A method and arrangement for commissioning an updated application for an industrial automation arrangement, wherein a first, existing application on a first controller and the updated application on a test device are executed in parallel, where local software (in particular a proxy service (proxy)) writes sensor data to the process image of a separate test device, where memory cells (e.g., I/O values, variables or registers) not yet belonging to the local process image of the test device are applied or allocated there, such that the 'external' data and values of the productive system (first controller) are available in the local process image of the test device, without needing to change the production version of the application or the version of the application to be tested, and where the output values of the updated application are tested; if successful, the updated application is cleared for operation.

The process control unit is configured to execute a plurality of control processes, wherein a first control process executed on the process control unit is configured such that there is no provision for direct exchange of process variables with a second control process, but rather this exchange takes place via an interposed association module. An association specification is used to ascertain the control process(es) to which the process variable needs to be handed over. One advantage includes the increased flexibility in the exchange of process variables, which now takes place in the individual control processes by an association module. Restarts of the process control unit and associated production losses advantageously become unnecessary. Additional resources in the process control unit or in an engineering system may be reduced or avoided. The decreased complexity means that the control systems and engineering systems are developed more easily and hence also more quickly.

A real-time automation device includes a real-time databus, and a memory device, wherein the databus is configured to transmit values associated with defined bus variables and configured to communicate a value associated with a bus variable from a bus variable source in accordance with a bus database via a databus to a bus variable receiver associated with the bus variable in accordance with the bus database such that, following transfer of the value from the bus variable source to the databus, the value is transferred within a predefined time period to the bus variable receiver, wherein the memory device also includes a software application which receives values associated with the bus variable from the databus or sends values associated with the bus variable to the databus, and wherein the automation device registers the software application as a bus variable receiver or as a bus variable source for the bus variables.
