COMMUNICATIONS CONTROL SYSTEM WITH A SERIAL COMMUNICATIONS INTERFACE AND A PARALLEL COMMUNICATIONS INTERFACE

摘要

A communications control system is disclosed that includes a serial communications interface and a parallel communications interface for coupling a plurality of input/output modules with a control module. The serial communications interface is configured for connecting the plurality of input/output modules to the control module in parallel to transmit information between the plurality of input/output modules and the control module, and the parallel communications interface is configured for separately connecting the plurality of input/output modules to the control module to transmit information between the plurality of input/output modules and the control module, and to transmit information between individual ones of the plurality of input/output modules. The serial communications interface may comprise a multidrop bus, and the parallel communications interface may comprise a cross switch.
