Abstract: A monitoring method includes monitoring variables that change over time and are continuously measured during repeated executions of a dynamic process. The measurement data include training data in a training period and monitoring data measured subsequently to the training period. Vectors are continuously determined based on the measurement data, the vector components of which comprise respective rates of change of the measured values of the individual measured variables determined for a series of successive points in time on the basis of the measurement data, wherein the points in time of each series cover a time window of a duration and the time windows of successive vectors are shifted. The vectors are stored as a reference cluster. The vectors are compared with the reference cluster. An anomaly is determined when a vector is outside the reference cluster.

Abstract: A converter circuit includes a current interface with a control input, with a current signal output and a current output. The converter circuit includes a micro-processor with a measuring signal input for the digital measuring signal, with a current signal input connected to the current signal output of the current interface, and with a control output connected to the control input of the current interface. The current interface lets the signal current flow through the current output and simultaneously adjust both the amperage to a stationary amperage level corresponding to a control value currently applied to the control input, and to output a sequence of current values at the current signal output.

Abstract: A converter circuit serves to transform a digital measuring signal representing the chronological sequence of a periodically changing physical and/or chemical measurand into an analogue measure value signal dependent on the digital measuring signal with a signal current, an amperage of which represents a measuring value for the measurand.

In addition, the converter circuit comprises a micro-processor with a measuring signal input for the digital measuring signal, with a current signal input connected to the current signal output of the current interface, and with a control output connected to the control input of the current interface.
