  • Protocol for extended data transfer in scan-based industrial controller I/O system
    Patent number: 6662247
    Abstract: Extended low priority data is integrated into high priority I/O data in a scanned data transfer protocol using regular transmission fixed data blocks by allocating as little as a single word of the data block to the sequential transmission of this low priority data. Low priority data is buffered on both sides of this transmission to allow it to be transmitted over the course of many data block. As a result, the regular and predictable transfer of input and output data is not upset while allowing arbitrarily large low priority data to be sent at a relatively low data rate.
