An abnormality determination system includes motor control circuitry that controls a motor of a motor-driven machine based on a motor control command, and compares operation data of the motor obtained in controlling the motor with reference data stored in a storage to determine whether the motor driven machine has an operation abnormality, upper-level control circuitry that transmits the motor control command to the motor control circuitry, and data transceiver circuitry that transmits and receives the reference data and the operation data to and from the motor control circuitry.

A temperature detector (201) of an input unit (200) acquires a temperature of the input unit (200). A temperature detector (301) of an output unit (300) acquires a temperature of the output unit (300). When the temperature of the input unit (200) or the output unit (300) satisfies a preset condition, an input/output manager (101) of the CPU unit (100) controls passage/blockage of a signal from the detector (901) to the input unit (200) or a signal from the output unit (300) to a control target device (902) in accordance with preset content of signal input/output restriction.

A program display control unit performs a display process of displaying first time-series data corresponding to a specified time specified by a display time specification unit, on a first sequence program stored in a first device, which is displayed in a second display section, and another display process of displaying second time-series data acquired from a second device of multiple devices, corresponding to the specified time specified by the display time specification unit, on a second sequence program stored in the second device, which is displayed in a third display section.

A distributed control system includes: a plurality of control devices; a process IO master device shared by the control devices and including an output authority table and an output data memory having areas for storing data outputted from the control devices; and a plurality of process IO modules connected to the process IO master device and each connected to a sensor/actuator, wherein the output authority table provides an authority that determines the control device of which output data is to be adopted, for each of addresses corresponding to the actuators.

The present disclosure provides a method and a system for automatically configuring an I/O port. The method applied to a central processor includes: receiving request information from a controlled device, the request information carrying a type of a signal required by the controlled device, and sending, according to the type of the signal, a configuration instruction to a control device, and instructing the control device to configure the I/O port according to the configuration instruction. The controlled device is directly connected to the central processing unit, or the controlled device is connected to the central processor by means of the control device. Thus, a communication link between the central processing unit and the controlled device can be established, so that the central processing unit can automatically generate a configuration instruction according to the type of the signal required by the controlled device, so as to instruct the control device to configure the I/O port. Accordingly, the I/O port is automatically configured, thereby realizing unmanned operation, and avoiding a risk of manual misoperation.

The program generation apparatus includes a terminal detection unit for detecting position information including a position of a first terminal of an input/output apparatus to which an electrical wiring is connected. A display control unit displays, on a display part, a control program and position information of the first terminal detected by the terminal detection unit. The operation detection unit detects a symbol indicating the device specified by the operator. The setting unit allocates the position of the first terminal which is included in the position information of the first terminal to the symbol which is indicative of the device which has been detected by the operation detection unit.

Example implementations described herein are directed to a change over detection system and method. Such example implementations facilitate updating the information of the production line in an Internet of Things (IoT) system to the latest version. Through the example implementations described herein, device rearrangement in manufacturing field can thereby be detected.
