The present invention addresses the novel problem of protecting against threats that can arise as a result of the development of networked or intelligent control devices and control systems. This controller system includes: a control unit that executes a control operation for controlling a control target; and a security unit that is connected to the control unit and oversees and manages security functions for the controller system. The security unit includes a detection means that detects whether any unauthorized intrusion into the controller system has occurred. The control unit includes a command transmission means that transmits commands for changing the behavior of the detection means of the security unit.

Controller system

Provided is a management system for performing quality management on manufacturing equipment. A management system that includes: an acquisition component that acquires state information for manufacturing equipment that is subject to management; a determination component that, on the basis of the acquired state information, determines whether an event has occurred; a display component that displays both an image that schematically or realistically represents a manufacturing line included in the manufacturing equipment and, separated into the four perspectives Machine, Man, Material, and Method, indexes that indicate the likelihood that there is a factor that caused an event; and an output component that, when a specific event has occurred, outputs, in response to a user selection, analysis results for each of one or more factors belonging to each of the four perspectives, the analysis results indicating a likelihood of having caused the specific event that occurred.

Management system and non-transitory computer-readable recording medium

Provided is a management system associated with a manufacturing line including one or more facilities. Each of the facilities is configured to process each workpiece according to order information. The management system includes: a collecting means for collecting event information about a process that takes place in each of the facilities; a classifying means for classifying, on the basis of a generation source and content of each piece of event information, the event information collected by the collecting means, into sets of event information generated due to the same workpiece; a generation means for generating data which represents process circumstances for each workpiece on the basis of the event information belonging to each of the sets classified by the classifying means; and a visualizing means for visualizing process progression circumstances for each workpiece processed according to the order information, on the basis of the data generated by the generating means.

Management system and management method

Provided is a management system for performing quality management on production equipment. A management system that includes: an acquisition component that acquires status information for production equipment that is subject to management; a detection component that, on the basis of the acquired status information, detects the occurrence of some event; and a display component that displays, separated according to inclusion in the four perspectives Machine, Man, Material, and Method, a plurality of factors that could be presumed to have caused the detected event in a manner in which the contents thereof and a probability of having caused the event can be compared.

A control system configured to use a database and a data storage area includes a control device for controlling a process executed on an object; and an image processing device arranged in association with the control device for taking an image of the object and processing image data acquired from taking the image of the object. The control device and the image processing device may work independently or collaboratively to send the database at least one of an attribute value or results information, and designation information in association with each other for the same object, the attribute value managed by the control device and corresponding to any attribute defined in the database, the results information representing a process result from the image processing device, and the designation information specifying a storage destination in the data storage area for the image data acquired from taking an image of the object.

Control system, control device, image processing device, and control method

Provided is a technique enables programming, including that for database operations, without describing a SQL used to operate the database. A PLC () that can access a DBMS () stores a user program () and definition information (), the user program () including a structure type of variable, the definition information () indicating a definition of the structure type. The sequence command program () sequentially executes instructions in the user program () and invokes a DB access process program () in order to access the DBMS (). The DB access process program () reads the definition information () and, on the basis of the read definition information (), generates a SQL statement to be used when access to the DBMS () is made by execution of the user program (). The DB access process program () executes the generated SQL statement by transmitting the SQL statement to the DB server ().

Control device

A control system includes a programmable controller having a CPU unit that carries out cyclic operations of processes. An additional temporary user memory is provided in addition to a regular user memory. When an on-line editing of a user program is to be carried out, the program is stored in both memories and the program stored in the temporary memory is called by an instruction execution engine to be executed. After the on-line editing is completed on the user program stored in the user memory, the program execution is based on the edited user program stored in the user memory.
