Abstract
The I/O modules for an industrial control processor are connected together in a serial I/O ring. The processor performs an I/O scan sequence in which output data for the I/O modules is shifted serially from an output image table onto the I/O ring and input data from the I/O modules is pushed around the I/O ring and into the processor where it updates an input image table.
