I have gotten curious about something as I read various tech trends, and maybe some of you all will know how to answer this. In the manufacturing industry, there are types of plants where you need centralized control for various components of a processing plant, like for example an oil refinery. A small scale type would have say 4 computers in an operator's control room running an HMI foroperator's input to plant control. These PCs usually havehardware and software that has connected them to whatever is controlling plant processes directly - usually PLCs or DCS or something like that. I think OPC is the industry standard for communication between PCs, PLCs, data loggers, historians, and other kinds of things in this kind of application. Naturally, since the operators are using computers, even if the computers are kind of locked out from regular use like soritng files and surfing theinternet, there would need to besome sort of security on these computers. There would need to be virus protection, firewalls, and other kinds of things. Manufacturers usually spend tons of money on windows based computers with a kind of software like Wonderware as the operator's HMI. However, there are some new companies that have developed Java based HMI applications that run fully on a linux pc (because it's java). I would be very interested to know if anyone out there knows someone who has designed/built a system with openSUSE running on the operator's HMIs. I have heard of Ubuntu being used in this sort of application, but I have not yet heard of openSUSE being used. -- George Olson Box #1: 12.3 | KDE 4.10 | AMD Phenom IIX4 | 64 | ATI Radeon HD 3300 | 16GB Box #2: 12.2 | KDE 4.9.2 | AMD Athlon X3 | 64 | nVidia C61 GeForce 7025 | 4GB Laptop: 12.3 | KDE 4.10 | Core i7-2620M | 64 | Intel HD Graphics 3000 | 8GB -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
