| Abstract: | MODBUS protocol has powerful data transmutability,delectability and real time processing capability,so it had become a communication language that application widely in auto- control field at present. This article introduces the design and development of the real-time communication through MODBUS protocol between HONEYWELL TPS system and SIEMENS PLC, recommend the characteristic of MODBUS protocol and use course,it makes to be comparatively detailed introduction to hardware of two systems,software configuration and debug. This system has been run steadily and reliably,it offers valuable reference for the using and popularize. |
