Device information display apparatus, storage device storing device information display program, and device information display method
First Claim
1. A device information display apparatus comprising:
- a communication unit configured to communicate with a field device;
a tokenizer configured to acquire a device information of the field device, which is described in a format of an EDDL file or an XML file, to create a DD file, the DD file being customized based on the EDDL file or the XML file;
a DD analysis unit configured to read the DD file and access the device information of the field device;
a display unit configured to display the accessed device information on a display device;
an analysis unit configured to analyze a reference frequency and a setting frequency of the device information displayed on the display device;
a display parameter management unit and a display parameter changing unit configured to manage and change the accessed device information to be displayed on the display device, the changing being performed based on operation instructions received from an input device;
a display parameter generation unit configured to generate a display parameter definition file for prescribing the accessed device information to be displayed on the display device, the generating being performed based on the device information changed by the display parameter management unit and the display parameter changing unit; and
a display parameter switching unit configured to switch the accessed device information to be displayed on the display device, the switching being performed based on the display parameter definition file generated by the display parameter generation unit.
