High Speed Data Interface for Personal Computers

       Described is a hardware/software implementation that
provides high-speed data link interface capabilities for personal
computers (PCs) incorporated with plant floor manufacturing
equipment.

      In prior art, interface capabilities for controlling plant
floor manufacturing equipment consisted of real-time interface
co-processor serial port communications architecture that did not
provide the high-speed requirements required for real-time
environments.

      The concept described herein provides a means of linking system
enabler programs, such as a distribution automation edition (DAE)
with real-time multi-kernel (RMK) software.  The net result is
VME-DAE interface (VDI) software that produces the high-speed data
link interface operation.

      Fig. 1 shows the basic hardware used to attain the high-speed
interface.  The VDI software runs in conjunction with real-time
multi-processing kernel (RMK) software to provide the interface link.
The concept is designed to operate with a multi-tasking operating
system so as to provide a communications manager for network and host
communications as well as database support.  The DAE is designed for
extensive communications support and operator interface.  The VDI
software is a modified logical device interface
procedure/communications protocol program which was developed to
convert generic data device management server commands to a format
recognized by th...
