An electronic survey of Control Design readers was conducted in April 2013 in order to identify usage and application trends of HMI & industrial PCs among the industrial machine builders that comprise Control Design's readership.
The majority of respondents (74.7%) indicated the operator interface hardware installed on their machines was a graphical display with touchscreen, followed by graphical display with key board or other input device (20.7), text-based display with integral input keys (3.5%), and discrete panel switches and lights only (1.2).
