Abstract
An input error detection device can detect an input error based on input values input in the past and the trend of values from the view point of the whole of a control program. In order to detect an error in inputting a value used to control a manufacturing machine, the input error detection device is provided with a histogram creation unit configured to create a histogram, based on a set of values used to control the manufacturing machine, and a determination unit configured, based on the histogram, to determine input errors of the values used to control the manufacturing machine.
