Title: DATA ANALYSIS DEVICE, METHOD, AND PROGRAM
Abstract:
In order to detect errors in a production system without major modification to the existing production system, this data analysis device has: a receiver that receives packets sent between a production control device and a production device; an analyzer that finds the type of data included in the received packet payload, from an IP address and port number included in a header for the received packet; a selector that, on the basis of the data type found by the analyzer, selects a syntax or rule corresponding to the data type; and a decision unit that determines that there is an error in the production system if the data included in the payload does not follow the syntax or rule corresponding to the data type.
