      OPC DA Client 驅(qū)動和 KEPServerEX 通信平臺提供了一種簡單且可靠的方式來將不同的第三方 OPC DA 服務(wù)器連接到您的客戶端應(yīng)用程序，包括 HMI、SCADA、Historian、MES、ERP 和無數(shù)自定義應(yīng)用程序。
      
                                                                				
      借助 OPC DA Client 驅(qū)動和 KEPServerEX，您可以通過單一服務(wù)器接口來管理操作，因此無需了解其他第三方服務(wù)器的不同差別。
      
                                                                				
      此驅(qū)動還可使 Oracle MES 和 MOC 用戶將 Kepware OPC 操作及其他所有第三方 OPC 操作引入您的業(yè)務(wù)應(yīng)用程序。

      6.3.273.0
      2017/9/27

        • 
								
      • 解決了以下問題：連續(xù)寫入相同值可能導(dǎo)致標(biāo)簽低質(zhì)。

      6.2
      2017/6/8
        
								
      • Fixed a crash issue when loading a project with an OPC DA Client using OPC DA 1.0.
        • 
							
      
							
      6.0.2107.0
      2016/11/15
        
								
      • Fixed issue where removing invalid items could result in a runtime failure.
        • 
							
      
							
      5.21.114.0
      2017/3/20
        
								
      • Enhanced the driver to support DA 3.0 browsing.
        • 
								
      • Resolved an issue where removing invalid items could result in a hang of the runtime.
        • 
							
      
							
      5.21.112.0
      2016/8/16
        
								
      • Refactored how the driver re-adds failed items. When items were continuously added and removed by the client where at least one of the items was invalid, it could lead to “Bad” quality of valid items and instability of the runtime.
        • 
							
      
							
      5.20.396.0
      2016/5/3
        
								
      • Enabled 64-bit data type support (LLong, QWord).
        • 
								
      • Added support for OPC Item Access Path using $ symbol for delimiters.
        • 
								
      • Enhanced the driver to allow OPC DA Read and Write methods (Asynchronous or Synchronous) based on the Update Mode of the OPC Group. Asynchronous Read and Write methods are the default and remain the optimal choice for most applications.
        • 
							
      
							
      5.19.467.0
      2015/10/20
        
								
      • Enhanced Automatic Tag Generation for a device object while one or more clients are actively connected.
        • 
								
      • Resolved an issue that could cause tag reads using ReadMaxAge to always read from cache.
        • 
								
      • Resolved an issue that could cause the client to receive a newly written value, then a stale cached value, before receiving the new value again. 
        • 
							
      
							
      5.16.722.0
      2014/10/21
        
								
      • Enhanced the OPC DA Client Driver so that it will now attempt to re-add failed items.
        • 
							
      
							
      5.15.588.0
      2014/9/23
      
							
        
								
      • Fixed an issue where the server could crash if an In-Process Server (which is a server that is a .dll not an .exe) threw an unhandled exception.
        • 
							
      
							
      
							
      5.15.585.0
      2014/7/22
      
							
        
								
      • Fixed an issue where AddGroup() calls would fail when CoInitializeEx () was called after CoInitializeSecurity ().
        • 
							
      
							
      
							
      5.11.250.0
      2013/3/5
      
							
      Resolved an issue where the driver would invalidate tags if the remote server did not provide a supported data type when the item was added to the server. The driver will now wait for the first update before invalidating unsupported data types.
      
							
      
							
      5.10.205
      2012/11/13
      
							
        
								
      • Previously, the driver would automatically filter out the data types that it could not resolve in a browser. It will now import these tags using the Default data type, and will also post a message to the Event Log.
        • 
							
      

							
        
								
      • Fixed an exception that would occur when invalidating tags while unloading the driver.
        • 
							
      

							
        
								
      • Fixed a reconnect issue where the shutdown sink flag was not cleared.
        • 
							
      

							
        
								
      • Fixed an issue where valid data change events were thrown away because the driver received data change events on items before they were fully added.
        • 
							
      
							
      
							
      5.9.170
      2012/6/26
      
							
      Fixed an issue in the Tag Import Browser where parent node tags would be imported even when only a child node was selected.
      
							
      
							
      5.7.84.0
      2011/10/24
      
							
        
								
      • Changed the default update rate from 50 milliseconds to 1000 milliseconds.
        • 
							
      
							
      
							
      5.6.122.0
      2011/7/25
      
							
        
								
      • Improved initial update performance when there is a mix of good and non-good data items from the underlying servers.
        • 
							
      
							
      
							
      5.5.94.0
      2011/2/18
      
							
        
								
      • Added support for two-dimensional arrays.
        • 
							
      
							
      
							
      5.4.131.0
      2010/10/28
      
							
        
								
      • When adding groups, the time bias is now properly initialized to zero. At this moment, this setting is not user-configurable.
        • 
								
      • Fixed an issue wherein the initial update was not passed on to client applications.
        • 
								
      • Removed the limit that prevented the creation of nested groups with depth greater than 8.
        • 
							
      
							
      
							
      5.3.118.0
      2010/6/9
      • The driver now reports a value, quality, and timestamp for invalid tags (tags that can't be added to the remote server). Previously we would keep attempting to read the tags, expecting an initial update. In the case that the tag is invalid, we won't receive an update, and should report the tag is Bad: Out of Service.
      • Improved performance of ATG.
							
      • The driver now removes all items from the underlying server when the DA Client's device is configured as disabled.
							
      • Fixed issue where the driver returned an invalid read value when an item did not receive an update from the DA Server. We now continue to process the read request until we have a valid return value.

      什么是驅(qū)動？
      
				
      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(dú)特通信要求。
      
				
      驅(qū)動是一種軟件組件，能夠使 KEPServerEX 滿足某個特定設(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，可以按需對其他驅(qū)動進(jìn)行許可。
