Wonderware Historian Servers 操作

1、概述

工控软件Wonderware System Platform带有Historian实时归档数据库，采用SQL Server+本地文件形式管理和存储归档数据。数据的元数据（包括标签名、说明、采样频率等）存储在SQL Server的Runtime库中，归档的结果数据存储在本地。

2、Historian架构

Historian架构图如下：

3、Microsoft SQL Server Management Studio

数据库的分析等，可以使用Microsoft SQL Server Management Studio直接操作，主要是数据在视图中。可以使用标准SQL语法，但需要注意相关约束。

4、插入和查询语法示例

INSERT INSQL.Runtime.dbo.AnalogHistory (DateTime, TagName, Value,
QualityDetail)
VALUES ('1999-11-11 16:05:10', 'NonIOTag1', 56, 192)

INSERT INTO INSQL.Runtime.dbo.StringHistory (DateTime, TagName, Value,
wwTimeZone, wwVersion)
VALUES ('1999-11-11 16:05:10', 'IOstring1', 'Batch 10', 'Eastern Standard
Time', 'latest')

INSERT v_History (TagName, QualityDetail, Value, DateTime)Importing, Inserting, or Updating History Data Wonderware Historian Administration Guide
Version 17.3.100 163
VALUES ('NonIOtag1', 192, 56, '1999-11-11 16:05:10')

INSERT INTO v_History (TagName, DateTime, Value, QualityDetail)
SELECT 'ManualReactTemp', DateTime, 32 + Value * 9 / 5, 192 FROM
v_AnalogHistory
WHERE TagName = 'ReactTemp'
AND DateTime >= dateadd(mi, -50, getdate())
AND DateTime < dateadd(mi, -10, getdate())
AND wwRetrievalMode = 'Delta'

DECLARE @Value float
DECLARE @DateTime DateTime
SET @Value = 1.2345
SET @DateTime = DateAdd(Minute, -10, GetDate())
INSERT v_History (DateTime, TagName, Value, QualityDetail)
VALUES (@DateTime, 'NonIOTag1', @Value, 192)

5、编程开发

在本机连接和操作数据，C#参考代码段如下：

private string SqlServerConnString = "Persist Security Info=False;Integrated Security=true;Initial Catalog=runtime;server=(local)";

using (SqlConnection conn = new SqlConnection())
{
String sql = "SELECT TagName,Description,AcquisitionType,ItemName,TagType FROM _Tag";
conn.ConnectionString = SqlServerConnString;
conn.Open();
SqlCommand cmd_query = new SqlCommand(sql, conn);
cmd_query.ExecuteNonQuery();
using (SqlDataReader reader = cmd_query.ExecuteReader())
{
while (reader.Read())
{
String TagName = reader["TagName"].ToString();
String Description = reader["Description"].ToString();
String AcquisitionType = reader["AcquisitionType"].ToString();
String ItemName = reader["ItemName"].ToString();
String TagType = reader["TagType"].ToString();

System.Console.WriteLine($"{TagName},{Description},{AcquisitionType},{ItemName},{TagType}");
}
}
}

其他语言代码可以参考上面的进行修改。

Historian默认是仅允许本机访问，如果需要提供远程访问，需要修改SQL Server的相关配置
