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 bus system comprises a data line having a first channel with a first pair of wires and a second channel with a second pair of wires. The first channel connects a physical feed module interface to a physical consumer module interface and a first DC voltage source to a first consumer module DC voltage consumer, to transmit a first differential data signal between the feed module interface and the consumer module interface and a first direct current from the first DC voltage source to the first consumer module DC voltage consumer. The second channel connects the feed module interface to the consumer module interface and a second DC voltage source to a second consumer module DC voltage consumer, to transmit a second differential data signal between the feed module interface and the consumer module interface and a second direct current from the second DC voltage source to the second consumer module DC voltage consumer.

The first connection side has a rotatable first connection device. The second connection side has a second connection device fixed to the housing, with a rotation-compatible data transmission device for transmitting data signals along at least one transmission path between the first and second connection sides. The transmission path includes at least one wireless transmission sub-path for wireless transmission of data signals, and at least one wire-guided transmission sub-path for wire-guided transmission of data signals. The rotation-compatible data transmission device includes at least one first wireless transmission unit and at least one second wireless transmission unit, interconnected via the transmission path and arranged to wirelessly transmit and receive data signals along the wireless transmission sub-path. An industrial robot can have a plurality of such arm modules.

Abstract: An apparatus and a method for range extension for a combined data and power line are provided. Further, a bus system is provided. The design is based on a supply voltage that is transmitted via the combined data and power line being refreshed by a charge pump. Further, there may be provision, by way of example, for a data signal that is transmitted via the combined data and power line to be refreshed using the likewise transmitted supply voltage.

Abstract: An input/output module is provided for a bus system having a socket, the five contact cups of which each may comprise an electrical contact, and a measuring device for detecting a connector of a four-wire data cable. The measuring device can be configured to detect, when a connector is inserted into the socket, whether the connector comprises four or five electrical contact pins which are each plugged into one of the contact cups and are electrically connected to the respective electrical contact of the contact cups. The measuring device may be configured to close a first and a second switching device only when five electrical contact pins are detected in order to apply a respective supply voltage from two DC voltage supplies to the corresponding plugged contact pins of the connector plugged into the socket via the respective electrical contacts of the contact cups.

Abstract: A safety module for a secured drive control of an automated drive system is configured to receive encoder data sent from an encoder unit to a drive unit, based on an encoder protocol via a protocol active unit. The safety module is configured to forward the encoder data from the protocol active unit to a safety logic and a protocol passive unit, check the forwarded encoder data with the aid of the safety logic for correspondence with predetermined safety criteria relating to operation of a motor unit, and transmit the forwarded encoder data via the protocol passive unit to the drive unit, in respective data packets based on the encoder protocol. The safety module can stop operation of the motor unit with the aid of the safety logic, if the encoder data does not correspond to the predetermined safety criteria. A corresponding drive system and automation system are also provided.
