Abstract
PURPOSE: To easily and rapidly perform trouble diagnosis of the circuitry composed of a multitude of control elements by constituting in such a way that gradual memory of signals in the part required to diagnose the trouble is being done with constant changes of memorizing places in a memory unit until the trouble spot is found on the basis of its content.
CONSTITUTION: An equipment 101 which is put to be an object for making diagnosis has for example contacts 103, 105, 107 put ON when a relay 109 behaves, whereas when contacts 119, 121 are put ON, a relay 123 will have a part to behave. Signals X1, X2, X3, X8 from intermedidate points of these contacts are taken together with signals X4WX7 through a buffer 127 into a microcomputer 129. The microcomputer continues the memory every time as the signals X1WX8 go on changing. At the time when a trouble happens, its memory content is tapped on a teleprinter 135, which is used for making analysis of the trouble spot
