The OpenPLC is the first fully functional standardized open source PLC. We believe that opening the black-box of a PLC will create opportunities for people to study its concepts, create new technologies and share resources. The OpenPLC Project tries to be exactly what its name states. It is a standard industrial controller, with sturdy hardware and real time response. It can be programmed with all the five standard PLC languages (ST, IL, SFC, FBD and Ladder), making it compatible with programs written for other PLCs.”
