Claim Text:
1. A device information display apparatus comprising: a communication unit configured to communicate with a field device; a display device configured to display parameters of the field device and values of the parameters acquired by communicating with the field device via the communication unit; a storage unit; a display control unit configured to associate first position information, which indicates a position of the device information display apparatus at which the values of the parameters displayed on the display device are acquired, and reproduction information, which is for reproducing the parameters that have been modified based on a first operation instruction for the parameters displayed on the display device, and to store the first position information and the reproduction information into the storage unit; a position information acquisition unit configured to acquire second position information that indicates a current position of the device information display apparatus and provide the second position information to the display control unit; and a setting unit configured to change the values of the parameters set to the field device based on a second operation instruction for the values of the parameters, wherein the display control unit is configured to: calculate a distance between positions indicated by the first position information stored in the storage unit and the second position information, identify at least one field device associated with the first position information in which the distance between the positions indicted by the first position information and the second position information is no greater than a prescribed reference distance, read out the reproduction information associated with the identified at least one field device from the storage unit, to reproduce the parameters on the display device using the reproductions information associated with the identified at least one field device, and display the parameters, which have been modified based on the first operation instruction for the parameters, on the display device, to associate the second position information acquired by the position information acquisition unit with the reproduction information for reproducing the modified parameters, and to store the second position information as the first position information and the reproduction information for reproducing the modified parameters into the storage unit, wherein the display control unit is configured to be capable of displaying a two-dimensional map showing a relationship between the position indicated by the first position information stored in the storage unit and the position indicated by the second position information acquired in the position information acquisition unit.
