A method operates a safety control in an automation network having a master subscriber which carries out the safety control, at least one first slave subscriber which is assigned a first safety integrity level, and at least one second slave subscriber which is assigned a second safety integrity level. The first safety integrity level and the second safety integrity level differ from each other. A first safety code determination method is assigned to the first slave subscriber and a second safety code determination method is assigned to the second slave subscriber. The first safety code determination method and the second safety code determination method differ from each other. The master subscriber and the first slave subscriber use the first safety code determination method for interchanging a safety data block. The master subscriber and the second slave subscriber use the second safety code determination method for interchanging a safety data block.

The invention relates to a half bridge for operating a load comprising a switching device having a high-side semiconductor switch (T1) and a low-side semiconductor switch (T2) which are serially connected to one another via one of the respective current connections thereof. A control port is associated with each semiconductor switch via its control connection, which according to a control signal switches the respective semiconductor switch to be conductive or to be inhibiting. The load can be connected between the high-side semiconductor switch and the low-side semiconductor switch and to a load relief device (L1, C1) which is connected to the switching device in order to collect current in a switching operation in the switching device. The invention further relates to a circuit arrangement having at least one half bridge.


The invention relates to a distribution node in an automation network, having at least two input/output interfaces for transmitting and receiving real-time-relevant and non-real-time-relevant data packets and a switching device which is connected to the two input/output interfaces. Furthermore, in the event that a non-real-time-relevant data packet is received, the switching device detects the length of the non-real-time-relevant data packet in order to ascertain the transmission duration, which is produced therefrom, for the non-real-time-relevant data packet. The switching device additionally detects the transmission pause duration remaining until the next real-time-relevant data packet is transmitted for an input/output interface at least if a respective input/output interface for a non-real-time-relevant data packet is provided as a transmission interface and is in the transmission-free state, and the switching device checks whether a non-real-time-relevant data packet is present with a transmission duration which maximally corresponds to the transmission pause duration for the input/output interface as the transmission interface in order to transmit the non-real-time-relevant data packet via the input/output interface in the event of a positive check result.

To operate a load a half bridge includes a switching device with a high-side semiconductor switch and a low-side semiconductor switch. The semiconductor switches are connected in series via their current terminals, and each semiconductor switch may be assigned, via its control terminal, a driving system that switches the respective semiconductor switch on or off according to a drive signal. The load is connectable between the high-side and low-side semiconductor switches. The half bridge may include a load relief device connected to the switching device, e.g., in order to collect energy during a switching process in the switching device. The half bridge can\include an energy recovery circuit configured to feed the energy collected by the load relief device, e.g., a current, to an energy storage device before a further energy collection, e.g., current collection, of the load relief device, during a further switching process in the switching device.

The invention relates to a drive device (615) comprising: an electric motor (601), wherein the b-side (605) of the electric motor (601) comprises a first receiving area (101) for a electronic power converter and a second receiving area (607) for additional electronic units, both receiving areas being thermally separated (301) from each other by means of a thermal isolation such that when the electric motor (601) is in operation, a first temperature range (609) can be formed in a first receiving area (101) and a second temperature range (613) can be formed in a second receiving area (607). A heat shield (401, 403) having a section (403) projecting into the first receiving area (101) is formed, said heat shield being decoupled from the first receiving area (101) by means of the thermal isolation (301), the projecting section (403) comprising a third receiving area for a position sensor (501).

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.

A distribution node for an automation network comprises at least two input/output interfaces for transmitting and receiving real-time-relevant and non-real-time-relevant data packets, and a switching device connected to the input/output interfaces. The switching device forwards data packets received via an input/output interface via a further input/output interface using a switching table, where the switching table contains at least a data packet identifier and a transmission time in a data transfer cycle for each real-time-relevant data packet. Inter alia, the switching device can detect a data packet identifier on reception of a real-time-relevant data packet, and output the real-time-relevant data packet at the transmission time allocated to the detected data packet identifier in the switching table via an input/output interface as a transmission interface.
