Abstract:

A microprocessor-based control/status monitoring arrangement allows for replacement of mechanical memory, cam-operated control board switches, such as used in controlling and monitoring the operation of a conventional electrical power generating station. The control/status monitoring arrangement includes and operator input device, such as a keyboard or "touch screen" cathode ray tube (CRT), to permit operator entries, as well as a video display to provide visual information relating to the operating system, e. g. , power generating station, being monitored and controlled. The control/status monitoring arrangement not only offers the advantages of the prior art cam-operated mechanical switches in a solid state system with programming flexibility, but also provides additional equipment status indications and controls, e. g. , Lockout, Tripped, Auto Started, etc. , and special interlocks to ensure operating safety.
