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.

A switch mode power supply unit having a plurality of output channels and a web Interface for connection to a communications network, where the switch mode power supply unit includes a real time Ethernet controller which is connected to a control of the switch mode power supply unit and is equipped as a web server such that, a plurality of operating parameters of the switch mode power supply unit can be set and/or displayed in real time via the web interface such that the switch mode power supply unit can he configured and monitored via the communications network, while ensuring that any changes to the configuration are immediately effective.

The invention is a system that facilitates integration of laser or dot peen marking systems into factory automation networks using the standard EtherNet/IP protocol. Built-in support for the EIP protocol greatly simplifies the PLC programming task, and lowers the cost of integrating the marking system into factory operations.

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

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 is configured by two-way communication conducted between a controller and a display terminal for displaying an operating state of the controller, and includes a processing time managing unit configured to measure time taken for processing pieces of data received from another end, and obtain from the other end and manage time taken on the other end for processing the pieces of data sent to the other end, and a congestion control unit configured to adjust a data sending amount to the other end per unit time based on the time taken for processing the pieces of data on the other end which are managed by the processing time managing unit.
