In this paper an intelligent ultrasonic distance-measuring transducer integrating distance-measuring module based on the emission and receiving of ultrasonic with control module based on MSP430 series SCM and communication module based on protocol RS485 is put forward.

A system of remote monitoring and real-time data collection about the inverter which is based on 80C196MH is presented through RS485 communication protocol,the hard- ware design and software realization of this controlling system is introduced.

In this text,we introduce to use communication protocol of RS422/RS485.

Research on jacquard control based on communication protocols;

0 language． Also the circuit of hardware ,the communication protocols as well as the flow charts of software are proposed． Finally an application instance on the signal sampling and chromatographic data analysis system is introduced

The Realization of Process-control Communication Protocol and Its Intelligent Compression Function;

This paper analyzes two network communication protocol in industrial control field,and aiming for designing automatic control system of Xuzhou water treatment firm,it gives a king of typical design method which includes super-computer?PLC and industrial ethernet.

The paper discusses hardware equipments and communication protocol.

According to a pipeline project of Qingdao Petr-chemical Plant,how to use a few of different communication protocols such as DH+、DF1、Ethernet,MODBUS,OPC in a SCADA system is described and a brief introduction on the main feature of each protocol and the convenience to the end user is presented.

A protocol applied in interactive micro-robot contest platform is examined.

Some connections are discussed of the communication interface of RS-422/485 between DCS and PLC,also the features of the protocol MODBUS and the main content involved are tackled.
