Mixed I/O Architectures
An application might readily justify a dual processor and dual I/O for some field
circuits, but not for all. It is easy and economical to configure one controller to
provide a solution. Consider a dual processor system that needs 16 inputs and 16
outputs, half of which must be duplicated and half of which can be simplex. The
requirement would be fulfilled by a controller architecture like this.
