下載試用

Advanced Tags 支持機器對機器 (M2M) 標簽鏈接、邏輯和數(shù)學(xué)函數(shù)功能應(yīng)用，適用于運營通信和分析。它可以鏈接兩個數(shù)據(jù)標簽，基于邏輯狀態(tài)設(shè)置觸發(fā)器并利用原始測量值計算新值。在 KEPServerEX 平臺執(zhí)行邏輯或數(shù)學(xué)運算，讓數(shù)據(jù)更加靠近數(shù)據(jù)源位置。

Advanced Tags 為用戶提供所需的工具以進行嚴密的運營分析。此分析需要工業(yè)控制應(yīng)用程序提供一組數(shù)據(jù)，這些數(shù)據(jù)需要某種形式的計算以識別缺陷并確定運營是否正確。Advanced Tags 提供六種簡單易用的預(yù)定義標簽以便在標簽級別執(zhí)行數(shù)學(xué)運算、邏輯或分析，幫助用戶提高在工業(yè)控制應(yīng)用程序中的決策質(zhì)量和效率。

包括六個預(yù)定義的鏈接、邏輯和數(shù)學(xué)標簽：
- 平均值標簽：計算一個標簽在既定時間內(nèi)的平均值。
- 復(fù)雜標簽：將不同數(shù)據(jù)類型的多個標簽組合為單一復(fù)雜項或結(jié)構(gòu)。
- 鏈接標簽：在不同協(xié)議之間鏈接數(shù)據(jù)。
- 最大值標簽：讀取并保留一個標簽在既定時間內(nèi)的最大值。
- 最小值標簽：讀取并保留一個標簽在既定時間內(nèi)的最小值。
- 衍生標簽：使用基本的腳本和標準邏輯與數(shù)學(xué)函數(shù)提供超過這些預(yù)定義標簽的計算。這些標簽?zāi)軌蚩刂票磉_式求值的頻率和條件，并讓用戶能夠?qū)⒏鼜?fù)雜的方程合并到應(yīng)用程序中。

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 的益處

1、成本：配合現(xiàn)有的微型 PLC、納米 PLC 和能力較弱的 PLC 使用，無需購買昂貴的 PLC 或 PACS。
2、時間：通過單一應(yīng)用程序配置鏈接、邏輯和數(shù)學(xué)函數(shù)，在所有硬件和軟件平臺中使用統(tǒng)一的方法。
3、性能：通過減少服務(wù)器與多個客戶端應(yīng)用程序之間的通信，降低網(wǎng)絡(luò)流量并提高帶寬。
4、可靠性：通過單一數(shù)據(jù)入口確保所有客戶端間數(shù)據(jù)一致。
5、知識：不需要特殊的 PLC 或 HMI 編程技能。
6、數(shù)據(jù)源：收集并操作各種應(yīng)用程序和設(shè)備中的數(shù)據(jù)。
7、項目修改：使用簡單明了的用戶界面輕松修改和配置全新的與現(xiàn)有的鏈接、邏輯和數(shù)學(xué)函數(shù)。

什么是高級插件？

KEPServerEX 不僅是 OPC 服務(wù)器，它還是一種適用于工業(yè)自動化和 IoT 的連接平臺。只需下載 KEPServerEX，然后從包含 150 多種設(shè)備驅(qū)動、客戶端驅(qū)動和高級插件的 Kepware 庫中選擇，以便適合您工業(yè)控制系統(tǒng)的獨特通信要求。

高級插件可擴展 KEPServerEX 連接平臺的功能。通過將設(shè)備中的原始數(shù)據(jù)轉(zhuǎn)換為其他形式，來提高數(shù)據(jù)實用性，并增強 KEPServerEX 的功能。

高級插件可以單獨進行許可或作為套件的組成部分進行許可，還可以隨著連接需求的發(fā)展按需進行許可。
