ABSTRACT:
A device for acquiring the maximum value (or the minimum value) of a multiplicity of measured values, having a multiplicity of measuring points for acquiring the measured values, an a data line for transmitting data values between the measuring points, at least one of the measuring points having a comparator for comparing a data value received on the data line with its own measured value, and being configured to transmit its own measured value on the data line only if said measured value is not smaller than the data value, wherein the data line is a serial line for transmitting the data value in the form of successive bits of decreasing significance, wherein the comparator is a serial comparator which compares the received bits of the data value with the identically significant bits of its own measured value, and wherein the measuring point is configured to transmit each bit of its own measured value which is detected as being larger than the corresponding received bit, until a comparison reveals that the bit of its own measured value is smaller than that of the received data value, and to then shut down the transmission of its own data value.
