A new release for MBLogic has been made. This addresses a minor bug in HMIBuilder, where exceptionally long lists of address tags would not fit on the screen. This has been corrected by selecting address tags using a different method. There are no new features.

This is a bug fix release for the new HMIBuilder program. Due to an error in the script which assembled the final release, the wrong version of the icons were included with the final release package. This fixes that problem.

A bug fix release has been made for MBLogic. This fixes a minor bug in one of the web based HMI Javascript libraries ("libmbhmicontrols2.js") which caused problems with displaying tank columns on older versions of some browsers. This bug appeared in the previous release (on Friday) and was related to working around a browser bug in Webkit based browsers (Apple Safari and Google Chrome). Unfortunately, working around the bug in those web browsers introduced a bug in the Javscript library, which this release fixes.... read more

In addition, MBTools now includes a new MS Window specific GUI client for monitoring Modbus/TCP servers.

A new release of MBLibs is now available and can be downloaded directly through the file manager menu. MBLibs can be used for creating your owh customer Python software with Modbus, SBus, or soft logic functionality. This release brings the Modbus/TCP and MBLogicEngineCK library up to the same levels as the current release of the MBLogic automation platform.

Release 21 of HMIServer is now available.

A new example showing how to create a simple HMI application has been posted on the MBLogic website. It can be found at:
http://mblogic.sourceforge.net/mbhmi/simpleexample/simpleexample.html

This shows how to create a very basic HMI displaying a single number.

Due to an unknown problem the main download link on the main MBLogic project was not updated when the last release was made. This has now been fixed and the link now points to the latest release. If you were looking for the new releases (latest release was 2010-07-05) the link is now on the main page. This is the same release as was already available from the "view all files" link.

New releases for HMIServer and MBLibs. This is a clean-up release to bring the libraries in sync with the recent work in MBLogic. This also addresses requests from users of older versions of Python (2.4) and by Mac OS/X users.

Release 19 of MBLogic is now available (also in release 20 of MBLogic All). This is a significant change with an all new and greatly improved status monitoring system. Also the system now has "generic client" capability which allows the creation of communications extension modules to allow adding new protocols or accessing serial ports.

This release adds support for a new protocol - SAIA Ether SBus. This results in new versions of HMIServer, SBProbe, SBPoll, and SBusServer as well as adding the protocol to MBLibs. Also, HMIServer is now released on its own as separate package rather than as part of MBTools.

The project web site has a new section with "technology demos". This shows current and upcoming features in MBLogic. See "http://mblogic.sourceforge.net/techdemo/techdemo.html" for examples.

This release updates the installation documentation for MBLogic to account for packaging and installation changes in the latest version of a third party library (Twisted) packaging for the MS Windows version. If you are not using MS Windows, or if you already have a working installation, you can ignore this release.

A new release has been made for MBLogic and MBTools. This release builds on the previous work in making creating an HMI easier. The new HMI documentation has now been incorporated directly into the on-line help. SVG art is now more self contained instead of relying on template boilerplate definitions. Push buttons can be enabled and disabled via the data table.

A new release is now available for MBLogic and MBTools. This adds a new and greatly improved method of creating HMI web pages. The graphical portions of the web pages can now be edited using Inkscape and the HTML portions selected from templates.
