Abstract:
A slave device is equipped with: a parameter setting portion for setting different values according to the content of commands sent from a master device, as parameter values for detecting anomalies; and an anomaly detecting portion for detecting anomalies by comparing the time corresponding to a parameter value that has been set by the parameter setting portion and the measured time of a process carried out in response to a command.
