Abstract: The invention relates to an automated system in which a targeted search may be made for connecting terminals without having to actuate a load connected thereto. For this purpose, the automated system has a communication network, a programmable control unit, and at least one modular bus subscriber which are connected to the communication network. The modular bus subscriber has multiple groups of connecting elements, a display element being associated with each group of connecting elements. An evaluation and control unit is also provided which actuates at least one selected display element in response to signaling information originating from the programmable control unit. The programmable control unit is designed to provide this type of signaling information.

Abstract: A temperature measurement module having position compensation provided for connection to at least one thermocouple includes a temperature-dependent resistor, via which a first temperature of a reference point of the thermocouple can be detected as a resistance voltage. The temperature measurement module includes an evaluation circuit which allows a first temperature value of a measurement point to be determined via the resistance voltage and a thermoelectric voltage of the thermocouple. The temperature measurement module includes a compensation mechanism which modifies the first temperature value depending on the installation position of the temperature measurement module so that thermal influences of the evaluation circuit, which have a thermal effect on at least one of the reference point or the measurement point depending on position, are compensated at least in part.
