Improved control and monitor two different PLC using LabVIEW and NI-OPC server

<span>This paper proposes an improved control and monitors between two different PLCs, the Mitsubishi, Omron. The main advantage is interoperability communication both PLC. use of NI OPC server as software interface reached communication. There were developed field applications to test interoperability. Laboratory virtual instrument engineering workbench (LabVIEW) uses application for creating user monitor. This improvement show technology solves data compatibility issue driver controller’s reducing development cost. Regardless whether there are more than it's enough server. So benefit not limited types PLC used right now but can also other manufacturers. Besides, previous study LabVIEW makes from displayed realistic. allows additional monitoring functions, one which vision. Data utilization becomes flexible, so it complex purposes. It envisaged that this very useful Integrator engineer implement method in industrial automation</span>
