| Abstract: | A network construction of the small distributed all digital field control system and its access control style of token passing combined with master-slave have been presented in this paper. The design of network com- munication protocol and network maintenance technique are also studied. In accordance with the token passing transmission and data frame communication,a effective software control method in time domain is proposed. |
