6.1.601.0

2017/4/4

Fixed an issue where the driver does not poll as expected from the update/poll rate.

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.

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。
