摘要： There is provided a technique for preventing unauthorized use of software downloaded to a controller. A controller includes: an obtaining unit that obtains, from an external device, software and first license information for the software; and a processor that executes the software. The software includes: a generation module that generates an execution right for the software from first unique information for uniquely identifying the controller or the external device; and a check module that generates second unique information from the execution right at a predetermined timing after the generation of the execution right, and that prohibits use of the software when the second unique information does not coincide with the first unique information.

摘要： A controller stores link information linking a predetermined event to a variable associated with the event. The controller stores first log information in association with time information into a memory in response to occurrence of the predetermined event. The first log information includes information about the event, and a current value of a predetermined variable associated with the event included in the link information. The controller stores second log information in association with time information into a memory in accordance with a predetermined period. The second log information includes information about a value of the predetermined variable. An information processing device obtains the link information from the controller, and displays information indicating the variable associated with an event indicated by the first log information onto the monitor-based on the link information and the second log information.

摘要： A controller allows easy synchronization between a plurality of control programs executed in parallel to control a plurality of motors. The control programs are executed cyclically in parallel in predetermined execution cycles. Timing data for synchronizing the execution timing of the control programs is transmitted and received between the control programs. After control program 1 is executed, an axis variable to be referred to by the control program 2 is copied from an execution area of the memory for the control program 1 into a buffer area for the control program 2.

摘要： A control unit includes: a memory; a computation control part; and an input and output unit for connecting the computation control part to a device of an (FA) system. A system program includes a data refresh program for executing a data refresh of data of the 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, and resumes executing the control 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 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.
