have a control that has a dll for VB. Can this be used in LabView?

[Dawn 147]

I have a controller that has the dlls to communicate to VB via ethernet. Is there a way to utilize this in labview? Is this the most efficient way to do this? We also have OPC and modbus capablities, but I'd prefer to use the dlls since they are more "proven"

Hello Dawn,

LabVIEW can call into dll entry points using the Call Library Function Node (in the Advanced palette).

If your dll has an ActiveX interface (dual or dispatch) LabVIEW can also handle that using the ActiveX Automation Nodes (in communications>activex palette).

If the above does not work for you please write back describing your problem and the interface to your dll.

Sincerely,

Mahesh.
