Claim 0:
1. A multidrop network system comprising N network devices, the N network devices including a master device and (N−1) slave device(s), each of the N network devices having an identification code as an identification in the multidrop network system and thus the N network devices having N identification codes in total, the N network devices earning transmission opportunities in turn according to the N identification codes in each round of data transmission of the multidrop network system, and each of the N network devices performing a count operation to generate a current count value, wherein:
the N is an integer greater than or equal to two;
when the identification code of a Kth device of the N network devices is the same as the current count value, the Kth device earns a Kth-device transmission opportunity of the transmission opportunities, in which the K is a positive integer not greater than the N; and
after earning the Kth-device transmission opportunity, the Kth device makes a determination of whether a cut-in signal from another network device is observed in a front duration of a predetermined time slot, and then determines whether to abandon or defer a right to start transmitting in a back duration of the predetermined time slot according to the determination.
