6.4.321.0

2017/12/13

Enhanced to treat table validation errors as recoverable and continue table validation attempts until successful.

6.3.273.0

2017/9/27

修復了以下問題：在未設置觸發(fā)器條件的情況下將進行初始日志記錄。
修復了以下問題：使用 DataChange 觸發(fā)器記錄項目導致使用服務器時間戳。
增強了存儲和轉(zhuǎn)發(fā)存儲目錄驗證。

6.2

2017/6/8

Fixed an issue where DataLogger used the Dynaset open method in some cases rather than Snapshot when a MySQL DSN was used. MySQL does not support Dynasets.

6.1.601.0

2017/4/4

The timestamp logged to the database will now reflect the time of the last data change.
Resolved validation errors that caused the runtime to fail to load JSON and XML project files, which resulted in an 'Invalid Name' event log message.
Fixed an issue where fields other than TIMESTAMP would give a SQL "Datetime field overflow" message when their data type is set to DATETIME.
Fixed an issue where a read-only user could modify log groups.

6.0.2107.0

2016/11/15

Log item timestamp now reflects the item log time rather than the last data change time.

5.21.114.0

2017/3/20

Updated log item timestamps to always reflect the item log time rather than the last data change.

5.21.112.0

2016/8/16

Fixed a situation where initial values were not logged.
Fixed an issue where all log groups shared the same VARCHAR mapping checkbox state.
Changed behavior of the "Log on Static Interval" trigger option to log the current timestamp rather than the timestamp of the last data change. This change restored the behavior that existed prior to the 5.20 release.

5.20.396.0

2016/5/3

Added support for mapping Numeric ID to VARCHAR instead of NUMERIC.
Updated the timestamp logged to the database to reflect the time of the last data change when using “Log on Data Change.”

5.19.467.0

2015/10/20

Added an error string for “Too many tags to log in wide column format” to message log and documentation.
Corrected an issue where NULL quality could be written.
Resolved an issue where a trigger interval of greater than 24 days could cause the trigger to appear to be constantly on, causing excessive writes to the database.
Resolved an issue that could cause data corruption when writing large strings or arrays.

5.18.662.0

2015/6/23

Removed the ability to pick a data type for log items. The type was not used.
Fixed an issue where enabling a DataLogger log group after reinitializing the server did not correctly start the log group.

5.15.585.0

2014/7/22

Reorganized the Triggers dialog to be more intuitive. The start/stop logging options were moved to the Absolute and Expression trigger type pages. The Log on Static Interval and Log on Data Change logging options were moved to a new Logging Conditions page.

Added a new trigger condition that allows a snapshot to be taken of a log group's current tag values when a monitored item changes. A deadband can be applied to the monitored item to control how often a snapshot occurs.

Fixed an issue where enabling a log group could cause false triggers in some trigger expressions that included server tag data. In these cases, the tags failed to get an update before the trigger expression was checked, which caused the check to return true incorrectly.

Fixed an issue where a negative value was shown for the log group's Update Rate (located on the Data Map tab) if the Update Rate was greater than 24 days.

5.14.491.0

2014/2/18

Added support for store and forward. Log groups can now store data locally to disk when connectivity to the SQL server is lost, and then forward the data when connectivity returns.

Fixed an issue where performing a CSV export would disable the Apply Changes button without applying the changes to the Runtime. Now, performing a CSV export causes the changes to be applied and disables the Apply Changes button.

Fixed deadlock that could occur if Link Tags were linked to DataLogger System Tags. The deadlock occurred when starting a log group.

5.12.142.0

2013/8/5

Resolved a DataLogger issue introduced in KEPServerEX version 5.12.140.0 where values for columns associated with the first log item in the Server Item List were incorrectly logged as NULL. This issue affects customers who upgraded to version 5.12.140.0 from an earlier server/plug-in version and use the Wide Table Format to log data.

5.9.170

2012/6/26

Added the new "Item data set to good quality" Event Expression trigger to the Start and Stop condition pick lists.

什么是高級插件？

KEPServerEX 不僅是 OPC 服務器，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。
