A communication processor apparatus (1), suitable for monitoring a sensor (18), particularly a safety-oriented sensor, for communication in a network is specified. The apparatus (1) comprises a processor unit (10) for processing incoming signals and for producing and/or providing outgoing signals and a code store (11), integrated in said processor unit, for providing a code for the processor unit (10). In this case, the code is in the code store (11) in encrypted form. To decrypt at least one portion of the code, an external decoder (12) is provided. This decoder (10) is supplied with an output signal (U1, U2) from the sensor (18), or with a voltage derived from this output signal (U1, U2), as a supply voltage. |
