6.4.321.0

2017/12/13

  • 不再为早于 v1.2 的所有 SSL/TLS 版本提供支持。此更改将影响在服务器端点 URL 中引用“HTTPS 安全性”的用户。

2017/4/4

  • 解决了以下问题:驱动程序不按照预期的更新/轮询速率轮询。

6.0.2206.0

2018/6/11

  • 修复了以下问题:由于在处理读取之后(而非之前)更新最近更新/轮询时间,驱动程序无法根据更新/轮询速率按预期轮询。

5.20.396.0

2016/5/3

  • Revised the Update Mode logic to allow more than one simultaneous subscription and prevent orphaned items and subscriptions.

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 where the “KeepAlive” message was no longer sent under adverse network conditions.
  • 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.

5.17.495.0

2015/2/24

  • Added support for 64-bit data types, including QWord, LLong, and arrays of these two types.

5.14.491.0

2014/2/18

  • Fixed issues that were encountered when browsing for items on certain devices (such as SIMOTION controllers). Tags with the default data type can now be added and the data type will be determined on its first read.
  • Added the ability to use the Max Items per Read setting when using Exception mode.
  • Improved browsing speed when not using the leaf filter.

5.13.191.0

2013/10/15

  • Fixed an issue where one tag with a bad address would cause all tags to have bad quality with certain XML-DA servers.
  • Added support for HTTP Authentication.
  • Added the item path to the tag address. The new syntax is <ItemPath><Delimiter><ItemName>. Tag import will read the item path; if it's not empty, it will build the tag address as displayed above. Users can specify the item path in Static Tags (which are manually created) in the same way. For a list of allowed item path delimiters, refer to the "Channel Setup" topic located in the help file.
  • Added the channel and device names to the "The item path <Channel>.<Device>.<ItemPath> is no longer available in the server address space" error message.
  • Added the item path (if it is not empty) to the "The item name <channel Name>.<Device Name>.<Item Path><delimiter><Item Name> is no longer available in the server address space" error message.

5.12.140.0

2013/6/18

  • Fixed faulty browsing logic where the driver would continue attempting to browse after an error was encountered. This could result in the driver being stuck in a loop while browsing.
  • Corrected a failure to import tags from servers that do not return the item name in the GetProperties response.
  • Fixed a defect where if the target XML-DA server returned OPC quality for an item, the driver would set the tag quality to Good during a subscription poll refresh.

5.11.250.0

2013/3/5

Initial release of a new driver used to connect to Third Party OPC XML-DA Servers.
