A trace assistance device includes a memory section, an acquisition section, and an output section. The memory section stores a manipulation log and an operation log. When a predetermined trigger event occurs during the board work, the acquisition section acquires at least one target manipulation history related to the trigger event, a target operation history associated with the target manipulation history, a comparison manipulation history that is the same as or similar to the target manipulation history, and a comparison operation history associated with the comparison manipulation history from the manipulation log and the operation log stored in the memory device. The output section is configured to output an operation of the board production line recorded in the target operation history and an operation of the board production line recorded in the comparison operation history, which are acquired by the acquisition section, in a comparable manner.

A trace data acquisition system, comprising: a plurality of industrial machines configured to sequentially process an object; and circuitry configured to: determine whether one of the plurality of industrial machines has satisfied a specific condition; and request another industrial machine to acquire trace data when the one of the plurality of industrial machines is determined to have satisfied the specific condition.

An abnormality determination apparatus of the present invention acquires state data from work equipment provided with an attaching part to which a plural kinds of work parts are attached in a replaceable manner, identifies the kind of a work part attached to the attaching part, sets, corresponding to the identified kind of the work part, abnormality determination data for determining an abnormality of the work equipment, acquires, from among state data acquired from the work equipment, state data of a time when the identified kind of the work part was being attached, and compares the acquired state data with the set abnormality determination data to determine an abnormality of the work equipment.

A log collecting device enabling a grasp of an actuation status based on event logs without a restriction regarding a memory, and an industrial robot and an electric-powered press including the same are provided. A log collecting device 1 is provided on, for example, an industrial robot and an electric-powered press, stores an event log 11 indicating details of an event occurred at an apparatus in a volatile memory 3, creates the collection data 12 that is a collection of the event logs 11, stores this collection data 12 in the volatile memory 3, and deletes the event logs 11 collected as the collection data 12 from the volatile memory 3.
