History

See the Updates page to download the latest versions of the PsiLog and PsiLog Link programs.

2008-02-28

Version 1.31F

• Fixes
  • No longer corrupts unload files when the amount of data unloaded is an exact multiple of 512 bytes.

2004-03-08

Version 1.30F

• Other Changes
  • Now searches for schemes on the PC by looking for only LDR files instead of SCM files and LDR files. This has halved the time taken to get the list of scheme names from the PC when selecting schemes for transfer to the Psion.

2003-11-25

Version 1.29F (not publically released)

• New Features
  • Added support for no unload number in the name of exported data files.
• Fixes
  • Reselects the telemetry switch relay (if applicable) when the communications times out and the RTS signal is toggled. Previously, the RTS toggle would cause telemetry switch relays to disconnect from the data logger.
  • Corrected vertical axis scaling in the Velocity Trace.
  • Corrected a "divide by zero" error in the Velocity Trace.
• Other Changes
  • Changed references to "scsoftware.com.au" to "scss.com.au".

2003-07-22

Version 1.28F

• Fixes
  • Lotus 1-2-3 export now works.
• Other Changes
  • Lotus 1-2-3 export now three times faster.

2003-07-15

Version 1.27F

• New Features
  • Can export unload files as text (tab or comma delimited) or Lotus 1-2-3 worksheet (WK1) files directly to the PC.
  • Tweaked plot X-axis labelling. For example, if the steps between axis ticks are exact multiple of 60 seconds, then there is no point showing the seconds part which allows more significant parts such as hours to be shown.
• Fixes
  • No longer intermittently crashes (usually with the message 'Process exit code 37') when using the Select Mode Window (Space) to switch between modes.
  • No longer continually reports 'Timeout' if the logger buffer viewer function is selected when no data logger is connected. It will now give up after a few attempts.
  • Plot date/time range window now updates to correct values after cancelling a zoom.
  • Added checks to ensure only one copy of PsiLog can be running at once.

2003-03-05

Version 1.26F

• Fixes
  • No longer fails to transfer multiple unload files belonging to the same scheme to the PC.
  • No longer adds blank lines to V3 unload index files.

2003-02-11

Version 1.25F

• Fixes
  • No longer intermittently shows "Invalid arguments" error upon exiting PsiLog when in the Data Viewer mode, or when switching from the Data Viewer mode to a different mode.
  • No longer shows "String too long" message when there is not enough memory to allocate the communications buffer.

2003-02-04

Version 1.24F

• New Features
  • Total plotting time (including ranging and actual plotting) will in most cases take 55% of the time compared to V1.23F - almost a doubling of speed!
  • Data viewer plot ranging now shows percentage progress.
  • Data viewer plot ranging is faster for event-based schemes.
  • Data viewer tabular view "Find date" is much faster (practically instantaneous in many cases).
• Fixes
  • Data viewer tabular view now correctly calculates the values of channels using formulas that depend on the results of calculations involving other formulas (for example, thermocouples and their cold junction thermistor).
  • Plot viewer no longer intermittently shows a shaded area when zooming out.

2003-01-30

Version 1.23F (and PsiLog Link v1.4)

• New Features
  • Many improvements to the Data Viewer plotting function:
    • Determining the ranges is now about twice as fast.
    • Zooming in on fixed log interval files is faster.
    • Improved selection of log entry to plot.
    • Date/time display window. This shows the date/time extents of the currently selected range of unload data. It can be repositioned and turned on and off.
    • Labelling of the X-axis has been improved so that ticks appear at sensible intervals (for example, on the hour, half-hour, etc, as appropriate). It also allows for more ticks and labels to fit along the axis.
    • Labelling of the Y-axis has been improved to rescale when zooming in to better fit the displayed data, to allow for more ticks, and to minimise the size of the labels. Where appropriate, label values will be rescaled to powers of ten, with powers rounded to multiples of three.
    • Addition of gridlines. New preferences allow the selection of none, black, grey, solid, and dotted gridlines individually for each axis.
  • The Select Unload dialog now allows key presses to jump the highlight to files starting with the key's character.
  • Messages displayed by PsiLog Link have been altered to better indicate the state of the link.
• Fixes
  • Data viewer plot now correctly calculates the values of log entries using formulas that depend on the results of calculations involving other formulas (for example, thermocouples and their cold junction thermistor).
  • The Select Unload dialog now allows enough room to fully display the unload filenames with character descenders (on letters like 'g' and 'y') that were previously being chopped off.
• Other Changes
  • Minor tweaks to the Version window and Mode Selection window.

2002-10-31

Version 1.22F

• Fixes
  • Fixed incorrect date/times in unload files when performing incremental unloads of schemes using linear (stop when full) buffers.

2002-10-18

Version 1.21F

• Fixes
  • Fixed incorrect date/times in Starlog Version 2 unload files of schemes using linear (stop when full) buffers.
  • Fixed "ENT:Procedure not found" message in Data Viewer.
  • Fixed Buffer viewer in Data Viewer not always detecting changes to the log buffer and hence not automatically updating.

2002-10-12

Version 1.20F

• Fixes
  • Transfer of unload data to Starlog Version 2 software now works.
  • Removed "Loading CDTDone" message when programming loggers.
• Other Changes
  • Improved speed of transfers of unload files to PC.

2002-09-19

Version 1.19F (and PsiLog Link v1.3)

• Fixes
  • Fixed PsiLog Link connection problems when running under Windows 98.
  • Fixed "Scheme corrupt" error messages when unloading loggers.

2002-08-15

Version 1.18F

• Fixes
  • Fixed support for 5 minute scan intervals. DWLR loggers and schemes were not affected by this problem. Symptoms include an "Overflow" error programming schemes (and subsequent failure to program) and obviously incorrect dates (eg. year 2100). Unload files were nevertheless intact and displayed correctly when transferred to the PC, although the dates in the unload file list were incorrect.

2002-07-30

Version 1.17F

• Fixes
  • Fixed memory corruption error involving the Formula Tester.

2002-07-19

Version 1.16F (and PsiLog Link v1.2)

  • Added 38400 to the baud rates PsiLog Link supports.
  • Fixed some user interface glitches.
• Other Changes
  • Updated install system:
    • Fixed some uninstall problems.
    • Windows 3.x is no longer supported.
    • Can now select which components to install.

2002-06-03

Version 1.15F (and PsiLog Link v1.1)

• New Features
  • Packages sold now come with an all-Windows installation program (at last!) and Windows Link software. MS-DOS is no longer supported.
  • Modem dialog now searches for schemes on all local drives.
• Fixes
  • Fixed bug preventing programming of Macro loggers.
  • Fixed 'Panic 73' putting DWLR loggers to sleep.

2002-05-16

Version 1.14F

• New Features
  • Now compatible with the DWLR and other loggers which support extra-long scan intervals. A shorter communications timeout of 10 seconds is recommended for such loggers.
  • The Scheme Test Display function now searches all local disks looking for the scheme FTU file.
  • The Data Viewer Logger Buffer display now searches all local disks looking for the scheme ENT file.
• Fixes
  • Fixed "Divide by 0" error in Velocity Trace.
  • Fixed some 'Panic' bugs introduced in v1.13F.

2002-03-04

Version 1.13F

• New Features
  • Added support for multidrop communications.
  • Enhanced scheme selection so that schemes on all local disks are listed when programming a logger or deleting a scheme.
  • Mode selection window now allows the arrow keys and Enter to select a new mode.
• Fixes
  • Fixed "File not found" error programming schemes without KBD files.

2001-10-31

Version 1.12F

• New Features
  • New Data Viewer mode available.
    • View your data as it's being logged.
    • View unload files.
    • Plot unload data.
  • New Velocity Trace mode available.
  • New Select Mode window to allow for single-finger selection of the mode (i.e. you don't need to hold down Psion-Shift-letter anymore).
  • Added an option to have PsiLog automatically start on Workabout computers.
  • Added delete scheme files function.
  • Added delete unload files function.
  • Added automatic update facility.
  • Zoom supports a fifth slightly smaller font to squeeze more onto the small Workabout screen!
• Fixes
  • Unloader now checks for disk space before, instead of during, the unload.
  • Fixed issue relating to excessive communications errors during unloads. This caused unloads to be significantly slower than they should have been - sometimes failing altogether!
  • Fixed problem with PsiLog failing to automatically delete unload files after transfer to PC.
  • Fixed problem with incremental unloading reverting to a full unload on every other unload.
  • Fixed serial communications attempting to send >1024 bytes to the logger in one go (loggers cannot receive that much all at once).
  • Fixed problems programming Version 2 software schemes (logger version detection and KBD loading).
  • Fixed problem where the unload selection dialog was using the scheme program directory preference instead of the unload files directory preference.
  • Fixed problem recognising the Help key.
• Other Changes
  • As a result of one of the above fixes, the unload file directory preference is now a General Scheme preference.
  • Improved PC Link compatibility with older Workabouts.
  • Properly centered PsiLog Version window.
  • Removed the Base 36 Converter.
  • Removed "Auto off" Communications preference.

2001-07-02

Version 1.11F

• Fixes
  • Fixed problem programming schemes with large KBD definitions.

2001-03-02

Version 1.10F

• New Features
  • Added modem dialout support.

2001-01-10

Version 1.09F

• New Features
  • Copied extra scheme INI settings.
• Fixes
  • Miscellaneous bug fixes.

2000-10-29

Version 1.08F

• New Features
  • Added localisation/translation support.

2000-10-24

Version 1.07F

• Fixes
  • Improved reliability of connection to PC link server.
  • Fixed display of times in test mode.
• Other Changes
  • Demo expiration extended to the end of the year. Expiration limits unloads to 50 logs while allowing full functionality in all other areas.

2000-10-02

Version 1.06F

• New Features
  • Online help now reasonably complete. It is yet to be reviewed, though, and needs some cleaning up.
• Fixes
  • Fixed some 'Panic' bugs.
• Other Changes
  • Lengthened the demo expiration again.

2000-06-21

Version 1.05B

This will be the final demo version before the software is released. There have been no bug reports, so I assume the software is quite stable. There is no new online help.

• New Features
  • Added complete file transfer functions for the existing modules:
    • Copying formulas from PC to Psion
    • Copying scheme files from PC to Psion
    • Copying unloaded data from Psion to PC
    • Synchronising IUP files between the PC and the Psion
    • Copying 'System' FTU files from the PC to the Psion
  • To remind you what window/mode PsiLog is in, there is a new Mode Display - a black strip showing the current mode. It can be turned off via the User Interface Preferences.
  • Enhanced the Test Display module so that if you decide not to have a copy of the formulas on the Psion, you can load FTU screens that don't use formulas.
  • The formulas (if you have any) now start loading immediately PsiLog starts without waiting for the splash dialog to be acknowledged.
• Other Changes
  • Now that Starlog software files are easily copyable from the PC, they are no longer distributed with the demo.

2000-06-10

Version 1.04B

• New Features
  • Formula loading is now twice as fast.
• Fixes
  • Logger programming now works. Loggers are configured correctly and the LCD display now shows up with the correct text and no nasty boxes.
  • The LCD display bug also affected the Putting of strings by the Test display module.

2000-06-08

Version 1.03B

• New Features
  • Logger programming implemented. However, you will need to copy the scheme files to the Psion yourself for now. Set the directory in the "Program logger preferences" dialog. PsiLog understands the following Starlog Version 3 scheme files: LDR, CDT, KBD, INI. PsiLog understands the following Starlog Version 2 scheme files: LDR, CDT, CFG, KBD. Note that any Macro logger CFG files must have the same base name as the scheme in order for PsiLog to find the CFG file. For example, if you have a scheme called RMTEMP and it uses the MACRO32.CFG file, then MACRO32.CFG must be copied as RMTEMP.CFG in order for it to work. Testing has been performed only on a Red Starlogger, but programming should work for all loggers.
  • Logger unloading is faster. For MX-series machines (27.684MHz) it is about 160% faster, for older machines (7.68MHz) it is about 290% faster! All Psion machines can now unload loggers in better than 110% of the time taken by V3 software. To achieve this performance make sure the following preferences have been set:
    • General, User interface, Cache size: at least 8000 You will need to exit and restart PsiLog for changes to this option to take effect.
    • General, Communications, Buffer size: at least 8500.
    • Unload logger, Preferences, Request size: 4096 (this is the same as V3 software).
  • The Unload logger mode window now shows memory usage information for the Internal disk and any SSD plugged into the A and B SSD slots.
  • The Test display mode now has a 'Scheme test display' option. This reads the scheme name from the connected logger and automatically looks for the relevant FTU file. Set the directory that holds these FTU files in the Test display preferences dialog.
  • Pressing the Spacebar will show you what mode/window the software is in.
• Fixes
  • Fixed an 'Overflow' error that sometimes appeared when loading FTU screens.
  • Fixed some 'Stray signal death' errors. Note that these messages have changed to become System Panics - 'Process exited: Exit 143'.
• Other Changes
  • The Test display 'Address' and 'Step size' options merged into one.
  • Communications window preferences have changed slightly.

2000-02-06

Version 1.01B

• Other Changes
  • Cosmetic release for change of name from PDLFTU to PsiLog, change of program icon to use a Workabout look, and addition of SCSS logo to program startup. The screen shots on this web page were updated to use Workabout screen layouts instead of 3a/3c/3mx screen layouts.

1999-10-02

Version 1.00B

• New Features
  • Well, finally some progress! This application has been in the works for more than a year now and has just reached Beta release!
