• Fixed an issue where writes would not be processed when multiple devices on a channel were configured to use a Register Requests/Packet setting greater than 1.

• Enhanced the driver to cache the pointer file to disk so that it will not re-poll for data already collected on server start-up.

• Fixed an issue that would cause the driver to re-poll records starting at sequence number one in the event that the sequence number is less than the archive capacity.

• Increased the ABB Totalflow Driver's maximum channel limit from 256 to 512.

• Increased the maximum number of supported channels from 100 to 256.

• Updated the driver to convert flow times reported by Totalflow devices in integer seconds to floating-point minutes. This makes flow times exported by the EFM Exporter for Totalflow meters consistent with other meter types.

• 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.

• Added DB1 as a supported Protocol Version of the driver to support G1 and early G2 Totalflow FCUs. The default setting for the driver is DB2 so users must edit Totalflow Settings to select DB1 for applicable devices in the server project.

• Fixed an issue where the Access Type for Characteristic tags was set to Read/Write when it should have been Read Only.

Initial release of the new driver with support for real-time and EFM communications. This release provides support for connectivity to Totalflow devices using the native DB2 protocol. The driver is a serial driver but supports Ethernet Encapsulation. The driver can be selected for installation independently or as part of the Oil & Gas Suite.
