Glossary
Real Time Feedback
Real Time Feedback requires Instantaneous (or nearly instantaneous) communication of sensor data to process operators or equipment. This enables rapid or automated adjustments that keep production processes operating within quality parameters.
Real Time System
A Real Time System is a computer system designed to receive, process, and respond to data within a time frame set by outside events. Many industrial control systems are real time systems.
The events which establish the required time frame can be both on the input side of the computer (for example, sense the position of an elevator) and on the output side (apply the brakes, announce the floor, open the doors).
