      ODBC Client

      產(chǎn)品概覽

      ODBC Client 驅(qū)動(dòng)與 KEPServerEX 協(xié)同工作,可通過 Open DataBase Connectivity (ODBC) 提供對(duì)多個(gè) ODBC 數(shù)據(jù)源的單點(diǎn)訪問。ODBC 的目標(biāo)是能夠從任何應(yīng)用程序收集任何數(shù)據(jù),而無論處理數(shù)據(jù)的數(shù)據(jù)庫(kù)管理系統(tǒng) (DBMS) 為何。利用 OPC 的功能和速度,KEPServerEX 能夠向任何支持 OPC/DDE 的客戶端提供 ODBC 數(shù)據(jù),并通過強(qiáng)大的錯(cuò)誤處理能力確保數(shù)據(jù)完整性。

      發(fā)行說明

      6.1.601.0

      2017/4/4

      • Fixed a bug where MySQL stored procedures fail to execute.
      • Fixed an issue where millisecond resolution for DATETIME input types is lost when executing a stored procedure.

      5.21.114.0

      2017/3/20

      • Resolved an issue where MySQL stored procedures failed to execute. The issue was mistakenly introduced with the enhancements made in the 5.19 release.

      5.19.467.0

      2015/10/20

      • Added support for "Execute" statements within the Query access method.
      • Added an Execute tag for executing queries (e.g. Channel.Device.Execute).
      • Added the ability to enable or disable the query time interval. This allows users to exclusively trigger queries on demand via the device’s Execute tag.
      • Resolved an issue where a change in the query interval setting did not persist through shutdown and restart.
      • Removed duplicate messages that occurred in the event log when automatically generating tags.
      • Resolved issue with handling “money” and “smallmoney” data types as parameters to stored procedures in the stored procedure access methods.
      • Resolved an issue with the Update Tags button on the query and stored procedure access methods.
      • Resolved a configuration issue where a device prevents editing and reports that it is processing tags when no client references to the device exist.

      5.16.722.0

      2014/10/21

      • Increased the maximum number of channels from 100 to 256.
      • Updated the driver so that it will not force the access of tags added manually to be Read Only when the Set write access for imported database tags option is unchecked. This option only applies during automatic tag generation.
      • Updated automatic tag generation to force the internal tags that should be Read Only to be Read Only.

      5.14.491.0

      2014/2/18

      • Fixed an issue with incorrect Boolean conversion handling. Booleans can now be set and cleared properly.

      5.13.191.0

      2013/10/15

      • Fixed an issue where certain queries would result in bad quality for all tags in the device. The driver would post the "Unable to open recordset on device (Reason: Query timeout expired)" error message in the Event Log. This issue was due to an unnecessary query being used to count the number of items in the table.

      5.4.131.0

      2010/10/28

      • Fixed an issue with queries wherein the driver failed to read tags if the query included a UNION.
      • The EnableMiscellaneousQuerySettings registry setting was broken in 5x due to the separation of the Runtime and Configuration. The registry setting was removed, and the dialog page made visible to all users. A related wizard page was also added.

      5.3.118.0

      2010/6/9

      • Fixed an issue where the time stamps from reads of Oracle 10g failed because the returned string includes microsecond resolution. We now truncate the string to place it in a known format.
      • ODBC Client 驅(qū)動(dòng)能夠與支持標(biāo)準(zhǔn)“ODBC”或 MyODBC 數(shù)據(jù)源格式的任何應(yīng)用程序通信。
      • 需安裝 Microsoft Data Access Components (MDAC)。MDAC 包含若干核心組件,這些組件提供各種數(shù)據(jù)庫(kù)技術(shù),包括 ODBC 及其驅(qū)動(dòng)。

      什么是驅(qū)動(dòng)?

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

      驅(qū)動(dòng)是一種軟件組件,能夠使 KEPServerEX 滿足某個(gè)特定設(shè)備、系統(tǒng)或其他數(shù)據(jù)源的連接要求。此驅(qū)動(dòng)處理 KEPServerEX 與數(shù)據(jù)源進(jìn)行的所有專屬通信;客戶端接口處理通向監(jiān)控或控制設(shè)備的應(yīng)用程序的所有連接,包括支持的 OPC 連接、專屬連接和開放式標(biāo)準(zhǔn)連接。

      驅(qū)動(dòng)可以單獨(dú)或以套件形式獲得授權(quán)許可。隨著連接需求的發(fā)展,可以按需對(duì)其他驅(qū)動(dòng)進(jìn)行許可。
