    摘要： A safety control unit includes: a memory; a computation control part; and an input and output unit for connecting the computation control part to a safety input device and an output device to be safely controlled. A system program includes a data refresh program for executing a data refresh of safety control data of the safety input device and the output device and the control data of the memory via the input and output unit. If the computation control part receives a change of a control program, the computation control part stops executing the control program. The computation control part executes the change of the control program while executing a part of the system program including the data refresh. The computation control part resumes executing the control program.

    摘要： A control device adopting a virtualization technique is provided. The control device includes: a real-time operating system (OS) executed using a hardware resource; a general purpose operating system (OS) executed using the hardware resource and operating independently of the real-time OS; and a hypervisor for managing the hardware resource allocated to the real-time OS and the general purpose OS. The control device includes: a file sharing server function operating on the general purpose OS to reserve a part of a storage device as a storage area and share at least one part of the reserved storage area set by a user with another device; a function operating on the real-time OS to participate in the file sharing server function as a client through the hypervisor; and a function operating on the real-time OS to periodically monitor whether a shared area provided by the file sharing server function is accessible.

    摘要： A technique for facilitating debugging in a user program which operates by cooperation of a PLC and another system in a control system including a controller and another system. A CPU unit has a communication interface, executes a user program, calls DB connection service in accordance with an instruction included in the user program, and generates a statement to access a database device. In the DB connection service, operation is performed while switching a first mode and a second mode. In the first mode, a statement according to an access instruction is generated, the generated statement is transmitted to a database system, and a result of a response is sent to the user program. In the second mode, without transmitting the statement to the database device, a result of execution corresponding to the statement is sent to the user program.

    摘要： A controller, such as a PLC, stores a task execution condition management table that indicates execution conditions for tasks and executes programs periodically in accordance with the execution conditions for the tasks. The controller provides a setting instruction for modifying the execution conditions for the tasks. A user enters the setting instruction in a user program by using a support device, for example. The controller updates the task execution condition management table with regard to a task associated with the instruction by executing the instruction for modifying the execution conditions for the tasks, including priorities of the tasks and cycles of the tasks, contained in the user program, and executes the programs in accordance with the updated execution conditions for the tasks.

    摘要： A control system easily adjusts devices. In a control system, an input unit included in a PLC system obtains actual sampling data. An output unit outputs an output signal based on output instruction data including a designated output timing and a designated output signal value. A task execution unit included in a controller repeatedly executes a task in a predetermined period. A sampling unit obtains variable sampling data. A same time-series data generation unit included in a development support apparatus generates same time-series data. A same time-series data display unit displays the same time-series data on the same time axis.

    摘要： 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.

    摘要： 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.

    摘要： A controller continues to operate in a stable manner after program modification. A controller repeatedly executes a task A and a task B in cycles. The controller includes a RAM and a task control program. The RAM stores a fixed time set longer than an actual execution time of the task A as an execution time for the task A. The task control program executes the tasks A and B, and executes the task A by using the fixed time.
