GlobalProperties是一个全局的数据，类似CoreData：

 public class GlobalProperties{public static Device Device { set; get; }public static Action<int, string> AddLog;public static SysAdmin CurrentAdmin;public static ModbusTCP Modbus { get; set; }///<summary>///确定大小端///</summary>public static DataFormat dataFormat = DataFormat.ABCD;/// <summary>///通过标签名称找对应的Variable对象///</summary>/// <param name="varName"></param>/// <returns></returns>private static Variable FindVariable(string varName){foreach (var item in Device.GroupList){var res = item.VarList.Find(c => c.VarName == varName);if (res != null){return res;}}return null;}public static bool CommonWrite(string varName, string varValue){var variable = FindVariable(varName);//第一步：先找到变量对象if (variable != null){// 第二步: 获取变量类型DataType dataType = (DataType)Enum.Parse(typeof(DataType), variable.DataType, true);// 第三步: 获取写入数据var result = MigrationLib.SetMigrationValue(varValue, dataType, variable.Scale.ToString(), variable.Offset.ToString());if (result.IsSuccess){// 第四步:写入数据switch (dataType){case DataType.Bool:                        return Modbus.PreSetSingleColls(variable.Start, Convert.ToBoolean(result.Content));/*return Modbus.PreSetSingleRegister(variable.Start, Convert.ToInt16(result.Content));*/case DataType.Short:return Modbus.PreSetSingleRegister(variable.Start, Convert.ToInt16(result.Content));case DataType.UShort:return Modbus.PreSetSingleRegister(variable.Start, Convert.ToUInt16(result.Content));case DataType.Int:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromInt(Convert.ToInt32(result.Content), dataFormat));case DataType.UInt:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromUInt(Convert.ToUInt32(result.Content), dataFormat));case DataType.Float:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromFloat(Convert.ToSingle(result.Content), dataFormat));case DataType.Double:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromDouble(Convert.ToDouble(result.Content), dataFormat));case DataType.Long:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromLong(Convert.ToInt64(result.Content), dataFormat));case DataType.ULong:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromULong(Convert.ToUInt64(result.Content), dataFormat));case DataType.String:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromString(result.Content, Encoding.ASCII));case DataType.ByteArray:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromHexString(result.Content));case DataType.HexString:return Modbus.PreSetMultiRegister(variable.Start, ByteArrayLib.GetByteArrayFromHexString(result.Content));default:break;}}}return false;}}

实体设备类，含有报警的检查和恢复触发：
