  • Fixed an issue where reads could starve writes when communicating to multiple devices in the same channel.



  • Removed non-inclusive terms out of respect for users of our software.



  • Fixed an issue where a late-arriving Opcode 135 response could get applied to the wrong point.       



  • Added a pointer rollback to retrieve lost data from a device. If the device’s cache pointer is valid, rollback will be applied to cache pointer, otherwise the rollback will be applied to the current device pointer.



  • Corrected EFM exporter output for Meter Type and Calculation Method using polled device settings. 



  • Problem behoben, bei dem die Kommunikation unmittelbar nach der Initiierung der Kommunikation mit dem Gerät fehlschlagen konnte.



  • Aktualisierung der Parametergröße für Parameter #0(Geräte-Tag) in der Adresstabelle von Punkttyp 177 von 10 auf 40 Byte.


  • Neue zusätzliche Optionen für die Zeitsynchronisierung
    • Zeitsynchronisierung nur zulassen, wenn der Unterschied zwischen Geräte- und Systemzeit einen bestimmten Schwellenwert überschreitet.
    • Zeitsynchronisierung nach EFM-Abruf durchführen.



  • Deaktivierung der Zeitsynchronisierung bei deaktivierter Datensammlung.
  • Fehlende Gasattributzuordnungen für H2, HE, CO und AR hinzugefügt.
  • Punkttypen 93, 94 für Gasmodelle aktiviert.



  • Messgeräte werden nun in der Projekthierarchiedarstellung angezeigt, um Sichtbarkeit und Bearbeitung zu verbessern.
  • Das Problem, dass EFM-Daten für avg_c8, avg_c9 und avg_c10 nicht in eine CSV-Datei exportiert wurden, wurde behoben.
  • Die Spaltenzuordnung von EFM-Daten für n-Pentan und neo-Pentan wurde korrigiert.



  • Resolved a Time Sync issue where, if no reads are active; only the first four (4) devices successfully synchronize.
  • Enhanced the driver to allow UDP tags to use the correct data type set (not default). This allows the data type of these tags to be manually modified.



  • Added support for Advanced Statistics Tags, including _CommFailures, _ErrorResponses, and more.
  • The driver now includes the #n syntax when auto-generating tags for similarly named point types in point type tables to avoid duplicate tag names. This may change the default name for some auto-generated tags from previous versions.
  • Changed the alarm state from OFF to On for string events.
  • Resolved an issue where attempting to read a tag from a non-responsive device could falsely cause a timeout when reading the next tag on a different device.
  • Resolved an issue where reading multiple tags in the same point type logical could result in two separate read requests rather than one.
  • Corrected mappings for liquid temperature high and low limits to EFM exports.



  • The driver no longer performs a time synchronization operation on startup when the Time Sync Method is Absolute.
  • Added support for reading and writing to user tables using Opcodes 10 and 11.
  • Added the ability to ignore extra bytes received on the wire that are not part of the ROC communications. These bytes are sometimes added by radio modems and other networked equipment.
  • Enhanced the drivers to support Opcode 180. Enabled per device, this allows the driver to read multiple TLP and UDPs per read request.



  • Spaces are no longer allowed in liquid and gas meter names.



  • Fixed a server deadlock that could occur when launching a client that had 100,000 or more tags configured for a device.



  • Removed the potential for a hang when a client accesses tags containing UDP point types.



  • 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 the new 809L and 827L models with support for Liquid EFM and export to Flow-Cal V7. The new models support EFM configuration, hourly history, daily history, batch, alarms, and events upload.
  • Added new ROC800L point types. This required the addition of a new "T_LONG" data type.
  • Fixed an issue where Default data type was always returned for UDP tags, even if the UDP data type was known by the server. This could cause writes that occurred before an initial read of the UDP tag to fail.
  • Fixed an issue where Gas EFM data would not upload if the meter being uploaded was preceded by a segment containing no TLP mappings.


  • Enhanced the Fisher ROC Plus Serial Driver to support User-Defined Points. This includes support for Dynamic Tag creation as well as Online and Offline Automatic Tag Generation.
  • Added support for following point ranges:
    • Lower UDP range: Points 60 through 78
    • Upper UDP range: Points 196 through 254
  • Increased the maximum number of supported channels to 1024.
  • Resolved an issue where an EFM history upload from a device with five or less points configured in a history segment would fail due to framing error.
  • Added support for point type 177, Wireless HART.


  • Fixed an issue where automatic tag generation would not create Point Types 101 through 109.
  • Fixed an issue where automatic tag generation created point types with incorrect Logical Addresses.
  • Added support for Point Types 98-x.53 through 98-x.60.
  • Added a Set/Clear indication to the beginning of the alarm strings exported via the EFM Exporter Plug-In.


Improved the driver's EFM data collection performance and efficiency when intermittent communication errors occur with the connection to the EFM data source. The optimizations are automatically handled in the driver: no project configuration changes were required in the driver UI.



  • Added Electronic Flow Measurement (EFM) Support
  • Updated the driver with the new Connection Sharing feature.
  • Enhanced the driver to consume the extra bytes that may be received following a valid frame.



Added support for the use of legacy tag names as part of Automatic Tag Generation. This enhancement was made to resolve a change introduced in the 5.8 release where tag formats created via Automatic Tag Generation were different than previous versions. This tag format issue only affects users who upgraded to version 5.8 and triggered tag regeneration.

For new installations of Fisher ROC Plus driver (server version V5.9 and up), the default setting for this checkbox is 'checked' so legacy tag names are used.


Added support for Channel Serialization, Inter-Device Delay, and RTS Line Control. Updated the Operator Identification tab in Device Properties to be more consistent with ROCLINK configuration software. Consolidated Tag Import Settings under a single tab in Device Properties.


  • Increased the channel limit to 256.
  • Fixed an issue caused when a controller responded with a data length greater than the data length supported by the protocol. This would cause a buffer overflow which could cause the driver to stop working. Added verification of data length returned by controller.


  • Increased the maximum devices per channel from 32 to 255.


  • Fixed an issue with unhandled exception in the driver.
