Abstract:
1. A measurement or protective device, comprising: a terminal for establishing a connection to a data bus; a control device configured to stipulate a measurement or protective mode of operation of the measurement or protective device, wherein the mode of operation may be changed externally via said terminal; said control device being configured to operate at least two software modules in parallel with one another and independently of one another, said software modules including an operating module configured to stipulate the measurement or protective mode of operation of the measurement or protective device, and at least one test module configured to perform test purposes; and said control device having at least one software interface to which said at least one test module can be coupled by software means externally via said terminal; wherein the measurement or protective device is connected to one or more measurement transducers, that produce phase-conductor-based samples which are transmitted to the measurement or protective device; wherein the control device is configured to downsample the samples by reducing the number of samples; and wherein the test module is configured to evaluate the received phase-conductor-based samples from the one or more measurement transducers directly without resorting to the reduced number of samples.
