ABSTRACT:
Selectively seizable operating units (e.g. switches, lines or coders), forming part of different groups A, B etc. of identical units, are monitored to detect any change of state in a unit of, say, group A followed within a predetermined test period by a change of state of a unit of, say, group B. From the occurrence of the second transition, and in the absence of a switchover of any other unit of either group during the test period, an operative association is recognized between the two units in which these transitions were consecutively detected. The monitoring of all the units under surveillance is carried out in time-division sequence by cyclically scanned sensors individually assigned to them.
