基于MPI的往复压缩机监控系统通信技术研究

The communication technology research of reciprocating compressor monitoring system based on MPI

在Delphi开发环境中,调用PRODAVE S7动态链接库,采用MPI方式实现了大型6缸往复压缩机监控系统的工控机与S7-300系列PLC之间的通信。工程实践表明,该通信方式数据传输速率快、传输准确,对建立大型过程设备的状态监测和故障诊断系统具有很好的参考价值。

The MPI communication between IPC and S7-300 series PLC of the monitoring system of large-scale 6M-style reciprocating compressor has been achieved by using the PRODAVE S7 DLL on the environment of Delphi. The engineering practice shows that this communica- tion method transmits data fast and correctly and has good referenced value for the condition monitoring and fault diagnosis system of large-scale process equipment.
