Method for Synchronous Execution of Programs in a Redundant Automation System

摘要

A method for synchronous execution of programs in a redundant automation system comprising at least two subsystems, wherein at least one request for execution of one of the programs is taken as a basis for starting a scheduling pass, and during this scheduling pass a decision is taken as to whether this one program is executed on each of the subsystems. Suitable measures are proposed which allow all programs a fair and deterministic share of the program execution based on their priorities.
