"Acting on Web-site feedback from automation engineers, startup Control.com Inc. has announced plans to do what no industrial supplier has dared before -- develop a Linux-based programmable logic controller."
"The concept behind the company's plan, known as the Puffin PLC project, is to create a "soft PLC," a PC-based control system that incorporates the ladder logic and flowcharting abilities of conventional PLCs. Like all PLCs, the system would be used to control industrial processes."
"Unlike conventional PLCs, the Puffin PLC would give automation engineers access to free and open source code, which will be layered atop a Linux-based operating system. Although PC-based industrial control software is already available from companies like Steeplechase Software (Ann Arbor, Mich.) and Think & Do Software (Ann Arbor), such software is typically based on Windows NT or Windows 2000 operating systems, which are not considered open to users."
