Summary:In order to achieve a program trace device applicable even to a distributed system including an embedded apparatus or computer which is scarce in the capacity of a memory area, a master execution means (100) is provided with an ID addition unit (120) for adding a message ID pre-assigned for each content to be processed; an inter-CPU communication count addition unit (130) for adding a predetermined initial value of an inter-CPU communication count; an error state detection unit (140) for detecting that an error has occurred in processing until reception by the master execution means (100) by matching the inter-CPU communication count in a received message with a predetermined value of a case in which normal processing has been performed; and a trace data storage unit (150) for extracting trace data from a message by way of a detection result of the error state detection unit (140) and storing thereof. A slave execution means (200) comprises an inter-CPU communication count update unit (260) for updating the i
