  • [FEATURE] PQV-2713: PQDIF Observation Channel Mapper – support for skipping PQDIF channel import by mapping it to a empty string as PQView channel name.
  • [FIX] SUPPORT-1051, SUPPORT-1203. Revised channel name mapping to in SEL Data Handler address issue with harmonic wild card matching of higher order harmonics (e.g., 10, 11, 12, … )
  • [FIX] SUPPORT-1051: SEL Data Handler. EOI LDP values are now decoded as VAL instead of counts. The change allows for the import of Energy values stored in EOI LDPs.

  • [FIX] SEL Handler – Rework cbuffer get line to eat more of the line feed characters to handle when linux based files are handed to us(LF character only for new lines)
  • [FEATURE] More ui disk options were added to handle new disk mode imports. These are not serialized yet and will be reset upon DMS reload.
  • [FEATURE] Only filling out UI or specifying a good .ini file is now required for disk import mode. There is no need for SHO_R based files
  • [FEATURE] Disk mode no longer checks valid file names(i.e for iso8601 time base format or anything). The only requirement for LDP or CEV to import is: a good file, or the file ends with .ldp or .cev
  • [FEATURE] Disk/Event parser now gathers more data from file due to the removal of SHO_R dependent use in disk mode.
  • [FIX] PQVIEW SRP – Made iopath::DirectoryGetFiles not be case sensitive when scanning for search pattern when looking for files so users can have names like this: “CEV”, “cev”, “CEv”, “cEV”, etc.
  • [FEATURE] PQV-2721: IEC61850 DH – Enabled pool cancellation during the file processing. File download progress (10kb steps) reported in debug logs.
  • [FIX] SUPPORT-1051 – PQUBE connect function now scans for which pqube version to use by trying all the URLS that we know about instead of only being done in download function.
  • [FIX] SUPPORT-1051 – PQube will no longer log bad connect messages during connect phase if at LEAST ONE url works. The test however will show up in wireshark and its our auto finding mechanism at work.
  • [FIX] SUPPORT-1051 – PQube during connect now logs the proper url used instead of base url which will just appear to be a ip address for easier debugging.
  • [FIX] SUPPORT-1051 – More logging messages to help find issues.
  • [FIX] 61850 Handler – Hooked up cancel call back.
  • [FEATURE] PQV-2720: IEC61850 DH: Datalog reports background processing frequency preference added.
  • [FEATURE] PQV-2720: IEC61850 DH – Added support for exporting downloaded COMTRADE & PQDIF files to a local or network folder.
  • [FEATURE] PQV-2720: IEC61850 DH supports multiple PQDIF device folders separated by “;” separator. Download COMTRADE events flag set to FALSE prevents download regardless of RCDMade bypass setting.
  • [FIX] PQV-2715: Extra time sample handling improved for Metrum PQDIF files.
  • [FEATURE] PQV-2713: PQDIF Observation Mapper: Dynamic Mapping using ChannelParser implemented.
