interfacing PLC siemens S7_300 and LabVIEW DSC using siemens OPC server

[Salvino]

Does anyone already interface Siemens PLC S7_315-2-DP with LabVIEW DSC using Siemens OPC server?
Is that a good solution? Are there any hidden problems?

The use of an OPC Server is the way to go when dealing with LV. If you already have Siemens OPC Server then use that. Otherwise, NI has a product called IA Severs/Lookout Protocol Drivers (LPD), which has a large selection of drivers for PLC's. After configuring the driver, LPD is the OPC Server for the device.
