Software interface reached interoperability and communication.

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