Version 1.4.0: Filtering function and auto-start

Filtering function*

Some scales and balances can only send data continuously, which means you get a constant  stream of weight values at rates of typically 5 to 10 values per second. SDL can easily keep up with these rates, but if you don’t really need that many values, it would be better if it could ignore most of them.

This is where the new filtering function comes into play:

Filter received lines

In the screenshot above, we set SDL to record one line for every 10 received lines (and ignore the rest). Assuming that your scale sends 10 values per second, SDL would now only record one value per second.

Start data logging with program start*

If you enable this function, SDL will connect to your measurement device on the last used port and start data logging automatically when the program is started:
Start data logging with program startThis eliminates the need to press the start button.

*These features require a paid Plus license.

Request features and vote for those we should prioritize

Both of the features above were requested by our users. You can do so on our forum or by emailing us. You can now also vote for features on our public development board (provided by trello.com).

Other improvements

Behind the scenes, the core functionality of SDL has been reorganized and is now more modular, testable and expandable. This means that we can add new features more easily, while knowing that they will not affect the existing functionality of the program.

Bug fixes

The new architecture enabled us to find and fix two somewhat exotic bugs:

Version 1.3.3: Acculab AL and Sartorius Entris device profiles

Acculab AL and Sartorius Entris device profiles

With the help of our users, we’ve added profiles for Acculab AL balances (discontinued) and the popular Sartorius Entris series1 to the most recent release of our Simple Data Logger weight recording software. You can select these devices in the input tab and press the set default parameters button to automatically set the interface parameters:

Acculab AL default RS-232 settings

Likewise, the polling command to immediately request the weight from the balance can be set by clicking the button in the control tab:
Acculab AL balance polling command

Improvements and bug fixes

  • The software reacts faster when stopping data acquisition (e.g. when the stop button has been pressed).
  • The time format used for the auto-stop feature in the control tab is now consistent across all region settings (always HH:mm:ss).

1 Also works with Sartorius ED, GK and GW balances (according to the interface description).

Version 1.3.2: New auto-stop conditions

New features in Simple Data Logger

Data logging can now be stopped automatically if the measurement value is less than or greater than the limits entered in the control tab or if a certain number of lines has been written to the CSV file:
Auto stop data logging

Auto-stop example 1

You’re using a scale to measure the amount of liquid draining from a test object over several hours and you only want to capture the measuring values up to a certain limit. You can enter this limit in the “value greater than” field.

Auto-stop example 2

You want to open the CSV file in Microsoft Excel and do not want to exceed the maximum number of rows (1048576):
Excel maximum number of rows

A timer to stop data acquisition is also still available (as in the previous versions).

Bug fixes

  • “Ohaus SPU, TA, NV” default polling command can now be set by pressing the command button in the control tab.
  • Pressing the reset button in the settings tab will correctly reset everything (except for licenses) and these default settings will be loaded when you restart the application. Previously, SDL would incorrectly revert to the settings of a previously installed version (if present).

Version 1.2.1: New A&D, Kern, Sartorius and Scale Manufacturers Association device profiles

The latest release of our data logging software includes many new device profiles:

By selecting your scale or balance and clicking on the set default parameters for device button, you can easily set the required default interface parameters and the terminator:
Set default parameters for selected device

This also works in the control tab when polling the weight from the balance using a timer. With one click, you can set the command to request the weight immediately:
Set default command for Sartorius SICS

Version 1.2.0 released: support for Mettler Toledo SICS, new offline installer available

We’ve added an “MT-SICS” device profile for scales and balances which support the Mettler Toledo Standard Interface Command Set:
MT-SICS device profile

As an alternative to the ClickOnce installer, you can now download an alternative .msi Windows Installer Package (requires .NET Framework 4.7). Please note that settings are not shared between these two versions.

Further improvements in Simple Data Logger version 1.2.0:

  • On high DPI displays, the licensing tab contents are now resized correctly.
  • The TCP/IP protocol setting has been removed (it will be reintroduced when we add support for protocols other than ASCII/”raw TCP”), which enabled us to decrease the vertical size of the application window.
  • Minimum window sizes have been increased to ensure the application is still usable.
  • A warning is shown in the event log when polling is enabled, but no polling command has been entered.
  • An update notification is now shown in the status bar when a new version is available.

We’ve also updated our EULA and the message shown when the free version of the software is started to clarify that use in an organization (including academic institutions and non-profits) requires a paid license. You can easily purchase licenses online through our partner FastSpring (your license key and invoice will be generated automatically).

Note: If you’re already using Simple Data Logger, you may have to update manually to use the new features. Normally, the ClickOnce version can update automatically but we disabled this by mistake in the previous release. Simply go to the download page and click on install.

Version 0.4.0 (custom regular expressions)

Simple Data Logger just became significantly more powerful (and useful): You can now modify the regular expression used to match and capture data.

This is best explained with an example. Let’s say your scale sends the following data every time you press the print button:

Balance ID: 8336507294
Balance Type: STX421
Balance Name: Scout
User Name:
Project Name:
Weighing
Sample Name: OBJECT 1
123.4 g
Gross: 123.4 g G
Net: 123.4 g N
Tare: 0.0 g T
Signature:____________
Verified By:____________

However, you actually only want to record the net weight. This can now be achieved in SDL by clicking on the customize button in the device tab:

Capture net weight using custom regular expression

Adding “Net:\s*” ahead of the original regular expression ensures that only lines where these characters appear before the weight are matched. SDL then uses a capturing group (subexpression) to capture the numeric value (weight).

SDL always captures the data matched by the first subexpression. You must therefore include a subexpression (in parentheses) in your regular expression.

For further information, please read this blog post describing the same functionality of our 232key software.

We’ve also made the links in SDL clickable and made sure that user settings are automatically transferred after updating.

Finally, we’ve relaunched our website, making it significantly more interactive (try it out and leave a comment below). We’ve also moved it from simpledatalogger.com to smartlux.com/sdl.

Software for Ohaus scales with Ethernet interface

As of version 0.2.0, our Simple Data Logger software can communicate with Ohaus scales and balances equipped with an Ethernet interface. The Ethernet interface is a convenient substitute for the dated RS-232 interface.

In the Device tab, simply select “TCP/IP” and enter the IP address of your scale:
Ohaus Ethernet data logger software

Please note that the Terminator setting from the COM port group (above) is also used for TCP/IP connections. We’ll update the user interface in a future release to make this clearer.
