Abstract

There are provided a slave, a work machine, and a method for storing log information, which are capable of appropriately store the log information when a communication abnormality occurs such that communication cannot be kept between a master and the slave in an industrial network. The control section performs first storage processing storing the log information into a volatile storage section when a communication abnormality occurs such that communication with the master cannot be kept, communication abnormality determination processing for determining whether the communication abnormality has occurred, and second storage processing storing the log information into a non-volatile storage section by acquiring the log information from the volatile storage section, in response to a determination made in that the communication abnormality has occurred as a result of the communication abnormality determination processing.
