Abstract:
An Input/Output device comprising:an input/output port; programmable signal conditioning and signal control circuitry for receiving both discrete and analog signals, for scaling said received signals to a predetermined voltage range, for determining signal type for each of said received signals, and for controlling input/output circuitry of said programmable signal conditioning and control circuitry for accessing input signals and generating output signals, said input/output circuitry including a plurality of registers; conversion circuitry for receiving said output signals and converting said output signals from analog to digital to enable said output signals to be digitally processed, said conversion circuitry further receiving digitally processed signals, converting said digitally processed signals to analog signals, and transmitting said analog signals as input signals to said programmable signal conditioning and signal control circuitry; and bus interface logic circuitry for transferring information to and from said input/output port; and wherein reading said registers accesses said digitally processed signals and writing to said registers generates said output signals to be digitally processed.
