05-Jan-2016: pvbrowser-4.8.3 published.

  Many thanks to the tireless attacks from the internet against our server that
  helped us to harden our software.
  These tireless efforts from chinese ip addresses have been a very good test 
  environment for stress testing our server.
  - We can now manage to handle many connection requests from clients 
    within much less than a second.
  - The server does no longer call "exit" when more than MAX_CLIENTS try to connect.
    Instead we ignore those requests.
  As a result pvbrowser-4.8.3 is published.
  Note: The client on Android and OS-X have not been updated, 
        because they are not affected.

Support for Siemens LOGO! 0BA7 plc.

fake_qmake tool that can substitute qmake and thus allows pvserver development without the Qt SDK.

28-May-2013: pvbrowser-4.7.5 published.

Now we support DCS (distributed control system) with state machine and closed loop controllers.

Some bug fixes. An important bug which was fixed is a memory leak of 2 bytes / client in pvserver. According to valgrind there are no memory leaks.

26-Apr-2013: Bugfix release pvbrowser-4.7.4 published.

Within rllib rlsocket.cpp a severe bug was reported. Because of the bug socket file handles were not closed in case of a connection failure thus running short of file handles. This release of pvbrowser fixes the issue.

The pvbrowser client had not been affected by the issue. Also pvservers are not affected by the issue as long as you did not use rlSocket in there. But applications like daemons for data acquisition over TCP are affected for example.

26-Mar-2013: pvbrowser-4.7.3 published.

Change of mutex in rlSharedMemory because of Windows 7 support (see below). OpenGL support now also on OS-X. The OS-X DMG package now includes the Qt libraries. Thus it is sufficient to download pvbrowser.dmg only for getting the pvbrowser client. The coordinates send at mouse movement within QwtPlot widgets have been fixed. The whole connection_block used by rlSiemensTCP can now be set. You can now specify any TSAP combination. A new tool "fake_qmake" is included in our package. It can replace the original qmake from the Qt Framework but has less features. Nevertheless it is sufficient for building our pvserver. Because of this Windows users need no longer to install the Qt SDK when they want to use pvbrowser. Only MinGW is necessary then. If the original qmake is available "fake_qmake" will call the original. pvbrowser now compiles with the Qt5 version of Qt also.

ATTENTION: rlSharedMemory now uses a different mutex mechanism (file lock). You must download pvbaddon.tar.gz again if you use daemons from pvbaddon for data acquisition. Otherwise the old daemon and a new pvserver would use different mutex versions which will not work.

01-Jan-2013: pvbrowser-4.7.2 published.

2 issues with SVG graphics fixed, which were related to files generated by dot (graphviz). Statemachines see rlstate.h

06-Nov-2012: pvbrowser-4.7.1 published.

Improved integration of pvdevelop and Qt Creator. Optimized rlSiemensTCP. rlSetsockopt and rlGetsockopt added to rlSocket. Stylesheets are now supported by Qt widgets.

11-Sep-2012: pvbrowser-4.7.0 published.

Language translation for pvserver with ini files, pvtr("text"). See pvb.en.pdf "Programming->Language translations", Page 91-92

10-Mar-2012: New webpage for pvbrowser.

25-Feb-2012: pvbrowser 4.6.8 fixes a problem with showing html files from local file when using Qt version ≥ 4.8.0

19-Dec-2011: pvbrowser 4.6.7 fixes a fatal bug on Windows when using the WebKit SVG renderer. WebKit runs within a separate thread and will use the "new" operator. This comes into conflict with our own thread when you run on Windows. There the "new" operator is not thread save. At least MinGW does not care for it and does not surround this critical section with a mutex. Since even the "-mthread" does not fix it, we avoid using the "new" operator within our own code when we call the WebKit SVG renderer. See file: pvb/pvbrowser/QDrawWidget.cpp method: pvSvgAnimator::update() Also some improvements and cleanups were done when rendering SVG graphics. For example the SVG can be zoomed with Ctrl+mouseWheel .
29-Nov-2011: pvbrowser 4.6.6 published. Qt provides 2 different SVG renderers. The QSvgRenderer only supports the SVG Tiny standard. But now you can also use the SVG renderer from WebKit which supports more SVG features. It can render shades for example but filters are still not supported. You can switch to the WebKit SVG renderer when you insert the following line to the pvbrowser options. use_webkit_for_svg=1 # 0|1 Otherwise QSvgRenderer will be used as before. Attention: When using the WebKit SVG renderer pvRequestBoundsOnElement() is currently not supported. New class rlStatemachine Useing this class you can implement statemachines for use in a SoftPLC for example. Fix in decode(text) (Utf8/ISO) to support openSUSE 12.1
28-Oct-2011: pvbrowser 4.6.5 published. This version fixes an inaccuracy in text positioning within SVG graphics.
26-Oct-2011: The development version of pvbrowser in our git repository now supports zooming of the whole mask with CTRL+MouseWheel.
11-Oct-2011: pvbrowser 4.6.4 published. New class rlReport for generating reports with LaTeX. Provide static libraries also. Some fixes.
04-Jul-2011: pvbrowser 4.6.3 published. The pvservers now support allow and deny files for defining ranges of IP addresse allowed to connect. A Android client is now available. The array for lines in the QDraw widget now has no upper limit anymore. Added functions to print HTML, SVG on printer attached to the client.
09-Jun-2011: pvbrowser client now running on Android emulator. The first user now has reported that it runs on his mobile device. Currently there are 2 message boxes when connecting for diagnostic purposes. These message boxes will be removed when more devices have been tested.
05-Apr-2011: pvbrowser 4.6.2 Extensions and fixes on Lua and Webkit. Hint: delete ~/.pvbrowser.ini (Linux) or %USERPROFILE%\pvbrowser.ini (Windows) because there are some new options in the INI file. If you do not delete the INI file you can't use these options.
03-Apr-2011: User "xvedra " on our forum reported that pvbrowser runs on Mini2440 | S3C2440 ARM9 Board .
Pvbrowser (server, client and daemon modbus) works without problems into
mini2440, compiling code with QtCreator.
A cheap option for a portable SCADA.
See blog and videos at http://xvedra.blogspot.com/.

The document must be downloaded first. Using a right click on a table you can now save the table as CSV or open it in ooffice or excel. Translating language using rlIniFile i18n added.
04-May-2009: pvbrowser 4.3.8 Clicking on SVG objects now sends the correct BoundsOnElement for complex objects also (SVG objects can now produce clicked events). This is due to a bug fix in Qt 4.5. The fix is in effect on windows and linux systems that already use Qt 4.5 (The mac version will be updated soon). Help Files for the Qt Creator IDE are available under Download->Additional.
23-Mar-2009: Now binary packages are also available for Debian/Ubuntu (not only openSUSE/Fedora/Mandrake). Search for "pvbrowser" at openSUSE Buildservice .
17-Mar-2009: User "rkl099" from our forum contributed an implementation of the DCON protocol for pvbrowser. It is included within pvbaddon.tar.gz . The simple DCON daemon might also be usefull for someone searching for an example on using rlSerial, rlSharedMemory, rlMailbox and rlThread.

QInputDialog fixed to support UTF8 also. You can allocate additional widgets after the widgets that are designed graphically by setting "p->num_additional_widgets = number;" before constructing your mask. Thus you can construct additional widgets also by algorithm.
15-Dec-2008: pvbrowser-4.3.4 some new functions for OpenGL support.
11-Nov-2008: IPv6 now supported.
03-Oct-2008: published pvbrower-4.3.1 fixing issues since july 2008.

12-Feb-2008: Thanks to Kurt Braun we now support Allen Bradley PLC's Ethernet/IP with the use of TuxEIP . pvbrowser now also supports tabbed browsing. That is, you can connect to many pvservers at the same time using 1 tab for each pvserver. Attention: When testing tabbed browsing we detected a problem within the pvserver library. Because the pvserver can be multi threaded critical sections must be locked/unlocked. It turned out that memory free() isn't thread save and must be also handled as a critical section. This problem is now fixed within the library. Thus you need to recompile your pvserver in order to take advantage of this fix.
29-Jan-2008: updated documentation.
04-Jan-2008: Added support for Python programming within pvserver. Added import/export for Qt Designer ui-files.

06-Apr-2006: moving to virtual root server finished. Content of http://pvbrowser.org http://pvbrowser.de and https://pvbrowser.de should be the same. New subversion 2.8.5 available on local download (not sourceforge). Version info of client available.
Mar-2006: Moveing our website to a virtual root server at http://pvbrowser.de.

13-Mar-2006: received some screenshots from http://www.awite.com.

09-Mar-2006: pvbrowser at OpenVMS.
Since our port of the Qt2 Series to OpenVMS has not been integrated by Trolltech, only pvserver development is supported under OpenVMS.
Otherwise on OpenVMS we would have no QTable, Qwt, OpenGL and VTK available.

08-Mar-2006: License clearyfied.
Trying to found a joined venture. More is following.
Packages updated.
pvserver development is easier on Linux (Qt Designer Version 3). On Windows install MS VisualC++ 6.0 or higher.
OpenGL and VTK have to be fixed on Linux. Windows OK.

19-Feb-2006: Added Sourceforge-Link to topic->home

16-Jan-2006: DSL Problem in our Hometown
04-Dec-2005: Branched a commercial version of pvbrowser. Best regards: S. Lehrig, Finkenstr. 3, D-57368 Lennestadt-Saalhausen
14-Nov-2005: New Subversion. pvbrowser can be compiled using GCC4. New functions: pvMysqldump() pvCSVcreate() pvCSVdump() pvCSV()

27-Aug-2005: Preview of pvbrowser with Qt4.0.1 . QWT is currently commented out. Qt4 must be improved before release.

22-Aug-2005: New subversion 2.8.2 of pvbrowser. Extended generator ui2pvc (Assignment of physical values from within Qt Designer). Extended pvbuilder. Extended online help system.

18-Aug-2005: We really tried to provide Netscape Plugins of pvbrowser for Firefox, Mozilla, Netscape and Opera. For this we used the classes provided by Qt. The result is very disappointing. The plugin is very very slow. And furthermore it has different quality in the different browsers and under Linux and Windows. In contrast the kpart for konqueror runs practiacally as good as the standalone pvbrowser. Thus we will not propagate browser plugins.

06-Aug-2005: New version 2.8 of pvbrowser. pvbrowser provides a kpart for integration into konqueror or firefox now. Layout Management is now implemented. Input Layout in Qt Designer. Code will be generated by ui2pvc. Soap XML file, containing widget information can be generated by ui2pvc.

02-Jul-2005: ui2pvc will optionally generate a soap xml file. Using the information in the xml file, you can generate the code for data acquisition. This can be used to create pvservers without manual programming.

02-Jul-2005: Integration of Hilscher Profibus cards is delayed, because Hilscher currently does not provide support for PCMCIA Profibus cards. We first will have to extend the Hilscher driver.

26-Mar-2005: Today I made a fix in rlSiemensTCP. "Merker" and "Datenbaustein" had been exchanged. Please load rllib from our download page.

19-Mar-2005: Today we have tested Siemens S7-300 PLC. Now Siemens S7-200, S7-300 and S7-400 are tested. Please load rllib from our download page.

09-Mar-2005: Today I received a PROFIBUS-DP/FMS-Master card + PROFIBUS-DP-Slave Testboard. I will be busy for a while.

08-Mar-2005: Data Acquisition now integrated in pvbuilder.

06-Mar-2005: External plot tools like gnuplot or ploticus may be used in pvbrowser. These tools will produce temporary files. For these temporary files you may use p->file_prefix so that file names become unique. The temporary files starting with p->file_prefix will be automatically deleted when the user disconnects. Start the plot tool from pvserver using system(). The result of the plot tools will be a bitmap file. Use pvDownloadFileAs() and pvSetImage() to bind these bitmap files into your visualization. Example.

06-Mar-2005: Users of rllib reported that rlSiemensTCP works with S7-400 and corresponding VIPA PLC's. You have to configure fetch/write on your PLC. S7-200 has been tested before. S7-300 is not tested jet.

06-Mar-2005: pvbrowser now has a new application "pvbuilder". Using "pvbuilder" you can create and maintain pvserver projects. Simply choose "File->new visualization" to create a new project. When Qt Designer pops up, create a new dialog with all your widgets. After this you can run your pvserver the first time. It is also possible to define PLC access from "pvbuilder".

06-Mar-2005: Forum closed because of destructive elements in the internet.
