These research and development activities resulted in the introduction of the first fully computerized SCADA system in 1974. The system included a minicomputer-based master station with a standard, user configurable software package (SUPERCOMPILER II) and a microprocessor-based intelligent RTU (Quindett V). This was also the first application of intelligent RTUs as a protocol emulator where the RTU is installed in a foreign system and did not communicate with its native protocol. In this particular case, the Quindett V’s were installed in a General Electric SCADA system utilizing the GETAC protocol.
