A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The slaves each have identification information. The control apparatus executes a first instruction to set specified identification information to each of one or more specified slaves.

Control system and control apparatus

A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The control apparatus executes a first instruction to set specified identification information to a specified slave. In response to whether the specified identification information is successfully written, the control apparatus outputs information indicating whether a reboot of the specified slave is required.

The control apparatus includes executes a first instruction to set specified identification information to each of one or more specified slaves. The control apparatus outputs first error information indicating which slave that the setting of the identification information to which is failed, among the one or more specified slaves.

Provided is a control device comprising a communication management part and a user application processing part. The user application processing part is for detecting slave devices, which are communication targets of control data having been set using a setting tool, and the slave devices are connected to a filed bus. The communication management part is for managing the communication of the control data in accordance with a control cycle. The communication management part determines the control cycle using a pre-stored propagation delay time for each of the slave devices that are the communication targets of the control data.

Control device, control system, control method, and non-transitory storage medium storing control program

A control system which controls a control target includes a controller connected to one or more devices through a network, and an information processing apparatus connected to the controller. The controller includes an event log containing an event having occurred during a control operation, and network statistical information containing statistical information associated with data transmission on the network. The information processing apparatus includes a factor estimation unit that provides an interactive user interface in accordance with selection of an anomaly phenomenon registered in the event log.

Control system, information processing device, and anomaly factor estimation program

Provided is a control device comprising a communication management part, a computation part, and a result output part. The communication management part is for managing data communication using cyclic communication conforming to a prescribed communication cycle with respect to a field network. The computation part is for measuring a propagation delay time from received data corresponding to actual measurement data for a propagation delay having been transmitted to the field network, and detecting an operation state of the field network using the propagation delay time measurement result. The result output part is for outputting the result of the detection performed by the computation part.
