Field device information display apparatus and method that display information based on proximity
First Claim
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, anddisplay 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.

Abstract
A device information display apparatus displaying device information acquired by communicating with a field device may include a storage unit that associates and stores first position information indicating a position at which the device information displayed on the display device is acquired and reproduction information for reproducing display content of the display device that has been modified based on an operation instruction for the device information displayed on the display device; a position information acquisition unit that acquires second position information indicating a current position of the device information display apparatus; and a display control unit that calculates a distance between positions indicated by the first position information and the second position information, wherein if the distance is no greater than a prescribed reference distance, the reproduced information corresponding to the first position information is used to reproduce the display content of the display device on the display device.
