Aiming at the problem that single man-machine interface is difficult to monitor running state of multiple PLCs in automation system, a feasible and effective approach to network monitoring is proposed. At first, the communication network for PPI between multiple PLCs is built. So each PLC becomes a site in the network. Furthermore, in order to monitor each PLC site in the network by monitoring the entire network, the entire network for PPI is configurated under the MCGS configuration environment. Finally, with the platform for DLMPS-727S2, the experiment based on the above idea is done. And the result shows that the system can simultaneously monitor multiple PLCs, and is high reliability and real-time, and it has good application value. [ABSTRACT FROM AUTHOR] |
