OMNI Flow Computer

• 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.
