Abstract

PURPOSE:To store the number of a large quantity of input signals for a long time, by storing only data for a change of a signal to be measured and reproducing this data periodically by a timer. CONSTITUTION:The use signal of a sequence control device 7 is taken into a microcomputer 2 in a sequence analyzing device 1 as a signal to be measured. In respect to taking-in of the signal to the computer 2, an interrupt signal (s) is generated when a state change of the signal to be measured is detected by a signal change detecting circuit 5, and the time of this state change and the state of the signal to be measured are stored in a storage device 3. Stored data is reproduced periodically by a timer and is outputted while having the time interval of the signal change equal to that at the storage time or expanded or shortened. A recording device 4 records the reproduced otput of the state change. An operating circuit 6 selects the time interval of the periodic timer and selects one of the recording device 4, a device 7, and a simulating device 8 as the output object.
