Each of communication control units that perform communication using EtherNet/IP executes data processing for reading of a state value stored in a state value management unit and/or writing of the state value to the state value management unit on the basis of first setting information, and executes exchange of frame data including the state value with the communication control unit of a communication partner on the basis of second setting information. If one communication control unit has failed the data processing, this information processing device displays, on a display, the first setting information of the one communication control unit and the second setting information of the communication control unit in a comparable manner, and if a pair of communication control units have failed exchange of frame data, the information processing device displays, on the display, the second setting information of one communication control unit and connection information in a comparable manner.

A data extracting apparatus comprises: a processor configured to execute a program; and a storage device configured to store the program, the data extracting apparatus being configured to access: configuration information that defines a work environment including a group of sensors; and a data extraction rule, which is used for extraction from the configuration information, and is defined for each event that indicates one of a change and abnormality of the work environment, and the processor being configured to execute: detection processing of detecting a specific event based on sensor data from the group of sensors; extraction processing of extracting related data related to the specific event from specific configuration information corresponding to an acquisition time of the sensor data out of the configuration information, based on a specific data extraction rule corresponding to the specific event; and output processing of outputting the related data.

A programmable logic controller executes an SFC program including a plurality of blocks, each including a step indicating an operation output and a transition indicating a transition condition. The programmable logic controller includes an SFC device data collecting unit for collecting device data of a device included in an active step for each scan at the time when the SFC program is executed, an SFC device data storing unit for storing the data collected by the SFC device data collecting unit, and an SFC device data outputting unit for outputting the data stored in the SFC device data storing unit to a memory card as a file for each of the steps or the blocks.

A display system includes a display device in production equipment. The display device includes a control unit, a display unit, a storage unit, and an input unit. The storage unit stores: schematic illustration data that represent a schematic illustration of the production equipment; and causal relationship model data in which one or more cause elements of one or more abnormalities that can occur in the production equipment are selected from driving means for driving the production equipment and monitoring means for monitoring the production, and the cause elements and the relationships between the cause elements are represented as a causal relationship model. The control unit displays the schematic illustration and the causal relationship model on the display unit such that the causal relationship model is superimposed on the schematic illustration so as to correspond to the schematic illustration.
