Abstract
Recently, there is a desire to accurately share information concerning the presence or absence and content of a change in a setting parameter value. Provided is a change detection apparatus including a parameter acquiring section that acquires a value of at least one setting parameter of a field device, at predetermined time intervals; a change detecting section that detects whether the value of the setting parameter has been changed; and a change information output section that outputs change information, in response to a change in the value of the setting parameter having been detected.
Claims14
A change detection apparatus comprising:
- a parameter acquiring section that acquires a value of at least one setting parameter of a field device, at predetermined time intervals;
- a change detecting section that detects whether the value of the setting parameter has been changed;
- and
- a change information output section that outputs change information, in response to a change in the value of the setting parameter having been detected.
A change detection method comprising:
- acquiring a value of at least one setting parameter of a field device, at predetermined time intervals;
- detecting whether the value of the setting parameter has been changed;
- and
- outputting change information, in response to a change in the value of the setting parameter having been detected.
A recording medium storing thereon a program that causes a computer to function as:
- a parameter acquiring section that acquires a value of at least one setting parameter of a field device, at predetermined time intervals;
- a change detecting section that detects whether the value of the setting parameter has been changed;
- and
- a change information output section that outputs change information, in response to a change in the value of the setting parameter having been detected.
