Modbus over Ethernet/TCP Regards, joseph Tagg

[ottifant]

A LabWindows application should communicate with an Matrikon OPC Server via Modbus TCP.

Has anybody experience with that theme? Does a tutorial exist?

The LabWindows application  and the Matrikon OPC server exist. The gap, the communication

between them, is our challenge. If you have experience with it, you can contact me, please.
