ABSTRACT:
Reestablishing connections when a block/device at one end is re-initialized. The data elements necessary for reestablishing a connection at both ends may be stored in a third device. When a block/device at one end is re-initialized, additional data elements necessary for reestablishing connection may be received from the re-initialized block, and all the data elements may be used to re-establish the connection. In an embodiment implemented in the context of a control system, a supervisory control station stores image of the various intermediate objects used in both end devices (at which ends of a connection terminate), receives parameters which identify changes when an end device is re-initialized, and makes changes to the stored intermediate objects. The changed objects are downloaded to the respective end devices to reestablish the connection.
