An automation network comprises at least one master subscriber, at least one switch, and at least one subscriber. The master subscriber comprises master ports, the switch comprises switching ports, and the subscriber comprises ports, each comprising a transmitter and a receiver. The master subscriber is configured to output first and second telegrams to first and second switching ports via first and second master ports and first and second master communication paths. The switch is configured to forward the first telegram to a first port of a subscriber via a first communication path, and to forward the second telegram to a second port of a subscriber via a second communication path. In error mode, the switch and the subscriber are configured to return the first telegram to the master subscriber via the first master port, and/or to return the second telegram to the master subscriber via the second master port.

Provided is an information processing device including at least one processor, the at least one processor executing a first obtaining process for obtaining accessory equipment data transmitted from each of pieces of accessory equipment included in an accessory equipment group, a first converting process for converting the accessory equipment data, which has been obtained in the first obtaining process, into a particular format, and a first providing process for providing, to main equipment, the accessory equipment data whose format has been converted in the first converting process.

There has been desired a technology for performing a publishing setting of a variable to an external device more easily. A development assistance device provides a development tool configured to develop a user program for controlling a controller. The user program includes at least one variable belonging to a predetermined namespace. The development tool is configured to accept, for the namespace, a publishing setting for causing the controller to determine whether to publish the variable belonging to the namespace to an external device that is communicatively connected to the controller. A communication interface transfers the user program and the publishing setting to the controller on the basis of acceptance of transfer operation of the user program by the development tool.

In a master device (control device) that employs a configuration list, setup change is performed easily without requiring a complicated operation with respect to a partial change in the configuration of a slave-side system on a slave side. A control unit (11) of a control device (10) is configured to perform communication for inquiring about device information to an address in an active configuration list through a communication unit (12), and determine to be abnormal when the result of the communication with respect to a common portion of a slave-side system (20) is different from the device information in the active configuration list.

A control system includes a control unit, a transmission unit, an application execution unit, and an arbitration unit that arbitrates a data set exchanged between the transmission unit and the application execution unit. The arbitration means includes a first acquisition unit that acquires information about pieces of process data managed by the control unit, a second acquisition unit that acquires information about an application executed by the application execution unit, a determination unit that determines process data to be included in a data set based on the information about the pieces of process data acquired by the first acquisition unit and the information about the application executed acquired by the second acquisition unit, and a notification unit that notifies each of the transmission unit and the application execution unit of a content of the process data to be included in the data set determined by the determination unit.

Various systems and methods for implementing a software defined industrial system are described herein. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. In response to a node failing, a module may be redeployed to a replacement node. In an example, self-descriptive control applications and software modules are provided in the context of orchestratable distributed systems. The self-descriptive control applications may be executed by an orchestrator or like control device and use a module manifest to generate a control system application. For example, an edge control node of the industrial system may include a system on a chip including a microcontroller (MCU) to convert IO data. The system on a chip includes a central processing unit (CPU) in an initial inactive state, which may be changed to an activated state in response an activation signal.

A control system includes a control device, an information processing device, a grouper, and a generator. The control device executes a control program controlling a control target while managing process data of the control program. The control device transmits one or more types of data sets storing a part of the process data according to a communication setting. The information processing device executes one or more applications using the process data by using the one or more types of data sets. The grouper allocates the process data designated to be used in the one or more applications to one or more groups. The generator generates the communication setting for the control device such that the process data allocated to the group are stored in one data set and transmitted for each of the groups grouped by the grouper according to an allocation result.

A control system includes a controller, a transmission unit, an application executing unit, and a management unit. The controller executes a control program controlling a control target, and manages pieces of process data referred to or updated in the control program. The transmission unit transmits data sets including values of the pieces of process data managed by the controller, each of the data sets including one or more process data values. The application execution unit executes one or more applications using the value of the process data included in the data set transmitted by the transmission unit. The management unit determines a data set validating transmission in the data sets transmittable by the transmission unit according to the application executed by the application execution unit.

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.
