    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: An automation system has a plurality of subscribers including a first master unit, first distributor, second master unit, second distributor, and at least another subscriber unit. First and second transmitting/receiving devices of the first and second distributor are connected via a ring-shaped data bus. In a first mode, the first distributor forwards telegrams received from the first master unit to the first transmitting/receiving device, and forwards telegrams received by the second transmitting/receiving device to the first master unit. The second distributor also forwards first telegrams received by the first transmitting/receiving device to the second transmitting/receiving device. In a second mode, the second distributor forwards telegrams received by the second master unit to the second transmitting/receiving device, and the second distributor forwards telegrams received by the first transmitting/receiving device to the second master unit. The first distributor also forwards telegrams received by the second transmitting/receiving device to the first transmitting/receiving device.

    Abstract: A communications network having a master subscriber M and at least one slave subscriber. At least one distribution node CU1, CU2, CU3, CU4 is provided which has a plurality of input/output interfaces, each of which is connected to a network segment, the master subscriber M arranged in a first network segment M1 and the slave subscriber arranged in a second network segment S1, S2, S3, S4, S5. Data is exchanged between the master subscriber M and the slave subscriber in the form of telegrams initiated by the master subscriber. The telegrams to be sent from the slave subscriber to the master subscriber are each assigned control data containing a forwarding time information when the corresponding telegram is to be output from the distribution node via the input/output interface in the direction of the first network segment comprising the master subscriber, the forwarding time information determined by the master subscriber M.

    Abstract: Hybrid plug connectors are provided for connecting different electronic modules to insulators arranged in an outer casing and for receiving a power conductor transmitting a power supply and a shielded data conductor for data transmission for transmitting signals/data of an industrial bus, such as ISA, ethernet or similar, wherein the power conductor has at least two power lines and the data conductor has at least one data line, wherein the power lines and the data lines are guided in contact parts designed as plugs or sockets and can be coupled via these contacts parts, and wherein the outer casings of the pair-type hybrid plug connectors can be joined inside one another for interlocking coupling. The insulator arranged in each of the plug connectors can be arranged in a shield housing as a contact carrier receiving arrangement, the shield housing accommodating a contact carrier, which carries forward the data line(s) designed as plug sockets or plug pins in a shielded manner in the plug connector, and wherein the coupleable contacts form a shape-encoded interlocking connection in the plugged-in state of the connection.

    IPC: H04L12/40

    Abstract: A communications network comprises a plurality of participants. A first participant transmits a message repeating sequence of N≥2 successive messages to a second participant. An action which can be performed by the second participant is assigned to each message in the sequence. The first participant begins to transmit one of the N messages at N successive transmission times T_I (I=0, . . . , N−1). Each of the N messages contains a field defining a waiting time assigned to the respective message W_I=T_(N−1)−T_I+ΔW_I (I=0, . . . ,N−1), where ΔW_I is a non-negative tolerance time. The second participant selects one message from among the messages in the sequence which are successfully received by the second participant as a useful message, measures a time elapsed since reception of the useful message, and performs the action assigned to the useful message when the elapsed time has reached the assigned waiting time.

    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.
