Method and system for providing time-critical control applications

Abstract

System and method for providing time-critical control applications via flow control components that are each loadable into and executable by a flow control environment formed via a server device, wherein the control applications each periodically determine, from periodically acquired measured and/or state variables, manipulated variables for a process to be controlled or regulated, a plurality of mutually redundant flow control components are executed in parallel with one another, the mutually redundant flow control components determine the manipulated variables for a respective process cycle that follows a respective acquisition time of the measured and/or state variables when a majority of the mutually redundant flow control components signal error-free presence of the measured and/or state variables for the respective acquisition time, where as an alternative or in addition, the determined manipulated variables are transmitted, together with a sequence number assigned to the respective process cycle, to actuators and/or control units.
