After four months of development we (the Lintouch Team) are proud to announce the availability of the new stable release of the Lintouch Server, Lintouch Runtime, and Lintouch Editor.
This is the maintenance version including bug fixes and several new features. You are welcome to download, install, test, and use this version.
Please see the section called “What is Lintouch” for more information about Lintouch.
- Bug fixes
Fixed a bug that prevented Modbus/TCP plug-in from running properly on Big Endian platforms.
Modbus/TCP Master plug-in now generates unique transaction ID for every variable he is asking for. The previous behavior could have been confusing for some Modbus slaves.
- Modbus/TCP Master Plug-in Improvements
A couple of new parameters were added:
unitid - target unit id. Also known as slave id. Default is 0.
serialize - 0 means that the modbus requests will be sent in parallel for maximum performance of the plug-in. Although the parallel sending might not work for some weak Modbus/TCP slaves. When serialize is equal to 1, the plug-in will wait for response after each request sent. This is safer but slower way.
timeout - this parameter specifies time out interval for socket operations. The value is in milliseconds. Default is 200. Increase for slow devices.
See Modbus/TCP README for more details on Modbus/TCP plug-in.
- New Feature: Data Logging
A new data logging facility was implemented in the server. Lintouch is now able to log every data change that comes through connection plug-ins as well as from the Lintouch Runtimes. The data change events are passed over to active logging plug-ins, which log the event either to a console, file or a remote device (an SQL server), depending on logging plug-in implementation. Which logging plug-ins should be active for the project might be configured through a new Lintouch Editor Dialog "Server Logging". As of version 1.10, console and file logging plug-ins are implemented.
Lintouch can be downloaded and installed directly on the Windows and Linux based platforms. The detailed instructions are available at our web site.
The list of supported platforms includes Microsoft Windows 2000/XP, SuSE Linux 10, Debian/GNU Linux 3.1 (sarge), and Ubuntu Linux 5.04 (breezy). Source RPM archives are provided in order to support other RPM based Linux distributions.
The source code of Lintouch Runtime, Lintouch Server, and Lintouch Editor is distributed under the GNU General Public License 2. It can be downloaded and compiled by hand. The detailed instructions are available at our website.
Lintouch is an opensource HMI software. It lets you design user interfaces for process automation. Lintouch runs on most popular hardware and software platforms, is lightweight and easily extensible.
Lintouch supports variety of hardware/software platforms (Win32+Intel, Linux+Intel, Linux+PPC).
Lintouch has been designed with extensibility in mind. New Server Plugins can be developed to bring in new connectivity (ModBus/TCP, and Hilscher already available). New Templates (GUI Objects) can be implemented to define new control and visualization primitives (Buttons, Lamps, and other Technical Objects already available).
