适用于 KEPServerEX 的 OMNI Flow Computer 驱动程序能够与 OMNI 3000 和 6000 系列流量计算机通信。它支持实时通信以及对历史数据的电子式流量测量 (EFM)。对于仅实时通信,可单独购买 OMNI Flow Computer 驱动或通过购买 Oil and Gas Suite 获得。对于需要 EFM 和实时通信的应用程序,可通过购买 EFM Suite 获得 OMNI Flow Computer 驱动。EFM 功能包括将 EFM 历史记录、警报和事件数据调度和导出至行业标准和自定义格式。

  • 增加了 Modicon 模式支持。



  • 改进了清除缓存逻辑,以允许在应用后检索所有条目。


  • 增加了更多有关时间同步的选项:
    • 仅在设备时间与系统时间之差超过某个阈值时才允许时间同步。
    • 对 EFM 轮询执行时间同步。



  • 解决了 V6.0 版本中出现的以下问题:当运行环境重新初始化时,为每个设备重置驱动程序的 EFM 缓存。



  • 修复了重新初始化运行时会导致 EFM 缓存重置的问题。



  • 现在,仪表、映射和警报呈现在项目树状视图中,以改进可见性和编辑能力。
  • 现在,在项目树状视图中的映射对象上单击右键可找到映射的 CSV 导入/导出选项。
  • “恢复到默认值”映射现在位于“编辑”(Edit) |“连接”(Connectivity) 下;在项目树状视图中的映射对象上单击右键也可找到此选项。
  • 项目文件 (.opf) 现在同时保存液体和气体映射值,但一次仅显示一个。


  • 增加了对在 Modicon 模式下运行的设备的支持。



  • Enhanced the driver to cache the pointer file to disk so that it will not re-poll for data already collected on start-up.
  • Added support for scaling EFM values using the EFM Mapping in the GUI.
  • Updated the flow_time and meter_factor attributes to automatically apply scaling for legacy projects. These attributes were previously scaled but were not user-configurable.
  • Changed the header text in the history and batch mapping UI from "Gas Quality�? to "Gas Composition (Mole%)�? for gas devices and from "Mole % Composition�? to "Liquid Composition (Mole%)�? for liquid devices.



  • Added support for Liquid EFM. The driver now supports both Liquid EFM and Gas EFM models. The Liquid EFM model supports EFM configuration, hourly history, daily history, batch, alarms, and events upload. It also has the ability to configure and map OMNI archives.
  • Fixed an issue where flow time was not properly scaled. OMNI flow times are recorded in 500 millisecond ticks, and are now scaled to minutes for export to Flow-Cal and other formats.
  • Fixed an issue where alarm state values exported to Flow-Cal CFX V5 files were being decremented by one.
  • Added the archive number to the Event Log message that is displayed when the max size for an archive is set to zero in the device.
  • Fixed issues where the device error state was being improperly cleared after being set because of a DNR during an EFM history upload.
  • Fixed an issue where shared archive data would sometimes not be exported with a history record.


  • Improved the driver's EFM data collection performance and efficiency when intermittent communication errors are seen with the connection to the EFM data source. The optimizations are handled in the driver automatically and no project configuration changes are required in the driver UI.
  • Fixed a device password login problem that caused the driver to stop polling for data until the server runtime was restarted. The error was triggered when Ethernet Encapsulation devices returned "Exception Code 5" as a result of a login attempt with an incorrect password.



  • Updated the driver with the new Connection Sharing feature.
  • Updated the driver schema to improve EFM meter name validation.
  • Fixed an issue where the RTS and Inter-Request Delay settings were not being respected during the write portion of a Read/Modify/Write transaction.

    Note: A Read/Modify/Write transaction occurs when writing to a bit within a register.

  • Removed the ability of meter names to begin with an underscore, contain quotation marks or periods, or have leading or trailing whitespace.
  • EFM upload (data collection) architecture was enhanced to improve application scalability for projects containing a large number of EFM meters per poll grou



This new serial driver communicates with OMNI Flow Computers, which are primarily used in Oil & Gas applications. It supports real-time communications as well as Electronic Flow Measurement (EFM), where EFM data is collected and logged via the EFM Exporter Plug-In.
