Abstract: A plug-in module. The plug-in module includes a module housing, a heat-dissipating device, and an electrical component arranged on a printed circuit board. The heat-dissipating device has, on a surface facing the electrical component, an internal thermal interface to thermally couple the electrical component to the heat-dissipating device. The heat-dissipating device has, on a surface facing away from the electrical component, an external thermal interface to thermally couple at least one heat-dissipating device to an external heat sink. The external thermal interface includes a thermally conductive elastic compensating element connected to the heat-dissipating device and designed to be compressed during formation of the external thermal interface.

Abstract: A method of commissioning a field device in an industrial system network includes: a) connecting a field device to an industrial system network; c) providing information about the field device, the information including functional information for the field device; d) utilizing the functional information for the field device to retrieve information relating to a role of the field device in an automation application; f) utilizing capability information relating to a field device type of the field device and the information relating to the role of the field device in the automation application to retrieve a parameter set for the field device for operation in the automation application; and g) downloading the parameter set to the field device.

Abstract: In one aspect, a solar inverter which can be connected to at least one photovoltaic generator at the input end and to a power system at the output end is provided. The solar inverter includes an inverter module, an electronic control unit at least for diagnosing an inverter module, and a bus interface for technically connecting the electronic control unit to a communication bus. The electronic control unit cyclically outputs a piece of status information of the solar inverter on the communication bus, and outputs an error message on the communication bus, cyclically reads status information of other solar inverters that are connected to the communication bus, and outputs an error message on the communication bus in case at least one expected additional piece of status information fails to be output. Whereby, the need for a separate monitoring unit is eliminated.
