INDUSTRIAL CONTROLLERS: PAC,PLC & LINUX
Linux support for industrial hardware like PAC or PLC, in the case of the big and well known brands is basically non-existent. Some hardware is based on "exotic" architectures, however the vast majority have in their guts an x86 or ARM based system (Linux friendly architectures!), but the development and management tools remain developed for Windows operating system!
There are so many reasons (commercial, technical, philosophic) that perpetuates same situation. Searching on the web, we can find some PLC/PAC related applications developed for Linux, but practically all of them are communication drivers (for the open and well documented protocols!) , developed by enthusiasts
