Abstract: An information processing system includes: a generator that generates a control flow graph from an abstract syntax tree corresponding to source code of a user program; a formulator that formulates an inter-variable dependence by searching a variable which depends upon a variable used in the user program based on the control flow graph; a search module that searches a variable deemed to be a fixed value in variables used in the user program; and an update module that updates the inter-variable dependence by reflecting the variable deemed to be a fixed value on the source code.

Abstract: An information processing device including a CPU and a memory storing a program. The CPU generates a plurality of cause-and-effect models between variables based on a relationship between a plurality of mechanisms in a production process of a production line, a dependency between a plurality of events associated with the plurality of mechanisms, or a control-based relationship between the plurality of mechanisms, obtains a result of abnormality detection in the production line, calculates a contribution ratio of a variable contributing to abnormality in the result of abnormality detection, and estimates an abnormality causal factor for at least one of the plurality of cause-and-effect models based on the calculated contribution ratio of the variable contributing to abnormality.

Abstract: An item for designating a time stamp accuracy is added to an inquiry syntax of a query. At the time of table coupling, a query designating the desired accuracy in the item is transmitted. This query is analyzed by a query purser, and individual queries are created for each database targeted for inquiry and transmitted. At the time of coupling acquired tables, the number of digits of the time stamps is adjusted to be the same in accordance with the designated accuracy, and the tables are coupled in chronological order of the time stamps.

Abstract: A controller includes a feature quantity generation unit that generates, from data associated with a control target, a feature quantity appropriate for detecting an abnormality in the control target, a machine learning unit that performs machine learning using the feature quantity, an abnormality detection unit that detects the abnormality based on an abnormality detection parameter determined from a learning result of the machine learning, and the feature quantity, an instruction unit that instructs the abnormality detection unit to detect the abnormality, and a data compression unit that compresses data about the feature quantity and provides the compressed data to the machine learning unit and the abnormality detection unit. The instruction unit transmits a request for detecting the abnormality to the abnormality detection unit. The abnormality detection unit detects the abnormality without returning a response to the request.

Abstract: Unauthorized installation of software is prevented even at a production site at which software cannot be installed through a communication line. The memory card stores: additional software including a software ID; a recording medium ID; and encrypted information generated by encrypting the software ID, using the recording medium ID as a key. The controller performs the steps of: obtaining the encrypted information from the memory card; obtaining the recording medium ID from the memory card; obtaining the software ID by decrypting the encrypted information, using the recording medium ID as a key; obtaining the software ID from the additional software, comparing the decrypted software ID and the software ID obtained from the additional software; and storing the additional software in the storage when the comparison is successful.

Abstract: To reduce the processing load of the control calculations run on a PLC while quickly providing data representing a state of control, a PLC for communicating data with an external device executes a user program to manage a controlled object. The user program executes a program that monitors data representing a state of control, which can be referenced or updated. When a monitoring condition is met, the monitoring program transmits a data message representing the state of control via a server to the external device using a PUSH-type protocol.
