摘要
针对EDPF-NT+分散控制系统(distributed control system,DCS)与第三方通讯的问题,提出了在系统中利用虚拟控制器建立任务,与第三方或多方系统进行基于Modbus RTU、Modbus TCP协议的通讯,并解决了通讯过程中经常遇到的问题。
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.
