Abstract

Abstract: According to the communication problems between EDPF-NT+ distributed control system (DCS) and third-party, this paper proposed a effective strategy that established a communication to third-party or multiparty based on Modbus RTU protocol or Modbus TCP protocol in EDPF-NT+ system, which could effectively solve communication problems frequently encountered in EDPF-NT + system.

Key words: communication, virtual controller, DCS, Modbus, interface station, master station, slave station
