  • Computation apparatus with coordination of the access to an internal memory and operating method
    Patent number: 9361212
    Abstract: A programmable logic controller (PLC) with changing memory access times is intended to interact with a subordinate system, i.e., a discontinuous virtualized system, wherein a computation apparatus is provided, in which the PLC is implemented and in which the system that is subordinate to the PLC with respect to an operation to access the memory access is implemented. A memory to which a component of the PLC has access is integrated in the PLC. Also implemented in the computation apparatus is a proxy device that coordinates access to the memory of the PLC by the subordinate system such that simultaneous access by the component of the PLC has priority over access by the subordinate system and it is thus possible to ensure that the PLC always complies with a predefined cycle time of the PLC.
