摘要： An access authority is set for each data referred to by a program. A control system includes a control unit that controls a control target, a storage unit that stores a program executed by the control unit and each access authority for each of data referred to by the program, and an input unit that receives an access request for any one of the data. Each access authority includes information about an operation that can be executed by a user having each authority. The control unit refers to each access authority based on acquisition of the access request for any one of the data from the input unit, and determines whether the user who transmits the access request has the access authority for the data for which the access is requested based on each access authority.

摘要： A control system includes an information processing device that communicates with a controller that controls a control target. The controller or the information processing device include a storage device that stores one or more SQL statements to be executed and an execution result the one or more SQL statements in association with each other as log data. The information processing device includes a display controller that displays on a display an SQL statement to be corrected that has an unsuccessful execution result; an operation unit that accepts a correction operation on the SQL statement and an execution operation; and a communication interface that sends an execution instruction to execute the corrected SQL statement to the controller upon receipt of the execution operation and to receive an execution result of the corrected SQL statement from the controller. The display controller displays an execution result of the corrected SQL statement.

摘要： A control system includes a database configured to hold one or more tables, and a control apparatus configured to execute a control program and access the database. The control system acquires a number of columns of a table and a data type of each column, the table being selected from among the one or more tables. The control system defines a structure that includes a number of members corresponding to the acquired number of columns and that is available in the control program. The control system determines a data type of each member of the structure in correspondence with the acquired data type of each column.

摘要： 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.

摘要： There is expected a technique for restricting a server function without affecting a driving machine in the case where memory usage is increased. A controller includes a memory, a program execution section controlling a driving machine in accordance with a control program, and an OPC-UA server communicating with an external machine. The OPC-UA server includes: a function execution section, executing a function utilizing a memory region on the memory in response to a request from the external machine; a monitoring section monitoring usage of the memory; and a restriction section, stopping the above function of the OPC-UA server based on the fact that the usage has exceeded a predetermined threshold.

摘要： The disclosure provides a control device including a memory storing address information and a server section communicating with the external machine serving as a destination of publishing the address information. The server section includes a determining section, a monitoring section, and an address managing section. The determining section determines priority levels of publishing variables included in a control program to the external machine in accordance with a predetermined rule. The monitoring section monitors free capacity of the memory. With respect to public variables for the external machine among the variables included in the control program, the address managing section adds logical addresses of the respective public variables to the address information in order of the publishing priority levels as long as the free capacity does not fall below a predetermined threshold.
