Method for storing data in a memory in a distributed automation system and method for coupling and automation component to a distributed automation system

Abstract

Dynamic access is provided to automation resources, where, in a distributed automation system having a plurality of automation components, a first automation component searching for an automation resource sends a request to the automation system and, for this request, receives a response regarding availability of suitable automation resources from all automation components which it has been possible to reach, and then selects that automation component which has the suitable automation resource and uses the automation resource.

1 . A method for storing data in a memory in a distributed automation system having a plurality of automation components, each having access to a memory, the data initially being stored locally on a client automation component, comprising:
 sending a request from the client automation component to a plurality of the automation components other than the client automation component;   sending a response to the client automation component from each automation component receiving the request, the response containing information relating to the memory to which the respective automation component has access;   selecting a chosen memory at the client, based on the information contained in the response; and   sending the data from the client automation component to the automation component having access to the chosen memory, for data storage in the chosen memory.   
   
   
       2 . The method as claimed in  claim 1 , wherein
 the data is stored in the chosen memory, and   the data is stored together with a descriptor.   
   
   
       3 . The method as claimed in  claim 2 , wherein the descriptor refers to a location for the client automation component in the automation system.
