Supervisory Control and Data Acquisition (SCADA)
Early on, these types of systems were built using proprietary hardware and software, operating in isolation without connections to other networks. operators had to reside in a centralized control room or command center because human-machine interfaces (HMIs) did not support remote access. Any information provided to personnel other than operators was delivered via reports, which often had a significant time lag. Once devices were connected to much larger networks, they became more complex and gained broad capabilities.
