Special Internal Relays
Special internal relays M8000 through M8177 are used for controlling the CPU operation and communication and for indicating the
CPU statuses. All special internal relays cannot be used as destinations of advanced instructions.
Internal relays M300 through M335 are used to read input device statuses of the IOREF (I/O refresh) instruction.
