ABSTRACT:
A control system for an electronic data processing system minimizes hardwiring and specialized components and circuits and provides bidirectional communication between a data processor within the data processing system and an operator via intermediary binary digital input and output words. A separate aspect is the provision of a master control panel configuration including means for receiving input and output elements having generalized identities, in conjunction with encoder and decoder means interposed in the circuitry and reducing the interconnections between the panel and the data processing system. The control system converts the status of selector switches and momentary switches to signals representing an intermediary input word. The data processor processs and interprets the signals representing the input word and generates appropriate system responses. The data processor also generates and processs intermediary output words having a selected format for controlling lamp displays and segmented elements generating numeric displays. Consequently, the panel and system have relatively few interconnections but the use of generalized terms permits input positions and output displays to have varying and selectable meanings, as determined by the data processing system itself. The interactive control system includes decoders and drivers which illuminate displays in response to the output words. Circuitry is reduced by using a single character numeric display register to control illumination of several numeric displays by sequentialy illuminating the numeric character displays at a flicker-free rate. Each numeric display is excited at a rate of 30 cycles per second, requiring the contents of the numeric display register to be changed at a cyclic rate of 240 cycles per second.
