Abstract: An analysis device according to one aspect of the present invention supplies a definition for a dependency relation between an input parameter and an output parameter of a standard function, which cannot be derived in a dependency analysis of a control program, the definition being supplied by use of function structure information which is external information. In other words, an analysis device according to this configuration identifies a dependency relation between an input parameter and an output parameter of the standard function on the basis of function structure information that defines a dependency relation between the input parameter and the output parameter of the standard function. Therefore, the dependency relation between the input and the output of a standard function becomes clear, so the dependency relations between a plurality of device variables that mediate the standard function can be identified.

Abstract: A display system provided in production equipment having driving means and monitoring means with controllable features includes a control unit, a display unit, and a storage unit. The control unit obtains a feature output over time from at least one among the driving means and the monitoring means, and causes the storage unit to store the feature; constructs, in each prescribed time, a causal relationship model that indicates a causal factor selected from among the driving means and the monitoring means for at least one abnormality that can occur in the production equipment and that also indicates the relationship between causal factors on the basis of the obtained feature; and displays, on the display unit, a plurality of causal relationship models constructed in a plurality of times.

Abstract: A control apparatus for controlling a production or manufacturing apparatus that performs processing for sequentially producing an item to be produced through units arranged in a line, includes: a physical quantity acquirer that acquires a physical quantity representing a state of processing in a unit subjected to monitoring for each cycle, the cycle being defined as unit processing time of processing performed by each unit; an abnormality determiner that determines occurrence of an abnormality in the unit, based on the physical quantity or a feature value extracted from the physical quantity; and a control instructor that specifies, when it is determined that an abnormality occurs in the unit, a cycle during which a downstream unit performs processing on an item to be produced that is affected by the abnormality, and perform control so that abnormality handling processing is performed as processing in the specified cycle by the downstream unit.

Abstract: 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.

Abstract: A display system is provided in production equipment that has driving means and monitoring means, having controllable features. The display system includes a control unit, a display unit, a storage unit, and an input unit. The storage unit stores: the features output over time from one or more of the driving means and the monitoring means; and causal relationship model data in which one or more causal factors of one or more abnormalities that can occur in the production equipment are selected from among the driving means and the monitoring means and expressed as a causal relationship model in association with a relationship between the causal factors. The control unit displays, on the display unit, the causal factors of the individual abnormalities, the one or more features corresponding to the causal factors, and changes over time in the features.
