    Abstract: The transmission of data via a differential bus by means of balanced signals is not only reliable, but also offers the advantage that in the event of various single faults, i.e. faults concerning only one of the two lines or faults where the two lines of the differential bus are short-circuited, data transmission is still possible, be it with a reduced reliability. To this end, both lines are connected to a number of comparators which have different threshold values so that the nature of a fault occurring can be determined and, in dependence thereon, the comparator output can be determined wherefrom the recovered data signal must be derived.

    Abstract: Generally speaking, steep signal edges are required for the processing of digital signals; however, notably externally supplied signals which are conducted, for example, via long cables are liable to have comparatively flat signal edges. By selecting appropriate switching thresholds, delays between an input signal and an output signal of a circuit can be minimized. The circuit selects the first switching threshold at a low value of the input signal and switches the first threshold value to a second, higher threshold value when the input signal exceeds a further, higher threshold value. Thus, an output signal is generated comparatively quickly after the beginning of the positive-going or negative-going edge of the input signal. This can be realized by switching over the switching threshold of a comparator or by utilizing two comparators. Switching over to the various switching thresholds, or the various comparators, is provided by a further control circuit which may also be driven by the comparators themselves. A particularly high insensitivity to interference is achieved when use is made of two comparators which themselves are constructed as Schmitt triggers.

    Abstract: Power and data are both transmitted over a single transmission line to which a power source and a number of stations are connected. A bipolar AC voltage is supplied to the line by the power source, the half cycle pulses of one polarity being used for supply of power only, while transmission of data is achieved by modulation exclusively of the half cycle pulses of the other polarity. High power is supplied to the stations by providing pulses of the one polarity at a low ohmic level. Only low power is required for modulation for the purpose of data transmission, and so the pulses of the other polarity are supplied at a relatively high ohmic level. Thus, only two conductors are required, one of which can be replaced by the system ground in the simplest case. If three conductors are provided, it is possible to achieve improved tolerance of defects in a conductor. At least parts of the system are maintained in operation, in the event of a short-circuit, by providing separation units which automatically disconnect different segments of a short-circuited line and automatically reconnect them after the short-circuit has been eliminated.

    Abstract: A sub-net operation with increased availability and reduced power consumption is achieved in a bus system with a plurality of stations (10, 11, 12) which are coupled to one another via a system of conductors (13, 14). Each of the stations includes a transceiver (21) and a control unit (30). The stations are switched from a quiescent state to a standby state in response to the reception of a first wake-up signal and selected stations are switched to a normal operating state upon reception of a second wake-up signal, whereby stations are selected.

    Abstract: In a system for the transmission of logic levels via a bus the recessive level, being of higher impedance in comparison with the dominant level, is not adjusted by means of a resistor but by means of a termination arrangement with three break points in the current/voltage diagram. In the third quadrant of the current/voltage diagram this termination arrangement has a resistance which is higher than that of a lead terminated by means of a linear resistor. In the first quadrant the rise of the characteristic up to a voltage below a receiving threshold is steeper than in the case of termination by means of a resistor. Subsequently, in the first quadrant the characteristic is subject to a current limitation which is effective from a voltage below the receiving threshold to a value beyond the working point of the dominant driver. Beyond the working point of the dominant driver the current limitation is removed again, so that the rise is steeper than in the case of termination by means of a resistor. This termination arrangement optimizes the ratio of the value of the driver currents, and the associated radiation via the bus, to the speed at which a level is adjusted on the bus. Moreover, the tolerance in respect of ground offset is thus improved and also the resistance to radiation.

    Abstract: In an electronic system for the transmission of data between a plurality of stations the control signals and functions of the basic elements of power supply, watchdog and signal converter in each station are linked to one another so as to ensure that the number of possible modes of operation, taken for all the elements, is reduced to a number necessary for the corresponding task and thereby guarantees a more reliable operation. Moreover, the linkage leads to an optimum default behavior of the station with regard to application-specific power-saving and safety requirements, even when, for example, the malfunction of the microcontroller of the station persists.
