Abstract:
A method of inhibiting the normal operating mode of a plurality of nodes logically connected to an electrical control device, said method comprising the steps of:tracking, in a memory, the status of each of the plurality of nodes as being either on or off; placing a first node of said plurality of nodes in the off state; communicating to said electrical control device a status message indicating that said first node has been placed in the off state; inhibiting said electrical control device, in response to said status message, from activating an electrical load connected thereto until each of said plurality of nodes is removed from the off state; removing power from the electrical load using the electrical control device responding to the status message; and updating, in the memory, the tracked status of each of the plurality of nodes as each node changes between on and off states.
