Abstract of the Disclosure A method and circuitry for communicating both byte transfer I/O data and file transfer I/O data to an individual I/O module through an equipment chassis backplane in a programmable controller. The byte transfer data is real time I/O data representing the status of I/O devices on an industrial machine or process. The file transfer data includes fault diagnostic data concerning conditions of the I/O devices in addition to their ON or OFF state. The circuitry is integrated into a single integrated circuit. The methods and circuitry are applicable to two different modes of addressing, one mode being used by earlier programmable controller processors and adapters and the other mode being used by newly developed processors and adapters.
