摘要:
The present disclosure concerns a state monitoring or diagnostics system, and also a method for monitoring the state of devices or for diagnosing devices, in particular for overvoltage protection devices, as well as a method for transmitting measured values. Each of the devices comprises a functional component to be monitored and a monitoring and transmitting apparatus, wherein the monitoring and transmitting apparatus consists solely of a resonator circuit made of passive electrical components with no microchip, in particular with no RFID transponder. The information to be interrogated resides in the resonant frequency of the resonator circuit.

The invention relates to a method for operating an Ethernet-capable field-bus device that can be connected to an arbitrary Ethernet-based communications unit by means of which data is transmitted using a predetermined communications protocol stack. For this purpose, a network management channel is initially established between the Ethernet-capable field-bus device (50) and a management device (30) connected to the communications network (20) using an Ethernet-based network management protocol that is installed both in the field-bus device (50) and also in the management device (30). The communications protocol stack installed in the management device (20) is then transmitted using the predetermined network management protocol from the management device (30) to the Ethernet-capable field-bus device (50), where it is stored. In this way, it is guaranteed that useful data can be transmitted using the communications protocol stack from and to the field-bus device (50) via the Ethernet-based communications network (20).

The invention relates to a method for parameterizing operating means connected to a data transmission medium. In this case, for at least several of the connected operating means, in each case, a device description will be stored in a central facility, each device description containing at least one function and the parameter set belonging thereto. In addition, a list of several predefined device functions will be stored in memory, for which the corresponding parameter set will be assigned each time to the operating means that support the device function. If a device function is selected, then in response to the selected device function, at least one operating means that supports this device function will be parameterized.

A method and system are disclosed that secure data transmission in a communications system employed to control safety-relevant processes, through the provision of cooperating evaluators arranged in a shared manner in communications stations in order to evaluate safety-oriented data in a simple and cost-effective way. In the disclosed method, a data report is transmitted from a first station, by means of a communications system designed for serial data transmission, to a second station and said data report is checked by means of a second evaluator arranged in the second station. Depending on the results of the check of the data report, an acknowledgement report is transmitted from the second station to the first station, which acknowledgement report likewise is checked by the evaluator arranged in the first station. Furthermore, the disclosed system carries out the method.
