Connecting to LabVIEW to L23E Compact Logix Controller

[Roxassaraus]

Is there a way to connect LabVIEW to PLC (L23E Compact Logix Controller) without using NI OPC Server?? Please help me in this regard.

Thanks,

Sunil,

The answer to your question will depend on the communications protocols supported by your PLC. If your PLC only supports OPC communications, then this is what you will have to use. If the PLC uses the OPC protocol AND has a built in OPC server, then you won't need the NI OPC server. If, the PLC does not have a built in OPC server, then you will need one - either NI OPC or one from another vendor.
