eoin Posted January 24, 2008 Report Share Posted January 24, 2008 I need help getting labview to communicate some digital and analogue I/O over ethernet to a gateway which then communicates with profibus. How to go about getting the Values in my labview VI to communivate over ethernet????? Quote Link to comment
David Wisti Posted January 24, 2008 Report Share Posted January 24, 2008 You could use Modbus TCP for the Ethernet communication. NI has a Modbus library or you could use shared variables with Modbus I/O server. AFAIK, you do not need DSC or RT to use Modbus I/O server in shared variables. Or, you could get LabVIEW talking on Profibus directly without any gateway.

Ethernet is pretty vague as it's a hardware protocol. What software protocol does your gateway use to communicate? It could be EthernetIP or ModbusTCP or something in swahili. Does the gateway have an OPC server? Tim Quote Link to comment

OPC shouldn't be hard. If you open up the NI Example Finder and search for OPC you'll find several examples, plus there's shared variables. Tim Quote Link to comment
