Auto Distribution of Tag Table in P2P Control System

摘要

In control system,tag table is like a dictionary mapping tagname to address. Therefore,applications on workstation may use tagname to access different data in system. Normally tag table generated by configuration software will transfer to other workstation in system manually after system configuration,which is inconvenient and fallible. The development of peer-to-peer (P2P) network technology and the realization of control system based on P2P network make the auto distribution of tag table possible. In this paper based on file sharing technology the presented method realizes the auto distribution of tag table.
