An industrial control system for use in power generating plants, manufacturing plants, oil and gas processing plants, utility sub-stations, utility grid switching yards, and wind or fluid-flow turbine generating systems. A master controller such as a master control unit or turbine control unit (MCU or TCU) printed circuit board (PCB) is located in an enclosure. A plurality of input/output I/O subsystems is located at a remote points-of-control for the remote I/O subsystems. A plurality of serial analog, digital, or frequency input/output fiber optic communication ports is located at the master controller printed circuit board, one port for each of the I/O subsystems. Fiber-optic cables connect the fiber optic communication ports on the master controller printed circuit board to fiber optic communication ports on the I/O subsystems. Means are provided at the master controller to distribute serialized I/O signals to the remote I/O subsystems over the fiber-optic cables.
