Does anyone know how LabVIEW communicate with GE PLC 90-30 using Ethernet? Are there any built VIs that can be used for this purpose? Basically what I want to do is to get data from PLC and display in graph in PC and store the data. Pleae help. Appreciate any helpful information. Thanks!

The NI OPC server CD provides an OPC server for GE Fanuc Series PLCS over the ethernet link.  There are also other OPC servers for the GE PLCs:
