Device configuration management apparatus, system, and program

A device configuration management system comprising:

• a field device configuration management apparatus;
• a data collection apparatus;
• and
• a field device,
• wherein the data collection apparatus is a computer that collects data transmitted from the field device,
• wherein the field device configuration management apparatus comprises:
• a logical node information storage that stores logical node information about logical nodes that can be associated with the field device and a particular location, the logical node information including, for each of the logical nodes, a logical node identification (ID) for identifying the logical node, a device ID for identifying the field device, and location information which is information for identifying the particular location;
• a network information storage that stores network information as a set of information about an edge connecting two logical nodes;
• a history storage that stores a history about the logical node information stored in the logical node information storage;
• and
• at least one processor configured to:
• perform processing for updating at least one of the device ID and the location information with regard to a particular logical node in the logical node information stored in the logical node information storage;
• acquire a first device ID associated with a first logical node ID in the logical node information storage and a second device ID associated with the first logical node ID in the history storage;
• and
• acquire a first measurement value measured by a first field device identified by the first device ID and a second measurement value measured by a second field device identified by the second device ID in a case where the first field device is replaced with the second field device, and to combine the first measurement value and the second measurement value in a time axis direction;
• and
• a device information storage that stores device information about the field device in association with the device ID,
• wherein the at least one processor of the field device configuration management apparatus is configured to execute a user interface function that provides, to an external terminal apparatus, a user interface that allows generating, updating, or deleting data stored in the logical node information storage, the network information storage, and the device information storage,
• wherein when the user interface function receives a particular signal by communication from the field device, the at least one processor provides, to the external terminal apparatus, a user interface that highlights information about the field device which is a transmission source of the particular signal on a display screen of the external terminal apparatus,
• wherein when the field device detects a trigger, the field device is configured to transmit the particular signal to the user interface function of the field device configuration management apparatus, and
• wherein the data collection apparatus receives data used for process control from the field device and stores the data received from the field device as time series data in association with the logical node.

A non-transitory computer-readable recording medium storing a program which, when executed by a computer, causes the computer to at least:

• perform processing for updating at least one of a device identifier (ID) and location information with regard to a particular logical node in logical node information stored in the logical node information storage that stores logical node information about logical nodes that can be associated with a field device and a particular location, the logical node information including, for each of the logical nodes, a logical node identification (ID) for identifying the logical node, a device ID for identifying the field device, and location information which is information for identifying the particular location;
• acquire a first device ID associated with a first logical node ID from the logical node information storage and a second device ID associated with the first logical node ID from a history storage that stores a history about the logical node information stored in the logical node information storage;
• and
• acquire a first measurement value measured by a first field device identified by the first device ID and a second measurement value measured by a second field device identified by the second device ID in a case where the first field device is replaced with the second field device, and to combine the first measurement value and the second measurement value in a time axis direction,
• wherein a data collection apparatus receives data used for process control from the field device and stores the data received from the field device as time series data in association with the logical node.
