Patent ID: 7742492

Claim:
A system that communicates data from a network to an input/output module, comprising: an adapter module that receives data, the adapter module includes: a network data component that receives data from the network including, an output data component that receives standard data; and an output expansion data component that receives cyclic extended data transfer data, including a lower half and an upper half of an attribute index number, and a Distributed bus data component that receives data from the network data component, the Distributed bus data component includes, an output data component that receives standard data from the output component contained in the network data component; and an output expansion data component that receives cyclic extended data transfer data from the output expansion data component contained in the network data component, wherein the lower half of the attribute index number is received, echoed to the extended data transfer module and verified and the upper half of the attribute index number is received, echoed to the extended data transfer module and verified, a Distributed extended data transfer module that receives data from the adapter module via the Distributed bus data component, wherein standard output data is communicated utilizing a standard data scan, and expansion output data is communicated utilizing a cyclic extended data transfer protocol.
