摘要
本文介绍了 NETWORK 6000 DCS与工控机之间串行通讯的系统结构、硬件配置、通讯协议和软件编程方法。重点介绍了 Modbus通讯协议，给出了系统组态过程及主要通讯程序。这种通讯方式同样可以解决其他使用 MODBUS协议的设备（如支持该协议的 PLC控制器）之间通讯问题。
This paper introduces the hardware configuration of system structure， communication protocol and software programming between NETWORK 6000 DCS and industrial controller. The communication protocol of Modbus is described in detail， and the configuration procedure and complete communication program are given. This method can also solve the communication problem between other instruments with the protocol of Modbus.
