Abstract: An automation device for process automation, with a server containing one or more process automation variables, wherein the server is configured to receive read and/or write requests from a client in communication with the automation device for at least one variable. The automation device adapted to: specify the time period between two read requests for the same read request variable and/or between two write requests for the same write request variable; specify a sampling time for the read or write request variable as a function of the specified time period; and enable read access to the read request variable in the address space of the server at the respective sampling time, independently of future read requests and/or to prepare write access to the write request variable in the address space of the server at the respective sampling time, independent of the previous write request.

Abstract: An automation system for process automation including at least one automation device which has at least one fieldbus interface for connection to a bus for transmitting process data, an arithmetic unit, a digital data memory and a data interface for transmitting program-flow-related event data; and an analysis device connected to the at least one automation device. The automation device is set up to run one or more computer programs with the aid of the arithmetic unit and to capture program flow events occurring during the running of the at least one computer program and to store them together with current time information as program-flow-related event data in the digital data memory, and wherein the arithmetic unit of the automation device is set up to continuously send the program-flow-related event data stored in the digital data memory to the analysis device connected via the data interface.

Abstract: An automation device, having an input for receiving input signals and/or an output for outputting output signals of a process, and an electronic data processing unit, which is adapted to run an application program during operation of the automation device and to process data contained in the input and/or output signals by means of a program function, characterized in that in a digital program memory, a plurality of program functions is stored separately to the application program, which are each uniquely addressable via a function pointer, wherein during operation of the automation device, based on a predetermined function selection, the application program is configured to determine the function pointer of the program function corresponding to the predetermined function selection from a functions reference list stored in a digital data memory and, by means of the determined function pointer, to run the program function corresponding to the predetermined function selection for processing the data contained in
