Abstract: A control system includes plural units. The plural units include a master unit connected to a bus and a slave unit connected to the bus, the slave unit communicating with the master unit via the bus. The master unit includes a nonvolatile memory that stores first security information as information to be concealed, and the slave unit includes a volatile memory. The slave unit receives the first security information from the master unit at a predetermined timing and stores the first security information in the volatile memory.

Abstract: A technique capable of efficiently performing debugging in a program and checking of soundness in a control system including a controller and a database system. A CPU unit has a communication interface for connection to a database device. The CPU unit executes a user program to call a DB connection service in accordance with an instruction included in the user program and generate a statement to access the database device. In the DB connection service, a statement according to an access instruction is generated, and the generated statement is transmitted to a database system. After that, information indicative of time until a response from the database system is received is acquired, and the acquired information is stored as a log into a memory. A support device acquires the information and displays it on a monitor.

Abstract: The present invention provides a technique for improving the reliability of access to a database system in a controller, such as a PLC. A PLC accessible to a database accesses a DB server in response to an event in which a user program calls a DB access processing program. The DB access processing program stores status information indicating a status of accesses to the DB server in a nonvolatile memory, in accordance with an instruction of the user program. When a power interruption occurs, the PLC can obtain a status of accesses to the DB server at the timing of the occurrence of the power interruption by referring to the status information. Then, the PLC, for example, re-sends a SQL sentence, depending on the access status.

Abstract: A control device determines, every control cycle, whether or not process values stored in a time-series manner satisfy a predetermined event condition. When the event condition is satisfied, the control device causes a chapter associated with the satisfied event condition to be stored in correspondence with time information that specifies the control cycle. The control device determines a target section with the time information in correspondence with a chapter that satisfies an extraction condition being defined as the reference, and extracts time-series data of the stored process values included in the determined target section.

Abstract: A control system for factory automation includes a first unit and a second unit each including a timer, a data line over which data containing a timer value indicated by the timer is exchanged between the first unit and the second unit, a signal line that electrically connects the first unit and the second unit, and an adjustment module connected to the signal line and the data line. The adjustment module acquires, when receiving a trigger signal over the signal line, the timer value over the data line and matches the timer of the second unit with the timer of the first unit based on the timer value acquired.
