See this Bell Telephone Laboratories advertisement
from a 1952 issue of Radio & Television News magazine. It was one of
the earliest instances of SCADA, used to monitor and control remote relay stations
for its transcontinental microwave links.
Supervisory control and data acquisition (SCADA) is used, as the name suggests,
to monitor and control processes. My personal exposure to SCADA was while working
for the Potomac Edison power company in Hagerstown, Maryland, as an engineer. for
a short time right after graduation from college. At the time, all of the substations
and big switching stations either had, or were being outfitted with SCADA capabilities.
Functions ranged from simple monitoring the positions of circuit breakers and power
(voltage & current), to changing transformer tap ratios and operating switches.
Remote communications were handled via telephone model or power line carrier. Some
work was being done with wireless. Of course SCADA implementations have much wider
and varied uses than power distribution. Vast manufacturing installation and industrial
process are handled through SCADA.
