  • Average values for example arithmetic or geometric ones, can be used as statistical methods which lead to such a value.
  • a quantile for example median, can advantageously be provided from a series of such signals.
  • Several such quantiles are then stored in the information fields X_VAL_1, ..X_VAL_N.
  • several signals x 1 , .. x n possibly after a preselection, can be stored directly in the information unit INF W in the fields X_VAL_1, ..X_VAL_N.
  • a further indicator is expediently stored in the field X_VAL_IND, for example the field X_VAL_IND can have a width of 8 bits, which means that 8 different states or indications can be specified directly.
  • the signals stored in the fields X_VAL_1, .., Y_VAL_AVG, etc. of an information unit are referred to as measured values.

In principle, a transfer is also carried out with a data carrier, for example a floppy disk or with a portable personal electronic device of the locomotive driver concerned, possible.
