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. The present invention is adapted for integration with existing cam-operated mechanical switches and their replacement on a step-by-step basis and makes use of software timers to mimic the period an operator previously had to hold the prior art mechanical switches in a given position. The programmability of the control/status monitoring arrangement allows great flexibility in the manner in which status and control information is visually displayed.
