A control system which controls a control target includes a controller connected to one or more devices through a network, and an information processing apparatus connected to the controller. The controller includes an event log containing an event having occurred during a control operation, and network statistical information containing statistical information associated with data transmission on the network. The information processing apparatus includes a factor estimation unit that provides an interactive user interface in accordance with selection of an anomaly phenomenon registered in the event log.

There is provided an information processing apparatus capable of identifying the cause of a data transfer error. The information processing apparatus for identifying a cause of occurrence of a data transfer error in data communication with a device includes: an error detection unit that detects occurrence of a data transfer error; a recording unit that records the number of detections of the data transfer error per a unit time; and an identification unit that identifies, on the basis of a trend in the number of detections of the data transfer error per the unit time, whether the cause of occurrence of the data transfer error is influence of noise or a hardware fault.
