ABSTRACT:
A high speed programmable logic controller is taught. Briefly stated a Programmable Logic Controller having memory, a microprocessor and a Co-Processor are operatively interconnected using a Harvard style architecture therefore having separate data and instruction busses. The Co-Processor acts as a Boolean Processor and is therefore able to simultaneously perform instruction fetches and executions thereby resulting in substantially increased overall speed of the PLC and therefore allowing for fast process control.
