<p>PURPOSE:To recover a destroyed condition even if the management control condition is destroyed in a power unit controller by providing a means storing system information being added at the time of transmitting a control indication from the power unit controller in a power unit to be controlled. CONSTITUTION:The power units to be controlled 2-5 which execute communication through an interface 14 with the power controller 1 connected through interfaces 11, 12 and 13 with respect to the hosts of a #1 system, a #2 system and a #3 system are provided. The power controller which adds information on the indicated system, transmits the control indication from the host-side to the power units to be controlled, and controls the control conditions of the power units to be controlled, and the storage means storing system information added when the control indication is transmitted from the power controller in the power units to be controlled are provided. Consequently, the control condition of the power units to be controlled devices is doubly managed in the power controller and the power unit to be controlled. Then, the management control conditions can immediately be recovered even if it occurs and it cannot affect an influence for subsequent control.</p> |
