Linux Programmable Controller (LPC) - A PLC for Linux This is software that will eventually replace the functionality provided by PLCs. The software is being (re)developed to use the MAT PLC as the underlying architecture. Currently offered features are listed below, and will be continually upgraded. The software is released as open source under the GPL.
TRiLOGI software is the industry's most user-friendly Ladder Logic Editor + Simulator Software. An educational/evaluation version of this program is available for FREE downloading here! This highly acclaimed PLC (programmable logic controller) software has been used by many companies, colleges and technical institutes in many countries to train new users on ladder logic programming, including Australia's RMIT, TAFE and USA's Old Dominion University, Purdue University, Kent State University, etc. It is the only free ladder logic software which allows real-time, off-line simulation of users' programs on the fly on any IBM compatible PCs! This makes it a highly productive tool for new users or students to learn ladder logic programming without having to fight for often limited "PLC training stations".
The software is actually an evaluation version of our TRiLOGI Ladder Logic Editor, Simulator and Downloader software used for programming our entire range of Programmable Controllers. The only difference being that the evaluation version does not support communication with the actual PLC, which is NOT needed at all for simulation test of the ladder program.
