion#region 获取 层级二i = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock2.Groups){strings[i] = blockgroup.Name;if (strings[i] == "层级二名"){j = i;}i = i + 1;}userblock3 = userblock2.Groups[j];#endregion#region 获取 层级三i = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock3.Groups){strings[i] = blockgroup.Name;if (strings[i] == "层级三名"){j = i;}i = i + 1;}userblock4 = userblock3.Groups[j];#endregioni = 0;j = 0;foreach (PlcBlockGroup blockgroup in userblock4.Groups){strings[i] = blockgroup.Name;if (strings[i] == BlockGroupName){j = i;}i = i + 1;if (i >= 30){break;}}userblock5 = userblock4.Groups[j];#region 获取需要放置的文件夹#endregionfinallyblock = userblock5;//返回需要的PlcBlockGroupreturn finallyblock;}

导入块

这里的xml文件默认放在改程序的根目录。

public static void InputMovementFB(string filepath, string Xmlpath, PlcSoftware plcsoftware, bool enabled)
{if (!enabled){return;}string[] result = new string[300];int i;int j = 1;bool Mid;string[,] strings = new string[1000, 18];//读取Excel表格内容strings = ManualImport.ManualReadExcelFile(filepath);XmlDocument xmlDoc = new XmlDocument();//加载xml文件，文件xmlDoc.Load(Xmlpath);bool mid1, mid2, mid3;for (i = 1; strings[i, 1] != null; i++){#region 修改FB块名字//查找要修改的节点XmlNode Name = xmlDoc.SelectSingleNode("Document/SW.Blocks.FB/AttributeList");//取出所有的子节点XmlNodeList xnl = Name.ChildNodes;mid1 = false;mid2 = false;//取出PLC变量表名字foreach (XmlNode xmlNode in xnl){//将节点转换一下类型XmlElement xmlElement = (XmlElement)xmlNode;//判断该子节点是否是要查找的节点if (xmlElement.Name == "Name"){//设置新值xmlElement.InnerText = "NO" + strings[i,2]+"MB"+ strings[i,5]+"_"+ strings[i,3];mid1 = true;}//判断该子节点是否是要查找的节点if (xmlElement.Name == "Number"){                        //设置新值xmlElement.InnerText = Convert.ToString(600+(Convert.ToInt32(strings[i, 2])-1)*20+Convert.ToInt32(strings[i, 5]));mid2 = true;}if (mid1 && mid2){break;}}#endregion//保存修改的Xml文件内容xmlDoc.Save(Xmlpath);FindMovementFB(strings[i, 1], plcsoftware).Blocks.Import(new FileInfo(Xmlpath), ImportOptions.Override); ;}}

注意这里修改的xml文件位置在此处
