ABSTRACT:
An industrial controller I/O module includes on-board programming circuitry in the form of a microprocessor and associated memory, a first programmable logic circuit and a second programmable logic circuit connected through an isolation interface. The programmable logic circuits are programmed by the microprocessor on power up by reading configuration data from the PROM and writing it to the logic circuits to define their I/O circuit functions in controlling the I/O drives on a controlled machine or process.
