Abstract
A data communications arrangement for a distributed processor control system having a number of stations which can send and receive control data, includes a communications processor at each station effective for controlling the flow of control data over a serial communications bus. The communications processor is coupled to a dual ported memory device along with a functional processor which is effective for carrying out the actual operations of the process. The communications control processor is further effective for assembling frames of control data according to a predetermined arrangement which gives a timing preference to a first category of data over a second category of data. The assembled frame of control data will then include all of the first category of data and, with time remaining from a timing goal, will include a portion of the second category of data.
