The present disclosure relates to a provisioning server for providing a secured control parameter for multi-channel control of a machine using a plurality of distributed controls that output single-channel control parameters. The provisioning server includes a first communication interface configured to receive a plurality of single-channel control parameters from the plurality of distributed controls, a processor configured to compare the received single-channel control parameters and output one of the received control parameters as the secured control parameter if a threshold number of the single-channel control parameters are in agreement, and a second communication interface configured to send the secured control parameter to the machine via a communication network.

Techniques for providing a secured control parameter for multi-channel control of a machine

An electrical interface module (IM) has a memory device MEM) for storing data and an integrated interface (IO) that provides data to an external reading device (RW). The electrical interface module (IM) contains a carrier () on which the memory device (MEM) and the integrated interface (IO) are arranged, the electrical interface module (IM) can exchange data and/or power with other electrical interface modules (IM) in the vicinity via the integrated interface, and adjacent electrical interface modules (IM) form a logical data bus via the integrated NFC interfaces, which can be addressed and/or controlled by at least one head module or a master module with a higher control and/or monitoring device.

Electrical interface module

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.

Method and system for secure data transmission

The invention provides a method for operation of an automation system having at least one bus system connected to at least one subscriber, and having a central control system. The method includes parameterizing and/or programming the at least one bus subscriber by the central control device, identifying an interruption in the connection to the control device by the at least one bus subscriber, and controlling at least one output of the at least one bus subscriber as a function of the parameterizing and/or the programming upon identification of the interruption in the connection. The invention also provides an automation system which is suitable for carrying out the method.
