ABSTRACT:
Application interface software provides communication between a network of computer nodes and user applications of a host processor. Interpreters or gateways are used between the host processor and the network of computer nodes. The application interface software employs a redundancy routine to ensure host access of computer node data through the gateways. The redundancy routine changes access of computer node data from one gateway to a second gateway during times of dysfunctioning of the one gateway. The redundancy routine changes access in a manner which is transparent to the host processor. A database is employed to hold computer node data for direct access by the host processor. The redundancy routine ensures the latest computer node data values to be reflected in the database.
