Key requirements for industrial process controllers include which of the following? (Select all that apply.)
A. Availability
B. Timeliness
C. Industrial interfacing
D. Confidentiality
A, B, C. Availability, timeliness, industrial interfacing.
Process control is a time-sensitive operation that requires quick response times. IT systems generally do not have timeliness constraints. For this reason, frontline intelligent process controllers operate on real-time operating systems. Industrial controllers typically provide few if any user-friendly interface features, such as keyboards, pointing devices, or LCD displays. Instead, they provide industrial-style input and output ports for connecting sensors and actuators. For more information, see the section “Industrial Process Controllers.”

A. DSC devices
B. Remote telemetry units
C. SCADA devices
D. Programmable logic controllers
