Advanced Tags 支持机器对机器 (M2M) 标签链接、逻辑和数学函数功能应用，适用于运营通信和分析。它可以链接两个数据标签，基于逻辑状态设置触发器并利用原始测量值计算新值。在 KEPServerEX 平台执行逻辑或数学运算，让数据更加靠近数据源位置。

Advanced Tags 为用户提供所需的工具以进行严密的运营分析。此分析需要工业控制应用程序提供一组数据，这些数据需要某种形式的计算以识别缺陷并确定运营是否正确。Advanced Tags 提供六种简单易用的预定义标签以便在标签级别执行数学运算、逻辑或分析，帮助用户提高在工业控制应用程序中的决策质量和效率。

性能

  • 包括六个预定义的链接、逻辑和数学标签：
    • 平均值标签：计算一个标签在既定时间内的平均值。
    • 复杂标签：将不同数据类型的多个标签组合为单一复杂项或结构。
    • 链接标签：在不同协议之间链接数据。
    • 最大值标签：读取并保留一个标签在既定时间内的最大值。
    • 最小值标签：读取并保留一个标签在既定时间内的最小值。
    • 衍生标签：使用基本的脚本和标准逻辑与数学函数提供超过这些预定义标签的计算。这些标签能够控制表达式求值的频率和条件，并让用户能够将更复杂的方程合并到应用程序中。
  • 支持导入和导出逗号分隔变量 (CSV) 文件中的标签数据

6.1.601.0

2017/4/4

  • Server now replaces scan rate with minimum/maximum values rather than the default value if the scan rate imported from CSV is out of range.
  • Added support for using the NOT operator with derived tag string expressions.

5.21.112.0

2016/8/16

  • Fixed an issue, introduced in version 5.18, where the Input tag of a Linked tag could be incorrectly set to Active. This could cause unexpected and continuous polling of the Input tag.

5.19.467.0

2015/10/20

  • Resolved an issue where Advanced Tag mappings were not automatically generated in the Alias Map.

5.18.662.0

2015/6/23

  • Added support for bulk enable/disable of tags in the user interface.
  • Added the ability to undo a CSV import at the project level.
  • Quality is now set to bad with a configuration error when one or more of the tags the Advanced Tag references is invalid.
  • Quality is now set to bad with an out of service message when the user disables the referenced tag or one of its parent groups
  • Added support for reading Advanced Tags even when they are inactive. This allows an OPC client to add the Advanced Tag as inactive, perform a read, and get the most recent value.
  • Added a new quality keyword for Derived Tags. This allows derived expressions to use the tag quality as well as the tag value.
  • Enhanced the Link Tag to support a Link While True trigger mode. While in this mode, all changes to the input tag are written to the output tag at the given link rate.

5.17.495.0

2015/2/24

  • Removed repeated error messages when the plug-in fails to add a tag reference.
  • Fixed a memory leak that was caused by the plug-in failing to load a 'Complete' tag reference.

5.16.728.0

2014/11/18

  • Fixed an issue that was introduced in the 5.16.722.0 release where the initial value of a Derived Tag could be corrupted after a CSV import.

5.16.722.0

2014/10/21

  • Fixed an issue with Derived Tags where a device read from a client caused the Derived Tag's expression to execute.

5.15.585.0

2014/7/22

  • For the On Input Value Change (Ignore Initial Update) trigger, BAD quality is no longer considered a change of value and is ignored. This was done to ensure that the initial update is ignored whether it is good or bad quality.
  • Enhanced Derived Tags to allow string comparison using the equals (==) operator.
  • Fixed an issue where advanced tag trigger expressions that used string tags were not working properly.
 

5.14.491.0

2014/2/18

  • Enhanced Link Tags to have the new trigger mode option On Input Value Change (Ignore Initial Update). This mode is identical to the existing On Input Value Change option, except that the initial update does not cause the Link Tag to write to the output. This is useful when the initial value in the Input Tag is not required or meaningful.
  • Fixed a Link Tag issue where the output would not get updated if the input read returned too rapidly, as seen with internal or simulated tags.
  • Updated the XML schema to allow for tag descriptions up to 255 characters. Corrected the size of the address field to be 1024 characters.

ADVANCED TAGS 的益处

  • 1、成本：配合现有的微型 PLC、纳米 PLC 和能力较弱的 PLC 使用，无需购买昂贵的 PLC 或 PACS。
  • 2、时间：通过单一应用程序配置链接、逻辑和数学函数，在所有硬件和软件平台中使用统一的方法。
  • 3、性能：通过减少服务器与多个客户端应用程序之间的通信，降低网络流量并提高带宽。
  • 4、可靠性：通过单一数据入口确保所有客户端间数据一致。
  • 5、知识：不需要特殊的 PLC 或 HMI 编程技能。
  • 6、数据源：收集并操作各种应用程序和设备中的数据。
  • 7、项目修改：使用简单明了的用户界面轻松修改和配置全新的与现有的链接、逻辑和数学函数。
