Abstract: A system includes a plurality of field devices electrically connected to a feed-in device configured to provide an electrical energy supply to the field devices. The feed-in device has a monitoring device configured to detect spark generation in the energy supply and, based on this, to switch off the electrical energy supply. The field devices each have an input terminal for connecting a supply line. At least one field device is configured for electrical energy supply to at least one subsequent field device, and for monitoring. The monitoring field device has at least one output terminal for connecting a further supply line, via which the electrical energy can be forwarded to the subsequent field device. The monitoring field device has a monitoring device configured to detect spark generation in the energy supply to the subsequent field device and, based on this, to switch off the electrical energy supply.

Abstract: A mediator comprises a mediator controller comprising an Industrial Ethernet protocol module, at least one Ethernet APL protocol module, and a translator module connected to the Industrial Ethernet protocol module and the at least one Ethernet APL protocol module. The Industrial Ethernet protocol module interprets Industrial Ethernet data provided via a first SPI interface and allocates Industrial Ethernet services. The at least one Ethernet APL protocol module interprets Ethernet APL data made available via a further SPI interface and allocates Ethernet APL services. The translator module connects the Industrial Ethernet services and the Ethernet APL services to one another and coordinates them in terms of time.

Abstract: A computer-implemented method is provided for generating a communication network between at least one OPC-UA client and at least one field device of an automation system. The method includes identifying at least one field device of the automation system via a communication gateway of the automation system in an identifying step, generating an OPC UA node set for the identified field device by the communication gateway in a generating step, and storing the OPC UA node set on an OPC UA server in a node set storing step. Related methods for data communication and data analysis are also described, along with a communication gateway and an automation system.

Abstract: A system includes a plurality of field devices electrically connected to a feed-in device configured to supply electrical energy. The feed-in device has a monitoring device to detect spark generation in the electrical energy supply, and, based on this, to switch off the supply. The field devices have a first section with an input terminal for connecting a supply line, and a second section. The electrical energy provided by the feed-in device can be supplied to the first section via the input terminal, and transmitted from the first section to the second section via an electrical energy supply connection. The second section has a terminal device with at least one output line terminal for connecting at least one output line to forward the electrical energy. The electrical energy supply connection has a power limiting device to limit the electrical power transmittable from the first section to the second section.
