Operator Interface Resource Center

Controls engineers need a variety of information on topics such as display terminals, HMI software, industrial PCs, alarm & annunciation, data acquisition and touchscreens.

Display terminals provide varying levels of operator interface from simple panel meters and text messages to graphical representations of entire processes by use of various types of HMI software.

Industrial PCs are ruggedized versions of PC technology that are suitable for industrial environments, largely by eliminating moving parts and providing more-protective enclosures.

Touchscreens are an alternative to keyboard or pointing device data entry, working well with graphical operator interface software, and providing prompt response to machine alarms.

Timely news, back-to-basics primers, feature articles, technical white papers and descriptions of the latest products all provide valuable insights that can be used in designing and building machine controls.
