And I want to know if that VI can be used in a loop to enter the data and save the node paths generated. The OPC-COM module provides the ability to connect to OPC servers that only communicate using the older COM based OPC-DA standard. Toolkit supports OPC Data Access 1.00, 2.05a, 3.00. I know there is an OPC UA vi that tranform node name array to node path but I am not able to reach a compatible data type input for it. Graybox OPC Server Toolkit lets the programmer to create robust and highly effective OPC Servers within the shortest possible time. By calling the IP address of PLC, the data from the process are monitored and controlled using the ENI-W utility web page. The serverclient architecture is established through NET-ENI which has standard TCP/IP communication protocol stack. So far i was able to exctract data as cluster of array of strings. NI-OPC server interface with PLC based cascade control system. In other words, if I have a list of 100 folders/items/properties arranged in an excelsheet or any type or data file, how can I define them using my OPC UA server on labview?
NI OPC SERVER DOWNLOAD CODE
But creating folders and items manually for each new folder and item we want to enter takes time and space in my code so I decided to extract the information from an excel sheet. As a test start, I was able to create a data structure of three folders with items and properties corresponding. Widely used OPC Simulation Server, compliant with DA 2.05, DA 3.00 and AE specifications, and also. I see you have good experience with OPC UA labview. The Siemens S7 PLC OPC Server from Matrikon OPC provides industrial strength connectivity to the S7 family of PLCs (S7-200, S7-300, S7-400, S7 1200 and S7 1500 series) via Ethernet. I am working on a project at my university that is based on OPC UA labview data toolkit.
