Abstract: A control and communication system including a number of automation units which are adapted to process signals in function plans within the automation unit and which are connected in the same level to a common communication bus for providing a peer-to-peer communication between the automation units, further includes an engineering unit being connected to the communication bus and being adapted to provide functions allowing at least one automation unit to exchange signals to a function plan which is attributed to another automation unit.

Abstract: There is described a method for determining the processing sequence of components of a function plan for a sequentially operating automation system. Each component is allocated a component code in a reversible unambiguous manner and, while the components have a signal input and output connection, these should be applicable to a number of various function plans and thus minimize the reaction time of an automation system to process signals. The above is achieved, whereby the signal path in the function plan commences at an initial component in a recursive procedure in the forward direction and returns in the backward direction.

Abstract: A method for performing online program changes on an automation system is provided. New program parts are loaded into a CPU of the automation system, while a user program is currently running, in order to provide a new user program. In order to avoid overloading of the CPU, switching is made to the new user program only after it is determined, by monitoring of the first processing of all the program cycles, that the CPU has not been overloaded.

Abstract: The invention proposes a method and a control apparatus for storing a first data block containing data for controlling a technical process in a first memory area of an automation apparatus. In this case, a second data block containing data for controlling the technical process is stored in a second memory area of the automation apparatus. The first data block and the second data block are subdivided into a plurality of data areas. At least one data area which is part of the first data block is supplied to the automation apparatus and stored in the first memory area. Furthermore, at least one data area which is both part of the first data block and art of the second data block is copied from the second memory area into the first memory area. A corresponding automation apparatus is also proposed.

Abstract: A system providing control and communication is provided including at least one automation unit being adapted to run an operation program, and an engineering unit being adapted to modify the operation program, the engineering unit including a code-configurator, which is adapted to project automation functions of the operation program in the form of at least one configured data structure and to modify the configured data structure, the at least one automation unit including an interpreter framework, which is adapted to include a catalogue of necessary automation functions of the operation program and an empty data structure, the interpreter framework being further adapted to interpret the modified configured data structure and to provide a modified operation program on the basis of the automation functions of the catalogue and the modified configured data structure.

Abstract: According to the invention, during continuous operation of an automation system, one type of structural component is initially modified by a projection tool in the surroundings of the projection, independently of the start of operation of the structural component and a characteristic of the type is maintained in a constant manner. The instance the structural component is replaced in the function plan by the modified structural component and the structural modifications are correspondingly recorded. The exchanged structural component is transmitted into the automation system, parallel to the continuous operation of the automation system and without repercussions thereon. The uninterrupted switching to the configuration takes into account the exchanged structural component such that the modified and exchanged structural component is activated in the automation system.
