An information processing device determines, based on a preset threshold, whether the production index belongs to either a first section or a second section contained in one maintenance cycle of the member, wherein a change in the production index is larger in the second section than in the first section. The information processing device executes at least one of first processing in which the production index determined to belong to the first section is used and second processing in which the production index determined to belong to the second section is used.

Information processing device and information processing method

A control system includes a control device that repeatedly performs a series of pieces of processing including I/O refresh processing and program execution processing. The control system includes: a first obtainment unit that obtains a first sample value group collected by repeatedly performing the I/O refresh processing in a first control period; a second obtainment unit that obtains a second sample value group collected by repeatedly performing the I/O refresh processing in a second control period longer than the first control period; a determination unit that determines whether a first frequency component in the first sample value group and a second frequency component in the second sample value group are substantially identical to each other; and a change unit that changes the first control period to the second control period under a condition that the first frequency component and the second frequency component are substantially identical to each other.

Control system and control device

A network system is provided with at least one terminal device, a control device that controls a machine, and a server device that receives data including at least one of image data and audio data from at least one of the control device and the terminal device that are connected via a network, and distributes the received data to a different device from the device that transmitted the data. The control device is provided with a controller that executes a control operation, and a communication unit that transmits data indicating an operational state of the machine that is controlled to the server device. The terminal device includes a display unit that displays the operational state of the machine controlled by the control device together with a state of another terminal device connected to the server device.

Network system and control device

A program control apparatus ensuring real time response by ensuring execution of a process exclusively without locking the system includes a unit responsive to an application program interface call from a thread which interface requesting start of detection of presence/absence of a context switching, for setting a flag indicating presence/absence of a context switching to a state corresponding to absence of a context switching, a unit for setting, after said flag is set to the state corresponding to absence of a context switching and a scheduler switches context, the flag to a state corresponding to presence of a context switching, and a unit responsive to an application program interface call from the thread, which interface requesting termination of detection of presence/absence of a context switching, returning a value corresponding to the state of the flag to the thread.
