ABSTRACT:
The present exemplary embodiment relates to industrial machine control and corresponding communication protocols. In one embodiment, the machine control communication protocol is Distributed I/O that has Extended Data Transfer (EDT) capability. It finds particular application with expanding the underutilized bandwidth of the EDT to gather/send secondary input and output data within a control system. In one aspect, a system communicates data from a network to an input/output module. An adapter module receives data. The adapter module includes a network data component that receives data from a network including an output data component that receives standard data and an output expansion data component that receives cyclic EDT data. A Distributed bus data component receives data from the network data component. A Distributed extended data transfer (EDT) module 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 EDT protocol.
