Decoding GADS OS Version Numbers

by ronfluegge 8. August 2015 11:49

The GADS OS software uses a version numbering scheme composed of four sets of numbers.  Here's how to decode it!

          {major version number}●{minor version number}●{build number}●{update number}

The first number is the major version number, and it refers to the year the particular version of the application was compiled (e.g., 15=2015,14=2014, etc.).

The second number is the minor version number, and it refers to the month the particular version of the application was compiled (1-12).

The third number is the build number, and it refers to the day of the month the particular version of the application was compiled (1-31).

The fourth, and last number, is the update number, and it is used to identify the update number if more than one compile of the source code is "released" on a given date (0,1,2,3,...). 

Therefore, if your version is shown as, then your version was compiled on 4/15/2013 and was the first released (0) version on that date.

So, there you go…  You now know how to read GADS OS's version numbers!

2015 Release Status

by ronfluegge 4. June 2015 10:29

There have been no major updates/releases yet for 2015.  Once the NERC GADS Working Group finalizes the cause code list for 2015, we’ll have an update announcement; otherwise, there have been no changes in either code or NERC GADS requirements to warrant a new release at this time.

The 15.x.x.x release will require Microsoft .Net Framework 4.5.2. (The first number in the version is the release year so 15.x.x.x is a 2015 release)

GADS OS prior to Version is based on Framework 3.5 SP1 that was released on 08/11/2008. There will no longer be Microsoft mainstream support for the Framework 3.5 SP1 version after January 13, 2015 (service pack support end date: 04/09/2013) … i.e., no longer supported on this date.

Microsoft recommends that customers and developers using .NET Framework 4, 4.5, or 4.5.1 complete the in-place update to .NET Framework 4.5.2 before January 12, 2016 to continue receiving technical support and more importantly security updates.

Framework 4.5.2 was released on 05/05/2014 and is released for the following supported platforms: Windows 8/8.1, Windows 7 Service Pack 1, Windows Vista SP2, plus Windows Server 2012/2012 R2, and Windows Server 2008 SP2/2008 R2 SP1.

There are no significant code changes in going from 14.x.x.x to 15.x.x.x; just compiler changes required to target Framework 4.5.2.

GADS Open Source Version Posted

Even though NERC and the ISOs have not identified any new GADS mandated changes for 2013, we highly recommend that you install this update because this release includes cumulative minor updates since the major release in December 2011.  The list of changes can be found at .

If you are a non-North American user, you generally will not be affected by these minor changes unless you indicate that you are planning to submit data to NERC in the Unit Setup Console software.

Therefore, you should consider updating your current version if you are experiencing any issues with your currently installed version; however, if you are not having issues and/or have installed the minor updates over the last 12 months, you may not need to install this update.

If you do install any of the module updates, we recommend a full update of ALL GADS/OS apps.

The full installation and source code can be found at

and at

Except for bug fixes, the next major release is currently scheduled for approximately May 2013 to follow any mid-year NERC updates.

The current GADS OS Windows version is built on Microsoft Framework 3.5 SP1 which was released on November 18, 2008 and whose support will end on January 13, 2015.

We also have available two new release candidate versions for installation:  a WPF GADS OS standalone version and a WPF GADS OS XBAP version.  They can be downloaded at .  You can also install either or both of them as needed.

These are also being released as a set of free and open source software tools and licensed under the same GNU General Public License Version 2.

The WPF GADS OS standalone version is a Windows application and will replace the current Windows version on January 1, 2014.  This will allow for a 1 year "grace period" before there will no longer be Microsoft support for the current version on January 13, 2015.

WPF XAML browser applications (XBAPs) combine features of both Web applications and Windows rich-client applications. Like Web applications, XBAPs can be deployed to a Web server and started from Internet Explorer, Google Chrome, or Firefox.  This supersedes the old GADS NxL web-based version.

We still support Microsoft Access, Microsoft SQL Server and Oracle databases.

What we are working on for the next updates in priority order:

1. A new report that shows the Operating Hours between Outages.  It will include startup date/time (breaker closed), stop date/time (breaker opened) and hours online for each continuous run on a unit basis.
2. Expanded data collection and reporting for jointly owned units. 
3. Adding capability to create the Generation Equipment Status upload file for the Canadian Electricity Association (CEA) Equipment Reliability
