Linux Programmable Controller (LPC) - A PLC for Linux

What is it?

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. Please give me feedback. Thanks, Hugh.

I have also started to port the Java tools - the HMI tool is semi-functional. You can find it in the 'handler/demos/java_hmi' directory. To run it for now you will need to that the Java SDK from sun installed. Note: The Devicenet driver is still not functional, but it is being worked on.

Some simple bug fixes were added to the tarball for network naming, and the matd program was fixed a little more (but it is not completely ready yet.

A first (rough) version of the LPCD code that works with the MAT PLC is ready for those brave enough. Basic instructions for download and install are;

Download the mat_handler.tar.gz file (6.2 MB)
Uncompress and unpack it in an empty directory (don't mix it into the matplc directory) with,
1. gunzip mat_handler.tar.gz
2. tar -xvf mat_handler.tar
Connect to the 'mat' directory and type 'make' to compile the files.
Connect to the 'demos' directory and try it out.

Download and Install

Full Download
