1. A method for controlling a plurality of network-type actuator modules connected to a main controller in a multi-drop scheme, the method comprising:

  • transferring, by the main controller, a single instruction packet including a plurality of IDs to the actuator modules; and

    in response to receipt of the single instruction packet,transferring, by the actuator modules, each status packet corresponding to the actuator modules to the main controller, the each status packet being transferred corresponding to each of the plurality of IDs and in a sequence order of each of the plurality IDs, the sequence order being indicated by the single instruction packet,wherein the plurality of IDs include a preceding ID and a subsequent ID, and the actuator modules corresponding to the subsequent ID in the instruction packet transfer a second status packet after the actuator modules corresponding to the preceding ID have transferred a first status packet, whereinthe first and second status packets are sent in order, and transfer of the first status packet of the preceding ID is monitored, and the second status packet is sent as soon as detection of the first status packet of the preceding ID being transferred, and whereina response delay between the first packet and the second packet, which is a return delay time, is removed to shorten the return delay time.
