Industrial PC

Control's executive editor, Jim Montague, tries to answer some questions about the changing nature of industrial PCs and asks for readers to contribute their thoughts as well. Many industrial PCs no longer need the keyboard and screens of the past and can run in headless configurations on DIN rails, on boards and in chips. So how is it possible to define, write about and use them? Are the enclosure-based PCs of the past still useful? All these questions prompted a variety of answers.
