Abstract: An apparatus system, including a programmed general purpose computer, for sensing the closed or opened state of large numbers of discrete points. The sensed points are placed in groups. System operation is initiated under control of the computer. Thereafter, the system interrogates each group of sensed points sequentially. During each group interrogation, all sensed points are first examined in parallel. If all sensed points are in a normal state, the following group is then interrogated. If any are in an off-normal state, each point in the group is scanned individually. An interrupt to the computer is then generated after which the computer takes action pursuant to stored error routines.

First Claim:
Show all 13 claims
We claim:     1. In a system for monitoring the status of discrete devices and transmitting status information to an external computer, the combination comprising:
  • a. a group of said discrete devices, each of said discrete devices being in (1) a normal state, or (2) an off-normal state;
  • b. means for generating an interrogation signal for initiating a determination of said states of said devices;
  • c. scanning means coupled to said generating means to receive said interrogation signal, said scanning means for scanning said states of all of said discrete devices in said group simultaneously, said scanning means including means for generating a first response signal dependent on said states of said discrete devices in said group;
  • d. means responsive to said first response signal for scanning each of said discrete devices individually when at least one of said devices in said group is in said off-normal state; and
  • e. means responsive to said individual scanning means for generating a second response signal to said computer in accordance with said state of each of said devices in said group only when at least one of said devices in said group is in said off-normal state, said computer for outputting predetermined signals to said discrete devices for control thereof responsive to said second response signal generation.
