Below are five list containing the latest additions and changes to Wavewin. Click on the list header to display the drop down table for the latest additions and changes made to that section.

We are proud to announce the launch of the "Wavewin D" series.
Version Release Date Additions & Changes
Wavewin D.N 06 / 26 / 2008 (Show/Hide Channel Titles): Added a new dialog to give the ability to show/hide analog and digital channels via the channel title. To open the dialog select the "Show/Hide Channel Titles" option under the "Options" menu. All titles listed that have a check in the checkbox are automatically hidden when the file is displayed. To show the title uncheck the checkbox next to the title. To remove a title from the list use the "Remove" button. To add a new title type the new title in the edit box and click the "Add" button. The new title is automatically added to the end of the list and the checkbox is defaulted to checked.
Wavewin D.G 02 / 25 / 2008 (Network Drives): Corrected an error when navigating network drives. In previous versions if there are 2 sets of () in the network name Wavewin was extracting the drive letter from the first set of (). This is not the case, Windows puts the drive letter in the last set of (). In this version Wavewin extracts the drive letter from the last set of (). This corrects any access violation errors encountered when navigating to network drives.
(Network Drives): Greatly improved the speed when reading the directories under a network drive. Wavewin is now a 100% compatible with Windows explorer when navigating to network drives.
Wavewin D.D 01 / 23 / 2008 (Blink): Added a new command line parameter to blink the date and time displayed in the upper right hand corner of the menu. The new command line parameter is called "Poke". "Poke" checks the current size of the active directory with the size of the directory in Windows. If the sizes are different then the date and time will blink from red to gray. The directory sizes are checked every 8 seconds. To clear the blinking click on the refresh directory menu button.
Wavewin C.V 03 / 29 / 2007 Added the ability to merge files via the command line paramter. Batch mode is used to define the files to be merged. The files are automatically merged by time and if the files have different sampling frequencies then the highest sampling frequency is selected. A 1999 ASCII Comtrade file is saved in the same directory as the batch file with the name Merged File.cfg and Merge File.dat. If an error occurs then a Merge File.log is saved in the same directory as the batch file.
Wavewin C.R 02 / 22 / 2007 Recently we added support for the Window's 120 DPI monitor setting. When 120 DPI is set a number of dialog windows were being resized improperly. We added support to automatically resize the dialog windows.
Wavewin C.O 01 / 04 / 2007 We discovered that the Wavewin Version C.N downloaded to the web on 12/06/2006 had the wrong menus active. Wavewin C.N full version was compiled with the Comtrade versions menus. This problem has been corrected in Version C.O.
Wavewin C.I 07 / 10 / 2006 Fixed a problem when trying to access directories using networked computer names: \\other machine\fault files.
Wavewin C.D 03 / 10 / 2006 Moved the last active directory to the Wavewin.ini File. In previous versions the last active directory was saved to the Template database that has a limit of 80 characters. The Wavewin.ini eliminates the 80 character limit.
Wavewin C.A 11 / 28 / 2005 Added sorting to the table folder tree.
Always open Wavewin's folder tree to the last active directory.
Version Release Date Additions & Changes
Wavewin D.Z 05 / 31 / 2009 (Syncrophasor Support): Modified the phasor displays to follow the syncrophasor convention (+Peak=0 Degrees)
(SACS): Added 8 new SAC operators using the values calculated from the recursive engines. The new SACS operators are:
   "x": real component
   "y": imaginary component
   "m": magnitude
   "d": angle
   "r": true rms
   "f": cyclic frequency
   "q": instantaneous frequency
   "t": delta time frequency
(SACS): Added a number of examples in the SAC help window describing how to use the new and existing operators.
(Time Discontinuity): Added a new engine to detect discontinuities in time. If a time discontinuity is encountered then a green dotted line is displayed at the sample where the discontinuity occured. A mouse over the small gray triangle displayed at the bottom of the green line will show the duration. To turn off this feature set the "Show Event Separator Bars" field to "No" (in the properties dialog).
(Harmonics): Changed the displayed Total Harmonic Distortion value from RMS to Instantaneous (for compliance with IEEE notation).
(Summary): Revised the Summary Window to show: Max, Min & Max Min Difference for both Instantaneous and RMS values.

Wavewin D.L 06 / 04 / 2008 (SandC Meter Files): Added a new driver to read and display all 31 "*.PRO" files saved to the active directory. The samples are binned into memory then sorted by time before being displayed in the data plotting window. Files that have no analog channels defined in the quantity ID vector section are ignored. Also, if a channel is not defined it's titled is defaulted to "Unused" and not displayed.

Wavewin D.K 05 / 29 / 2008 (Summary): Compressed the Fault Summary information into 4 lines for the SEL compressed format. Previous versions were using 12 lines for each event saved in the file. There is a limitation of 40 lines for the fault information section. Up to 10 event's fault information is now displayed.
(Print): Included the Waveform Summary as part of the data plotting print.
(Analog Table): Added automatic column sizing according to the largest max & min values. Previous versions were using a fixed size which was causing values to overlap into neighboring columns.
(Thiran Filter): Corrected a problem with initializing the Thiran filter for the first 3 samples.
(WFC Time Stamps): Add support to use the Frame DNP time stamp when there are no primary or secondary triggers defined in the file.
(WFC Digital Channels): Added 14 new digital channels to the WFC file to show the trigger information defined in the Auxiliary data activity flag section. The cycle that defines the trigger is marked in alarm state.
(Automatically Add HTM Events): Added support to automatically add event information from the event html files that have a begin and end date and time included in the filename. The events will be automatically added if the html file is located in the same directory as the WFC and EWC files and the begin time defined in the html file name is greater than or equal to the file's start time and the file's start time is less than the end time. The events that have a common time are automatically added when the file is opened.
(EWC Scale Factor): Corrected a problem with the Extended Waveform Capture Scale Factors. Added support for the IQ24 data format.

Wavewin D.J 05 / 08 / 2008 (Thiran Filter): Corrected a problem with the Thiran filter. When calculating the relative number of samples Wavewin was using the negative value when it is greater then 1.
Wavewin D.I 04 / 17 / 2008 (Calculate Frequency): Added a new dialog to calculate the Frequency. The new dialog can be opened from the "Calculate Frequency" menu option under the "Data" menu.

Wavewin D.4 08 / 24 / 2007 Modified the Export and Import features to use a tab delimited format. The comma delimited format used in the previous version was conflicting with commas used in the device "Driver" and "EscSeq Commamd" fields.
Improved the Rochester polling driver to rename any extracted files if an error occurs during communications. Previous versions would delete the files. Also, improved saving the last polled date and time. If an error occured during communications the latest date and time polled was not being saved to the SDC-HIS.INI file.
Wavewin D.3 08 / 24 / 2007 Added a new menu option under the Device menu to export the existing device table to a comma delimited ASCII file. Export files are automatically tagged with the .CSV extension. The ASCII file contains all or selected device entries. The first line in the export file specifies the column headers.
Added a new menu option under the Device menu to import previously exported device manager files. Import will read each entry in the import file and change any existing entries with the new information and it will also add new entries if they do not exist in the open device manager table.
Wavewin D.2 08 / 22 / 2007 Added 2 new commands in the Drivers.ini file for Ethernet connections. First command "Connect", will connect to the IP address and port number specified at the active device. The second command "Disconnect" will disconnect from the IP address at the active device.
Added 3 new menu buttons. The first button allows for pinging the IP address and port number for the open device. The second button will connect to the IP address and port number for the open device and the third button will disconnect from the active device. The 3 new buttons are only displayed if the device has an IP address and port number defined in its EscSeq Command field.
Took out all ping and connection calls for IP address when the devices in the table are initialized.
Wavewin D.1 08 / 07 / 2007 Added an automatic feature to rename Mehta records upon retrieval. The new names are in accordance with the IEEE C37.232 format and the old filename tag is placed in a user field.
Added new passed parameters via the "EscSeq Command" (positions 5, 6 & 7) to allow for retrieval of 16 samples raw or filtered data. For example: you can ask for raw data at 16 samples/cycle by sending "EVE 1 R S16" to the relay. The "EVE 1" part is the default Wavewin setting, to add the "R S16" parameters you need to edit the configuration dialog and add "R S16" at the end of the command field. So if the current command is: "OTTER 1 0 x" then the new command would be "OTTER 1 0 x R S16".
Changed the polling scheme for the Ethernet ports from an event based interface to a preemptive based interface in order to synchronize the reading intervals across all ports and to eliminate the possibility of collisions with data received from the RS232/485 ports.
Added new fields to allow for disabling of the automatic save in DTB files feature and to allow for renaming of the DTB files to the IEEE C37.232 format on a periodic basis.
Wavewin D.0 07 / 23 / 2007 Added automatic detection of the loss of a TIS recorder by monitoring the sample counts of each scan. When a sample count is loss the system will automatically reset the recorder and restart the TIS configuration and capture drivers.
Wavewin C.Z 06 / 07 / 2007 Added a circular buffer for the TIS driver.
Added automatic screen updates from the TIS internal polling driver.
Added an internal driver to read the TIS configuration information.
Added triggers to the TIS internal driver.
